DESIGN OF LIGHT-GAS MODEL LAUNCHERS FOR HYPERVELOCITY RESEARCH

Abstract

The parameters which influence the operating capabilities of two- stage, light-gas guns are discussed. Calculations are presented which illustrate the relationships of these parameters under idealized conditions, and empirical correlations derived from firings in several launchers are used to provide the necessary correction factors to adjust the idealized treatment. The construction techniques used in the design of light-piston-type, two-stage, hypervelocity launchers are discussed. This includes the mechanical design of development-size equipment and larger equipment for use in an aerodynamic test facility. Design features discussed include: (1) powder-helium or powder- hydrogen piston propulsion, (2) pump-t be, gas-heating system, (3) high pressure equipment design, and (4) maintenance equipment required for efficient operation.
