摘要

本文介绍了叶片在转子盘平面上周期性脉动运动的转子概念。结果表明，非定常驱动引起的气动现象对旋翼推力和效率都有提高作用，其影响程度与驱动频率有关。特别是，气动性能的提高与大尺度前缘涡的发展有关。结果表明，最优频率与涡的形成时间有关。

Rotor performance enhancement through blade surging

This short paper introduces a new concept of rotor where the blades undergo a periodic surging motion in the rotor disk plane. It is shown that the unsteady actuation induces aerodynamic phenomenon that can enhance both rotor thrust and efficiency, depending on the amplitude and frequency of actuation. In particular, the increase in aerodynamic performance is found to correlate with the development of a large scale leading edge vortex. Accordingly, the optimal frequency is found to correlate with the formation time of this vortex.
