Vincent Tanguay. Parametric study on the interior ballistics of 105 and 155 mm artillery guns / Параметрические исследования внутренней баллистики 105 и 155 мм артиллерийских орудий
Technical Memorandum DRDC Valcartier TM 2007-350. 2008, - 62 p.
The interior ballistics code IBHVG2 was used to calculate the muzzle velocity and peak acceleration of projectiles ranging in mass from 10 to 50 kg. The simulations were performed with both 105 and 155 mm guns. These were the C3 and LG1 (105 mm) and the M777 (155 mm). For comparison purposes, extended length 52-calibre LGI and 52-calibre M777 were also considered. Three propellants were investigated: the triple base M31, and two composite propellants, JA2 and the developmental propellant LCT. For every gun-propellant-projectile combination, the propelling charge mass arid grain geometry (web) were optimized. The web was optimized to match the maximum breech pressure of the gun, while the charge mass was optimized according to two different criteria: projectile travel at burn-out and peak muzzle velocity. The results provide a good overview of the performance of conventional artillery systems.
