Patent ID: 6843450

Claim:
An aircraft system, comprising: an airfoil portion configured to be positioned external to an aircraft fuselage; a connecting portion configured to rotatably connect the airfoil portion to the fuselage; and a roller arrangement positioned to be coupled between the connecting portion and the fuselage, the roller arrangement including: a roller support coupleable to one of the fuselage and the connecting portion; an arcuate track coupleable to the other of the fuselage and the connecting portion, wherein the arcuate track includes a flange portion having a contact surface, and a web portion disposed inwardly from the flange portion, the web portion being generally normal to the flange portion; a first roller rotatable about a first axis and rotatably carried by the roller support, the first roller having an external surface, the external surface of the first roller being in load bearing contact only with the contact surface of the arcuate track; and a second roller having an external surface in contact with the web portion, the second roller being rotatable about a second axis generally normal to the first axis, the first and second rollers restricting motion of the airfoil portion relative to the arcuate track in directions generally normal to the first and second axes while allowing the connecting portion to rotate relative to the arcuate track.
