Get rid of foreign restrictions, another engine brings good news, H-20 is ready to fly!

Public figures in the vertical military field, dynamic analysis of military intelligence, profound insights into the political situation, historical war cases, blood and iron loyalty of families and nations, revealing the performance of military equipment, and the contention of hundreds of schools. We have always stood at the front line of military observation. Here we can see turbulent winds and clouds, as well as flames and blazes. Here, look at the military spirit, military feelings; here, I will protect the security of my family and country with you!

In the past decade, China's aviation equipment has developed rapidly. In addition to the bomber -20 strategic bomber being manufactured, there are also fighter -20 fighters, cloud-20 large transport aircraft and straight -20 helicopters, which belong to the "20 series" military aircraft. At present, many people are most concerned about when the last version of the 20 series will be released, and the author has said the same thing many times: if this huge new 20 is used for strategic deterrence, it will soon appear; and if it is to be used He came to command the actual combat, so I'm afraid that when his opponent was bombed into the sky, he didn't know what it would look like. In the past, I preferred the first possibility, but now I don't think so. However, there is no need to doubt the existence of the project itself, and the progress may exceed most people's expectations, so continue to wait patiently. During the waiting period, it is also possible to analyze each of these 20 subsystems: for example, in the overall frame design of a 200-ton aircraft, one party has completed more than a decade of breakthroughs. If the structure itself is not a problem, the aerodynamic design and flight control of the flying wing fuselage is not a problem, because this type of drone has been flying everywhere. Some people's version, natural software and hardware are no problem; as for various advanced invisible skins and highly intelligent sensor systems, one party has taken the lead in the world. The only question that really needs attention is the first flight and what kind of engine will be used for the first flight. Some people say it uses the same three-generation non-enhanced long-endurance version as the B2. The thrust of the B2 single engine is about 8.5 tons, the total thrust of the four engines is about 34 tons, and the B2 with a thrust-to-weight ratio of 0.2 is 170 tons. To be honest, this weight-to-weight ratio is a bit too low. After all, most of the modern passenger jets have a thrust-to-weight ratio of 0. 25 or more. However, B2 pursues long voyages and subsonic speeds. This weight-to-weight ratio is still sufficient. But to one side, the US Air Force does not have as many bases around the world. At present and in the next 10 years, the number of strategic tankers is not as large as that of the US military. Therefore, in order to reach the minimum threshold for strategic bombers, they must also pursue more than 200 tons of airframes and carry more fuel and weapons. Only in this way can a direct flight to the third island chain have practical value. If we also use the third-generation non-afterburner engines in the first flight and the first batch of engines, we will obviously face the dual problems of insufficient thrust-to-weight ratio and insufficient actual verification of engine performance. For a brand new strategic model and high aerodynamic flying wing type, a newly developed afterburner is used for the first flight. This possibility is very low. Also, without any hassle or hassle, this model has begun to develop. Therefore, it is more likely to use off-the-shelf engines for the first flight and the first batch of equipment. Now the new twin-engine H6 series and quad-engine Y20 series actually use the D-30KP-2 engine, or imitate the improved WS18 engine. D-30KP-2 is a turbofan engine with a small bypass ratio. The maximum diameter of the fan is only 1.5m, which is not much larger than the diameter of the third-generation non-thrust afterburner fan, and the maximum installation diameter is about 1.8m. Therefore, for a large 20 with a very large actual body thickness, there is enough space for the entrance And exports doubled. If four sets are used at one time, the original total thrust can reach 50 tons, which is 47% greater than the stable thrust of B2. If calculated according to the 170-ton B2, the theoretical maximum take-off weight of this type 20 giant flying wing can reach 249 tons, which is almost close to the maximum take-off weight of the current 160-ton aircraft of 260 tons and a strike radius of 12,000 kilometers. Even if the size is further reduced, a take-off weight of 220 tons and a direct return radius of 10,000 kilometers can be guaranteed. The D-30 series engine has good thrust-to-weight ratio and reliability. Just because of the 1970s design, fuel consumption was higher because the bypass ratio was too small. However, the relatively small diameter of the embedded engines of both bombers is an advantage. Advanced advanced technologies such as high-pressure turbine single crystal blades, annular combustion chambers, FADEC systems, high-performance aero engine bearings, and high-pressure turbine powder discs have been widely used in aero engines Therefore, for a large 20 with a very large actual body thickness, there is enough room to double the inlet and outlet.

Some people do not believe that the domestic version can improve so much than the original version! In fact, it is not surprising to think that a refurbished engine was used for the first flight of a certain 20 fighters. Only refurbished blades doubled the original life. With the complete modernization of the overall materials and technology, there is a self-made engine with a thrust of more than 13 tons. A large number of batches of WS18 went offline, which solved the power problem of at least six large military aircraft in one step, including large flying wing 20. At this stage, it can ensure a substantial increase in the number of equipment that can be used in war and no longer under human control.
