Abstract
A low-cost airliner defense system utilizing self powered, retrievable, towed decoys against man portable heat-seeking missile (MANPAD) systems provides both high power and a large IR radiating surface area. An efficient and lightweight integrated turbine-alternator extracts sufficient electric power from an air stream directed through a small decoy deployed and towed behind an aircraft during the vulnerable phases of a flight to power a large and intense IR emitter. Unfurled IR radiator “petals” present large area arrays of rear-facing IR emitters. During the high-altitude cruise phase the radiating petals furl down folding around the retrieved decoy body as it is stowed in a streamlined housing for minimizing fuel consumption and maneuverability penalties.
