Cooling device for cooling combustion gases from recoilless anti-tank weapons

摘要

The present invention relates to a cooling device (2) for cooling combustion gases from a rocket motor (1) in an antitank weapon. The cooling device (2) comprises a coolant reservoir (3, 21) containing a coolant (4). The coolant reservoir (3, 21) is arranged such that the coolant (4) is transferred from the coolant reservoir (3, 21) to the combustion gases in the gas outlets (6) of the rocket motor (1) in response to a pressure increase in the rocket motor (1). The coolant reservoir (3, 21) constitutes an integral part of the rocket motor (1) and is connected to the combustion chamber (7) by at least two gas inlets (8) for pressurization of the coolant (4). The coolant reservoir is furthermore connected to the rocket motor nozzle (9) by at least two coolant outlets (10) for transfer of coolant (4) from the coolant reservoir (3, 21) to the rocket motor nozzle (9).

主权项

1. A cooling device for cooling combustion gases for lowering sound pressures from a rocket motor in an anti-tank weapon, which cooling device comprises a coolant reservoir containing a coolant, arranged such that the coolant, in response to a pressure increase in the rocket motor upon firing of a propellent powder charge, is transferred from the coolant reservoir to the combustion gases in gas outlets of the rocket motor, wherein the coolant reservoir is arranged coaxially to the rocket motor and to a rocket motor nozzle, constituting an integral part of the rocket motor, the coolant reservoir being connected by at least two gas inlets to a combustion chamber-arranged in the rocket motor, for pressurization of the coolant, and by at least two coolant outlets to the rocket motor nozzle disposed in the rocket motor, for transfer of coolant from the coolant reservoir to the rocket motor nozzle during the whole or parts of a combustion process in the combustion chamber.
