International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.Inlet unstart prediction and warning are strictly crucial to the operation of hypersonic engines, especially for combined cycle engines where implementation across a wide speed range poses significant challenges. This paper proposes a realization method that involves constructing the conditions of critical backpressure ratios for the inlet unstart and ...

Influence of Geometric Parameters on Intake Performance of 3D Ramp‐Type Scramjet Inlet
International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.The methods based on the assumption of inviscid flow are typically used for the initial design of the scramjet inlet geometry, but the presence of a viscous boundary layer can degrade the validity of the results and lead to nonoptimal operation. This study explored the design space of three‐dimensional ramp‐type scramjet inlet geometry and investigated

Scramjets and shock tunnels—The Queensland experience [PDF]
Progress in Aerospace Sciences, 2005 This article reports on the use of a shock tunnel to study the operation of scramjet powered configurations at sub-orbital velocities above 2 km/s. Thrust, as given by a net thrust equation, is used as a figure of merit throughout the study. After a short description of the shock tunnel used and its operating characteristics, experiments on the ...

Investigation of Flow Control for the Hypersonic Inlets via Counter Flow
International Journal of Aerospace Engineering, 2015 Experimental results show that there exist two flow fields in the hypersonic inlets when the forebody waves interact with the lip boundary, which is similar to the shock reflection ion hysteresis phenomenon.
