Radial Turbine Preliminary Aerodynamic Design Optimization for Expander Cycle Liquid Rocket Engine

Abstract

A response surface-based dual-objective design optimization was conducted in the preliminary design of a compact radial turbine for an expander cycle rocket engine. The optimization objective was to increase the efficiency of the turbine while maintaining low turbine weight. Polynomial response surface approximations were used as surrogates, and the… (More)
