A flap retractable control mechanism for rotating wings

Abstract

The present invention proposes a flap retractable control mechanism for rotating wings, including flaps, steering steering gear, steering gear connecting rod, flap connecting rod, filling plate connecting rod and filling plate; the steering steering gear is fixed on On the wall panel inside the rotating wing, one end of the connecting rod of the steering gear is fixed on the rotating end of the steering gear, which can be controlled to rotate within the airfoil section of the rotating wing, and the other end of the connecting rod of the steering gear is hinged to one end of the flap connecting rod , the other end of the flap link is hinged to the middle of the inner surface of the flap; the middle of the steering gear link is hinged to one end of the filler plate link, and the other end of the filler plate link is hinged to the inner surface of the filler plate; one end of the filler plate is fixed to the flap opening The rotation axis of the filling plate at the position is matched and can rotate around the rotation axis of the filling plate; the flap is installed on the outer edge of the rotating wing through the rotation axis of the flap. The invention can manipulate the filling plate to cover the concave cavity formed after the flap is opened while controlling the deflection and opening of the flap, so as to prevent the depression from affecting the effect of reducing drag and increasing lift of the flap.

Description

technical field [0001] The invention relates to the technical field of rotary wing design, in particular to a flap retractable control mechanism for a rotary wing. Background technique [0002] The applicant disclosed a rotary wing aircraft with variable flight mode in Chinese patent 201110213680.1. Its biggest feature is that there is a pair of rotary wings in the middle of the fuselage that can rotate at high speed as a rotor and can be locked as a fixed wing. Because it is necessary to take into account the use of both the rotor and the fixed wing, the airfoil of the rotary wing has chosen an elliptical airfoil. [0003] South Korea's Sungyoon Choi and Oh Joon Kwon published "Aerodynamic Characteristics of Elliptic Airfoils at High Reynolds Numbers" in the 45th issue of Jounral of Aircraft, and conducted a numerical calculation study on the aerodynamic characteristics of elliptical airfoils with different relative thicknesses. The results show that because the blunt trail...
