摘　　要：由于直接采用全尺寸舰载机进行全自动着舰试验的风险较高,可以采用缩比模型模拟全尺寸飞机进行着舰的试验方案。基于相似系统原理,研究了缩比模型模拟全尺寸飞机着舰的相似关系,具体包括着舰导引律、自动驾驶仪、进近动力补偿系统与甲板运动补偿系统的增益以及航母运动与机舰相对运动参数的相似比例关系。以某算例舰载机及其缩比模型为算例,完成了各自着舰的数学仿真计算。结果表明,全尺寸飞机着舰数学仿真结果与缩比模型仿真结果满足运动相似关系,且各项参数的相似比例与推导结果一致,证明了本文研究结论的正确性。Considering the high risk of automatic carrier landing test,a scheme to simulate the automatic carrier landing process of a full-size aircraft with its scaled-model is proposed.To realize this scheme,the similarity relations of automatic landing processes between full-size aircraft and scaled-model are deduced based on the similarity theory,including the similarity relations of automatic landing control law parameters,the similarity of carrier motion parameters,and the similarity of aircraft-carrier relative motion parameters.At last,applying the mathematical simulation models of a carrier-based early warning airplane and its scaled-model,their automatic landing processes are calculated,and the results show high similarity between their automatic landing processes in accordance with the analysis,proving that the similarities deduced in this paper are correct.
