Abstract

Calculation methods and experimental results are presented for the performance of a 40-mm light gas model launcher using a mixture of helium, hydrogen and oxygen. The effect of charging pressure on peake pressure in the chamber is given and compared to closed chamber combusiton. Heat lossess from the chamber were measured during cooling in the closed chamber firings. The effect of incomplete combustion were estimated. Performance of the launcher is summarized as muzzle velocity as a function of maximum chamber pressure for various projectile weights. The velocity of a 40-gram (a cylindrical slug of minimum practical weight) projectile would be 14,000 ft/sec at the maximum chamber design pressure of 60,000 psi.
