The influences of the molecular weight and total temperature of a primary gas on the flow fields of constant-area mixing tubes for ejector-jets were investigated. First, in order to investigate the exit choke, parametric studies were carried out for

A new variable termed the ejector drive parameter was proposed as a dominant parameter of the pressure recovery ratio of constant-area mixing tubes. It was derived from the one-dimensional analysis of a zero-secondary flow mode. This parameter repres

Flow fields in the constant-area mixing tubes of ejector jets were investigated under the starting-limit conditions of an aerodynamic choking mode by performing numerical simulations and cold flow experiments. Pressure recovery was almost completed i

Breakdown of diffuser flow was often observed in our scramjet engine tests. This facility operation may damage the engine wind-tunnel and should be prevented. An one-dimensional analysis was applied to the diffuser flow to identify the causes of the

A simple variable Mach number nozzle for aerodynamic engine tests was designed and calibrated. In this new nozzle, only one hydraulic actuator made freestream Mach number change from 2 to 4 during a run of the wind tunnel. The optimization of the noz

A method to evaluate aerodynamic performances of scramjet engines by using multi-probe rakes was proposed. The aerodynamic tests were carried out under Mach 4 flight conditions. The Pitot and static pressures were measured at 250 points in the cross
