Experimental study on Combustion modes and thrust performance of a staged-combustor of the scramjet with dual-strut

Résumé

To enable the scramjet operate in a wider flight Mach number, a staged-combustor with dual-strut is introduced to holdmoreheat release at low flight Mach conditions. The behavior of mode transition was examined using a direct-connect model scramjet experiment along with pressure measurements. The typical operating modes of the staged-combustor are analyzed. Fuel injection scheme has a significant effect on the combustor operating modes, particularly for the supersonic combustion mode. Thrust performances of the combustor with different combustion modes and fuel distributions are reported in this paper. The first-staged strut injection has a better engine performance in the operation of subsonic combustion mode. On the contrast, the second-staged strut injection has a better engine performance in the operation of supersonic combustion mode.
