helicopter plays an important role in national construction

my country's unique natural environment and current social development status. Compared with other countries in the world, helicopters play an important role in my country's national defense and national economic construction. my country has a long border, a complex geographical environment, a arduous task of border patrol and guarding, numerous plateaus and mountains, rivers crisscrossing, and frequent natural disasters. At the same time, vast forests and grasslands also need patrol and protection. In national construction and social development, my country is facing problems such as maintaining social stability, combating terrorist activities, and narrowing the economic gap between the east and the west. At the same time, it is necessary to meet the people's good wishes for high-tech products to be closer to daily life. Therefore, from national defense construction, anti-terrorism and stability maintenance to emergency rescue and disaster relief, emergency rescue, to agricultural and forestry operations, geological exploration, to tourism and flight training, the application of helicopters has penetrated into all aspects of society.

my country's helicopter market has huge potential

According to the forecast of China Aviation Industry Development Research Center , by 2027, the scale of China's civil helicopter will reach more than 3,500 aircraft, and the market capacity of the helicopter production and sales links alone will reach US$14.4 billion. According to the input-output ratio 1:8, it will leverage nearly one trillion market, and its sales growth of 1% will drive 0.714% of the national economic growth.

helicopter industry has strong industrial driving capabilities

helicopter industry chain is long, including upstream and downstream industries, covering almost all industrial categories, integrating nearly 100 sciences and more than 1,000 technologies. The development of the helicopter industry requires technical support from all walks of life, and this is also an opportunity to drive the development of related industries. Using the trillion-dollar market size of the helicopter industry and taking the development of the helicopter industry as the guide, it can drive technological innovation in related industries and realize industrial transformation and upgrading.

helicopter has good common characteristics of military and civilians.

helicopter is based on platform research and development, and specific functions can be realized through modification and modification. Therefore, from the perspective of platform research and development technology, helicopter technology is very replicable. The universality of the helicopter application field is fully demonstrated in emergency rescue and disaster relief, and the performance of military transport helicopters in emergency rescue and disaster relief operations is enough to illustrate everything. Police helicopters are the best example of military-civilian cooperation as powerful weapons to maintain social stability and combat crime. Therefore, the development of the helicopter industry will surely become a new high point in the development of military-civilian cooperation in my country.

This article analyzes the current development status of the helicopter industry at home and abroad, summarizes the measures of European and American countries in helicopter market development, technological innovation and development, product innovation, supplier system construction, industrialization layout, etc., analyzes the current development status and problems of my country's helicopter industry, and puts forward suggestions for the development of the domestic helicopter industry.

1. Current development status of the world helicopter industry

1.1 Necessity of development

As of the end of 2019, there were more than 54,000 helicopters in use worldwide, including about 32,000 civilian helicopters and about 22,000 military helicopters .However, the global distribution of civil helicopters is extremely uneven. North America has about 12,000 civil helicopters and Europe has about 7,000 civil helicopters, and the number of the two accounts for about 59% of the total global civil helicopters.

Figure 1 World helicopter market distribution

Fig.1 World helicopter market distribution

Among the 22,000 military helicopters in service around the world, the United States has 5,809, accounting for 26.47% of the global military fleet; Russia has 1,572, accounting for 7.14% of the global military fleet. These two countries, together with seven other countries including the United Kingdom, France, Germany, and other seven military helicopter equipment, formed the world's "No.1 Group" of military helicopter equipment, with a total of 11,275 aircraft, and the total equipment accounted for 51.25% of the global military fleet.

Since 2015, the number of civil helicopters delivered in the world has always remained at around 1,000, of which 976 civil helicopters were produced in 2018, with a total market output of US$3.66 billion. Affected by the decline in the number of piston helicopters delivered, the delivery volume in 2019 was 819 aircraft, a decrease of 16.3%.

1.2 The world helicopter stage is in a three-legged position, and the rising stars are catching up with

At present, nearly 20 countries in the world can produce helicopters. Helicopters have become the dominant industry of Western countries and are an important area of ​​technological and economic competition in the United States, Europe and Russia. Countries such as Japan, South Korea, India, Brazil , and Poland have also listed the helicopter industry as a strategic industry in the 21st century and are competing to accelerate their development.

