Engine fastener of a mounting system interposed between an attachment strut and an aircraft engine

Abstract

The invention concerns an engine fastener of a mounting system designed to be interposed between a rigid structure of an attachment strut of an aircraft engine and engine, the fastener comprising a main body (130), a control bar mounted articulating on the main body via a pivot bolt (144), as well as two thrust load absorbing link rods each provided with one end connected on the control bar, the main body consisting of a first main bracket (132a) and a second main bracket (132b) superimposed on the first. The invention is characterized in that the pivot bolt (144) consists of a first portion (144a) and a second portion (144b), the first portion being made in one single piece with the first bracket and the second portion being made in one single piece with the second bracket. Moreover, the brackets (132a, 132b) define an abutting surface (166) capable of limiting the rotation of the control bar (146).

Description

technical field [0001] The present invention relates generally to engine accessories of a mounting system designed to fit between the rigid structure of an accessory strut of an aeroengine and the engine, and more particularly (but not exclusively) to a front accessory which is Designed to absorb forces exerted along the longitudinal, lateral and vertical directions of the engine. [0002] The invention also relates to a mounting system designed to be mounted between the rigid structure of an aeroengine accessory strut and the engine, wherein the system can be used regardless of the position of the engine relative to the position of the accessory strut. Background technique [0003] An aircraft accessory strut is provided to facilitate forming a connection interface between an engine and a wing of the aircraft. The accessory struts transmit the forces generated by the aircraft's engines to the aircraft's structure and also allow the passage of fuel, electricity, hydraulics ...

AI Technical Summary

Problems solved by technology

[0014] Also, the need to provide this rear exclusively to accommodate the hinge pins of course means that the overall weight and size of the body is not optimized

Moreover, the remote location of the bearings housing the hinge pins necessitates the presence of two very long rods, which is also disadvantageous in terms of the overall size and weight of the front attachment

[0015] Finally, it should be noted that the difference in thickness between the central and rear parts of the attachment body leads to difficulties in transmitting forces in the attachment
