The basic model of 20 is no longer producedChinese air forceThe main force is 20a. A recent article published on the foreign military observer website detailing the speed of replacement of 20a in the ranks of the liberation army, which is the ultimate standard version of the 20 warplanes。
The early destruction of 20 was flawed, when the pressure on our air force was very high, the united states already had two five-generation planes, and russia's five-generation planes were intensifying their research and development, and the first flight took place on very short notice. All the sub-projects developed at the time, such as the 20-carrying power, radar, aerodynamics, invisible materials, were completed, as was the case for a sports car, which had been built with wheels, chassis, steering wheel, and casings, but could not drive without engines. At that time, chinese engine technology was not working, and the gap with foreign countries was at least 30 years。
We can only choose the russian-made al-31f engine, which is reliable, technically mature, and the only thing that is missing is that it has a much shorter cycle of overhaul than the western-american vortex engine and has a short life expectancy. But now, looking back, the vortex engine in the united states and the west may also be a data falsification with exaggerated content。
In fact, life expectancy was not the most important issue for our air force at that time, but rather that the core parts of al-31f remained in russian hands, which limited the amount of production of the 20 base fund. Moreover, this engine does not fit well with the 20th, but it does. After loading the russian engine, the 20th does not have its aerodynamic advantage, and many movements are afraid to do it when flying。
Later, flying began to improve the base of 20, with a small volume of self-researched vortex 10b, an engine that uses the second generation of single-crystal vortex blades produced in our country, which, unlike russian-made engines, dated back to the 1980s. It can be said that the engine is an old machine that was briefly assembled on 20 after the 2018 model, but was not satisfied with it by the air force and served as a replacement for al-31f。
The engine was then upgraded and the vortex 10c began to be heavily assembled and decimated by 20, which was much optimized with the addition of a sawn-tooth cavity sprayer, which could effectively contain infra-red radiation in the tail. The full-authority digital control system, the upgrading of turbine blades to high-temperature monocrystal materials, the overall structure is lighter in quantitative terms and fuel economy is better than the vortex 10b. The thrust was 14. 5 tons and increased considerably without the launch of the intensive cruise, with a push of 8. 5 to 8. 8, which was far greater than the russian-made al-31f. The equipment vortex 10c speeds up by 20, climbs are fully enhanced, and the altitude can sustain a long ultrasonic sprint。
But it can't be called 20a, waiting for an engine that belongs to itself, which is turbo 15. Once this paragraph is out, the 20-year-old will be successful。
The vortex 15 small-intensity, heavy-push flight has brought to the fore the air engine of the chinese warplanes to the top of the world, with 11 tons of non-extractive single-stage thrust. This is a terrible number, and two engines are fully capable of flattening 20 to achieve ultrasonic cruises, and the speed has increased considerably. The single booster was 18. 5 tons, and fuel consumption was reduced. The third generation of single-leaf blades are used to give it a longer life than the previous ones. It is only from the 15 columns of the vortex that 20a, or even double-seat 20s, that it actually becomes combat power。
In addition to waiting for the engine, it has been optimising 20%. Many have found that 20-a is thicker than the original, and that part of it rises, with the specialized term “supersonic drum pack” and some military experts also call it the “back-to-back crops”. At hypersonic speed, the early 20-year-old model produces a violent wave in the back neck and additional resistance. With this drum bag, the cross-sonic barrier was cut down and the extra space in it added a tank. There is less resistance and more fuel belts, so 20a is further away。
Z20a has also made extensive use of argon nitrogen radar and has been upgraded in receiving and sending components。
On the whole, the aircraft is in every way going beyond the united states f22, and as for f35, its combined strength is not as high as 35 in our country, and it may not yet have an f22, let alone 20a。
What does it mean to cut off the basic 20s
This means that this type of aircraft has matured, and it has been 15 years since its first flight, and that the base model may be accompanying the chinese air force for the next 15 years. By 2039, the f-20, like the 10th, would have become the background plate for 36 and 50 smokes。
Veterans don't die, they just fade away. In any case, it means a great deal to the chinese air force. The emergence of deck 10 shows china's ability to design and produce advanced fighter jets on its ownAviation industryIt's even a small lead. The first flight of the two six-generation planes was the complete dumping of backward hats across the pacific。
Now some practical western military experts are still watching the 20a service, because they know that the greatest pressure now on the u. S. Air force is this plane, not only to press them at an advanced level, but also in sufficient numbers, as far as the six-generation plane is concerned, it is only for the next 10 years。