The United States is currently the world's largest helicopter producer and user country, with the world's largest helicopter market and three major helicopter manufacturers: Sikorsky, , Bell, and Boeing . But in recent years, the United States' global leadership in helicopter technology has been strongly challenged by Europe. European helicopter industry is well developed, especially in the development, production and service of civil helicopters, which are at the forefront of the world. In 2019, in the world's civil and quasi-military market, Airbus helicopter market share was as high as 54%, and Leonardo helicopter market share was 23%. In many aspects such as civil helicopter technology, Europe has already shown a trend of surpassing the United States, and has already clearly put forward the goal of putting its aviation industry in an advantageous position by 2020. Since the economic crisis in the 1990s, the production and export of helicopters have continued to decline, but in recent years, Russia's helicopter manufacturing industry has achieved certain growth, with many military helicopter modifications and new models, and civilian products have also developed.

At present, major helicopter manufacturers are responding to fierce market competition according to their respective different business strategies. Airbus Helicopters has achieved success in the civil and military markets through balanced development of production lines, and has covered the world through regional subsidiaries and partnerships. Leonardo has invested a lot of money in new product research and development, while strengthening risk cooperation. Bell Helicopter Company will focus on improving and developing in product , and will be committed to user maintenance and guarantee. Boeing Helicopters focused its production line on a small number of very successful military models. Sikorsky has an advantage in the military market, successfully develops corresponding models in the civil market for specific fields, and obtains profits in the parts market. Robinson has an advantage in the piston helicopter market and is entering the field of light single-engine turboshaft helicopters through R&D intentions. The Russian Helicopter Company continues to integrate its design, production, sales and after-sales service system , and has begun to selectively develop products.

1.3 Helicopter technology innovation in the world is constantly achieving cross-generational development

Currently, helicopters are in the stage of continuous technological innovation, and market demand is constantly promoting the progress of helicopter technology. At present, conventional configuration helicopters have begun to develop from third-generation products to fourth-generation products, and most of the products put on the market after the 1990s fall into this category.The latest models include the H160 and Bell 525 helicopter of Airbus Helicopter Company (hereinafter referred to as Airbus Helicopter) H160 and Bell 525 helicopter . The former will give full play to the extreme of automatic control and intelligent technology, while the latter will become the world's first civilian helicopter equipped with telex flight control. At the same time, the fifth-generation new configuration rotorcraft technology with high speed as the main feature is accelerating the development. The evidence collection work of AW609 tilt rotorcraft has entered the final sprint stage. In addition, some light and small unmanned helicopter products have also been put on the market.

1.4 Helicopter manufacturers accelerate product system construction

In order to occupy the helicopter market share and establish product system advantages, world-renowned helicopter manufacturers pay great attention to product series development in the process of development, and continue to innovate to accelerate the launch of new product . As one of the best helicopter manufacturers in the United States and even the world, Bell Helicopter Company has a complete product system, with helicopter tonnage from 1t to 8t, and nearly 20 rotorcraft product models including V-22 tilt rotor with a maximum take-off weight (mass) of 27400kg.

, the Sikorsky Helicopter Company, which is famous for its S-70 "Black Hawk" helicopter , has more than ten helicopter product models from 794kg to 19t.

After years of development, Airbus Helicopter Company has grown from 1t to 11t. The latest H160 helicopter is a representative of advanced civilian helicopters, demonstrating the strong strength of Airbus Helicopter Company.

Leonardo Helicopter Company successfully opened the door to the world helicopter market with its AW series helicopters, and is a model of systematic construction and brand management.

Relying on its unique Soviet helicopter industrial system, Russia has established a low-cost and high-efficiency brand effect . Its Ka series and Mi series helicopters have an advantage in the international military helicopter market. The m-26 helicopter has a world record of 56t's maximum take-off weight, showing the world the super strength of the Russian helicopter industry.

1.5 The construction of the supplier system is accelerating, and industrial advantages are formed. As the birthplace of modern aviation, European and American countries have very sound machine production and supplier systems. Well-known suppliers around the world include Rockwell Collins, General Electric, Honeywell, PrattWhitney, European Safran Group, Thales Group, etc., which can provide all products including engines, hydraulic system , power system, advanced avionics equipment, etc. for the development of the helicopter industry; in addition, there are Belgian Solvay, which can provide composite materials, Hexcel, Fredrickson, and Toray, Japan; Spirit Aerosystems, which can provide structural parts, Mitsubishi Heavy Industries, Japan; B/E Aerospace, which can provide interiors and fasteners. A strong supplier group is the guarantee for the continuous development and growth of the European and American helicopter industry and stands at the peak of the world's helicopter industry.

