摘要
本文介绍了在2米级旋翼动态地效试验装置上进行的动态地效试验研究工作,包括试验系统的准备、试验内容和结果处理。研究的状态主要包括模拟舰面升沉和滚转运动两个方面,对不同高度下不同的升沉幅值、不同滚转角度幅值均进行了讨论,给出了分析结论。
This article presented the experiment study of dynamic hovering ground effect the helicopter rotor with the 2m rotor test rig.The procedure from test preparation to data process is included.The dynamic aerodynamic load responses to the pitching and rolling motion of a moving ground-plate is investigated within the study,various rotor height and pitching amplitude or rolling angle are applied in the test configration.According to the test result comes out a primary analysis and conclusion.
