Does Taihang engine only have a life of 600-800 hours?

The service life of Taihang engine is not only 600~800 hours. The design life of the hot end of Taihang engine is 1500 hours, and the design life of the cold end is 3000 hours, which is about half of the same type of engine of the US military.

Western media believe that after adopting a series of new technologies, Taihang engine can increase its thrust by about 1.500 kg without major structural changes. In other words, the improved Taihang engine can reach a higher design index, that is, the afterburning thrust can reach about 14 tons, which is obviously better than the Russian-made Al-3 1FN engine with 12. Roughly equivalent to the Russian-made 99M2 engine, it can even be used to equip the J-20 fighter in the future, and its service life will reach 2,500 to 3,000 hours, which is close to half of the development of American aviation.

Significance of prolonging the service life of Taihang engine;

The successful development of Taihang's improved engine provides power guarantee for the development of domestic third-generation combat aircraft and strongly supports the improvement and modification of these aircraft. In the case that J-1 1 series has lost the source of Russian power system, the improved engine of Taihang is very valuable, and the subsequent development of J-15, J-1/D and other models can not be separated from the improved engine of Taihang.

The J-10B fighter plane adopted Taihang's improved engine, which achieved the goal of "one aircraft supporting two aircraft" set in that year, and AVIC people continued to forge ahead courageously in stumbling.
