In a gas turbine engine, conduit [90] delivers pressurized cooling air to a selected group of hollow [87,70,71] struts at a temperature sufficient to induce thermal contraction of the selected group of hollow struts, thereby opposing a downward shift in the rotor axis during high power engine operation, and maintaining a circumferentially uniform tip clearance. Air baffles disposed in the cooled struts ensure radially uniform thermal contraction and efficient heat transfer. <IMAGE>
