ABSTRACT:
1. In a gas turbine engine having blades and an exhaust tailpipe, the combination of an exhaust cone axially mounted within the tailpipe and having its rearward end adjacent the discharge opening of the exhaust pipe with substantially all of the externally viewable surfaces of said exhaust cone formed of porous stainless steel material, means to supply cooling air to the interior of the cone for venting thereof through said porous material, a hollow strut member of airfoil configuration spanning the annular gas passageway between the exhaust tailpipe and the said cone with substantially all of the externally viewable surfaces of said strut member formed of stainless steel material, means to supply cooling air to the interior of said hollow strut member, means to pass cooling air in heat interchange relation with the outer surface of substantially all parts of the exhaust tailpipe whose related inner surface is externally viewable, and a constriction in the exhaust tailpipe located downstream of the hot parts of the engine and serving with the exhaust cone to conceal the hot parts of the engine from external view, whereby the detectible infrared emission of the engine is substantially reduced.
