NOVELTY - The flap deployment linkage mechanism (500) has two linkage mechanisms (508) coupling a flap assembly (502) and an airfoil. One linkage assembly has a first drive arm (512) coupled to the airfoil and rotatable in a chordwise plane (560), a drive link (514) coupled to the drive arm and the trailing end of the flap assembly, a support arm (516) coupled to the middle link portion (520) of the drive link and rotatably coupled to the airfoil at a common joint (522). The other linkage mechanism has a second drive arm (524), a rotation control arm (526), and a drive transfer arm (530).    USE - Flap deployment linkage mechanism, particularly a variable camber Krueger flap mechanism, for enabling natural laminar flow over fluid-dynamic body for use in aircraft. Can also be applied to hydrofoils, wind turbines, tidal power turbines, or other fluid dynamic surface.    ADVANTAGE - The high-positioned, three-position variable camber Krueger flap provides high lift capability and bug shielding to enable natural laminar flow, and avoids transition stalls during deployment.    DETAILED DESCRIPTION - The flap deployment linkage mechanism (500) has two linkage mechanisms (508) coupling a flap assembly (502) and an airfoil. One linkage assembly has a first drive arm (512) coupled to the airfoil and rotatable in a chordwise plane (560), a first drive link (514) coupled to the first drive arm and the trailing end of the flap assembly, a support arm (516) coupled to the middle link portion (520) of the drive link and rotatably coupled to the airfoil at a common joint (522). The other linkage mechanism has a second drive arm (524) coupled to rotatably to the first drive arm, a rotation control arm (526) coupled to the second drive arm and airfoil to control rotation of the second drive arm, a drive transfer arm (530) coupled to the middle flap portion (532) of the flap assembly and rotatably coupled to the airfoil at the common joint, and a second drive link (528) rotatably coupled to the middle transfer arm portion (536) of the drive transfer and the second drive arm. An INDEPENDENT CLAIM is also included for a method to enable natural laminar flow over a fluid-dynamic body using a variable camber Krueger flap mechanism.
