Abstract:
A truck beam for an aircraft landing gear assembly is provided. The truck beam includes an elongate hub having first and second ends. The hub is rotatably mountable a shock strut of the landing gear assembly. A first leg extends radially in a first direction from the first end of the hub. The first leg has an inner side facing the second end of the hub and is configured to have a first wheel rotatably mounted to the inner side about a first wheel axis. A second leg extends radially in a second direction from the second end of the hub and has an inner side facing the first end of the hub. The second leg is configured to have a second wheel rotatably mounted to the inner side of the second leg about a second wheel axis.
Abstract:
A structural component, or parts thereof, for a machine system or vehicle, such as an aircraft, is provided. In some examples, the structural component includes at least one embedded passageway or line. In other examples, the passageway or line is formed integrally on the exterior surface of the structural component. In some of these examples, the structural component can benefit from additive manufacturing techniques or methodologies.
