Abstract
An infrared radiation Coanda suppressor of an exhaust system encloses a Coanda surface for guiding exhaust gases into the atmosphere. The infrared radiation suppressor further uses cooling films for reducing the temperature of the Coanda surface and other exposed surfaces. A cool air entrainment flow of the exhaust gases prevents the buildup of recirculating hot gases in the exhaust chamber. As a result, IR radiation is suppressed from areas of the exhaust system which are exposed to IR detectors.
