涵道式推力矢量螺旋桨 技术是推力矢量技术在传统直升机上的推广和应用，以替代直升机原有的尾桨系统。这一系统不仅能产生传统直升机尾桨的扭矩，还能产生前推力。在直升机上加装升力机翼，起对旋翼卸载的作用，将构成一种符合低全寿命成本，高性能要求的新概念复合式直升机
Dredging-type thrust vectorial propeller technology is the promotion and application of thrust vectoring technology in traditional helicopters to replace the helicopter’s original tail rotor system. This system not only produces the torque of a conventional helicopter tail rotor, but also produces a forward thrust. The addition of a lift wing to a helicopter that acts as a rotor unloader will result in a new concept compound helicopter that meets the requirements of low full life and high performance