1.6 Improve the customer service system , upgrade the industrial layout

Contemporary airlines' services to users are far more than after-sales service, but extend to all aspects including technical support, financial services, usage and maintenance, training, flight and ground information. Through the customized maintenance support service package, Airbus Helicopter Company improves aviation material ordering procedures, order tracking, inventory management and close-range services, establishes aviation material warehouses and distribution centers, and optimizes aviation material distribution. Sikorsky Helicopters has developed more than 1,000 certified supplier information management systems, established component exchange projects, and established original equipment manufacturer (OEM) component support. Its Sikorsky360 fleet management program brings together the special analysis process of OEM and modern data management technology to enable customer service to go from passive response to active support. Leonardo Helicopter Company has established an extensive maintenance center network OEM repair services, component protection agreement (CPA), complete overhaul and material projects (COMP), global support program (GSP), etc., and has established a aviation material bonded warehouse covering its full range of helicopters in Shanghai Free Trade Zone, providing guarantees for the company's helicopters operated in China.Russian Helicopter Company has set up an after-sales service center in South Africa to provide paid repair services to helicopter customers in African countries. The Russian Federal Government encourages cooperation with China in its national plan to develop light helicopter . China Yitong Group and Russian Helicopter Holdings have signed overseas complete machine production and assembly projects. Institutions in Shenzhen, Shanghai, Chengdu, Qingdao and other places have discussed the establishment of a maintenance center with Russian helicopter Holdings. These measures all show the determination and will of Russian helicopter Holdings to establish a global after-sales service system.

World helicopter manufacturers have increased bargaining chips for the competition for the world helicopter market by establishing a more complete and wider customer service system, improving service quality and improving industrial layout.

2. Current status and problems of the development of my country's helicopter industry

2.1 Current status of national development

(1) Social and economic environment

My country is the world's largest population country. Based on its huge population base and the third largest land area in the world, my country also has a huge scale that surpasses other countries in social and economic development. By the end of 2019, highways in mainland my country reached 14.96×104km, high-voltage transmission lines reached 132.54×104km, and oil pipelines and natural gas pipelines exceeded 15×104km. In the process of national development, the economic situation in the eastern and coastal areas is generally better than that in the western regions, and its economic advantages are obvious. However, considering that the western region is vast and sparsely populated and the wide distribution of natural resources, it is imperative to achieve great economic development in the western region. In addition, with the gradual deepening and expansion of my country's "Belt and Road" economic construction, strengthening the construction of the economic belt, safeguarding national interests, and safeguarding the safety of national lives and property has become another important issue before our country.

(2) Natural environment

my country's land area is about 960×104km2, the land border line is about 2.2×104km long, and the coastline (including island coastline) is about 3.26×104km long. The forest area in my country is about 2×108ha, the grassland area is nearly 4×108ha, and the total length of rivers in my country is 43×104km, which creates a natural environment with a variety of terrain structure, complex geographical environment, crisscrossing rivers and scattered lakes. In addition, two-thirds of my country are plateaus, sub-plateaus, and mountainous terrain. From the perspective of protecting the natural environment, economic construction should reduce the damage to the natural environment. At the same time, considering the impact of the complex geographical environment on transportation, a flexible and changeable three-dimensional transportation system should be developed.

(3) Living environment

The changing international situation has put the living environment around our country under tremendous pressure. Foreign foreign instability factors in China, India, China and Japan, the Korean Peninsula, East China Sea / South China Sea and other regions, and the arduous tasks of maintaining social stability such as the internal Taiwan Strait, counter-terrorism and stability maintenance, and combating separatism have made the factors that my country needs to consider in the construction of weapon equipment system more complex.

From national construction and social development to western development, from overcoming the adverse effects of the natural environment, to establishing a three-dimensional transportation system, from the pressure of the external living environment, to the construction of an internal public security system, in order to maintain national security unity, social stability, and economic prosperity, my country needs stronger helicopter industry support in the development of military equipment, public security forces, emergency rescue capacity construction, and general aviation industry construction. With its unique flight method, the helicopter industry will better serve national construction conditions with less resources.

