Electric boost actuation system for translating rings

A method of actuating a translating ring of a gas turbine engine, wherein the translating ring is oriented about a centerline, the method comprising:

• applying a first mechanical force at a first location about the translating ring, using at least one hydraulic actuator, to translate the ring in an axial direction;
• sampling, using a controller, at least one sensed engine condition;
• determining, using the controller, an operating condition of the gas turbine engine based upon the at least one sensed engine condition;
• and
• applying a second mechanical force at a second location about the translating ring, using at least one electric actuator physically separate and circumferentially offset from the at least one hydraulic actuator about the centerline, to translate the ring in the axial direction based upon the operating condition of the gas turbine engine and wherein the first location and the second location are spaced apart by a distance along a circumference of the translating ring and at a common axial location along the centerline.
