| Abstract | An exemplary embodiment of the invention is directed to a turbine engine (10) having a first, rotatable turbine rotor assembly (58), a second, stationary nozzle assembly (52) disposed adjacent thereto and a wheel space (74) which is defined between the first, rotatable turbine rotor assembly and the second, stationary nozzle assembly. The wheel space (74) is operable to receive cooling air (80) therein and includes a sealing feature (96) located on the first rotatable turbine rotor assembly (58) that extends axially into the wheel space (74) to terminate adjacent to a sealing land (102) positioned on the second, stationary nozzle assembly (52). The sealing feature (102) and the sealing land (96) operate to control the release of cooling air from within the wheel space (74) and the sealing land (102) is constructed of shape memory alloy. |
