| Abstract: | A performance calculation program and the optimization design platform of full-flowpath scramjet were set up,including the three main parts of forebody/inlet, eombustor and nozzle/afterbody. Aiming at hydrogen fueled, the full-flowpath scramjet configuration optimization design was performed based on the optimization design platform. The results indicated that the performance of variable-geometry combustor scramjet is improved. |
