A method for suppressing infrared radiation from an engine of an aircraft operating in an environment includes directing hot exhaust from the aircraft engine into a lobed mixer of a single baffle infrared suppressor having a collapsible, translatable baffle to generate alternating flows of hot exhaust gas and cold air. The method further includes directing the alternating flows of hot exhaust gas and cold air towards the single baffle assembly to mix the hot exhaust gas with the cold air.

One-piece baffle infrared suppressor apparatus and method

An infrared signature suppression system for reducing infrared radiation emitted by a vehicle. The system includes an elongate duct mounted on the vehicle having a hollow interior extending along an axial centerline between an upstream end and a downstream end for transporting exhaust gas emitted by the vehicle, and a baffle positioned in the hollow interior of the duct between the upstream end and the downstream end. At least a portion of at least one of the duct and the baffle includes an emissivity coating for reducing infrared radiation emitted by the vehicle.
