propulsive efficiency

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 faster a jet plane goes the greater its propulsive efficiency.

喷气式飞机的速度越快,它们的推进效率就越高.

The results show that swimming with fingers holding together provides higher propulsive efficiency than swimming with fingers splaying at various angles of attack.

结果表明，在各个攻角状态下，手并拢划水均能获得更高的推进效率。

This jet has a very high propulsive efficiency.
