| Abstract: | Considering the effects of flight state and environment characteristics, this article dedicates to the internal pressure prediction of the hypersonic vehicle. The passive and active internal pressure control methods of hypersonic vehicle are summarized. By combining the quasi-one-dimensional isentropic flow method with computational fluid dynamics (CFD) numerical simulation, the effects of passive air inflation/deflation system on the internal pressure are studied. These results have considerable significance for the design of the air inflation/deflation system of the hypersonic vehicle. |
