Abstract
A combustion chamber for a gas turbine engine having a step-liner configuration and providing a double wall defining an annular confined cooling air flow passage along the outer surface of the chamber. The outer wall of the double-wall configuration is provided by a concentric cylindrical baffle member supported in radially spaced relation from the combustion chamber wall by a plurality of leaf spring members providing a biasing force between the combustion chamber wall and the baffle member so that relative thermal growth between the combustion chamber wall and the baffle can be accommodated by deflection of the support springs or by axial sliding between the springs and the chamber wall.
