地效飞行器动力增升系统安装位置的实验研究

Experimental Study on Mount Position of Power Augmented Ram of Wing-in-ground Vehicle

本文通过模型实验研究了动力增升系统的安装位置对典型地效飞行器静态推力恢复和静态升力的影响,进而研究了改变动力增升系统的安装位置后,飞行器起飞距离、起飞速度和升力系数的变化,并探讨了主翼端板对上述实验结果的影响。实验结果证明,设计合理的动力增升系统能够在保持地效飞行器纵向稳定性的同时能有效改善起飞性能。

This paper studied how the mount position of power augmented ram affected the static thrust recovery and static lift of a typical wing-in-ground vehicle through model experiments.In addition,it studied the change of the take-off distance,take-off speed and lift coefficient after the reposition of the power augmented ram,and the influence of the end plate mounted on the above result of the experiments was explored.The results of the experiments showed that a proper designed power augmented ram could effectively improve the take-off performance of a wing-in-ground vehicle while keeping its longitude stability.
