Abstract
The combustion equipment of a gas turbine engine comprises an annular flame tube and a support casing both subjected to relatively high temperatures. Engine acceleration or engine deceleration causes the temperature in the combustion equipment to increase or decrease respectively, and this results in either expansion or contraction of the annular flame tube and the support casing. The annular flame tube has a greater rate of thermal expansion/contraction than that of the support casing and this results in distortion or cracking of the combustion equipment if the annular flame tube and support casing are rigidly mounted to each other. To overcome this problem a relatively flexible support structure which has a generally U-shaped cross-section is positioned radially between the annular flame tube and the support casing, and a first limb of the flexible support structure is secured to the annular flame tube and a second limb of the flexible support structure is secured to the support casing, and the flexible support structure permits relative radial movement of the annular flame tube and the support casing.
