| 摘 要： | 试验研究了外挂干扰引起的阻力系数的变化，特别是外挂吊挂方式、外挂位置变化引起的阻力变化以及多外挂间的干扰系数。初步研究表明外挂吊挂方式以半埋式产生的阻力系数增量最小，外挂位置以外挂处在逆压梯度大或顺压梯度较小的流场中和外挂处符合面积率分布要求为佳。外挂间的干扰系数随外挂的组合方式和全机布局的变化而变化，十分复杂。

| Abstract: | In this paper,investigations are conducted with experiments in wind tunnels for the Changes of drag Coefficient on the store induced by interference between aircraft and stores,especially interference of store suspension forms,store positions and multiple stores.Primary investigation results show that the drag of half buried store is minimum,and it is the best to put the store in the adverse pressure or in small pressure gradient flow field and the ditribution of sectional area should be in agreement with the area role.The interference is very complex and changed with the store combinations and aircraft configuration variations. |
