Abstract
The high pressure turbine of a gas turbine engine is provided with an annular array of aerofoil rotor blades which are surrounded by a shroud. The shroud is mounted on a tubular diaphragm which is deflected by pressure modulation to vary the effective diameter of said shroud means. An L-shaped cross-section flange provided on the turbine casing cooperates with a plurality of L-shaped cross-section hooks on the diaphragm to limit radially inward movement of the shroud and thereby prevent contact between the aerofoil blade tips and the shroud means.
