直升机桨—涡干扰试验研究

The Experiment Stude of Helicopter Blade-Vortex Interaction

本文简要介绍了桨涡干扰试验研究中的桨叶表面压力测量、旋翼噪声测量、LLS和PIV技术,BVI情况下桨叶表面压力和旋翼噪声的特点,并以Berend G,van der Wall等采用的方法为例介绍了PIV试验数据的处理技术。

This paper briefs the blade surface pressures and rotor noise measured techniques,LLS and PIV techniques,and the characteristic of blade surface pressures and rotor noise in BVI conditions. Describs the Analysis methodology of PIV data used by Berend G. van der Wall etc..
