| Abstract: |
The process of muzzle exhaust following the shot of a light gas gun of 24-mm caliber at velocities of up to 8 km/s is investigated. Developments of muzzle exhaust and muzzle shock wave and their interaction with projectile and measurement facility are studied numerical-experimentally. Computer visualization of the process is presented using numerical modeling. The experimental data including direct as well as shadow (in passing light on a semitransparent diffusing-surface base plate) photography registration of conical shock wave head are in good agreement with numeral results and computational visualization of phases of the muzzle exhaust. Parameters of air lock along its length at passing the projectile against muzzle cross section have been obtained. Dependencies of working gas (hydrogen) parameters versus time at the muzzle cross-section illustrate the basic stages of the process such as the change in air lock size and the moment of appearance of the projectile in a zone of reliable registration. The high-quality forecasting of the stages of the process defines the safe and optimal location of measurement facility in the light-gas gun experiments that allows one to considerable reduce risks and cost of the expensive natural experiments demanding a long time preparation. |
