rotating-blade propeller

The unsteady Loading noise generated by interaction of a front rotor wake with an aft rotor in a counter-rotating ( CR) propeller is analyzed and the noise radiation formulae are derived.

本文着重研究了反旋桨扇前排转子尾流与后排转子干涉形成的非定常负荷噪声，并与试验结果作了对比。

So, how studies can accurately prediction to the contra-rotating propeller hydrodynamic performance is more important.

所以, 研究如何更能准确地预报对转螺旋桨水动力性能更为重要.
