China's industrial strength and aviation technology are very strong. Industries such as public security, firefighting, disaster relief and rescue have extensive demand for helicopters. Therefore, the country attaches great importance to the development of the helicopter industry and has formulated a strategic development plan for the industry. , now another good news has come from the country. China’s Lucky Bird large civil helicopter has successfully made its first flight. As a 13.8-ton large helicopter, it has filled a domestic gap and China Aviation Rescue has refilled its weapon. So what are its extraordinary abilities?

in Jingdezhen, Jiangxi, The successful first flight of the Auspicious Bird AC313A large civil helicopter developed by Aviation Industry Corporation of China marks that China has the international third-generation large helicopter research and development technology, filling the gap in domestic large helicopters, making China and Europe, the United States, Russia Likewise, becoming a producer of large civil helicopters can expand business in the international market in the future, and at the same time meet the demand for large helicopters in the domestic market, solving the problem of the lack of large helicopters in the fields of rescue and disaster relief and public security and firefighting.

Helicopters have very obvious advantages. Compared with fixed-wing aircraft , the maintenance conditions are more convenient, and the speed can reach 200 kilometers per hour. It is known as the "Air Emergency Express" and has unparalleled capabilities. Superior show, this is the main reason why the United States used a large number of helicopters during the Vietnam War, Afghanistan War, and Iraq War. In previous domestic earthquake relief activities, foreign-produced helicopters were mainly used. However, some disaster areas reach an altitude of 4,200 meters, and domestic helicopters cannot reach this height. The AC131A is a large civilian helicopter that cannot carry a large amount of cargo. It has a water-sprinkling capacity of 5 tons and can transport 28 crew members. Its maximum flight altitude exceeds 5,000 meters. It can fly in hypoxic high-altitude areas and has a long range. Therefore Very suitable for large areas For use in the Chinese market, which has a vast and diverse geology and climate, this helicopter adopts MBD three-dimensional design technology, with a beautiful and smooth appearance and an elegant overall style. It is equipped with a high-power engine based on the AC313, which improves the power of the transmission system and the life of the engine.

. It is equipped with more advanced avionics, flight control, electromechanical equipment, and is equipped with rotor de-icing equipment. In order to ensure the success of this first flight test, the helicopter was on the ground before taking off. The test bench has conducted dozens of tests including power system debugging, temperature measurement, ground resonance test, tail slurry coupling stability test, rotor power transmission torsional vibration frequency test, etc. After ensuring safety and reliability, the The first flight test is expected to complete sea trials and all tests in 2023 and be delivered to users. Data shows that the current number of civilian helicopters in the world has reached 37,000, but most of them are light, small and medium-sized helicopters. The main reasons for the lack of large helicopters are that the technology is too difficult for ordinary aircraft companies to develop and produce, and the second reason is that they are too difficult to develop and produce. The users are mainly some national institutions, which have very strict performance requirements for helicopters. The AC313A Lucky Bird Seat is a large helicopter with advanced third-generation helicopter technology. It can well develop domestic and foreign markets. The market potential of this helicopter is very large. The status is not inferior to C919.
