Ornithopter provided with three-degree-of-freedom wings

Abstract

The invention relates to an ornithopter provided with three-degree-of-freedom wings, belonging to the field of bionic ornithopters. The ornithopter comprises a left front regulation and control mechanism and a right front regulation and control mechanism as well as a left rear regulation and control mechanism and a right rear regulation and control mechanism which are respectively distributed at the left side and the right side of a fuselage in a way of being symmetrical in pairs and can move independently. The ornithopter can closely imitate the three movements such as flapping, turning around and sweeping front and back of wings of a flying bird by means of mutual cooperation of the front regulation and control mechanisms and the rear regulation and control mechanisms, so that enough thrust force and lift force are provided for the ornithopter. The ornithopter is flexible, and the flight efficiency is high; if being provided with equipment such as image transmission equipment, the ornithopter plays a significant role in the fields such as aerial photography, geographic survey, traffic duty, military investigation as well as emergency rescue and disaster relief.

Description

Technical field: [0001] The invention belongs to the technical field of aircraft, in particular to a bionic flapping-wing aircraft. Background technique: [0002] Flapping-wing MAV is a new concept aircraft that imitates birds or insects. Compared with rotor and fixed-wing MAVs, it has natural advantages in terms of lift, speed, miniaturization, flight flexibility, and visual concealment. In the existing flapping-wing aircraft, the design of the flight drive mechanism is mostly single-degree-of-freedom flapping up and down, with relatively low flexibility, large instability, low flight efficiency, and large energy consumption. In the real flight process of birds, the flapping of wings performs complex up and down flapping, twisting and forward and backward sweeping movements in three-dimensional space, and it is difficult for flapping wing aircraft to fully simulate. [0003] Through the long-term observation of the bird's wing movement, the flapping-wing aircraft has desig...
