【摘要】 复合式自转旋翼机是一种新型的旋翼机翼复合式飞行器。本文主要研究的是复合式自转旋翼机在总体设计中的若干关键参数选择方法。基于儒柯夫斯基涡流理论,提出一种在高速平飞状态下的旋翼拉力特性分析方法,与实验结果基本一致:根据复合式自转旋翼机的特殊外形,参考飞机设计和直升机设计的总体设计分析方法,提出适合复合式自转旋翼机总体设计中动力选择、重量分析、尾翼设计、旋翼设计的参数选择方法,分析某设计指标下的复合式转旋翼机动力参数、重量参数、尾翼参数以及旋翼参数的选择,为复合式自转旋翼机的关键参数选择方法提供了一思路。更多还原

【Abstract】 Composite autogiro is a kind of aircraft which combines rotor and wing.This paper mainly studies about several critical parameter choice methods of conceptual design of composite autogiro.According to Zhukovsky vortex theory,a method of rotor tension characteristic analysis on high speed flying condition is also proposed and analyses the relevance among rotation rate,collective pitch angle and tension.The results show general consistency which are compared with experience results.Considering the unique configuration of composite autogiro and referring to the method of aircraft design and helicopter design,this paper puts forward an analytical approach of power choice,weight analysis,tail design and rotor design,which fits to design composite autogiro configuration,and analyses concretely power,weight and rotor parameters of a composite autogiro on some design orders.It provides a thread to design critical parameter choice method of composite autogiro.更多还原
