摘　　要：从下洗角的改变对导弹升力性质的影响着手,通过理论推导与分析,研究了飞行高度对导弹地效应的影响机理。以战斧导弹为研究对象,选取导弹飞行高度作为控制变量,采用数值模拟的方法,计算不同飞行高度下导弹受地效作用的升阻力变化情况,在此基础上定性总结飞行高度对导弹地效作用的影响规律,给出了升力和阻力分别受地效应影响的理论公式并验证其影响机理。Starting with the influence of downwash angle on lift characteristic of missiles,the influence mechanism of flight height on WIG of missiles is analyzed by derivation of equation and theory analysis.By taking Tomahawk as research subject and selecting flight height as controlling parameter,the lift and drag changes caused by WIG with different flight height is calculated by numerical simulation. The influence rule of flight height on WIG of missiles is summarized qualitatively,and the theoretical formula that how WIG influenced lift and drag is given,also the influence mechanism is verified based on the study.
