Aircraft engine mount

Abstract

An aircraft engine mount for mounting an engine to an aircraft includes a mounting frame fixedly joined to the aircraft, first and second prime links and a waiting failsafe link. The first prime link is joined to the engine at a first joint and to the mounting frame at second and third joints. The second prime link is joined to the engine at a fourth joint and to the mounting frame at fifth and sixth joints. The waiting failsafe link is joined to the engine at a seventh joint and to the mounting frame at an eighth joint. The first, third, fourth, sixth and seventh joints are ball joints, and the second and eighth joints are translating ball joints. The fifth joint is a clearance pin joint. All of the translating ball joints include a spherical bearing disposed in an opening in the respective link and a pin extending through the spherical bearing. An inner bushing is disposed on the pin and an outer bushing disposed over the inner bushing. The inner bushing has an oppositely disposed set of planar surfaces formed on its outside diameter, and the outer bushing has an oppositely disposed set of axially extending planar surfaces formed on its inside diameter. Each one of the set of planar surfaces formed on the outer bushing slidingly engages a corresponding one of the set of planar surfaces formed on the inner bushing.
