This means it can hover like a helicopter, but when flying forward can reduce the speed of the main rotor because the wings provide part of the lift.
这意味着它能像一架直升机那样作空中悬停，而在向前飞行时，又能降低主旋翼的速度，因为它的一对短翼提供了部分升力。
This means it can hover like a helicopter, but when flying forwards can reduce the speed of the main rotor and let the wings provide part of the lift.
这意味着它能像直升机一样悬停，但向前飞时可能减少主旋翼的速度并让这两个短翼提供部分提升力。
It is powered by two jet-turbine engines which operate both the five-bladed main rotor and, through a gearbox and shafts, a pair of propellers on two short wings.
它由两个喷气涡轮引擎提供动力，以驱动五个叶片的主旋翼，以及通过齿轮箱和连轴驱动在两边短翼上的一对螺旋桨。
