<p>A system for removing and/or preventing ice build-up on an aircraft includes at least one heat exchanger (10, 60, 66, 72, 78) mounted within an aperture (22) in the tailpipe of a gas turbine engine (14). The heat exchanger includes an inner plate (26) having a surface (40) which faces inwardly into the tailpipe and which is in direct contact with the heated exhaust gas in the tailpipe, and an outer plate (30) with a surface (43) facing outwardly from the tailpipe and in direct contact with a cooler air stream passing around the turbine engine core. A series of heat exchange fins (42) are formed on the inner plate to direct exhaust gas across the inner plate, and a series of heat exchange fins (44) are formed on the outer plate to direct the cooler air across the outer plate. Heat transfer fluid (34) flows between the inner plate and the outer plate and absorbs heat energy from the exhaust gas. The heat transfer fluid flows through a filter (82), accumulator (84) and pump (86) system to heat transfer structure (62, 64, 68, 70, 74, 76, 80) integral with the exposed portions of the aircraft. The heat transfer fluid transfers heat energy to the exposed portions of the aircraft to reduce and prevent ice build-up on the aircraft. When the system is not active, excess heat energy is transferred from the heat exchange fins on the outer plate to the cooler air flow to prevent vaporization or boiling of the heat transfer fluid.</p> |