2.2 Development history of my country's helicopter industry

my country's helicopter industry was founded in the mid-1950s. In October 1956, the -meter-4 helicopter was introduced from the Soviet Union and started to produce the straight-5 helicopter , which started the development process of China's helicopter industry. Then, by introducing and producing the Z8 and Z9 helicopters, the Z11 helicopter was designed and developed by itself. China's helicopter industry has always adhered to the policy of "one aircraft, multiple types, series development" and "independent development as the main focus and active international cooperation". It has transformed dozens of models from existing organic models to serve the land, navy and air force, social welfare and national economic construction.In particular, the development and production of Z-10 armed helicopter and a certain type of transport helicopter have enabled my country to develop and produce third-generation helicopters, and to establish the development capabilities of fourth-generation helicopter , laying the technical and material foundation for industrial development and forming a leapfrog development situation.

2.3 Helicopter equipment

For a long time, due to weak foundations and strict control of low-altitude airspace , my country's helicopter equipment is still in its infancy and its fleet is small. As of the end of 2019, my country's civilian helicopter ownership was 1,237, with an average of 0.90 per million population, of which there are only 53 helicopters produced in China, accounting for less than 4.3%. A large amount of market share was seized by European and American manufacturers. The weak development of the domestic helicopter industry has caused the embarrassing situation where the domestic civil helicopter ownership is small today, and domestic helicopters have almost no foothold in the field of civil helicopters.

Since the reform and opening up of , the country's economic construction has developed rapidly, the scale of infrastructure construction has been huge, and the entire society has experienced earth-shaking changes. However, the helicopter industry, which should have played an important role in this period, has developed slowly, especially in the field of civil helicopters. In order to achieve the country's goal of accelerating industrial upgrading and transformation and reaching the level of in medium-developed countries by 2050, it is necessary to accelerate the development of the helicopter industry, and promote the transformation and upgrading of the helicopter industry based on the development of helicopter technology, product development and market development.

2.4 Technical system construction

World helicopter technology comes from Europe and the United States. my country has always been learning and tracking advanced helicopter technology in Europe and the United States. In the past decade, the development of helicopter technology in my country has accelerated significantly, and now it has basically formed the technical foundation for the development and production of contemporary helicopters and the industrial foundation for industrial development. We have mastered the overall design and optimization of helicopters, aerodynamics, dynamics, structural design and other helicopter design technologies. We have established an effective scientific research management system for various helicopter systems from design and research to testing. At the same time, we are also paying more attention to the development of cutting-edge helicopter technologies, including intelligent rotors, composite helicopters, helicopter electric technology, high-speed helicopters, etc., to maintain the advanced nature of my country's helicopter technology. my country's helicopter technology system has basically formed a good development momentum of one generation of argumentation, one generation of development, and one generation of production.

However, my country's investment in basic helicopter technology has been insufficient for a long time. The basic testing facilities used to explore the basic principles of helicopters are incomplete. Many theories cannot be verified and developed continuously. The construction of the technology system is significantly lagging behind European and American countries. At the same time, my country's military helicopter models are developing slowly, and the demand for helicopter technology is not urgent enough, which leads to sluggish and backward in technological development, insufficient innovation capabilities, and the inability to support the research and development of new models. This cycle has led to the slow development of my country's helicopter industry and lacks advantages in the fiercely competitive helicopter market. The generation gap of helicopter military equipment is a major weakness in national defense construction. Therefore, accelerating the development of helicopter technology is an important link in promoting the development and growth of my country's helicopter industry and building national defense modernization.

2.5 Product system construction

After decades of development, my country's helicopter industry has formed a relatively reasonable product structure. The 2t-level, 4t-level, 7t-level, 10t-level, 13t-level and other platforms have completed the design and finalization. On this basis, multiple models developed have entered mass production and delivered to different users. AC series civil helicopters have entered the civil aircraft market one after another, and the 7t-class AC352 helicopter developed in cooperation with European Direct is actively collecting evidence.

However, through this helicopter model number and maximum take-off weight distribution map (see Figure 3), we can see that there is a huge gap between the construction of my country's helicopter product system and European and American countries, and it is very far apart in terms of model number and maximum take-off weight. The lag in product system construction is a comprehensive reflection of the lagging development of my country's helicopter technology and the lag in the development level of helicopter application fields. The construction of my country's helicopter product system needs to be accelerated. Through market development and product research and development, the pace of development of the helicopter industry will be accelerated and the passive situation of my country's helicopter industry lags.

