摘要
研究一种关于小型飞行器的新型升力和推力系统——轮翼的气动特性。通过自行设计并搭建的基于虚拟仪器的实验平台,进行地面试验,试验主要研究了轮翼转速对系统气动特性的影响。结果表明:随着轮翼转速的增加,系统提供的升力及推力增大。由于轮翼系统消耗的能量绝大部分用来产生升力及推力,因此轮翼系统具有较高的工作效率,为进一步研制小型无人直升机探索新型动力模式。
This paper is about an aerodynamic experiment of a new concept lift and thrust system-wheel-wing.An experimental platform based on virtual instrument（VI） is established,and the ground experiments are done.The rotating speed of the wheel-wing is considered in this experiment and the influence on the aerodynamic characteristics of the system was mainly researched.The results of the experiment show that this system appeared high aerodynamic efficiency and the lift and thrust increased as the rotational speed of the wheel-wing increased.This will provide new concept power basis for the advanced research on the small unmanned helicopter.
