A Subsonic Gas Gun for Pneumatic Projection of Gun Propellant Grains.
Abstract
A locally constructed gas gun is described which can reproducibly project grains of M30 and NACO propellant at velocities varying from 50 to 90 m/s for M30 propellant and 100 to 135 m/s for NACO propellant. Grains can be fired over the temperature range of +50 degrees to -40 degrees C. Both M30 and NACO grains become increasingly prone towards brittle fracture as the projection velocity increases and the temperature decreases. A comparison of Australian produced BS NACO D propellant made from wood cellulose and American produced NACO SPCF propellant made from cotton cellulose suggests the latter has a greater tendency for brittle fracture under the conditions employed in this study.
