Active airfoil vibration control

A method for changing a physical characteristic of an aircraft engine component utilizing an electromagnetic field, the method comprising the steps of:

• generating an electromagnetic field;
• and
• exposing a filler that is a part of an aircraft engine component to the electromagnetic field;
• and
• causing a physical property of the filler to change.

An apparatus for an aircraft engine that is configured for actively adjusting physical characteristics of a nonrotating-variable stator-vane, the apparatus comprising:

• an airfoil that extends between an inner end and an outer end;
• the outer end being rotatably engaged with an actuator;
• a transformable bushing that is configured to change stiffness when exposed to an electromagnetic field;
• and
• wherein at least one of the inner end and the outer end includes a trunnion that is received within the transformable bushing.
