is well known that for modern fighter aircraft, the most important component is the aero engine, which directly affects The combat level and maneuverability of a fighter is the highest expression of the combat level of a fighter.
can also be said to be the heart of the fighter. From the day of the birth of the fighter, the engine is the most critical factor in determining the performance of the fighter. In order to improve the combat level and air combat performance of its own fighter jets, the country has never stopped its competition in the field of engine research and development.
and this kind of competition has exceeded his original scope, and has become a material and basis between countries. The contest between science, scientific research strength and other fields. Beautiful lines and surging power have always been the creed of American aircraft designers. American designers firmly believe that as long as the thrust-to-weight ratio is greater than one, the bricks can fly into the sky.
In fact, they It is indeed the case. In order to improve the flight speed and altitude of the fighter, all the research and development costs and energy are devoted to the life of the fighter, so it has a service life of 4000 hours. Today, the United States Aeroengines have been leading the world, not only because of their high thrust but also a long service life. Despite this, the U.S. military has not stopped its development. After successfully developing the F119 engine, the U.S. For the prototype, he developed and designed the turbofan aeroengine with the largest thrust in the world. Although the core components are the same as the F119, the turbofan engine's secondary combustion chamber is further enhanced to enhance the rotor's impact on the driving load. Withstandability.
After this improvement, the service life of the US military’s aero engine has reached nearly 10,000 hours. It can be said that it is the strongest aero engine on the surface. The Soviet Russian aero engine is deeply affected by the Soviet designer’s Engines are consumables and used less once a day." The old idea that the service life of aero engines is even less than half the service life of American aero engines. In fact, this is also in line with the foundation of the Russian aviation industry. Relationship, after all, not so wealthy Americans, do not have sufficient funds to develop durable aero engines, so I always feel that the engine is a consumable, once used for one less time, there is no need for "life-increasing treatment."
Aeroengine technology started much later than the United States and Russia, but it is also a veritable rising star. We know that we cannot all design and research in accordance with the Soviet aeroengine model. Therefore, we can remove the dross and extract the essence on the basis of the Soviet Russian aeroengine. Aeroengines with Chinese characteristics, but we still have a huge gap compared with American aeroengines. After a certain flight time, we still It is necessary to conduct a thorough physical examination of the aircraft's engine, unlike the American engine, basically no problems will be found in the first time, and the modular treatment is carried out.
