Mounting Device For Aircraft Supply Systems

Abstract

A mounting device for aircraft supply systems comprises a cross member (10) and at least one support module (40) including a body having a shape complementary to that of a cross member. The body includes an opening and a device for securing an aircraft supply system (2). Furthermore the at least one support module (40) comprises a pin, wherein the opening forms a guide that is able to receive a portion of the pin. The cross member (10) includes grooves (101) that are regularly spaced apart in the direction of elongation of said cross member (10). The pin has a shape complementary to that of the grooves and has a lip transverse to the direction of elongation of the pin. The support module is anchored to the cross member by the pin being inserted into the opening, the pin engaging with one of the grooves, as far as an anchoring position in which the lip is in contact with the support module (40).

Description

technical field [0001] The invention relates to a mounting device for an aircraft supply system. Background technique [0002] In order to supply the various systems present in the aircraft, it is necessary to install the associated (electrical, hydraulic, pneumatic, etc.) supply systems. These supply systems are in the form of wiring, piping, and other pathways. These supply systems are arranged on the fuselage structure, in particular between frames holding the fuselage structure in the plane of the fuselage structure section. These frames are connected to reinforcements provided by spars along the longitudinal axis of the aircraft. Since the space available for installing the supply system is mainly provided in the region of the girders and panels forming the skin of the aircraft, the volume for installing the system in the pressure compartment is critical. [0003] Thus pipes, wires, wire assemblies, electrical wiring or stranded wires are mounted on the frame above t...

AI Technical Summary

Problems solved by technology

[0016] Said device has the disadvantage that the fastener support is only weakly fastened to the rail

[0018] It is therefore possible that the spacing between the equipment (supply systems) cannot be kept constant, and this proves to be particularly harmful when said equipment comprises wires: the known separation distance of the wires is not maintained

[0019] It is to be noted here that the isolation distance corresponds, for example, to the distance at which two wires should be separated in order to limit the effects due to electromagnetic interference

[0020] Finally, the device present in said document is not particularly easy to use, since, in order to fasten the fastener support to the rail, it is necessary to lock the elastic grip of the fastener support in the rail by means of a snap ring. position, where part of the snap ring is wedged in the opening made in the wall of the fastener support, this operation is very complicated for the operator
