BRL's 50mm High Pressure Powder Gun for Terminal Ballistic Testing - The First Year's Experience

reportActive / Technical Report | Accession Number: ADA123861 | Open PDF

Abstract:

The first years operational experience in the BRL Hypervelocity Range is reported here. A 50mm bore by 120 caliber travel smooth bore high pressure powder gun fires into a radiographic terminal ballistic range through an evacuated blast tank. Fifty-eight shots were fired in 1981, permitting establishment of baseline interior ballistic performance data on in-bore masses from 100 to 635 grams, propelling charge masses from 400 to 1000 grams, and breech pressures to 650 MPa, with 20mm ball powder and a custom 35mm M30 propellant. Velocities up to 2645 ms were achieved.
