Abstract

A combustion chamber is supported in a gas turbine engine by a mounting having a first attachment assembly secured to a wall of the combustion chamber, and a second attachment assembly secured to a support structure rigidly mounted from an engine housing. The first attachment assembly includes a pair of clamp surfaces pressed by a spring to grip parallelly-spaced inner and outer surfaces of the wall. Radial thermal expansion and contraction of the wall, relative to the first attachment assembly, are accommodated by allowing radial slippage between the clamp surfaces and the gripping surfaces. The second attachment assembly includes a spring which permits the combustion chamber and the mounting to tilt relative to the support structure. By accommodating both differential radial movement and tilting, the thermal stresses in the material forming the combustion chamber are reduced.
