Problems solved by technology

[0008] There is therefore a high risk of separation of the equipment supported by these dampers; due to the relative weight of the equipment (10-15 kg), the detached equipment may in turn collide with and damage the engine nacelle

Embodiment Construction

[0037] figure 1 and figure 2 A piece of electrical equipment 10 is shown fixed on a cowling 12 of an aeroengine by means of the device according to the invention. The device can also be used to secure a piece of non-electrical equipment to an aircraft engine cowling.

[0038] Aeroengines generally comprise a turbine engine, for example of the turbojet type, and are mounted coaxially inside an apparently cylindrical nacelle. The device 10 is mounted, for example, on the cowling or nacelle structure of the engine. The device 10 may be a computing unit, a control unit or a power supply unit for driving an engine thrust reverser, for example.

[0039] In the example shown, the device 10 has a substantially parallelepiped shape and is constituted at one end by connection means 14 for connection with the other electrical equipment of the engine. The fairing 12 has an annular shape and may carry one or more other pieces of equipment.

[0040] Such equipment is sensitive to vibr...

Abstract

A device for supporting and securing a piece of equipment on an aircraft engine or nacelle case, including a vibration damper including a first part secured to the case and a second coaxial part rigidly connected to the piece of equipment, the damper associated with a safety member configured to hold the damper in place on the case in the event of damper failure or breakage. The safety member, which is independent of the damper, is mounted astride the damper and secured to the case.

Description

technical field [0001] The present invention relates to a device for supporting and fixing equipment on an engine nacelle cowling or an aeroengine cowling, whereby such a device allows the equipment to be suspended so as to protect the equipment from vibrations and shocks during operation. Background technique [0002] An aero-engine consists of a turbine engine surrounded by an engine nacelle which may carry one or more pieces of equipment, for example electrical equipment such as a computing unit, a control unit and / or a power supply unit, whereby by means of vibration dampers A device secures each piece of equipment to the cowling of the engine nacelle. It is also possible to fix the device to the spinner of the vortex engine by means of vibration dampers. [0003] In known manner, each damper is composed of a first part fixed to the fairing and a second part mounted coaxially around the first part and connected to the first part by elastically deformable means. The sec...
