Abstract
An intermediate casing for use in a gas turbine engine comprises inner and outer casing walls 2, 4, a support plate 6, supporting an axial end of each of the casing walls 2, 4, a splitter 8, and an array of vanes 10. At least one of the casing walls 2, 4, the support plate 6, the splitter 8 and the array of vanes 10 is formed from at least one blank of sheet material, such as steel. The formation of one or more components of the assembly from a flat blank of material provides a significant reduction in manufacturing cost.
