Lift enhancement and stability augmentation integrated pneumatic rotor wing

Abstract

The invention discloses a lift enhancement and stability augmentation integrated pneumatic rotor wing which comprises a central shaft, a propeller blade, a quality loop, and a plurality of small wings, wherein the central shaft is arranged in the center of the quality loop, two ends of the propeller blade are respectively and fixedly connected with the central shaft and the quality loop, and the small wings are circumferentially arranged at the outer loop wall of the quality loop. When the rotor wing is arranged in a flow field vertical to the central shaft, incoming flow passes through the small wings and generates lift force and resistance, and under the resistance, the small wings move horizontally along the direction of the incoming flow so as to drive the quality loop to rotate with the strong spinning stability. The quality loop drives the propeller blade and the small wings to rotate, in rotation, the propeller blade generates relatively large lift force, and the small wings also generate relatively large lift force in rotation. The pneumatic rotor wing is driven by wind, provides lift force for an air vehicle in rotation, and enhances the stability without consuming energy of the air vehicle; the pneumatic rotor wing has a simple structure, and is particularly suitable for the small and micro air vehicles.

Description

technical field [0001] The invention relates to a rotor, in particular to a wind-driven rotor integrating lift and stability enhancement, and belongs to the technical field of aviation airfoil applications. Background technique [0002] The existing published technical literature "Analysis of the Current Situation and Development Trend of Micro-rotor Vehicles" (Science and Technology Vision, 2014) discusses the significance of the development of micro-aircraft, and compares the development status at home and abroad, and analyzes the development of micro-aircraft.
