Research on the optimization design of integrated scramjet/airframe

Yinli Xiao

Abstract

A performance calculation program and an optimization design platform of integrated scramjet/airframe,including three main parts:forebody/inlet,combustor and nozzle/afterbody,were developed in this paper.The hydrogen-fueled,integrated scramjet/airframe configuration optimization design was performed based on the optimization design platform.The integrated scramjet/airframe two-dimensional configuration of optimized design was numerically simulated.The calculation results indicate that the performance calculation program of integrated scramjet/airframe is exact and the optimized design result is reliable.
