用文中描述的尾流分析方法研究了螺旋尖涡的运动。
The analytical method for predicting the hovering rotor wake is described to investigate the motion of the helical tip vortex.
首先应用自由尾流分析技术来计算旋翼尾迹和发动机绕排流空间的洗流速度。
First, free wake analysis was carried out to calculate the rotor wake geometry and the downwash around the engine jet space.
旋翼尾流的作用通过自由尾流分析来求解局部的诱导下洗速度以修正翼型攻角。
Rotor wake effects are modeled in the form of a correction applied to the angle of attack along the blades. This correction is obtained by computing the local induced downwash with free wake analysis.
