Projectile Balloting Attributable to Gun Tube Curvature
WebAn investigation of balloting of projectiles launched from a two-stage light-gas gun Award Information Agency: Department of Defense Branch: Air Force Contract: N/A Agency Tracking Number: 19824 Amount: $61,474.00 Phase: Phase I Program: SBIR Solicitation Topic Code: N/A Solicitation Number: N/A Timeline Solicitation Year: N/A Award Year: 1993 WebThis paper is based upon the observation that, when a bullet is fired, it creates characteristic markings on the cartridge case and projectile. From these markings, over 30 different features can be distinguished, which, in combination, produce a "fingerprint" for a firearm. By analyzing features within such a set of firearm fingerprints, it ... showings of top gun maverick
Uses of Balloting Analyses During Projectile …
WebIn-bore projectile responses at various locations of the projectile while traveling through the simulated gun tubes were obtained. The balloting was evaluated in both time and … WebNov 16, 2024 · In-bore balloting can be caused by any one or more of the following conditions: projectile center of gravity and principal axis offset from the bore centerline; projectiles, as manufactured, are not perfectly concentric; projectile/gun tube clearances may exist at projectile surfaces; insufficient stiffness of the projectile/gun tube interface ... WebWhen the projectile exits the tube, balloting affects the muzzle crossing velocity of the ammunition and hence influences initial conditions of the flight phase of the projectile [4]. Thus a high degree of balloting decreases the accuracy and increases dispersion on … showings.com
