A parametric study of muzzle blast
Abstract
The muzzle flow properties of a 20mm cannon are measured for a range of launch velocities from 260 m/s through 1000 m/s. Sequential spark shadowgraphs are taken of the flowfield development. Pressure surveys are made in the blast ranging in distance from 0.2 m to 0.8 m from the muzzle. An idealized muzzle device is placed in the flow and surface pressure determined. Experimental results are compared with available theory.
