Engine attachment pylon

摘要

An engine attachment pylon for mounting an aircraft engine to an aircraft structure while minimizing vibrations induced into the engine attachment pylon during flight and operation of the engine. The engine attachment pylon comprises a rigid box like structure housing a resonator which is tuned to attenuate tension and compression vibrations experienced by the engine attachment pylon. The engine attachment pylon is primarily used in combination within another identical engine attachment pylon, both being linked together on a vertical plane within the fuselage by a hinge like junction, and each engine attachment pylon being raised approximately 30° from the horizontal axis of the fuselage.

1. An engine attachment pylon, for mounting an aircraft engine to an aircraft structure, comprising:
a structure forming a box and comprising a first attachment member to connect to the engine and a second attachment member to connect to the fuselage; and, a dynamic mass absorber which is tuned to absorb vibrations of the aircraft engine, the dynamic mass absorber housed in the box and comprising a damping member suspended inside the structure and a lever, wherein the lever is pivotally mounted around a pivot, and connected at one end to a first end of the damping member and at the other end to a fitting mounted on one of the first attachment member or the second attachment member and wherein a second end of the damping member is attached to the other of the first attachment member or the second attachment member.
