1.A theory of aeroelastic stability of hingeless rotor blade in hover by using the Galerkin weighted residual finite element method is developed in this paper.

采用伽辽金加权余数有限元素法发展了一种悬停状态下无铰旋气弹稳定性的分析方法。

2.In Chapter 3, based upon the blade second-order lifting-line model and rotor free-wake model, an analytical method is developed for predicting the rotor wake structure and BVI airload.

基于二阶升力线理论和旋自尾迹模型，本文在第三章建立了一个适合于直升机旋尾迹-涡干扰气动特性分析的方法和模型。
