Well-known be in since entering millennium, Chinese spaceflight respect builds ability it may be said is to having the progress like the rocket this is whole world be obvious to all, annihilate 15, annihilate 20, annihilate 31, carry the 20 affiliation that wait for a plane made China successful stride inside club of world top air man, china also is except the United States the 2nd has the state of machine of two the Five Dynasties at the same time.
The message says China has had tremendous breakthrough on engine development, the eddy fan that Chinese proper motion develops is about to equip on 15 engine horses army, this also is indicating China requested the dependence to Russian-made engine, eddy fan - 15 it is above function also should compare foregoing where to have huge promotion.
The engine that we know to we are developed by oneself before cannot satisfy the use of my army plane at all, the biggest question is motivation does not live, later annihilate the 20 AL-31 motor that Russia cannot not use first after enlisting in army.
At present annihilate 20 having beginninging mass-produced annihilate 20, nowadays has 3 product line, can produce 2-3 every months on average to wear a plane, can produce more than near 40 plane one year, this also is meant should prepare 80 corresponding engine the least.
2012 when our country bought 160 AL-31 engine to Russia, ahead a batch annihilate this kind of 20 engine that equip namely, the opportunity for combat that foreword enlists in army after instead is homebred engine, this to Russia loss a thousands of client of 100 million.
Use " Chinese core " annihilate - 20 it is the eddy fan that everybody expects all the time - 10 engine, be in 16 years early when, come out annihilate 20 equip preparation this homebred engine, arrived just as one would expect in those days type of solicit comments of intermediary of official of second half of the year announces annihilate external this engine of 20 equipment is too improve all right model.
For the WS10 engine that takes China, passed all sorts of changing ten this years recently advanced its thrust increases from 12 original tons 15 stewed, engine life also achieved 4000 hours.
And the eddy fan of nowadays 15 engine just are to suit annihilate most the engine of 20, also can saying is to be annihilate 20 special and custom-built, brand-new concealed body design was used on the appearance, among them what pneumatic distribution side uses is tooth form structure, airframe material used the special data that can absorb radar wave, this is OK also better settlement annihilate 20 in area of catoptric of the place in radar.
