Abstract

This paper shows the effect of the side clearance on the air-intake performance of a ramjet for the High Mach Integrated Control Experiment (HIMICO). As the result of the wind tunnel test, the mass capture ratio (MCR) of the original intake is 15-35% lower than the designed value. CFD analysis suggested that this is caused by the flow separation on the ramp surface due to flow leakage from a 1-mm side clearance located at the moving part. The mechanism of the side clearance effect is cleared by CFD, and the CFD results considering the side clearance almost agree with the experiment. Then, a new intake in which the side clearance is reduced to 0.25 mm was designed and tested. The maximum MCR of the new intake is increased approximately 14% compared to the original intake.
