| 摘 要： | 本文通过悬停状态地面效应对旋翼和机身气动特性影响的研究,探索它们之间内在机理,为旋翼性能、操纵性和稳定性提供悬停试验及分析结果。通过对试验与理论计算结果的分析,给出了模型旋翼在悬停状态下,旋翼气动特性随地面高度变化的现象,利用实测桨叶表面压力的方法进一步验证地效情况下旋翼功率随拉力变化的规律。

| Abstract: | This article describe about the research of aerodynamic characteristic of rotor and fuse- lage in hovering ground-effect.The research is focused on its inner philosophy,to provide hovering -test results and analysis results for rotor's performance,manipulation,stability.By the experiment and theoretical analysis,we have found out how aerodynamic aracteristic of rotor vary with the height of the ground under the condition of hovering state for a model rotor,we test the results by pressure testingand illustrate how power vary with lift. |
