摘　　要：阵风载荷是飞机强度设计中需要考虑的重要载荷来源。以飞翼布局飞机FW-11作为研究对象,采用"1-cosine"调谐阵风模型,求解飞机阵风响应下的运动方程,计算并分析飞机在垂直离散阵风响应下的载荷特性,并将其与常规布局的参考飞机进行对比。结果表明,定常平飞时FW-11飞机承受较小的载荷,但阵风引起的载荷增量较大。Gust load is one of the key loads that should be considered for aircraft strength design. FW-11, which is an aircraft with flying wing configuration, is the object of study. ＂1 - cosine＂ tuned gust model is applied to solve the equation of motion in gust of FW-11, the loading characteristics meeting vertical discrete gust is calculated and analyzed, the results are compared with the conventional baseline aircraft, showing that FW-11 bears lower loads in steady level flight condition, but higher gust induced load increment when encounters gust.
