Aerocraft control plane transmission structure

The utility model belongs to the field of aerocraft structural design, and relates to improvement on an aerocraft control plane transmission structure. The aerocraft control plane transmission structure comprises a central rotating shaft, a control plane rocker driving pull rod rotating shaft, a strengthener actuating cylinder rotating shaft, a Y-shaped main transmission structure and a rocker driving pull rod, wherein the Y-shaped main transmission structure is arranged on a main plane or a machine body structure through the central rotating shaft, and comprises an actuating cylinder support arm and a pull rod support arm which are crossed to form the Y-shaped structure; the actuating cylinder support arm is connected with a strengthener actuating cylinder through the strengthener actuating cylinder rotating shaft; the pull rod support arm is connected with the rocker driving pull rod through the control plane rocker driving pull rod rotating shaft. The aerocraft control plane transmission structure is arranged between a control plane and the main plane, and the strengthener can be placed in the machine body, so as to eliminate huge bumps caused by the strengthener; maintenance of a covering cap on the main plane of an aerofoil is not required, so as to avoid damage on a main force bearing structure, and improve the structural efficiency.
