DEVICE FOR REDUCING THE IR DESTINATION SIGNATURE OF AIRCRAFT

摘要

Device for reducing the IR target signature of aircraft threatened by guided missiles with IR seeker heads comprises a high pressure tank (1) containing a piston (4) dividing the inner chamber of the tank into a gas chamber (3) and a liquid chamber (2) and moving between two end stops (15, 16), a pump (5) for filling the high pressure tank with cooling liquid, one or more gas generators (7) with solid propellant arranged in or connected to the gas chamber so that gas escaping from the gas chamber on ignition of the solid propellant moves the piston in the high pressure tank, a jet system (13) spraying the liquid directly into the exhaust gas, and a pipe or tube system (10) distributing the cooling liquid from the high pressure tank to the jet system. Preferred Features: The cooling liquid is kerosine or solene.
