Abstract

To enhance the starting ability was one of the most serious issues in air propulsion system. In the present work, an adaptive slot control method was proposed to expand the working range of hypersonic inlets to a lower Mach number with weak losses, which was beneficial for engineering applications. Simulation results indicated that the starting Mach number can be decreased from 3.2 to 3.0 with five parallel slots at a width of 4mm. The flow inside the slot channel was self-driven due to the pressure gradient across of the separation shock. In case that the inlet was restart, the slot channel flow would be strongly suppressed.
