摘　　要：在牵引空投试飞过程中,牵引力是非常重要的参数,如果选择不合适就可能会有较大的安全隐患。然而,对于试飞时牵引力的测试,还没有一个较好的方法。本文通过对空投时空投物在舱内运动画面的研究,提出了一种新的牵引力计算方法,并通过该方法对某次牵引空投试验的牵引力进行了计算。计算结果表明,该方法可以正确计算牵引力。Traction force is a very important parameter during the traction airdrop test flight.If it is not selected properly,there may be great safety risks.But there is no good method for traction force test during flight test.In this paper,a new traction force calculation method is proposed by studying the motion picture of airdrops in the cabin during airdrop,and then the traction force of a traction airdrop test is calculated by this method.The calculation results show this method can correctly calculate the traction force.
