Abstract: An active vibration control actuator mount including at least one actuator bracket having an actuator interface member configured to hold one or more active vibration element thereon in one or more predetermined orientations, and an engine mounting structure interface member connected to the actuator interface member, the engine mounting structure interface member being configured to couple the at least one actuator bracket to an engine mounting structure, wherein the at least one actuator bracket is configured for the installation and removal of a respective active vibration element to and from the actuator interface member while a respective one of the at least one actuator bracket remains coupled to the engine mounting structure.

Abstract: An active vibration control system includes a plurality of actuators corresponding to and disposed adjacent each engine of an aircraft, at least one sensor located within a passenger cabin of the aircraft and configured to detect a magnitude and frequency of one or more of vibration and sound produced by a respective engine and generate one or more of a vibration and sound feedback signal, and a controller connected to each of the plurality of actuators and each of the at least one sensor, the controller being configured to effect control of no more than two of the plurality of actuators for a respective engine based the feedback signal where the no more than two actuators effect suppression of one or more of vibration and sound of a respective engine due to rotating axis of the respective engine.
