An aft engine mount, for use in supporting a jet engine from a wing of an aircraft occupies a minimum amount of the space between the wind and the engine, permitting a maximum vertical dimension (depth) of the engine-mounting strut. The mount includes a yoke, the arms of which are pivotally attached to the engine. The yoke is in turn attached to a vibration isolator mounted within an isolator housing that is affixed to the engine-mounting strut. The isolator housing is preferably mounted in a recess in a lower surface of the strut to provide for maximum effective strut height. The vibration isolator includes a pair of support fittings, each of which is contained within an associated compartment formed in the isolator housing. Each support fitting includes first and second ends surrounded by a resilient material to provide a close fit of the support fitting within the housing. The resilient material surrounding the ends of the support fitting provides damping of vertical vibration. Plugs of resilient material are placed adjacent each end of the support fittings between such ends and the adjacent end walls of their associated compartment. The plugs damp out sideways vibration. Preferably, the resilient material used for vibration damping is resistant to the high temperature that are present in the area of the engine.
