Abstract: PROBLEM TO BE SOLVED: To provide a gas turbine engine with a variable area nozzle requiring no large-scale maintenance without largely increasing the total weight of the gas turbine engine. SOLUTION: The gas turbine engine 10 includes a variable area nozzle 30 having a plurality of flaps 38. The flaps 38 are actuated by a plurality of actuating mechanisms 40 to be driven by a shape memory alloy(SMA) actuator 68. The SMA actuator 68 has a deformed shape in a martensitic state and a basic shape in an austenitic state. The SMA actuator 68 is heated to transform from the martensitic state into the austenitic state generating a force to actuate the flaps 38. The variable area nozzle 30 also contains a plurality of return mechanisms 42 for deforming the SMA actuator 68 when in the martensitic state.

Abstract: A gas turbine engine (10) includes a variable area nozzle (30) having a plurality of flaps (38). The flaps (38) are actuated by a plurality of actuating mechanisms (40) driven by shape memory alloy (SMA) actuators (68) to vary fan exist nozzle area (36). The SMA actuator (68) has a deformed shape in its martensitic state and a parent shape in its austenitic state. The SMA actuator (68) is heated to transform from martensitic state to austenitic state generating a force output to actuate the flaps (38). The variable area nozzle (30) also includes a plurality of return mechanisms (42) deforming the SMA actuator (68) when the SMA actuator (68) is in its martensitic state.

Abstract: Improved Superalloy Properties Through Stress Modified Gamma Prime Morphology A high strength nickel base superalloy having a novel microstructure is described. The article consists of a gamma matrix containing a oriented gamma prime second phase having a plate or rod form. This noncuboidal gamma prime phase is produced by aging solution treated material under an applied stress. When this process is applied to a certain class of superalloys which are rich in refractory elements, the resultant structure provides exceptional resistance to creep at elevated temperatures.
