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 tap 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. Being based on the aerodynamic effect of strut found by authors, the strut fuel injection is proposed to improve the fuel distribution. In the result of simulation by visualizing the steam lines in CFD, it is found that the strut fuel injection might be able to spread the fuel in the engine cross section much more than the side wall injection.
