桨叶

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.

采用伽辽金权数有限元素法发展了一种悬停状态下无铰旋翼桨叶气弹稳定性的分析方法。

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.

基于桨叶二阶升力线理论和旋翼自尾迹模型，本文在第三章建立了一个适合于直升机旋翼尾迹结构及桨-涡干扰气动特性分析的方法和模型。