Figure 3 The world's leading helicopter manufacturer's product maximum takeoff weight envelope

2.6 Supplier system construction

my country's helicopter industry follows the military helicopter R&D and manufacturing system. Relying on the China Helicopter Design Institute, Harbin Aircraft Industry Group Co., Ltd. and Changhe Aircraft Industry Group Co., Ltd. , a helicopter supplier system is established with various supporting manufacturers of the aviation industry as the industry, including a complete industrial system of technical research, product R&D, manufacturing, testing and production, and is the main body of my country's helicopter industry.

However, from the perspective of the construction of foreign helicopter supplier system, my country's helicopter suppliers are still in the initial stage of development, especially in the supporting facilities of civil helicopters, their technical capabilities, product quality, and market share are all at a disadvantage and cannot compete with world-class suppliers. Domestic helicopters that are tied to the interests of domestic suppliers are also in a barely survival situation in the competition. Domestic helicopters have poor technical capabilities and lagging product development also make domestic suppliers lack development opportunities. Strengthening the construction of the supplier system and using models to drive technological development is the only way to improve the overall level of domestic suppliers and the foundation and guarantee for the development of the helicopter industry.

2.7 Customer Service and Operation

China's helicopter after-sales service is under the responsibility of the helicopter manufacturer, providing independent and comprehensive after-sales service guarantee. The domestic helicopter manufacturers of a certain scale are mainly Harbin Aircraft Industry Group Co., Ltd. and Changhe Aircraft Industry Group Co., Ltd. Both companies have their own after-sales service systems and provide guarantees for users' helicopter operations by dispatching after-sales service personnel. This model can ensure that the helicopter is in good condition during operation, with after-sales service guaranteed and quick response, so as to facilitate the rapid resolution of problems arising during operation. However, this model also makes it difficult to ensure after-sales service by helicopter manufacturers, especially for small purchases and wide distribution range, the cost and energy used for after-sales service will be greatly increased. The practices of the after-sales service guarantee links in the United States, Europe and Russia are gradually converging. By establishing an integrated after-sales service center and regional after-sales service stations, the service areas are divided, the manpower and material resources are reasonably allocated, the pressure of after-sales service and warehousing is reduced, and the pressure of after-sales service and warehousing is ensured to serve users well.

Operating companies directly participate in market competition, and the survival status of operating companies affects the direction of the development of the helicopter industry. As of the end of 2019, there were 478 enterprises in my country that have obtained general aviation business licenses, with 246 general airports issued with certificates, with annual aviation flights of 112.5×104h. The main business scope includes oil services, flight training, power line patrol , forest protection and fire prevention, etc. However, the overall capacity of my country's helicopter navigation market is still weak, and there is an order of magnitude gap compared with European and American countries, which limits the development of the helicopter industry. Therefore, exploring the application fields of helicopters, relaxing operation restrictions, and supporting operating companies are important ways to open the door to the development of the helicopter industry.

3. Domestic helicopter industry development suggestions

Although my country's helicopter industry has been developing for decades, it has many shortcomings in various aspects such as technology system, product system, customer service system, and supplier system. According to the economic views of Hamilton, the first Treasury Secretary after the independence of the United States, and Liszt, Germany, my country's helicopter industry is still a naive industry with weak foundation and competitiveness. Although the industry appeared earlier, taking into account all factors into consideration, it is still in the early stages of development and needs moderate protection. my country's helicopter industry has a certain foundation, the industrial framework is basically complete, the scientific research and management system has been established, the market is in the process of openness and development, and the prospects are bright. Through policy support, rational industrial layout, promote innovative development, tap the potential of my country's helicopter industry, complete industrial upgrading, and achieve a strong country in science and technology.

(1) With the healthy development of the helicopter industry as its main purpose, we will strengthen top-level design, overall planning, and long-term layout, and promote the coordinated development of various industries. At this stage, helicopter giants around the world are jointly building factories directly or with the support of local governments in my country, and strive to squeeze into and occupy the Chinese market through this method. However, while many places and institutions pay attention to and promote the development of the helicopter industry, some established helicopter companies can only introduce low-end or phased-out products for assembly and production; some local governments vigorously promote joint efforts with foreign companies to establish helicopter cooperation enterprises to assemble helicopters to occupy the domestic market. These phenomena have directly affected the healthy and orderly development of my country's helicopter industry, affected the development of related enterprises and industries, caused huge waste of social resources, and brought adverse effects to the development of the helicopter industry. As an industry with a highly integrated military and civilian industry, such an industrial development trend has also brought hidden dangers to my country's national defense construction.

