Aviation engines have a very strong ability to promote related industries in a country. If it can effectively promote technological development, related industries will benefit. How can it be said to be useless? In addition, whether a project is worthless depends on the person's determination and the feasibility of the plan. The project itself is feasible, and if you are determined to build it and build it well, then it is not useless.
Although China has been imitating for a long time, it at least has the production and research and development foundation of engines, which is a few steps ahead of India. China has made great determination in the "Taihang" project. It has been said before that the reliability is not high, but now it not only has prototypes, but has also been produced in small batches to equip the troops. It can be seen that its performance indicators are already quite good, otherwise it would not be possible In terms of feasibility, China's targets for Taihang are not very high when it comes to equipping its troops, which is the level of the United States and Russia 20 years ago. It is completely achievable. In addition, China is also very cautious when introducing foreign technology. It does not say that it will turn to foreigners when it encounters problems that cannot be solved. It still attaches great importance to independent research and development.
Looking at India, it has been developing engines for almost 30 years. "Kavli", or "Kavri", only has a few prototypes so far, and no one dares to use it. In terms of research and development ideas, the Indian military does not start from the basics and vigorously develop basic technologies. It just focuses on the engine itself. Even if it succeeds this time, it will encounter the same problems in the future, such as test benches. This is what must be done to develop engines. , and India does not have a high-altitude test bed and must ask Russia for help. It can be seen that the Indian military does not have a correct idea at all in the research and development of aeroengines. How can it succeed? In addition, the performance indicators of the engine have been changed again and again, from the level of the F404 at the beginning to the level of the EJ-200 and M88 later. This is far beyond what India can achieve, and foreign countries will not provide all the technology. , how can it not fail? The scientific spirit shown by India in the research and development of weapons can almost be ignored. It is completely done wherever it wants. It is not a matter of tastelessness, but simply not researching and committing suicide...
