Half a month has passed since the war between Russia and Ukraine, and the Russian army has begun to shift the military targets of air raids from various Ukrainian military facilities to the entire Ukrainian defense industry, and began to destroy various Ukrainian military enterprises in the form of air strikes one by one. Many of them have quite a relationship with China, such as the Russian army has not yet begun to launch actions against them, we Chinese old acquaintance Madasic factory and so on.
Some media on the other side even inexplicably stood up and said that the Russian Air and Space Force's act of blowing up Ukrainian military enterprises is creating trouble for our military, such as the Madasic factory that may have been destroyed in the List by the Russian Army, which is likely to cause difficulties in the supply of engines for main battle aircraft such as PLA fighters and put the Air Force in a difficult situation.
We still don't know how this factory with only production capacity and no design ability is crucial to the mainland aviation industry, nor can we understand why a factory with only large culverts for transport aircraft, small thrust turbofans for trainers and turboshafts for helicopters can cut off the supply of fighter engine parts.
Simply speaking of advanced fighter engines, CCTV has just come out in the news channel in the past two days to officially announce the new generation of small culverts on the mainland than the large thrust afterburner turbofan engine turbofan-15, and the design target of the turbofan-15, codename Emei and the progress of many tests are clearly described, and it is probably the first time that the turbofan-15 has obtained such a degree of publicity.
CCTV this video sounds carefully, it belongs to everything said, but nothing is said about a kind of nonsense literature, at most it is to make the things that have become public news before through the official tone of the public again, the code name of the turbofan-15 Emei is known to everyone, in the orderly advancement, is the standard power of the new generation of heavy fighters on the mainland This is nothing to say, the only one that is somewhat valuable, that is, it has been carried out many times of experiments This stage of progress.
According to CCTV, turbofan-15 has undergone multiple rounds of testing, and the indicators have also been improved and improved; first of all, this multi-round is naturally indicative of the prototype assembly of turbofan-15 has been completed for a long time, and the test work has been carried out for a long time, it is clear that the light test bench test can not be called multi-wheel test, the high-altitude platform and the flight table test has also been carried out a lot, which can be called multi-wheel test, from another point of view, it is also a proof of the previous legend, Turbofan-15 has been equipped with a J-20 prototype, launched a single-engine matching test flight, and after the completion of all the matching test flights, it can also announce the completion of the design finalization and begin to organize trial production.
It should be said that this progress is still very objective, although the origin of the turbofan-15' High push pre-research ' opened very early, but it is very late to get on the right track, the middle has also experienced the twists and turns of technical program adjustments and so on, if the turbofan-15 can really maintain the current rapid catch-up progress, then the mainland's aviation industry may also be able to form a rare catch-up, of course, not the Americans, but we have long studied and long-term purchase of finished products of the Russians, the Russians gave their Su-57 to develop the product 30 engine has been installed T-50 prototype as early as a few years ago to develop a machine matching test flight, but for unknown reasons, until now the test flight progress is relatively slow The original plan for service around 2024 has also been delayed until 2026 to complete the test flight, according to this time node, as long as the turbofan-15 is a little harder, rush to put into mass production before the product 30, it should not be much of a problem.
Although the overall route selection of the product 30 is slightly aggressive and ahead of the turbofan-15 (the turbofan-15 adopts a very conservative 3-level fan + 6-6-1-1 layout of the 6-level compressor, and the product 30 is 3-5-1-1), but overall the performance of both sides is at the same generation level, the Russians have been launched several years in advance, and the project that gathers the greatest ability and technical reserves can finally be caught up by us, and it can only be said that a penny is difficult to defeat the hero, or that there is money to smash the technology is really can do whatever it wants. If we can make the product 30 up early in the morning to catch up with the late set, then we can indeed say that in the broad sense of aero engine, we have a new sub-field, which has run to the past master and embarked on the real kingdom of freedom.
Of course, many people must say that before comprehensively surpassing the United States, no matter who is ahead, or more concerned about what improvements the performance of the J-20 will be brought by the new engine, whether the supersonic cruise capability can be unlocked after the new engine, whether the maneuverability can be further improved, and so on. Supersonic cruise this thing, more than the engine to look at the aerodynamic design, as long as the supersonic lift-to-drag ratio is done high enough, the engine is almost able to supersonic cruise, J-20 itself is a supersonic aerodynamic optimization to do a very good typical, even the earliest version is still using AL-31FM1 can also supersonic cruise, replaced by the new engine mainly brought, or the further improvement of the thrust-to-weight ratio to bring about the optimization of energy characteristics and because of the better energy characteristics to bring about the improvement of mobility On the other hand, the new engine's higher fuel efficiency further improves the J-20's already considerable internal fuel range.
With a new engine, the J-20 is also one step closer to the full state, the two-seat version of the J-20 can rely on the optimization of the new engine to recover a lot of the original maneuverability and range sacrificed in order to add a seat, while one more person to enhance multi-faceted combat effectiveness, but also to maintain flight performance at a very good level; at the same time, the new engine also brings more sufficient power supply capabilities, can support more on-board electronic equipment, whether it is the integration of intelligent skin in the aircraft to increase a large number of situational awareness capabilities, Or to improve the performance of electronic warfare or other kinds of hardware that require a lot of power supply, it is very necessary, with the new engine to lay the foundation, the performance of the J-20 can go further.
