Abstract
A shroud liner has a hooked downstream end passing between a stator vane and a casing so that in operation the gas loads on the vane cause the liner to be held between the vane and the casing. The shroud liner also has a resilient upstream end fitting between a second stator vane and the casing so that in operation gas loads on the vane cause it to move towards the casing, compressing the shroud liner. As a result the shroud liner is securely held in place at its downstream end, but can slide relative to the casing and vanes at its upstream end to allow for thermal expansion.
