Abstract
An aircraft assembly includes a wing, a pylon structure attached to the wing, an aft engine mount attached to the pylon structure, and an engine attached to the aft engine mount. The aft engine mount includes a pivotal attachment to the pylon structure and first and second spring beams operatively connected to the pylon structure at opposing sides of the pivotal attachment for damping pivotal movement of the engine with respect to the pylon structure to enable tuning of the natural frequency of the engine to avoid wing flutter.
