NK-32 engine
As the world's top military engine, the NK-32 has become the world's number one military aviation engine with its military thrust of up to 25 tons. This title is still unsurpassed by no one. In order to ensure that this The confidentiality of this engine can be fully guaranteed. Russia will not even disclose a screw about this engine to outsiders. So what are the benefits of the NK-32 engine? Can Russia keep it secret?
The NK-32 engine in Figure 160
Although most of the technologies used by NK-32 are obviously a bit backward at present, this does not mean that the performance of this engine is better than that of the most advanced F119 series engines. Bad: A large supersonic bomber like the Tu-160 can rely on the powerful thrust generated by four nk32 engines to ensure that it has a huge range of up to 14,000 kilometers, or it can carry out a breakthrough at a high speed of 2 times the speed of sound when necessary. Defense mission, obviously, some of the characteristics of this engine are still outstanding even now.

Because the biggest difference between NK-32 and other military thrust engines is that this is the only military high-thrust three-rotor engine in the world: and even the most advanced American engines like F-119 , will also be forced to use a dual-rotor structure due to volume and process issues, so it cannot achieve perfect adaptation under the premise that different sections of the engine have different requirements for operating speed like the NK-32. Therefore, Although the NK-32 is no longer the military turbofan engine with the highest thrust-to-weight ratio in the world, it is definitely one of the military engines with the best fuel consumption control in the world.
Of course, it is not that there are no other aircraft engines in the world today that use a three-rotor structure, but the only military thrust engine that uses a three-rotor structure is the Russian NK-32: because the NK-32 is an engine for bombers , it has a larger volume than other fighter engines, and the requirements for a series of processes such as engine production precision are also smaller than those of engines with the same harsh operating environment. Therefore, Under the premise that Russia's ultra-high temperature alloy technology is equally excellent, they can complete the production of the NK-32 engine, making this engine the only military jet engine in the world that uses a three-rotor structure.
F135 engine
Fighters from other countries, including the F-119, use large jet engines. Due to their relatively small size, this series of engines must make trade-offs among maintainability, cost and performance. Even the American B The F101-GE series engines used by -1 "Lancers" were also forced to make compromises due to the size limitations of their own core machines and continued to use a relatively mature dual-rotor structure, making the NK-32 engine the most powerful at the time. Same level engine.
But as modern dual-rotor engines continue to advance, even Russia’s most advanced “Product 30” engine has reached 22 tons of thrust, and the American F135-PW-100 engine itself has more than 20 tons of thrust. Afterburning thrust, this means that the NK-32 engine will no longer be the most advanced engine in the world and cannot be surpassed even with today's technology.
