ABSTRACT:
An airborne target for generating an exhaust plume simulating that of a jet powered aircraft embodies an elongated target body having an elongated combustion chamber therein. An air receiving inlet which faces in the direction of travel of the body communicates with the forwardmost end of the combustion chamber. An expansion chamber between the air receiving inlet and combustion chamber increases the expansion of air flowing toward the combustion chamber while at the same time reduces its velocity. A fuel injector is carried by the body to inject hydrocarbon fuel at a predetermined rate under pressure into the air to thus provide a predetermined fuel-air mixture. An igniter is carried by the body downstream of the fuel injector to ignite the fuel-air-mixture. A flame holder is carried by the body in position for the ignited fuel-air mixture to attach thereto and provide sustained burning after the igniter is spent. The sustained burning of the mixture thus produces an exhaust plume of a predetermined length which simulates the same spectral distribution of infrared energy as that produced from a jet engine burning the same fuel.
