Description
Technical field
The invention belongs to a kind of aircraft, is in particular a kind of flapping wing aircraft.
Background technology
Flapping flight have the advantages that mechanical efficiency high, security it is good, can VTOL, noise it is little.At present, known flapping wing
Aircraft mainly by：Flight operation device, flapping wing, dynamical system, transmission system, empennage, flight control system, airframe structure body composition.
Dynamical system can be divided into：Internal combustion engine class, electric machinery, Electromagnetic muscle class and polymer muscles class.Flapping wing can be divided into class dragonfly not
Flexible wing and the flexible wing of class bird.During flight, power is produced by dynamical system, Jing transmission systems make flapping wing flap and rotate
So as to produce lift and pulling force, aircraft flight is made；Adjust flap frequency and the rotation direction of flapping wing by flight control system simultaneously,
To control the speed and flight attitude of aircraft.Flapping wing need to produce lift upwards, its bat if flapping wing aircraft hovering is aerial
Beat process be：Flapping wing is patted downwards in the stroke of minimum point from peak, because the active force of air produces lift upwards；When
Flapping wing can produce downward active force from the active force that minimum point is returned in peak stroke upwards because of air；So downward
Need to increase flapping wing face journey in beating and produce bigger lift, need the area for reducing flapping wing to produce in patting upwards less downward
Active force.At present flapping wing aircraft reduces the mode of flapping wing area in upward stroke and is mainly rotation so that flapping wing with
Upwards the projected area on the perpendicular face of the direction of motion reduces.It is this by rotating overall flapping wing, so as to reduce flapping wing with to
The mode of the projected area on the perpendicular face of the upper direction of motion, process is slow, reduces limited area.
The content of the invention
In order to solve tradition by rotating overall flapping wing, so as to reduce flapping wing with the perpendicular face of the direction of motion on projection
The mode of area, process is slow, reduces the problem of limited area.The present invention provides a kind of flapping wing, and the flapping wing can be upper with flapping wing
Lower beating motion is engaged；Rapidly increase the area of flapping wing when needing to increase flapping wing area, needing to reduce flapping wing area
When, rapidly reduce the area of flapping wing itself；Rather than traditional flapping wing reduces flapping wing perpendicular with the direction of motion by rotating
Projected area on face.
The technical solution adopted for the present invention to solve the technical problems is：Flapping wing is divided into some fritters, fritter and flapping wing
Connection；Each fritter is characterized in that can be stretched by the frame priming of fritter, change fritter area；Or can be along the axle being connected with flapping wing
Rotate, fritter is being changed with the projected area on the perpendicular face in flapping motion direction by rotating.In the motion process of flapping wing
In, by transmission device, the frame for making slidable fritter stretches, so as to change the area of each fritter, so as to change entirety
The size of flapping wing；Or the fritter that each is rotated is rotated along the axle being connected with flapping wing by transmission device, so as to change
Fritter with the perpendicular face in flapping motion direction on projected area, so as to change the size of overall flapping wing.Fly in flapping wing
In the flight course of row device, the change of flapping wing area is controlled by flight control system, coordinate the beating frequency with flapping wing and direction.
The invention has the beneficial effects as follows, make flapping wing quickly to reduce and increase the face of flapping wing during flight is patted
Product, so that flapping wing aircraft has higher Energy Efficiency Ratio, produces bigger lift thrust.
