wake velocity

Moreover, the effect on thrust and propulsive efficiency is considered for reduced frequency, non-dimensional heaving amplitude, pitching amplitude, phase difference between heaving and pitching motion, wake velocity profile, and the extent of wake rollup.

讨论了约化频率、无因次升沉运动幅度、俯仰运动幅度、升沉和俯仰运动的相位差、尾流时均速度剖面、尾涡卷起程度对振动翼推力和推进效率的影响。

The ATB tilt-rotor and the 5/ 6-scaled V-22 tilt-rotor were used as numerical examples and the free wake and induced velocity were calculated for hover flight. In order to validate the present method, the comparisons between calculations and available experimental data have been performed.

分别以ATB旋翼和缩比的V22旋翼为算例，计算了悬停状态的旋翼自由尾迹和诱导速度，并与可得到的试验数据进行了对比，验证了该方法的有效性。
