doi:10.12382/bgxb.2024.0245

Abstract

Abstract:

Recoilless launch can reduce recoil effectively,but it causes the reduction in low muzzle velocity.To resolve the conflict between muzzle velocity and recoil force,a reverse jet recoilless scheme based on combustible cartridge and electromagnetic induction ignition is proposed.Energy is transmitted to the ignition head through electromagnetic induction,which ignites the fast-burning propellant and combustible cartridge in the chamber to provide the launch energy.After reaching a certain level of pressure,the Laval nozzle is opened,and gas is sprayed backwards to balance the forward impulse of projectile.For high muzzle velocity recoilless launch,the loading density and chamber pressure are high,and the interior ballistics is prone to instability.To increase the stability of interior ballistics,a classic interior ballistic model during the shooting process is established,The performance of interior ballistics is analyzed and the stability of interior trajectory is studied through numerical simulation.The ballistic test research was conducted to verify the proposed scheme.The results show that the proposed scheme.can be used to reduce the recoil impulse to below 1.5N·s without reducing the muzzle velocity of projectile.The scheme can provide new ideas for the future development of light weapons.

Key words: recoilless gun, interior ballistics, electromagnetic induction ignition, combustible cartridge case
