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 aircraf

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

5、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 sta

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 c
