Description
Technical Field
The utility model relates to an aircraft of bionical birds flapping wing flight to specifically relate to a flapping wing aircraft.
Background
With the continuous development of technologies such as mathematics, computers, biology and the like, people gradually find some specific laws of flapping-wing flying creatures. The flapping wing air vehicle has the advantages of easy control, high reliability, good maneuverability, strong concealment, low noise and extremely high flight efficiency, can realize the special effects of vertical takeoff and landing, hovering, front flying, back flying, diving, sharp turning and the like, and has wider application prospect in the military and civil fields.
Although the existing flapping wing air vehicle can achieve better flight and control, the gap between the existing flapping wing air vehicle and the practical application is still certain, so that the existing flapping wing air vehicle cannot be widely applied. Moreover, the flapping wing structure design of the existing flapping wing aircraft is based on the design of a flapping wing controller, so that the innovative design of the flapping wing mechanism of the flapping wing aircraft is few and few, and at present, the flapping wing scheme of the flapping wing mechanism needs to be innovated, so that the problem of the air characteristic of the flapping wing aircraft is solved.
Disclosure of Invention
The utility model aims at: an ornithopter is provided which is capable of optimizing the air characteristics of an ornithopter.
In order to achieve the above purpose, the utility model provides a technical scheme does: the flapping wing aircraft consists of an energy storage motor, an assembly panel, an arc-shaped rack, a gear, a bolt 1, a threaded support rod, a locking nut, an inner section wing, a tension spring, a bolt 2, an outer section wing, a machine head, a machine body and a tail wing. The flapping wing device is characterized in that an energy storage motor provides power to drive a gear to enable a meshed arc-shaped rack to move up and down, an inner section wing with attached flapping wings flaps can flap up and down, and an outer section wing is connected with the inner section wing by a bolt 2 and a tension spring to flap up and down along with the inner section wing.
After the structure is adopted, the utility model has the advantages of as follows: compared with a classic connecting rod transmission mechanism, the transmission mode of the gear rack has more accurate control and smaller space occupation rate.
Preferably, the upper tension spring and the lower tension spring of the inner-section wing and the outer-section wing of the flapping wing aircraft realize the flexibility of the rigid wing. In the process of moving the two arc-shaped racks upwards, the end, far away from the gear, of the inner-section wing flaps downwards flap, the bolt 2 serves as a rotating shaft of the inner-section wing flaps and the outer-section wing flaps to enable the inner-section wing flaps and the outer-section wing flaps to have a relative rotating trend, and the outer-section wing flaps are driven by the tension springs below to downwards move together in the process of downwards flap of the inner-section wing flaps, so that the downwards flap of the two sections of wing flaps is realized, and a larger lifting force is generated; when the energy storage motor rotates reversely, the arc-shaped rack moves downwards, the end, far away from the gear, of the inner section wing swings upwards, the tension spring above drives the outer section wing to move upwards together, at the moment, the tension force of the tension spring above and the tension force of the tension spring below are inconsistent, and the distance below is relatively large, so that the tension force is poor, when the outer section wing swings upwards, the outer section wing has a certain rotation amplitude towards the inner side (the arc-shaped circle center of the outer section wing), so that the area of the two sections of wings in the upward swinging process is reduced, and the received resistance is correspondingly reduced. The ingenious mechanism design improves the air characteristic of the flapping wing air vehicle, and is more in line with the actual bird flying condition.
