Abstract : A performance analysis of the UTIAS Implosion-Driven Hypervelocity Launcher is presented which is based on a numerical code using the artificial viscosity technique. The numerical calculations are inviscid as no losses are taken into account and the analytical results yield performances that are at least 50 percent greater than the available experimental data. From the results obtained numerically, detailed wave-diagrams of the processes in the launcher are given. The launching conditions at the base of the projectile are emphasized. An optimization study of the existing launcher (8 in. dia.) hemispherical implosion chamber and several barrel sizes was also made followed by an analysis of what should be the optimum parameters of a second generation launcher that is able to launch one-inch diameter projectiles to hypervelocities. In order to make this calculation more realistic, a number of points should be studied and these are outlined in the conclusions. (Author)
