1. A variable camber Krueger flap deployment linkage mechanism comprising:
a first linkage assembly configured to couple to a flap assembly and an airfoil, the first linkage assembly comprising:
a first drive arm configured to couple to an actuator coupled to the airfoil, and configured to rotate in a chord-wise plane;a first drive link coupled to the first drive arm and a trailing end of the flap assembly; anda support arm coupled to a middle link portion of the first drive link and configured to rotatably couple to the airfoil at a rotation joint; and a second linkage assembly configured to couple to the flap assembly and the first drive arm, the second linkage assembly comprising:
a drive transfer arm coupled to the flap assembly;a middle connection segment configured to couple the drive transfer arm to the trailing end of the flap assembly; anda bullnose link configured to couple the drive transfer arm to a bullnose portion of the flap assembly.
