The embodiment of the invention provides a flapping wing system and an ornithopter. An inner section wing is hinged to a machine body. A drive mechanism connected to the machine body is connected withthe inner section wing and drives the inner section wing to flap. A first wing beam is hinged to the inner section wing, and a second wing beam is hinged to a second connecting rod mechanism. A firstconnecting rod mechanism is connected between the drive mechanism and the first wing beam so that the drive mechanism and the inner section wing can be used for driving the first wing beam to flap. The second connecting rod mechanism is connected between the drive mechanism and the second wing beam, and accordingly the drive mechanism and the inner section wing are used for driving the second wing beam to flap. The swinging amplitude of the second wing beam is different from the swinging amplitude of the first wing beam. Through the arrangement of the second wing beam, the second wing beam isconnected with the drive mechanism and the inner section wing through the first connecting rod mechanism and the second connecting rod mechanism, and the drive mechanism and the inner section wing are used for driving the second wing beam to flap; and meanwhile, the second wing beam and the first wing beam are different in swinging amplitude, and the attack angle of an outer section wing is changed through active torsion control.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of aircraft control, and in particular to an orchid wing system and an orthopedic aircraft. Background technique [0002] The orthopter, also known as the thopter, refers to a heavier-than-air aircraft whose wings can flap up and down like the wings of birds and insects. As the main structure of the flapping wing, it is designed and manufactured based on the principle of bionics. The flapping wing generates lift and forward propulsion, so that the flapping wing can take off, land, accelerate, decelerate, jump sharply, and turn sharply. , hovering, inverted flight, dive and lift and other flight actions. Compared with fixed-wing and rotary-wing aircraft, the orthopter has stronger low consumption, flexibility and maneuverability, and is a research hotspot in this field. [0003] Birds evolved from reptiles. The wing of the bird's forearm corresponding to the forearm of reptiles not onl...
