MUZZLE BLAST MEASUREMENTS ON HOWITZER, 105MM, XM103E1

Abstract

Measurements of muzzle-blast in the crew area of the 105mm Howitzer, XM103, without a muzzle brake and with muzzle brakes WTV-F8241 (High Efficiency) , 5/K (Medium Efficiency), and WTV-D8259 (Low Efficiency), were made to determine the peak overpressures produced. The overpressures produced by the four different brake conditions were one of the most important factors determining which brake would be used on the XM102 Howitzer. The howitzer was fired at elevations of 2, 45, and 62 - 68 degrees. It is recommended that the 5/K (Medium Efficiency) Brake is the maximum efficiency brake to be considered for this weapon. The Watertown Blast Shield provided for this program is not recommended for this weapon. It is recommended that wearing V51R earplugs should be mandatory for all personnel located in the crew area when the 105mm Howitzer, XM102, is fired.
