Abstract
An articulated landing gear may include electrical lines and/or hydraulic lines located within the articulated landing gear. The articulated landing gear may have a hollow structural post and a hollow trailing arm coupled by a pivot joint. The electrical lines and/or hydraulic lines may be routed through an interior of the hollow structural post and through an interior of the hollow trailing arm. A bulkhead within the hollow structural post or the hollow trailing arms may include guide holes. The electrical lines and/or hydraulic lines may be supported by the bulkhead by passing through the guide holes. The electrical lines and/or hydraulic lines may be flexible around the pivot joint.
Claims19
An articulated aircraft landing gear comprising:
- a structural post;
- a trailing arm coupled to the structural post, wherein the structural post and the trailing arm are pivotably coupled at a pivot joint;
- an electrical line located at least partially within the structural post and located at least partially within the trailing arm;
- a hydraulic line comprising a first metallic portion located at least partially within an interior of the structural post, a second metallic portion located at least partially within an interior of the trailing arm, and a flexible portion coupled to the first metallic portion and the second metallic portion, wherein the flexible portion is routed around a reflex angle side of the pivot joint;
- and
- a deflector configured to protect the flexible portion around the pivot joint.
An aircraft landing gear comprising:
- a hollow structural post;
- a first bulkhead located within an interior of the hollow structural post;
- and
- an electrical line and a hydraulic line, wherein the hydraulic line passes through a first guide hole in the first bulkhead,
- wherein the hydraulic line comprises a first metallic portion located at least partially within the first guide hole, a second metallic portion, and a flexible portion coupled to the first metallic portion and the second metallic portion.
A system for routing an electrical line and a hydraulic line in an aircraft landing gear comprising:
- a structural post;
- a trailing arm coupled to the structural post at a pivot joint;
- and
- a bulkhead located within an interior of at least one of the structural post and the trailing arm;
- wherein the bulkhead secures the electrical line and the hydraulic line,
- wherein the hydraulic line comprises a first metallic portion located at least partially within the bulkhead, a second metallic portion, and a flexible portion coupled to the first metallic portion and the second metallic portion, wherein the flexible portion is routed around a reflex angle side of the pivot joint.
