The Child's Conception of Number

A stabilizing and support system for an augmenter cooling liner of a gas turbine engine is shown to include flange means which divide a cooling plenum formed between the cooling liner and an exhaust duct casing into a plurality of individual coolant chambers such that the pressure differential across the cooling liner can be closely controlled. The stabilizing and support system includes a plurality of stabilizers adapted to mount the cooling liner to the exhaust duct casing in such a manner as to define the cooling plenum therebetween. The stabilizers are captured on their outer ends by a stabilizer guide which permits relative thermal expansion to occur between the cooling liner and the exhaust duct casing, and each of the stabilizer guides is connected to a positioning band which is adapted to be mounted to the inside of the exhaust duct casing. In the preferred embodiment, the positioning band is provided with an integrally formed flange which defines a restricted inlet to each of the cooling chambers.
