ABSTRACT:
A device for the limitation of gas pressure in a projectile having an outer shell by the production of a control stream comprises a combustion chamber disposed inside the projectile; the combustion chamber having a combustion chamber lid; control lines connected to be changed by gas from the combustion chamber for transferring the gas pressure from the combustion chamber; monostable fluidic elements being arranged in the control lines in a region of the combustion chamber lid for assisting in confining the control stream; branching lines disposed in the lid and connected with the monostable fluidic elements, the branching lines including vent openings in the outer shell for releasing gas to the atmosphere and an overpressure element for permitting gas to be expelled from the combustion chamber when an overpressure exists therein, whereby gas expelled via the overpressure element assists in the production of the control stream.
