Concept and Feasibility Studies of Muzzle Brake Blast Suppression Devices for 105mm and 155mm Howitzers

摘要

Results of the following studies are presented: analytical determination of overpressure maps resulting from firing Howitzers with muzzle blast suppression devices; analyses for evaluating the effects of design parameters comprising the device; techniques for computing the dimensionless pressure and mass rate of discharge - dimensionless time histories in the suppression device; the effect of time which the projectile remains in the suppression device; design parameters of the device which create attenuated overpressures in the crew area; a proposed design for the 105mm Howitzer blast suppression device and the stress analysis of the design; an analytical study relating to the directional effects of blast waves.
