What is the current status of China's aero engines?

Usually, we think that the research level of domestic aero-engine is about 20 years different from that of foreign countries, but some of these technologies are comparable with those of foreign countries, and they are only limited by the level of material manufacturing process and theoretical foundation, etc., which have a certain degree of gap with those foreign countries in some key issues. But such a gap, through a larger investment in human and material resources and financial resources, it is possible to catch up in a relatively short period of time.

In fact, the so-called gap of more than 20 years, mainly on the model, because foreign countries are now the most cash F119 and F120 turbofan machine has been used in the variable cycle, vector nozzle and other technologies, and foreign turbofan engine is the 1980s around the time of the installation of China's WS9 in the late 1990s to develop and produce successful, WS10 in the early 21st century finalized, the overall and foreign countries of these There is a difference of about 20 years between overall and these foreign turbofan engines' finalization time. However, on our WS10, there are also many places where the design concepts of engines such as the F119 have been adopted, and even concepts that are more advanced than theirs, so it is not possible to simply illustrate the current status of our engines by just the time of finalization.

All in all, our engines are moving towards the international advanced level, at the same time, there are some more advanced, foreign not yet available aviation propulsion theory is being studied, is expected in 2020-2030, China will be able to raise eyebrows.

I hope that we can understand more, support the country's aviation, after all, our country is now alone, behind closed doors, research and development difficulties and costs are very high, coupled with the country's limited resources in this area, especially the high precision industrial base is very weak, so only people from all walks of life are doing well, our engine can really do well, for the Chinese to fight for the glory of the Chinese people
