Abstract
An articulated, retractible landing gear for helicopters and the like includes a three member drag brace assembly having a retraction brace pivotally connected to the helicopter fuselage at its inboard end and to an upper drag brace at its outboard end, with the latter pivotal connection being along the articulation axis of the landing gear, the upper brace being pivotally connected at its other end to a lower brace which in turn is connected to the oleo strut of the landing gear by a universal joint, the pivotal connection between the upper and lower braces in the extended position of the landing gear being on an axis normal to both the drag brace center line and the articulation axis.
