AbstractJapan Aerospace Exploration Agency has been investigating scramjet engines in Kakuda Space Center using RamJet Engine Test Facility (RJTF) et al. The engine tested at the flight condition of Mach 6 showed very steep fuel distribution. The fuel injected from the vertical injector on the side wall stays near the side wall and the top wall along the engine. The steep fuel distribution is an obstacle for the engine performance completion. In order to solve the problem, the authors are focusing the influence of cowl shock wave on the fuel distribution. In the result of simulation by visualizing the stream lines in CFD, the effective stream lines are found useful for the fuel spreading. In this paper the authors describe results of trial combustion in two engine configurations including the improved configuration.
