Feasibility of a Hybrid Hypervelocity Launcher

This report documents an investigation of the feasibility of a hybrid hypervelocity launcher. Included are evaluations of: (1) the thermodynamic performance of the working medium, (2) the ballistic cycles necessary to achieve the desired projectile muzzle velocities, (3) possible loss mechanisms which can degrade ballistic performance, and (4) material response to predicted heat loads.
