Long-tail type rifle grenade

Abstract

The invention relates to a rifle grenade which can increase the initial speed and the range by one time, has quite simple structure and is provided with a slender rod (a grenade tail) which is connected with a fighting part, provided with a sealing device at the tail end and used as a part for simultaneously bearing the powder gas thrust and providing flight stability.

Description

technical field [0001] The present invention relates to a new structure and propulsion method of rifle grenade. Background technique [0002] Rifle grenade is a kind of super-caliber ammunition launched by gun and blank bullet or bullet (relative to blank bullet, hereinafter referred to as live ammunition). The general structure of existing rifle grenade is to connect a hollow tailpipe behind the warhead, and the tailpipe end has bullet wings. When firing, the tailpipe fits into a launch rod that is usually integral to the front end of the barrel. When using a blank shell to launch, the gas generated by the combustion of the propellant (hereinafter referred to as gunpowder gas) directly rushes into the tail pipe to push the grenade. Bullet catcher should also be set in the tail pipe of the rifle grenade that uses live ammunition to launch. After the live ammunition warhead leaves the gun chamber, it enters the bomb capture device and is captured by it, and transmits a sma...

Problems solved by technology

[0006] Aiming at the deficiencies of the existing gun grenade, which can only mainly use the expansion energy in the later stage of the expansion of the gunpowder gas, the energy utilization rate is low, the muzzle velocity is small, and the volume is large, the present invention provides a new structure of the gun grenade, so that the gun grenade can burn from burning It can be propelled by the propellant gas from the initial stage, thus greatly improving the utilization rate of propellant energy, and greatly increasing the muzzle velocity and range
