Abstract
A kind of special wing, belongs to aircraft technology field, including the leading portion wing, the stage casing wing, the back segment wing, telescopic rod, connector, shaft and transmission device.Fluted in the wing of stage casing, which can store the back segment wing；The rear end at the wing tip position of the stage casing wing and the rear end at the wing tip position of the back segment wing are attached by active connection；Telescopic rod one end is connected to the leading portion wing, and the other end is connected on the back segment wing；Shaft is fixed on the rear portion of the leading portion wing；The leading portion wing is mutually flexibly connected with the stage casing wing by shaft；Transmission device is placed on the wing of stage casing, and transmission device is connected by gear structure with shaft；When controlling transmission device to rotate, transmission device drives shaft to rotate, and the angle of attack of the leading portion wing becomes larger or diminishes；Move when telescopic rod extends, after back segment flapwise and opened in a manner of in sector, the wing area increase of wing.The configuration of the present invention is simple, can change the area and the angle of attack of wing, can obtain different lift thereby using the aircraft of the wing with being adjusted according to service condition.
Description
Technical field
A kind of special wing, belongs to aircraft technology field, more particularly to a kind of special wing.
Background technology
Wing be aircraft awing can configuration again critical piece.Awing purposefully change wing shape
The efficiency of wing can effectively be increased.Wherein, the effect for changing the span and wing area is the most prominent.
The content of the invention
The object of the present invention is to provide a kind of wing that can change wing area.
A kind of special wing, including the leading portion wing, the stage casing wing, the back segment wing, telescopic rod, connector, shaft and transmission device.In
The rear portion of Duan Yi is equipped with groove, which can store the back segment wing；The rear end at the wing tip position of the stage casing wing and the wing tip of the back segment wing
The rear end at position is attached by active connection；Telescopic rod one end is connected to the leading portion wing, and the other end is connected on the back segment wing；
Shaft is fixed on the rear portion of the leading portion wing；The leading portion wing is mutually flexibly connected with the stage casing wing by shaft；Transmission device is placed on the wing of stage casing,
Transmission device is connected by gear structure with shaft；Connector is located at the wing root position of the stage casing wing, winged for wing to be fixed on
On machine fuselage；When controlling transmission device to rotate, transmission device drives shaft to rotate so that the angle of attack of the leading portion wing becomes larger or becomes
It is small；When telescopic rod extends, due to there is active connection, move after back segment flapwise and opened in a manner of in sector, made
Obtain the wing area increase of wing；When telescopic rod is shunk, the part-structure of the back segment wing is retracted into the groove of the leading portion wing.
Preferably, telescopic rod uses electric telescopic rod, hydraulic telescopic rod or manpower telescopic rod.
Preferably, high lift device is equipped with the leading portion wing.
Preferably, it is equipped with aileron at the wing tip position of the stage casing wing.
Preferably, winglet is equipped with the back segment wing.
A kind of special wing of the present invention, it is simple in structure, the area of wing can be changed, can be with being carried out according to service condition
Adjustment obtains different lift thereby using the aircraft of the wing.

Embodiment
The present invention is illustrated below in conjunction with the accompanying drawings：A kind of special wing, including the leading portion wing 1, the stage casing wing 2, back segment
The wing 3, telescopic rod 4, connector 5, shaft 6 and transmission device 7.In stage casing, the rear portion of the wing 2 is equipped with groove 8, after which can store
The section wing 3；The rear end at the wing tip position of the stage casing wing 2 and the rear end at the wing tip position of the back segment wing 3 are attached by active connection；
4 one end of telescopic rod is connected to the leading portion wing 1, and the other end is connected on the back segment wing 3；Telescopic rod 4 uses electric telescopic rod；Shaft 6 is solid
It is scheduled on the rear portion of the leading portion wing 1；The leading portion wing 1 is mutually flexibly connected with the stage casing wing 2 by shaft 6；Transmission device 7 is placed on the stage casing wing 2,
Transmission device 7 is connected by gear structure with shaft 6；Connector 5 is located at the wing root position of the stage casing wing 2, for wing to be fixed
On airframe；When controlling transmission device 7 to rotate, transmission device 7 drives shaft 6 to rotate so that the angle of attack of the leading portion wing 1 becomes
Greatly or diminish；When telescopic rod 4 extends, due to there is active connection, the back segment wing 3 moves in a manner of in sector backward
Open so that the wing area increase of wing；When telescopic rod 4 is shunk, the part-structure of the back segment wing 3 is retracted into the leading portion wing 1
In groove 8.
