The contriver finds, although above-mentioned aircraft has realized hovering flight, because its flapping wing is only single-degree-of-freedom level fluttering, relies on the lift that the chord direction torsional deformation of flapping wing provides (equal to the flapping wing that horizontal flight provides Thrust) is small, so the take-off mass of DELFLY and other aircraft is very small, the load carried is limited, and it is not easy to disassemble and carry

Embodiment 1
[0038] A typical embodiment of the present invention: as Figure 1-6 Shown, a hovering flapping wing aircraft.
[0039] Such as figure 1 As shown, it includes a base body, a drive mechanism, a wing plate and an empennage. The drive mechanism and the wing plate together form a flapping wing mechanism. Driven by the drive mechanism, the board can swing back and forth, thereby achieving lift, driving the aircraft as a whole to rise or hover, and the shape of the aircraft can be adjusted through the tail.
[0040] Of course, it can be understood that the wing plate only represents the wing composition of the aircraft, and does not limit the shape and size of the wing plate. According to the required lift requirements and other requirements, the shape, structure, The size can be configured as needed, as long as the lift can be obtained when the wing board swings back and forth.
[0041] In this embodiment, no limitation is imposed on the structure of the empennage, as long as th...
Embodiment 2
[0060] In another typical embodiment of the present invention, such as figure 2 , Figure 7 and Figure 8 As shown, a hovering flapping wing robot.
[0061] It includes a base body on which a flapping wing mechanism is installed, and the flapping wing mechanism includes a driving mechanism and a wing plate, and the wing plate includes opposite first and second surfaces, and the first surface faces the first side of the wing plate. When moving in one direction, lift force can be generated under the action of air, and the second surface can generate lift force under the action of air when the wing plate moves in the second direction. movement; the base body is provided with a chute, the drive mechanism includes a motor, a crank, a connecting rod and a pulley, the outside of the pulley is connected with a docking block, and the docking block is installed on the pulley through a bearing, and the motor The output end of the crank is connected to one end of the crank, the other ...

Abstract
The invention discloses a hoverable flapping-wing aircraft which comprises a base body, wherein a flapping-wing mechanism is mounted on the base body. The flapping-wing mechanism includes a driving mechanism and a wing plate. The wing plate comprises a first side and a second side, wherein the first side and the second side are opposite. The first side can generate lift force under the action of air when the wing plate moves in the first direction, the second side can generate lift force under the action of the air when the wing plate moves in the second direction, and the driving mechanism drives the wing plate to alternately move in the first direction and the second direction. The lift force is continuously obtained through the movement of the wing plate in the two directions, so that the stable hovering function is realized, and the shaking phenomena caused by the fact that a traditional flapping-wing aircraft gains the lift force only by moving in one direction is avoided.
Description
technical field [0001] The invention belongs to the field of flapping-wing aircraft, in particular to a hovering flapping-wing aircraft. Background technique [0002] Compared with other types of aircraft, the flapping wing aircraft has a major technical advantage in that it can realize hovering flight. Aircraft with hovering function can realize vertical take-off and landing, hovering, retreating and other motion modes. Floor monitoring, etc. provide greater convenience. [0003] At present, the miniature flapping-wing aircraft that can realize hovering flight mainly include DELFLY developed by Delft University in the Netherlands and Mentor developed by the University of Toronto in Canada. This type of aircraft mainly provides the lift required for flight through the horizontal flapping of a pair or two pairs of flapping wings on the top of the fuselage, and uses the cross-shaped rudder surface at the lower end of the fuselage to control the flight direction and attitude. ...
