Analysis and Design of a Two-Stage Hybrid Launcher

Abstract

This report summarizes the analysis and design of a two-stage hybrid launcher capable of soft launching 12-pound, 4-inch diameter models to 20000 fps. The design and configuration of explosive drivers to inject high energy hydrogen into the compressor section of a two-stage gun is described. The calculation of ballistic performance is of note. The detailed calculation of inviscid, adiabatic core flow in conjunction with an analysis of launch tube boundary layer growth is used to evaluate heat transfer to the launcher walls. An analysis and design of tungsten and composite thermal liners is presented. (Author)
