Abstract: A steering apparatus may comprise a strut cylinder, a steering collar, a first linear actuator, a first drive gear, a crankshaft, and a ring gear. The ring gear may be coupled to the steering collar. The first drive gear may be fixed to the crankshaft and coupled to the ring gear such that the steering collar rotates in response to rotation of the crank shaft. The first linear actuator may be coupled between the crankshaft and the strut cylinder.

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.
