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 .
