Abstract
The present invention provides a landing gear. The landing gear includes a trunnion having at least one principal pivot point. The principal pivot point is adapted to be pivotably coupled to an airframe to allow the trunnion to pivot about a principal trunnion pivot axis; the trunnion is operable to move between a deployed position and a stowed position by pivoting about the principal trunnion pivot axis. The trunnion further includes at least one secondary pivot point. The landing gear also includes a subframe having at least one principal pivot point. The principal pivot point of the subframe is pivotably coupled to the secondary pivot point of the trunnion to allow the subframe to pivot about a principal subframe pivot axis; the subframe is operable to move between a deployed position and a stowed position by pivoting about the principal subframe pivot axis. The landing gear further includes a wheel rotatably coupled to the subframe. The wheel is moved to a stowed position when the subframe pivots from the deployed position to the stowed position about the principal subframe pivot axis and the trunnion pivots from the deployed position to the stowed position about the principal trunnion pivot axis.
