Heat exchanger support system

Claim 2

A mounting system for interconnecting a gas turbine engine with a heat exchanger allowing differing thermal expansion in said heat exchanger and said gas turbine engine, said heat exchanger including a first compartment and a second compartment, the mounting system comprising; air-in manifold means allowing translational motion of the heat exchanger towards and away from said gas turbine engine for communicating relatively cool gases exhausted from said gas turbine engine to said first compartment; air-out manifold means allowing rotational motion of said heat exchanger about a lateral axis relative said gas turbine engine and said heat exchanger for communicating said relatively cool gases from said first compartment to said gas turbine engine; gas-in manifold means allowing translational movement in the longitudinal axis of said gas turbine engine and said heat exchanger for communicating exhaust gases from said gas turbine engine to said second compartment; and bracket means acting in cooperation with the air-out manifold means for limiting vertical and horizontal motion of said heat exchanger.

Claim 3

The mounting means as set forth in claim 1 wherein said air-in manifold means comprises: a first bellows communicating with the gas turbine engine; a hollow horizontal member affixed on one side to said first bellows distal of said engine and communicating with the first compartment of the heat exchanger; a second bellows affixed to the other side of the horizontal member; a plate member affixed to the opposite end of said second bellows; a plurality of rods rigidly affixing said plate member relative said engine whereby said horizontal member is allowed to move relatively toward and away from said engine while communicating compressed gasses from said first bellows to said heat exchanger.

Claim 4

The heat exchanger mounting system as set forth in claim 2 wherein said air-out manifold means comprises: a trunnion mounting assembly including a pair of diametrically opposed pivot mounting brackets; a collar member affixed to said heat exchanger; a bellows assembly interconnecting said collar member with said gas turbine; and a pair of pivot pins rigidly affixed to said collar member and pivotally mounted in said pivot brackets whereby said heat exchanger is allowed to rotate about said pivot member in the lateral axis.

Claim 5

The mounting system as set forth in claim 3 wherein said bracket means comprises: a plurality of cantilever arms extending rearwardly and outwardly of said turbine engine; a laterally disposed mounting arm rigidly affixed to said cantilevered arms; a pivotal plate member pivotally mounted between said arm and said heat exchanger.

Claim 6

In a heat exchanger mounting system for a gas turbine engine, the gas turbine engine having a compressor outlet duct, a combuster inlet duct, and a power turbine exhaust serially aligned along the longitudinal axis thereof; and the heat exchanger unit comprising an elongated body having opposed upper and lower surfaces, an air-in manifold integrally connected to one end thereof, an air-out manifold and a gas-in manifold integrally formed in the one side adjacent the engine body; the mounting system comprising: linked bracket support means for supporting the second other end of the heat exchanger unit relative the engine; trunnion connection means for pivotally joining the air-out manifold with the combustor inlet duct; compensating bellows means for joining the air-in manifold with the compressor outlet duct, said compensating bellows means allowing limited vertical translational motion of the heat exchanger relative the engine; and clamp means for joining the gas-in manifold with the power turbine exhaust, said clamp means allowing limited horizontal translational motion of the heat exchanger relative the engine; the link bracket support means acting in cooperation with the trunnion connection means for controlling the vertical translational motion in the compensating bellows means and the horizontal translational motion in the clamp means.
