Problems solved by technology

This scheme only considers the tilting system as an independent device, without considering the combination of the components of the wing itself to minimize the mass of the overall solution, and at the same time, it does not consider the aerodynamic performance before and after the rotor tilts and the need for deceleration of the whole machine

Abstract

The invention discloses a flap and rotor wing linked tilting mechanism, which solves problems of lack of flap and rotor wing linkage and aerodynamic force consideration; a bracket is fixed on a wing, two ends of the bracket are respectively and movably connected with a flap keel and a rotor wing assembly arranged on the wing, and the rotor wing assembly comprises a rotor wing motor and a rotor wing motor seat. The rotor wing motor is fixedly arranged on the rotor wing motor seat, and the rotor wing motor seat is movably connected with the bracket. A rotor wing tilting mechanism is connected with the bracket and the rotor wing assembly and used for driving the rotor wing assembly to tilt around the bracket. And a flap linkage mechanism is connected with the rotor wing tilting mechanism and the bracket, and is used for linking the flaps to swing when the rotor wing assembly tilts. When the axis of the rotor wing is in a horizontal state, the flap is in a non-working state, and when the axis of the rotor wing is converted into a vertical state from the horizontal state, flap linkage is changed into lower hem, so that the purposes of linkage of the tilting mechanism and the flap and optimization of aerodynamic layout are achieved.

Description

technical field [0001] The invention relates to the field of tilting multi-rotor aircraft, in particular to a tilting mechanism with flaps and rotors linked. Background technique [0002] Conventional rotorcraft (such as helicopters, multi-rotor drones, etc.) have relatively efficient vertical take-off and landing performance, hovering, low-altitude and low-speed flight, and unique backward and side flight capabilities. Asymmetric, its maximum flight speed is limited by the compressibility of the airflow of the forward blades and the separation of the airflow of the backward blades, so it is difficult to further increase the flight speed. Tilting multi-rotor aircraft has the characteristics of efficient hovering performance, high-speed cruising capability, long range, long endurance, high safety, environmental protection, and low noise. It is a feasible development direction for new configuration rotor aircraft in the future, but The tilting mechanism requires an additional...
