The invention discloses a double-duct aircraft grid control surface course control mechanism, which comprises a front group of grid control surfaces and a rear group of grid control surfaces, namely a front grid control surface and a rear grid control surface, the front grid control surfaces are arranged below clockwise rotating front duct blades, and the rear grid control surfaces are arranged below anticlockwise rotating rear duct blades; and the front grid control surface and the rear grid control surface independently control the left and right deflection of the grid control surfaces respectively. The method is used for course control of the double-duct aircraft and balance adjustment of the asymmetric reverse torque of the double ducts, when the front and rear double-duct control surfaces deflect towards one side at the same time, the aircraft obtains lateral control force and achieves transverse movement, and when the front and rear double-duct control surfaces deflect in the opposite direction, the aircraft obtains course deflection torque and achieves steering movement. The front duct and the rear duct generate lift force difference, so that the aircraft obtains front-back level flight capacity and pitching control capacity, and generated asymmetric reverse torque is compensated by reverse differential motion of a grid control surface.
