Abstract:
A flaperon operating device in an airplane having left and right main wings and left and right flaperons vertically movably mounted respectively on the trailing edges of said left and right main wings, wherein said left and right flaperons are moved vertically in reverse phases to control the rolling moment of the airplane, moved vertically in the same phase to control the lifting power or the pitching moment of the airplane, and moved vertically in the same phase by a small steering angle to control the drag of the airplane; said flaperon operating device comprising a rotor shaft extending in the longitudinal direction of the airplane, a rotor mounted for clockwise and counterclockwise rotation about said rotor shaft, a slider mounted for clockwise and counterclockwise rotation in unison with said rotor and for longitudinal movement along said rotor shaft, a first left link pivotally supported at one end thereof on said rotor shaft, a first right link pivotally supported at one end thereof on said rotor shaft, a second left link pivotally supported at one end thereof on said slider and at the other end thereof at an intermediate portion or the other end of said first left link, a second right link pivotally supported at one end thereof on said slider and at the other end thereof at an intermediate portion or the other end of said first right link, a third left link pivotally supported at the laterally inner end thereof at the other end of said first left link and operably coupled at the laterally outer end thereof to said left flaperon, and a third right link pivotally supported at the laterally inner end thereof at the other end of said first right link and operably coupled at the laterally outer end thereof to said right. flaperon, whereby said left and right flaperons are vertically moved in reverse phases by rotating said rotor and said slider clockwise or counterclockwise about said rotor shaft and moving said third left and right links laterally in the same direction through said second left and right links and said first left and right links, and said left and right flaperons are vertically moved in the same phase by moving said slider longitudinally along said rotor shaft and moving said first left and right links and said third left and right links in the laterally opposite directions through said second left and right links.
