缩比模型模拟全尺寸飞机自动着舰的相似关系

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.
