Cannon Muzzle Blast Noise Suppression Facility

Abstract

This report describes the theoretical and analytical investigation of a stationary noise suppressor for cannons. (1) A water table model was used to establish the basic suppressor configuration. Shock wave and lumped parameter mathematical models were used to analyze suppressor performance. A model 20mm suppressor was constructed, tested, and found to compare favorably with test results. A full scale suppressor (for 155mm gun) was designed on the basis of analysis and model tests; a simplified version was constructed and field tested. The simplified full scale suppressor successfully reduced the noise levels to acceptable values.
