AbstractMany efforts have been made to improve performance of scramjets (1-4). For this purpose cavities and struts were frequently used as the functions of mixing enhancement and flame stabilization. The present work focused on the effects of different strut and cavities on the thrust and drag of a side-wall compression scramjet model. This model consisting of a side-wall compression inlet, a combustor and a thrust nozzle and fueled by kerosene was tested in a propulsion tunnel that typically provides the testing flow with Mach number of 5.8, total temperature of 1800K, total pressure of 4.5MPa and mass flow rate of 4kg/s(5). A strut was used to increase the contraction ratio and to inject fuels, as well as a mixing enhancement device. Several wall cavities were also employed for flame-holder. The experimental results show that the cavities do not produce significant drag, but improve thrust performance well. It is found that the strut functions as an isolator and also helps the mixing enhancement, resulting in the improvement of the thrust performance. However the strut causes big drag to the scramjet model. Copyright © 2005 by the American Institute of Aeronautics and Astronautics Inc. All rights reserved.
