Dynamic Characteristics of a Recoil System When Firing Projectiles with Mach 4.4 Muzzle Velocity from a 105 mm Cannon
This paper discusses the dynamic characteristics of a recoil system when firing armour-piercing fin-stabilized discarding sabot projectiles. They are fired with a muzzle velocity of Mach 4.4 from a 105 mm caliber cannon either equipped with a multi-perforated muzzle brake (MPMB) or with a bare muzzle. In the recoil system, the MPMB moderates the recoil velocity and prolongs the time of resistance to the propellant gases’ force, thereby reducing the inner pressure of the cradle, which possesses both functions of the recoil cylinder and the elevating center, and attenuating the recoil force on the trunnions. The reasons for the formation of each of the dynamic characteristics are discussed. All measurements in this study can be a significant reference for developing guns, tanks, or the chassis of fighting vehicles.
