As we all know, aero engines have always been a shortcoming restricting the development of China's aviation industry. Of course, there are various types of engines in China, and the performance may not be good enough, but we started late after all, and we suffer from the weakness of the aviation industry. However, my country’s turbofan 15, turbofan 20, and turbofan 19 are currently being developed in China. It is optimistic that the turbofan-19 will reach the level of the US F414 and EJ200 and will become the engine of my country’s medium-sized fourth-generation aircraft. The turbofan 19 will It is the key to our country's surpassing of American aviation.
Turbofan-19
For Turbofan-19, its public information is very rare, more mysterious than Turbofan 15, not to mention specific performance parameters and photos of itself. As the target power of my country's medium-sized fourth-generation aircraft, the Internet is full of very optimistic comments about the turbofan-19. The maximum thrust is estimated to be 12 tons, the thrust-to-weight ratio is more than 11, and the installed targets are medium-sized aircraft such as the F-31 and Xiaolong. This data is actually quite reasonable for the current status of my country's aviation development. As we all know, my country's aviation development field has a weak foundation, and the overall level is still very far behind the United States, Russia and Europe. Regarding high-thrust turbofan engines, at least there are two complete models of turbofan 6, turbofan 10, and the development experience of mid-thrust turbofans is even weaker.
Domestic aviation development
In the 90s of the last century, my country’s core aircraft was developed in the field of aviation development. However, due to a series of reasons such as capital, technology, and installed targets, the medium-sized turbofan only reached the core aircraft stage, and did not go through the complete development process, let alone Said to be perfect in actual equipment applications. In the 21st century, in order to provide a backup engine for Xiaolong, Guifa Institute surveyed and copied the Russian RD-33 and obtained the turbofan-13 model. As the target power of the medium-sized fourth-generation aircraft, the performance of the turbofan 19 must surpass that of the turbofan 13 in all directions, with a maximum thrust of about 10 tons and a thrust-to-weight ratio of 9 or more. Taking into account the capabilities of China Aviation Development, the F414 engine used by the Super Hornet is a very reasonable reference target.
J-10 engine
After the F-31 is equipped with two turbofan-19s, it has a huge advantage over the F35 in terms of thrust. In terms of avionics, the domestic technology is not inferior to that of the United States. On the whole, the complete J-31 is enough to contend with the F35. At the very least, the top equipment of my country's naval aviation is not inferior to its opponents. This is also the significance of the development of the turbofan-19 aeroengine. Otherwise, if only the Russian-made engine is used, not only the thrust is not as good as it is, but it is also controlled by others. With the turbofan-19, the J-31 wants as much as possible, and there will be no shortage of output due to engine problems. In addition, the Xiaolong fighter is also the target of the turbofan-19. After using the turbofan-19, the mobility of the Xiaolong fighter can be improved, and foreign trade will not be controlled by others.
Domestic aviation development
As for the progress of Turbofan-19, everyone still has to be patient. The turbofan-19 project was established late, and the resources obtained are not as good as those of the turbofan 15, and its development progress will certainly not be earlier than the turbofan 15. It is very good to see the turbofan-19 in batches before 2030. Facts have proved that the weak aviation industry and lack of relevant experience have become important constraints for the future development of domestic aviation development. Buying is worse than buying, and renting is worse than buying! Endless troubles! Although there is a difference of about 20 years from the advanced engines of the United States, I believe that China will definitely catch up in the near future and solve this constraining problem. Come on, China!
