Abstract
The turbine-based combined cycle (TBCC) scramjet operates at a wide range of speeds, from subsonic to hypersonic. However, the effective inlet area is reduced due to factors such as adverse pressure gradient, boundary layer separation, and shockwave-boundary layer interaction. The effective inlet area decreases, leading to a decrease in suction and compression performance. As a result, a turbine engine may experience a stall or inlet unstart. This study performed a 3-dimensional computational analysis for each mode of the dual-path scramjet according to Mach number, altitude, and bleed flow control. The effective inlet area decreased due to an increase in altitude and a decrease in Mach number. The choking at the inlet was effectively suppressed because bleed flow control delays the flow separation.
