推力矢量是指飞机将其推力从它的发动机平行方向引向其它方向的技术。推力矢量技术除了可以提供垂直起降或短距起降能力外，还能在空战中为飞机提供额外的机动力。 推力矢量一般用可以转动的矢量喷嘴或者扰流片来实现。

Thrust vectoring, also thrust vector control or TVC, is the ability of an aircraft, rocket, or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) in order to control the attitude or angular velocity of the vehicle.
