FIELD: defense industry; grenade launchers unitary cartridges.

SUBSTANCE: the invention is pertinent to the field of unitary cartridges, in particular, to the shells and cases of the submachine gun grenade launchers and automatic grenade launchers. A shell and a case for the grenade launchers contain a combat part fixed in the case and supplied with a primer-igniter. The combat part body with preset potential its crushing out into splinters from inside is equipped with a riffled grid and has the combustion chamber filled in with a powder propellant charge, that are separated by a horizontal diaphragm mantled with a bellow. The combustion chamber is made in the form of a container fixed on the body and having a shape of a truncated cone, the smaller base of which is combined with the partition. At that the container is mounted inside the case with the coaxial radial clearance connected through the radial grooves of the diaphragm with the receiver, where the primer-igniter is located. The radial grooves of the diaphragm are adjoining to its central hole. Between the of the body of the battle part and the powder propellant charge a sealing gasket is located. Use of the invention ensures an increase of functional reliability of the general purpose shells and cases for the grenade launchers and a range of fire at drop of costs of manufacture of structural elements and assembly works.

EFFECT: the invention ensures an increase of functional reliability of the general purpose shells and cases for the grenade launchers and a range of fire at drop of costs of manufacture of structural elements and assembly works.
