METHOD FOR FIRE OF GUIDED MISSILE FROM RECOILLES GUN AND RECOILLESS GUN FOR ITS REALIZATION Russian patent published in 2007 - IPC F41F3/42 

FIELD: missile launchers.

SUBSTANCE: the method consists in the fact that a high-frequency impact load on the body of the high-pressure chamber and the powder charge is produced before the ignition of the powder charge. After the ignition the process of burning of the powder charge is accompanied with re-plenishment by high-temperature pyrotechnical gases with a warming-up and turbulizing action of them on the flow of gases elapsing from the high-pressure chamber. The high-pressure chamber in the recoilless gun is provided with a tapered prechamber n the rear nozzle unit accommodating the burning follower, and the electric primer in the central nipple. A damper cavity is formed under the electric primer, it is connected to the prechamber through a hole oriented to the bearing surface of the prechamber and the rear multi-nozzle grid. The throttle ports of the prechamber are oriented at an acute angle to the axis of the rear nozzles. The rear and front multi-nozzle grids are made with intersecting ducts for passage of gases in projection to each other.

EFFECT: enhanced muzzle velocity of the missile in the temperature range of combat employment.
