高速直升机方案研究

对目前三种主流高速直升机——复合式、倾转旋翼／机翼式和转换式进行了综合分析；根据发展态势，比较了它们的构型、性能及关键技术等方面的优缺点，并对可行性进行了讨论。在此基础上．提出了一种旋翼／机翼转换式高速直升机方案，并对此方案进行了旋翼系统的原理性试验，对关键技术——模式转换过程进行了理论计算和试验研究。验证了直升机模式和飞机模式在相互转化过程中升力、功率和操纵的平滑连续性及保持操稳性；最后，根据研究结果，经过计算得出了此方案的总体参数。

Research on the Scheme of a High-Speed Helicopter

In this paper,the Scheme of a High-Speed Helicopter is designed basded on the research on the existing schemes and the key technique .Their advantages and shortcomings were discussed. The key point of this scheme is the shift smoothness of lift, power and control between the helicopter mode and the airplane mode. Besides calculation of transfer process, experiments were carried out to verify the feasibility of the scheme. The lift and power were measured for different wind speed, rev, and angles of attack of the diskwing/rotor. Using the calculation method that was revised by the experiment, the foundamental parameters of the scheme are defined.
