Flameholding characteristics and flame behaviors of a scramjet model combustor with two-stage fuel injection for low flight Mach numbers

Journal of Thermal Science and Technology
In this study, two types of fuel injection methods were applied to a scramjet model combustor equipped with a dual-cavity flameholder and a burned-gas injection to achieve operation at a low flight speed corresponding to a flight Mach number of ...

An experimental investigation of a thermal compression scramjet with OH imaging

, 2015
Scramjet engines must be designed to operate over a range of Mach numbers. In order to maintain robust starting characteristics at low freestream Mach numbers, the inlet contraction ratio must be minimized, reducing performance at high Mach numbers.
