Unmanned airborne target, for ground-to-air or air-to-air weapons system uses IR radiator positioned in exhaust gas stream of heat generating unit

摘要

The airborne target has at least one IR radiator (2a,2b) positioned within the exhaust gas stream of a heat generating unit, so that the surface of the IR radiator is fully enclosed by the exhaust gas stream. The IR radiator extends in the flow direction of the exhaust gas stream and has a cross- or star-shaped cross-section. A flame holder can be provided for localized heating of the IR radiator.
