Abstract
- In this paper, based on the fixed hypersonic inlet with rectangular section, a new concept of variable geometry hypersonic inlet that the tip can turn and move back off to increase the mass capture ratio is presented, and operating in a large Mach number range from 4 to 6.5. The flow in the hypersonic inlet was analyzed with numerical analyzer, and the inlet performance comparisons were made between the variable geometry hypersonic inlet and fixed inlet at different Mach number of inflow. The results indicated that the performance of the variable geometry inlet as much as fixed one under design Mach number, and the performance of the variable geometry inlet was better than fixed inlet under non design point. All of that indicate that the variable geometry hypersonic inlet was satisfying. [ABSTRACT FROM AUTHOR]
