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。
In this paper, a pneumatic S-bend design method of buried inlet is proposed, and the inlet model is designed. The performance of the inlet at high and low speed, and the existence of side slip and positive and negative angles of attack are studied. The results show that the total pressure recovery of the designed in-port inlet reaches the acceptable level of use, and the performance of the inlet port improves with the increase of the angle of attack. When there is a negative angle of attack and side slip angle of the inlet performance changes are not too significant, indicating that the inlet has a wide range of work.
