摘要: 复合式直升机受到了越来越多的关注,但其分析手段还较少.结合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分析.计算了不同前飞速度下机翼位置对旋翼-机翼气动干扰的影响.从计算结果可以发现,在高速情况下,除旋翼扭矩外,气动干扰对机翼位置不敏感;低速时的干扰情况较复杂,还需要进一步研究;在旋翼不对称涡系下,机翼升力不对称,会产生滚转力矩.这对复合式直升机的设计能起到一定的指导作用.

Abstract: The compound helicopter has gained more and more attentions so far, but the analysis method available is limited. Employing the free-wake arithmetic and vortex lattice method(VLM), a program for compound helicopter aerodynamic computation was developed. Using this program, interactions between the rotor and the wing were computed in different advance ratios and wing locations. From the computation results, some conclusions can be made: for the compound helicopter described, the interaction between the wing and the rotor isn-t sensitive to the wing location in high velocity, except the rotor torque; In low flight speed, the interaction is more complex, and needs more researches; Because of the dissymmetrical structure of the rotor wakes, the spanwise lift distribution of the wing is dissymmetrical, and it will cause a rolling torque.
