摘要 介绍了某机挂副油箱时,在着陆过程中,某一局部迎角范围稳定度较低时,采用改变着陆余油进而改变重心的试飞方法。在试飞中,从稳定度较高的状态,逐步飞到稳定度较低的状态,取得了满意的试飞结果。文中还给出了风洞实验和飞行试验的相关性以及飞行员对飞行品质的评估。 This paper introduces a flight test method for an airplane with externalfuel tanks,the airplane has the low static stability margin at some angles of attack dur-ing landing. In flight test landing residual fuel was varied to control the locations ofC. G. from forward to afterward gradually-from the higher static stabilities to the lowerones. The flight test results were satisfied.In the paper the correlations of the wind tun-nel results with flight test restults,and pilot’s evaluation to the flying qualities are pre-sented.
