Abstract

A fan blade (60) for a gas turbine engine comprises a blade body (68) and a shape memory alloy actuator (84). The blade body has a pressure side (70) disposed opposite a suction side (72). Each of the pressure side and the suction side extends radially from a root (74) towards a tip (76) and extends axially from a leading edge (78) towards a trailing edge (80). The blade body defines a passageway (90) that is disposed between the pressure side and the suction side. The shape memory alloy actuator is received within the passageway and is operatively connected to the blade body. An alternative embodiment of a fan blade (60) comprises a cellular structure that extends radially from a root (74) towards a tip (76) and extends axially from a leading edge (78) towards a trailing edge (80), the cellular structure defining a blade body (68), the cellular structure having a first portion defining a shape memory alloy actuator (84) that is disposed between the leading edge and the trailing edge and extends from the root towards the tip. A gas turbine engine comprises a fan section, a compressor section, a combustor section, a turbine section, and a fan blade comprising a blade body (68) and a shape memory alloy actuator (84) operatively connected to the blade body; and a sensor assembly (62) in communication with the shape memory alloy actuator arranged to provide a signal indicative of vibration of the fan blade .
