The aviation engine is known as the crown jewel of the aviation industry, because of its technical difficulty and only a few countries have the ability to develop and produce aero engines. These countries are the United Nations, where the engine technology is represented by the United States and the United States, while France and China are lagging behind. And France is coming closer because of the help of other European countries, the engine technology is developing constantly, and the gap with China will be bigger and bigger. China is now the only country in the five countries that can produce engines but still need to import engines.
Aviation engine technology has always been one of the key problems in China, and its design structure and single crystal blade have become two obstacles on the road of success. Single crystal blade is the core of the aeroengine parts, size and turbofan engine thrust is proportional to the temperature, they can afford to many countries because of the quality of the fan blade withstand the test of high temperature eventually failed. In the case of the F119 engine of the us military's fifth-generation stealth fighter F/ a-22, the engine's inlet temperature is at least 100 degrees higher than that of the previous generation of F110 engines. The U.S. military has developed a new titanium alloy for the F119 to help it withstand high temperatures inside the engine, and one of the most important materials in the titanium alloy is the metal rhenium.
Metal rhenium is a rare metal with high flammability and high temperature resistance. It is an indispensable material for the production of engines in various countries. Currently, the world's known metal rhenium is 2,500 tons, and most of it is in the United States. And all the other countries that were able to extract the rhenium were eventually sold to the United States because they couldn't use the metal rhenium to make the engines. Previously, China had discovered only 200 tons of the metal rhenium, and most of it was sold to the United States. Until recently, China's advances in aviation engines made it possible for Chinese companies to use the metal rhenium to make aircraft engines. But this time the United States because China rhenium consumption too fast, realize that China has made a breakthrough in the engine, and accelerated the global metal rhenium collect ban on selling to China and other countries, trying to the rise of China's aviation engine down.
