Abstract
A kind of wing that can be folded, belongs to vehicle technology field, including the fixed part wing and the folded portion wing；One end of fixed part is connected with the fuselage of aircraft, and the other end is connected to the folded portion wing；The fixed part wing is similar to conventional airfoil, and the fixed part wing is equipped with aileron；The folded portion wing includes telescopic rod, small rib, flexible covering and draw off gear；The folded portion wing carries out stretching motion, and the length of wing, folded portion chord degree is different, and the cross-sectional area of the folded portion wing is also different so that the aspect ratio using the aircraft of the wing is also different, so that the lift that wing obtains is different.A kind of wing that can be folded of the present invention, it is simple in structure, wingspan length can be changed, so that obtaining different lift using the aircraft of the wing.
Description
Technical field
A kind of wing that can be folded, belongs to vehicle technology field, more particularly to a kind of 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.
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 wing that can be folded, including the fixed part wing and the folded portion wing；One end of the fixed part wing and aircraft
Fuselage be connected, the other end is connected to the folded portion wing；The fixed part wing is similar to conventional airfoil, and the fixed part wing is equipped with pair
The wing；The folded portion wing can stretch；The folded portion wing includes telescopic rod, small rib, flexible covering and draw off gear；Winglet
Rib has polylith, and the every piece small mutual upper end of rib is connected with upper end, and lower end is connected with lower end, seems to be in ripple after expansion
Shape wave；Aperture is equipped with small rib, small rib is serially connected on telescopic rod by aperture；The head end of telescopic rod is connected to solid
Determine on the wing of part, end is connected on the small rib of last block for folding rib；Flexible covering is divided into two parts, part bag
It is rolled on the folded portion wing, another part is furled in draw off gear；Draw off gear is placed in the fixed part wing and the folded portion wing
Between connecting portion on, draw off gear can be furled and be unfolded to flexible covering；When controlling telescopic rod elongation, stretching
Under the drive of contracting bar, the folded portion wing is unfolded, while draw off gear also can be by the flexible covering expansion in rolled condition simultaneously
Wrap the folded portion wing after expansion；The length of wing is seen on the whole, and folded portion chord degree is different, folded portion
The cross-sectional area of the wing is also different so that the aspect ratio using the aircraft of the wing is also different, so that the lift that wing obtains
It is different.
The quantity of telescopic rod can also use two or three or four.
Telescopic rod uses electric telescopic rod, hydraulic telescopic rod or manpower telescopic rod.
A kind of wing that can be folded of the present invention, it is simple in structure, wingspan length, the shape of the cross section of wing can be changed
Shape changes so that the aspect ratio of wing changes, so that obtaining different lift using the aircraft of the wing.
Brief description of the drawings
Fig. 1 is the wing structure schematic perspective view；Fig. 2 is that the folded portion wing removes structure diagram after flexible covering；
Fig. 3 is folded portion wing structure schematic diagram；Fig. 4 is small rib structure schematic diagram.
In figure, the 1- fixed part wings, the 2- folded portion wings, 3- ailerons, 4- telescopic rods, the small ribs of 5-, 6- flexible coverings, 7-

Embodiment
The present invention is illustrated below in conjunction with the accompanying drawings：A kind of wing that can be folded, including the fixed part wing 1 and folding
The folded part wing 2；One end of the fixed part wing 1 is connected with the fuselage of aircraft, and the other end is connected to the folded portion wing 2；Fixed part
The wing 1 is similar to conventional airfoil, and the fixed part wing 1 is equipped with aileron 3；The folded portion wing 2 can stretch；The folded portion wing 2
Including telescopic rod 4, small rib 5, flexible covering 6 and draw off gear 7；Small rib 5 has a polylith, every piece small rib 5 between each other on
End is connected with upper end, and lower end is connected with lower end, seems undulate after expansion；Aperture is equipped with small rib 5
8, small rib 5 is serially connected on telescopic rod 4 by aperture 8；The head end of telescopic rod 4 is connected on the fixed part wing 1, and end is connected to
On the small rib 5 of last block for folding rib；Telescopic rod 4 uses electric telescopic rod；Flexible covering 6 is divided to for two parts, one
Subpackage is rolled on the folded portion wing 2, and another part is furled in draw off gear 7；Draw off gear 7 is placed in the fixed part wing 1 and folding
On connecting portion between the folded part wing 2, draw off gear 7 can be furled and be unfolded to flexible covering 6；When control telescopic rod
During 4 elongation, under the drive of telescopic rod 4, the folded portion wing 2 is unfolded, while draw off gear 7 also can be by rolled condition
Flexible covering 6 is unfolded and wraps the folded portion wing 2 after expansion；The length of wing, the folded portion wing 2 are seen on the whole
Length is different, and the cross-sectional area of the folded portion wing 2 is also different so that and the aspect ratio using the aircraft of the wing is also different, so that
So that the lift that wing obtains is different.
