摘要
通过4种入口形式的进气道低速特性的典型试验结果,对不同入口形式的进气道低速特性及影响因素进行了分析。结果表明:小迎角下,头部式进气道能提供高的总压恢复系数和低的畸变指数,但对迎角变化较敏感;遮蔽式进气道的综合性能较好,有利于提高飞机在大迎角下的机动性能;它们分别适用于不同布局的飞机。
By the test results of four type of inlets at low speed, the properties of inlets and its influence factors are analyzed. The results show that nose inlet could provide high total pressure recovery coefficient and low distortion coefficient at small angles of attack, but sensitive to angle of attack. Composite properties of obscure inlet are preferable so that it is advantageous to improve the maneuverability of aircraft at high angle of attack. These four forms are fit to different configuration of aircraft respectively.
