A support device, an aircraft engine, and an aircraft

Abstract

This invention relates to a support device, an aero-engine, and an aircraft, belonging to the field of aerospace technology, and solves the problem that existing aero-engine control unit support devices do not meet the vibration reduction requirements of the control unit. The invention includes a vibration-damping bracket and a first vibration-damping assembly; the first vibration-damping assembly is disposed on the vibration-damping bracket and is used to suppress vibration of the bracket in a first direction; wherein, the first vibration-damping assembly includes a movable plate, a fixed plate, and an elastic block; the elastic block is disposed between the movable plate and the fixed plate, and its stiffness can change with the movement of the movable plate; a stiffness adjustment structure is provided inside the elastic block; the first vibration-damping assembly adjusts the internal stiffness of the elastic block through the stiffness adjustment structure to suppress the vibration of the bracket. This invention reduces the vibration of the engine frame and improves the stability of the frame.
