| 摘 要： | 为了提高直升机的飞行速度,出现了用涵道风扇矢量推力系统取代常规的尾桨和尾翼的复合式高速直升机.然而,涵道风扇矢量推进系统各部件间相互作用很复杂,从理论上确定涵道风扇矢量推进系统的气动特性尚有相当难度,为了研究涵道风扇矢量推进系统气动特性,利用涵道风扇矢量推进系统试验模型,通过试验实测该系统在轴流状态的气动力及舵面偏角和设计参数对系统气动力的影响,得到了一些涵道风扇矢量推进系统所特有的气动现象,其结果可作为理论建模的依据.

| Abstract: | In order to increase helicopter maximum flight speed,compound helicopters with Vectored Thrust Ducted Propeller(VTDP) instead of conventional tail rotor are proposed.Due to the complexity of the interaction among components of the VTDP,the theory of the VTDP is far from complete.The purpose of this paper is to measure the static aerodynamic forces of a Vectored Thrust Ducted Propeller.A test model is developed and the aerodynamic forces and moments as well as the influences of design parameters on them are ... |
