Patent ID: 8646724

Claim:
A system for attaching two components together, the two components including an engine of an aircraft and a mounting pylon of the engine that is integral with structure of the aircraft, the system comprising: front trunnions and rear trunnions positioned with respect to a longitudinal axis X of the engine and according to an orthonormal reference point XYZ, the front and rear trunnions being contained in planes YZ perpendicular to the longitudinal axis X, wherein at least two of the front trunnions or the rear trunnions are vibrational damping trunnions; wherein the at least two vibrational damping trunnions are identical to each other and are arranged on opposing sides of the pylon and the engine; and wherein each of the at least two vibrational damping trunnions further comprises: a suspension assembly defining an arm with first and second ends, the arm being rotatably connected to the pylon around a jointing axis parallel to the longitudinal axis X; a resonant mass coupled to and supported by the first end of the arm, which is free from connection to the pylon; an elastic element connecting the second end of the arm and the pylon; and at least one shackle having one end attached to the engine and another end attached to the arm of the suspension assembly, wherein the arm of the suspension assembly has a bent shape which surrounds a portion of the external periphery of the engine, such that the first end and resonant mass are free to rotate about the jointing axis in order to dampen vibrations between the engine and the mounting pylon.
