摘要

采用自由尾迹算法和涡格法

编制了针对复合式直升机旋翼-机翼升力系统的气动计算程序

对于旋翼和机翼间的气动干扰情况进行了初步分析

计算了不同前飞速度下机翼旋翼之间的相互干扰情况

计算结果验证了程序的可行性.同时表明:机翼-旋翼间的干扰与速度有较大关系

而机翼对旋翼扭矩的影响大于对旋翼拉力的影响.由于相互干扰的存在

旋翼和机翼的效率都会降低.这为复合式直升机的设计提供了参考和分析工具.

Abstract

The compound helicopter has gained more and more attention so far since there is an efficient way to improve the performance of such helicopter.By employing the free-wake arithmetic and vortex lattice method(VLM)

a program for the rotor-wing system of compound helicopter aerodynamic computation has been developed.With this program

interactions between the rotor and the wing in different advance ratios were computed.Some conclusions can be made from the computation results: for the compound helicopter described in the paper

the influence of wing on the rotor lift is small

but a little bigger on the rotor torque;with the increase of the flight speed

the influence of rotor on the wing decreases;and the interaction reduces the efficiency of both the rotor and the wing.
