ABSTRACT:
A device in a launch unit for a mortar projectile (4), where the launch unit (6) has a propellant charge (10) capable of generating propellant gas for launching the projectile from the barrel (1) of the mortar, the launch unit being designed to be placed in a loading position behind the projectile. The launch unit has an enlarged cross surface (20a) in the barrel against the pressure from the propellant gas, the enlarged cross surface creating an expulsion force on the launch unit. The cross surface is in the form of wing elements (20a) arranged crosswise in the front portion of the launch unit (6) and being bendable in proportion to the magnitude of the propellant gas pressure in order to accomplish a self-regulation of the expulsion velocity of the launch unit.
