ADJUSTMENT OF WINGS FOR VARIABLE CAMBER FOR OPTIMUM TAKE-OFF AND LANDING CONFIGURATION

摘要

This application is directed to moving flaps differentially to produce better lift/drag characteristics during takeoff and landing of aircraft. A method and apparatus for differentially adjusting a first deployable lift device ("FDLD") and a second deployable lift device ("SDLD") on a wing are described. The FDLD and the SDLD are coupled to a single power drive link. A first desired position for the FDLD and a second desired position for the SDLD are determined. A motor moves the FDLD by a first movement amount determined by subtracting a first position of the FDLD from the first desired position. A second movement amount for the SDLD is determined by subtracting a second position of the SDLD from the second desired position. A differential movement amount is determined by subtracting the first movement amount from the total amount the SDLD will move. Another motor moves the SDLD by the differential movement amount.
