the front of the flaperon referring in particular now to fig3 a and 3b it can be seen that a roller assembly 47 is mounted at the rear of a downward extension 49 of the beam 18b it engages a track 51 which extends downward from the side of the flaperon and is adapted to swivel in its mount not shown to further support the flaperon in its forward and rearward movement an identical mounting system is incorporated in the beam 18c fig1 on the outboard side of the flaperon and therefore is not described in detail the flaperon is thereby provided with a four point support as are all the flaps still referring to fig3 a it can be seen that rotation of the threaded shaft 28 drives the ball screw assembly 35 causing it to translate toward the trailing edge 6 of the wing additionally causing the attached flaperon 12 to extend backward and downward in a path indicated by the shape of the track 51 mounted on the wing forward of and above the gear box 24e is a motor 53 preferably hydraulic control of the motor i e whether it turns clockwise or counterclockwise is accomplished in an entirely conventional manner by movement of the pilot 39 s control wheel in the flight station via a control system since this motor control system need only be state of the art and is not significantly a part of the invention it is not disclosed in further detail furthermore an electric motor with an electrical control system may be substituted and remain compatible with the instant invention the motor 53 is connected to a splined shaft 55.
