However, unlike many people's imagination, the United States has never reduced or blocked China in terms of civil aviation engines. Many people don't understand why the United States is so generous in this regard, selling the aviation development, which is known as the flower of industry, to China and continuously supplying it? Some experts believe that this is not an American conscience discovery, but because of the following three reasons.
First of all, , as a typical high-end industrial product, it is extremely difficult to manufacture aviation. Even if you get an engine sample, it is difficult to imitate. The most typical case of is the "Qinling" engine. In 1976, my country and the United Kingdom reached a cooperation to conduct research and development and trial production of the "Speey" MK202 engine after obtaining authorization. However, it did not start mass production until 2003 and named it "Qinling" with an interval of 27 years. This was done with the British side providing complete drawings. One can imagine how difficult it is to manufacture aero engines.
Compared with military aviation engines, the manufacturing requirements of aviation engines used in civil aviation are stricter. In addition to thrust requirements, fuel consumption must also be considered. There needs to be a perfect balance between the two. After all, the ultimate goal of civil aviation is profit. Moreover, the ducts of civil aviation engines are relatively large, and the requirements for engine blades are high, and the error should not be too large. This poses a huge challenge to the blade processing technology and involves a wide range of industries, such as metallurgy, materials science, etc. The requirements are also high.
Secondly, , civil aviation engines are inseparable from civil aviation passenger planes. You buy an airplane with its own engine. It's impossible to just sell an empty shell, right? Moreover, the world’s large wide-body passenger aircraft are monopolized by Boeing of the United States and Airbus of Europe. The technology is mature and the safety performance has been tested for many years. Nowadays, not buying the aircraft produced by these two companies will cause passengers to worry about safety performance. Now that the planes are sold, there is no need to hide the engine.
and finally , upgraded to the national strategic level, the United States sells civil aviation engines to foreign countries, can make other countries dependent on engine imports, thereby discouraging the enthusiasm for research and development of local engines in other countries, which can ensure the United States' leadership in the engine field status. After all, the price of buying a engine is much cheaper than developing a new engine, and the uncertainty of independent research and development of the engine is also great, so for many small countries, why not do it?
However, the formation of this situation has certain risks. In addition to squeezing the living space of local engines, it will also make the dependence on similar products overseas continue to increase, which will be subject to others. Once "choked" by the United States, the blow will be enormous. This is also one of the reasons why my country should vigorously support local innovative industries. From scratch, from zero to one, can we improve our ability to resist risks and avoid being controlled by others.
