Abstract
Scramjets are a promising hypersonic airbreathing technology for economical access-to-space and atmospheric transport. Reliable scramjet inlet starting is of crucial importance for successful scramjet operation. It is shown that unsteady flow, resulting from the rupture of a diaphragm, can result in a steady started inlet flow. Time-accurate computations illustrate flow and wave motion during the unsteady starting process. The effects of viscosity and diaphragm mass on the inlet flowfields are investigated by time-accurate computational simulations.
