埋入式进气道的设计及其气动性能研究
An Investigation on Design and Performancefor a Submerged Air Intake
【摘要】 本文提出了一种埋入式进气道的气动S弯设计方法,设计了进气道模型;并研究了该进气道在高、低速以及存在侧滑和正、负迎角时的性能。研究结果表明设计的埋入式进气道的总压恢复达到了使用可接受的程度,且进气道的性能随迎角的增加而改善。当存在负迎角和侧滑角时该进气道的性能变化也不太显著,这说明进气道具有较宽的工作范围。
【Abstract】 A new method for designing a submerged air intake is given in this paper.With this method a model of an intake is desgined and tested at different Mach numbers,incidences and yaws.The results show that the total pressure revovery of the air intake is desirable.It is also shown that the performances of the intake are improved with the increase of incidence,and deteriorated slightly at the negative incidence and large yaw.This indicates that the submerged air intake designed can be used widely.
