Revive the battleplan of 57 the Five Dynasties that are Russia development, everybody is small meritorious service to its impression very Oh, maneuverability is very pretty good, often exhibit in boat on person of flying sell one's own things' dazzling movement, can says outside astral UFO, but concealed body performance is more average, have fatal flaw even, more archetypal than if machine can see engine lamina actually from the front.
According to public data, revive the openly RCS value of 57 is as high as 0.51889 square metre, and the classical makes F117A front RCS of concealed body opportunity for combat has 0.0305288 only, the RCS of certain angle is worth obverse side of plane of test and verify of technology of body of concealed of 7II of our country annihilate about 0.1 square metre. That is to say, below certain condition, revive the openly RCS value of 57 compares certain and special 2 generation even machine is even expensive. Why to meet such?
Everybody knows, body of contemporary radar concealed is academic above all genetic Russian Wu Fei not cuts a husband, although black poors,the concealed body theory that not cuts a husband is used the earliest at the design of F117 opportunity for combat by the United States, but long-term since, the Russian also developed much research to radar concealed body, force is not actually weak. However the succeeds classic a specific example of a battle nearly 20 years ago, the concealed body opportunity for combat that lets Russia however designs complete go astray.
On March 27, 1999 night, a F117A " goatsucker " invisible when attack plane is finishing bomb task to return to base, by south missile of 3 air defence hits allied Sam, prang, this was broken invisible the myth with invincible opportunity for combat, and the development that regards Sam as missile of 3 air defence square, the 3 view of Russia also by this thing refresh, the missile technology that their one party confronts him and radar technology are exceeding and self-confident, on the other hand, suspect effect of technology of American concealed body makes a holiday. The Russian thinks even, since connect Sam this kinds 3 old old air defence missile can down F117, so is missile of air defence of more advanced S300, S400 also does can relaxed down have the F22 of concealed body ability and F35 likewise?
This logic looks flawless, very reasonable, more crucial is, the academician of academy of system of Russia country aviation expends Duosuofu, with respect to hold this sees the logic that seems rigor. And he, just about revive the most important pushing of train of thought of design of 57 opportunity for combat hand, below his influence, revive 57 from at the beginning, pay attention to maneuverability and supersonic speed cruise, and put concealed body performance in end, this also was brought about today revive the fixed position of 57 such awkwardness.
What have to say is, our country Shenyang flies in the design " snow Zuo " opportunity for combat when, also drew lessons from revive the train of thought of 57, weigh motor-driven and light concealed body, brought about it to use the position of unique 3 alas side in machine of the Five Dynasties, pneumatic overall arrangement is very complex. However complex pneumatic overall arrangement not only destroyed " snow Zuo " concealed body function, and brought more complex flight control, and just of Shen Fei respect exists on flight control tremendous weak sports, also do not have at the same time revive the powerful engine of 57 can offer an alternative, such since " snow Zuo " opportunity for combat connects full measure even ligneous prototype was not made come out, with respect to die.
And annihilate 20 begin from one design, resemble F22 same, turn concealed body function and intelligence put in the first place, pay attention to the motor-driven function of the plane at the same time, especially function of supersonic speed motor-driven, the engine that if thrust of transhipment of through cargo is bigger,comes, can realize long supersonic speed cruise. because such, 20 ability walked out of annihilate with revive 57 and " snow Zuo " different successful way, become F22 and F35 most the adversary of dread.
