一种新型组合机翼/旋翼系统

介绍了一种新型组合机翼/旋翼系统—卸载升力偏移旋翼（ULOR）的原理。这种组合旋翼系统能够增大直升机最大飞行速度,提高前飞效率,使直升机具有更大的机动性,同时可以克服升力偏移旋翼的主要障碍,即减小振动。ULOR系统将机翼与升力偏移旋翼结合在一起,有效消除了后行桨叶的失速,并使旋翼效率提高了一倍。这种系统可以显著提高单旋翼带尾桨直升机以及纵列式旋翼直升机的最大速度和航程。最后,提出了一种ULOR与辅助推进系统组合的新构型设想。

A New Combined Wing-Rotor System

A new combined wing/rotor system—unloading lift offset rotor（ULOR） concept was de-scribed.Through this combined rotor system,the maximum flight speed would be increased,the for-ward flight efficiency would be improved,and the greater maneuverability would also be delivered while the primary barrier of lift offset rotors would be avoided,mean the vibrations would be re-duced.The wing was combined with rotor by ULOR system to effectively eliminate retreating blade stall and double rotor efficiency.The system nets significant increased in maximum speed and range for single main rotor and tandem rotor helicopters.Last,a new configuration combined ULIR with auxiliary propulsion was suggested.
