AbstractJapan Aerospace Exploration Agency (JAXA) has been investigating scramjet engines in Kakuda Space Center using Ram Jet Engine Test Facility (RJTF) et al. The engine tested at the flight condition of Mach 6 in RJTF showed very important characteristics depending on internal geometry. CFD has been carried out to solve the inner air flow, and some concepts for the design method have been found by the authors. This time, mass flux (density times velocity) distributions in the engine inner flow is calculated for two engine configurations. One is an engine configuration with rectangular-tailed strut which showed the good performance in the engine test at RJTF, and the other one is a virtual engine configuration with boat-tail strut which will be an improved configuration of the former. CFD results showed that the mass flux distribution is better than that of configuration with rectangular-tailed strut. Discussion on the better fuel distribution is described based on the result of mass flux distributions in the two engine configurations in this paper.
