US 5,176,339 A · Resilient pivot type aircraft mounting

Abstract

A pivot type aircraft mounting for resiliently connecting a structure to an aircraft engine which uses a pivoting and siding joint on a beam at the engine attachment point, a vertically stiff and laterally soft intermediate pivot joint on the beam, and a resilient compression section near the end of the beam for reacting the engine loads into the structure and providing the desired spring rates in the vertical and lateral direction. The invention can utilize low friction pivoting and sliding joints such as nylon lines bearings or elastomeric bearings. The compression section can be metal mesh for high temperature applications or of elastomeric or laminated elastomeric construction for normal operating temperatures. The remote location of the compression section is particularly well suited for addition of fluid for adding damping or tuned absorber effects.

Dependent claims

A resilient engine mounting for flexibly attaching an aircraft engine to a structure, comprising:

(a) a first pivot means slidably receiving a first portion of a beam for connecting said beam to said engine about said first portion of said beam and accommodating pivoting motion and sliding motion of said beam relative to said engine;
(b) spring means attached at a second portion of said beam spaced along said beam from said first portion, said spring means reacting engine loads into a housing;
(c) a second pivot means located in said housing at a third portion of said beam intermediate said first portion and said second portion, said second pivot means reacting loads into said housing and allowing pivoting of said beam relative to said housing.
