Using the thrust force vector technology to the new design and on themodification next century military airplane, indeed is an effectivetechnical breach, it to the fighter aircraft stealth, reduces anti-,reduces weight extremely is all effective. The thrust force vector technology can let the motor power a part turnthe control force, replaces or partially replaces the control surface,thus greatly reduced the radar return area; No matter the angle ofattack big and the flying speed is much low, the airplane all may usethis part of control force to carry on the operation, this increasedthe airplane controllability. Because directly has the control force, and size and directioninstable, also increased the airplane agility, thus may suitablyreduce or remove the vertical stabilizer, also can substitute othersome control surfaces. This to reduces the airplane to be possible the survey to beadvantageous, also can cause the airplane the resistance to reduce,the structure reduces again. Therefore, the use thrust force vectortechnology solves the design contradictory best choice. Has permittedfor many years, country and so on America, Russia has performed themassive performance flight, had proven using the thrust force vectortechnology indeed can achieve prearranges goal. After in April, 1991 the Gulf War ended, the Pentagon puts out 50billion US dollars, the deve
