AI Technical Summary

Problems solved by technology

However, during movement of the wire harness, friction against the fixed clamps may occur, which may damage the wire harness due to wear
[0006] Harnesses can also be routed through controlled harness routing, however such routing does not provide specific support for the bent sections of the harness and the harness may still bend at a radius of curvature smaller than its minimum bend radius

Embodiment Construction

[0031] With reference to the accompanying drawings, and more particularly to figure 1 , an aircraft is shown at reference number 1 and is generally described in this disclosure in order to illustrate some components for reference purposes. Aircraft 1 has a fuselage 2 comprising a front end in which a cockpit is arranged and a rear end supporting an empennage assembly, usually between the cockpit and the empennage assembly. The tail assembly includes a vertical stabilizer 3 with rudders and a horizontal stabilizer 4 with elevators. The empennage assembly has an empennage mounted on the fuselage, but other configurations can also be used for the aircraft 1, such as cruciform, T-shaped empennages and the like. Wings 5 ​​protrude laterally from the fuselage. Aircraft 1 has engines 6 supported by wings 5 ​​, but engines 6 could also be mounted to fuselage 2 . The aircraft 1 is shown as a jet engine aircraft, but could also be a propeller aircraft.

Abstract

A floating bend radius device for limiting a radius of curvature of a flexible tube having a minimum bend radius comprises first and second members. The first member has a curved contact surface having a radius of curvature at least equal to the minimum bend radius. The contact surface is concave in a plane transverse to the flexible tube's axial direction for contacting a portion of the flexibletube. The second member is engageable to the first member and complementary to the contact surface. The engaged members define a tube receiving space between the second member and the contact surfaceof the first member. The tube receiving space has a cross-sectional dimension configured to provide a compressive force on the flexible tube. At least one locking device may interconnect the members.A tube assembly including a bend radius device and a flexible tube is also discussed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 319,420, filed April 7, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] This application relates generally to the support of flexible pipes, and more particularly to the support of flexible pipes subjected to bending during use. Background technique [0004] In an aircraft, many components can move relative to each other when connected by flexible tubes such as electrical wiring harnesses. For example, main landing gear typically includes one or more electrical harnesses that connect to the aircraft structure. Each electrical harness undergoes bending as the main gear retracts and extends. A minimum bend radius for the wiring harness must generally be observed in order to avoid damage to the wiring harness and / or loss of function during retraction and / or extension of the main landing gear.
