Brothers, let's talk about the J-20 this time, since the J-20 was replaced with the new WS15 flight launch, it has been a long time since I said it. But recently J-20's improved WS15 spout picture suddenly appeared, then I have to say, after all, this should be the final model of J-20, after so many years, the heart of the big problem Hangfa has finally been cured, replaced with WS-15 is also considered to have reached the design level of the year, of course, this time not only to see the nozzle, by the way, but also to see the overall appearance of the cockpit after repair, the line is smooth, and the aerodynamic level will be improved a lot.
Here's the thing, recently foreign social media released relevant pictures of the J-20 improved model, you can see the fuselage number "205X", which is also the latest batch of J-20 with WS-15. In fact, the relevant pictures have appeared in 2023, but at that time, for some reasons that everyone knows, the tail spout was Marseille, and now it should be time to see the tail spout clearly.
Judging from the pictures, the WS-15 of the new J-20 still has some content, and the spout is completely pure black, which is very different from the nozzle of the third aunt of the AL-31 when I saw WS-10C in the past. The obvious metallic color of the general engine nozzle is completely missing, and instead the WS-15 is all black, which feels more like some unknown coating on the convergence sheet.
This coating may be for models that reduce radar reflections, or for tail heat sources. If you look at the current data, the WS-15 can achieve an afterburner thrust of 161865-181373N, a thrust-to-weight ratio of 9.7-10.87, and an air flow of 138kg/s, which is 17.7 tons more than the F119 engine used in the F22. In addition, it features a full-authority digital electronic control system (FADEC) that enables precise control of engine thrust and vectoring. Of course, the picture of this tail vent is still relatively blurry, and I look forward to a new picture later, which can speculate some characteristics of the WS-15 used by the J-20.
In addition, it can be seen that this complete version of the J-20 has been trimmed in the nose part, the rear of the cockpit all the way to the skin of the engine, and the overall appearance feels smoother. Generally speaking, this visual feeling of beauty is in line with the principle of aerodynamics, which is why most advanced fighters are pleasing to the eye and handsome in appearance. The modification of the J-20 this time is also because after the new aviation engine, the overall thrust has changed too much, especially the size of the WS-15 has become larger, so that the engine compartment section will be convex, which also causes the line of the cockpit back cover to the tail to fluctuate too much. After correction and adjustment, the details have been perfected, and the aerodynamic level of the J-20 model can be said to have reached its peak.
If the J-20 is J-20A after being reequipped with WS-10C, then now it can afford the J-20B, and Chengfei can really rest assured that the production of J-20 is bold and open, after all, it is already a complete body. And a new J-20 production line that happened to be Chengfei was also completed, not to say that it was full horsepower, but it was also to accelerate production. It is no wonder that Aquilino, the commander of the U.S. Indo-Pacific Forces, recently shouted in Congress that the annual output of the J-20 will soon exceed 100 aircraft, and air superiority will soon be achieved.
In fact, is the annual output of the J-20 really only more than 100 planes now? I am afraid that it is the complete version of the WS-15 of the J-20, with an annual output of more than 100 planes, and this is what makes the West feel the most sad. After all, whether in terms of quantity or performance, the J-20 has become a fifth-generation aircraft that surpasses the F22, not to mention that the F22 has also been retired. The J-20 is now seeking defeat alone, trying to find an opponent, but the F22 is already dying. I have to say that the era of adults has changed, and the era of trying to interfere with others at will with absolute superiority in one or two weapons and equipment is gone forever.
In general, after the WS-15 of the J-20B was refitted, the supersonic cruise capability did not run, and it was finally considered a complete version, but the development of the J-20 still has a long way to go. The previous J-20S two-seat version, as well as the unmanned wingman and manned UAV integrated command system worn, the difficulty and complexity of these things are completely more than the WS-15 flight launch, which is also the most needed part of the future J-20 from reaching the Western level to surpassing the Western level to form a new quality of combat effectiveness.
