摘要
本文介绍了一副研制型旋翼模型在CARDC 8m×6m低速风沿的试验概况,给出了两种桨尖形状旋翼模型试验的悬停效率、前飞需用功率、变距拉杆载荷、桨叶载荷及振动特性的对比结果。并对结果进行分析,得出不同桨尖形状对旋翼一些特性的贡献。
This paper summarized a rotor model test for research in CARDE 8m x 6m low speed wina tunnel,and gave the comparison test results of rotor model with two kinds of tip shape of blade.Through analyaing the results of aerodynamic efficiency in hovering required power in forward flight pitch link loads blade loads and dynamic loads,we gained the contribution made by different tip shape of blade to some performance of rotor.
