| 摘 要： | 本文论述等环量线尾迹描述方法,并介绍旋翼尾迹涡系的等环量线处理技术,及其在固定涡系下的实施导致的一种求解前飞旋翼气动载荷、流场与性能的方法。对H34机三种情况计算表明了对经典尾迹结果的改进,并证明尾迹结构精细化对新一代尾迹分析方法是必不可少的。

| Abstract: | A now wake modeling technology using circulation contours is described for helicopter rotors. This technology is able to tackle with complex time varying spanwise circulation distribution, and apt to be transplanted into advanced distorted wake analysis to represent complicated rotor wake structure reasonably and delicately. Application has been made for helicopter rotors in forward flight with a rigid wake. Correlation with H-34 helicopter rotor airloads shows remarkable improvements and neccessity for rotor wake modeling refinement as well as wake distortion. |
