FIELD: machine building. SUBSTANCE: mesh aerodynamic surface contains a power frame consisting of two sidewalls, a root and end plans in the form of metal plates, and support of the power frame attachment to the control mechanism of the mesh aerodynamic surface. Inside the power frame made with slots there is a set of thin flat plans with wedge-sharpened faces arranged at angle of 45° to two sides framing it, a root and end plans. Lattice is made in the form of square cells with protrusions on end faces of thin plans and slots on front and inner sides of side walls, root and end plans for ledges and end faces of thin plans. EFFECT: invention is aimed at increasing strength and rigidity of the structure.