Therefore, the country should coordinate the development of my country's helicopter industry from a macro level, formulate support policies and fiscal and tax policies, establish practical and effective policy measures, plan development paths, rationalize industrial layout, promote industrial integration, and strengthen industry cooperation. Through overall coordination and reasonable division of labor, strengthen industrial management and promote policy implementation, while achieving the development of my country's helicopter industry, drive the coordinated development of related industries and enterprises, achieve benign interaction, build a healthy and sustainable industrial chain, and create advantages of the helicopter industry.

(2) With the goal of serving national construction and model serialization development as the guide, we will achieve breakthroughs and innovations in helicopter technology

my country's helicopter technology is based on the introduction-digest-absorbing-reinnovation, and finally reaching a new stage of development with certain independent innovation capabilities today. However, due to the long-term implementation of technological blockade of my country by European and American countries, my country has both the weakness of weak industrial foundation and the pain points of insufficient research on basic helicopter technology. In recent years, my country has made great improvements in discipline construction and scientific research capacity building. However, as a tangible industrial product, if helicopters are not developed in specific models, technological breakthroughs and innovations cannot be obtained through academic research alone. Leonardo Helicopter Company, a world-renowned helicopter manufacturer, has grown into a world-renowned helicopter manufacturer through the fierce competition in the helicopter market through the serial development of AW models. Its products are technologically advanced, comfortable, and safe, and have a high brand effect. All other helicopter manufacturers in the world develop helicopter technology through model development and promote the helicopter industry to become bigger and stronger.

suggests that the country will increase support for the development of helicopter models and technical pre-research from the perspective of coordinated development of military and civilians, and at the same time promote the formulation of military-civilian coordinated development strategies for helicopter technology, promote the development of helicopter platforms, formulate development strategies for general helicopter platforms, promote the serial development of helicopter technology, build basic technology transplant capabilities, and build a serial development path for helicopters. At the same time, accelerate the mutual communication and trust between military and civilian standards, and clear obstacles for the coordinated development of helicopters.

(3) Build a public utilities aviation system with domestic helicopters as the main body of operation, broaden the application field of domestic helicopters, and establish a brand image

As a country with a large population, complex terrain and frequent natural disasters, China has developed a country with a rapid development of the national economy, the growth of comprehensive national strength and the continuous improvement of people's living standards, the general public has put forward increasingly higher requirements for the public services provided by the state, and an efficient public service system needs to be established urgently. However, most of the domestic civil helicopter market are products from foreign manufacturers. The direct reason for this result is that my country's helicopter industry has lagged behind in its development, and there are unsatisfactory aspects in many aspects such as technology, products, and services.Therefore, by establishing a national public utilities aviation system based on domestic helicopters, building capabilities that can be used for public utilities such as emergency rescue and disaster relief, public security law enforcement, medical rescue, fire protection, etc., and effectively increasing support for domestic helicopters will not only help promote the development of my country's helicopter industry, but also help the construction of my country's efficient public service system.

(4) Accelerate the implementation of the low-altitude open policy, formulate preferential policies for domestic helicopters at the operation end

As the direct entity participating in market operations, the operator is not only a direct user of helicopter products, but also a stakeholder of market-oriented operations. The good and bad operating environment are directly related to the survival and development of operators, and affect the development of my country's helicopter industry. Accelerating the implementation of the low-altitude opening policy and giving operators more flexible and free operation space can improve the level of profit, expand market capacity, and thus increase the demand for helicopter products. Through the formulation of policies, certain financial subsidies will be provided to operators who purchase domestic helicopters and participate in the operation, and policy preferences will be given to the operation areas they are engaged in, which can provide greater development space for domestic helicopters, allowing domestic helicopters to gradually participate in market competition, and use the market competition model to reversely promote domestic helicopter upgrade technology, innovate products, and achieve true self-reliance and self-reliance in the helicopter industry.

4. Conclusion

The helicopter industry is related to national defense and security, social stability, and economic prosperity, and is an important industry serving national construction. Looking at the development history of world helicopter manufacturers, the development and growth of the helicopter industry cannot be separated from the support of the country. Top-level planning for the development of the helicopter industry from the national level, formulating development routes, and clarifying the development direction are the only way to strengthen my country's helicopter industry. With the goal of serving national construction, the guidance of serial development, and technological breakthroughs and innovation as the entry point, we will open up the market, accelerate reforms, and safeguard the development of the domestic helicopter industry.
