Abstract
A kind of folded wing, belongs to aircraft technology field, including telescopic rod, folding rib, flexible covering, draw off gear and connector.Connector is used to be attached with airframe；Folding on rib has the small rib of polylith, and the every piece small mutual upper end of rib is connected with upper end, and lower end is connected with lower end, and rib is entirely folded after expansion and seems undulate；Aperture is equipped with small rib, rib is folded and is serially connected in by aperture on telescopic rod；Draw off gear is fixed on connector；When controlling telescopic rod elongation, under the drive of telescopic rod, rib expansion is folded, while the flexible covering in rolled condition can also be unfolded and wrap the folding rib after expansion by draw off gear；A kind of folded wing of the present invention, it is simple in structure, wingspan length can be changed, the shape of the cross section of wing changes so that the aspect ratio of wing changes, so that obtaining different lift using the aircraft of the wing.
Description
Technical field
A kind of folded wing, belongs to aircraft 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 folded wing, including telescopic rod, folding rib, flexible covering, draw off gear and connector.Telescopic rod is described
The supporting member of wing, can carry out stretching motion；Connector is used to be attached with airframe；Folding on rib has the polylith small
Rib, the every piece small mutual upper end of rib are connected with upper end, and lower end is connected with lower end, and rib is entirely folded after expansion and is seen
Get up undulate；Aperture is equipped with these small ribs, rib is folded and is serially connected in by aperture on telescopic rod；Telescopic rod
Head end be connected on connector, end be connected to fold rib the small rib of last block on；Fold first piece of winglet of rib
Rib is mutually fixedly connected on connector；Flexible covering is divided into two parts, and a part, which is wrapped in, to be folded on rib, another part retracting
In draw off gear；Draw off gear is fixed on connector, and draw off gear can be furled and be unfolded to flexible covering；Work as control
When telescopic rod extends, under the drive of telescopic rod, folding rib is also unfolded, while draw off gear can will also be in rolled condition
Flexible covering be unfolded and wrap expansion after folding rib；The length of wing is seen on the whole, wing length is different,
The cross-sectional area of wing is also different so that the aspect ratio using the aircraft of the wing is also different, so that what wing obtained
Lift is different.
The quantity of telescopic rod can also use two or three or four.
Winglet is equipped with wing tip position, easy to reduce the appearance of tip vortex, improves the efficiency of wing.
A kind of folded wing of the present invention, it is simple in structure, wingspan length can be changed, the shape of the cross section of wing occurs
Change 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 wing removes schematic top plan view after flexible covering；Fig. 3
It is to fold rib structure schematic diagram.
In figure, 1- telescopic rods, 2- folds rib, and 3- flexible coverings, 4- draw off gears, 5- connectors, the small ribs of 6-, 7- is small
Hole.
Embodiment
The present invention is illustrated below in conjunction with the accompanying drawings：A kind of folded wing, including telescopic rod 1, fold rib 2, soft
Property covering 3, draw off gear 4 and connector 5.Telescopic rod 1 is the supporting member of the wing, can carry out stretching motion；Connector 5 is used
It is attached in airframe；Folding on rib 2 has the small rib 6 of polylith, every piece small 6 mutual upper end of rib and upper end phase
Connection, lower end are connected with lower end, and rib 2 is entirely folded after expansion and seems undulate；It is all provided with these small ribs 6
There is aperture 7, fold rib 2 and be serially connected in by aperture 7 on telescopic rod 1；The head end of telescopic rod 1 is connected on connector 5, end connection
On the small rib 6 of last block for folding rib 2；First piece small rib, 6 phase for folding rib 2 is fixedly connected on connector 5；It is soft
Property covering 3 be divided to for two parts, a part, which is wrapped in, to be folded on rib 2, and another part is furled in draw off gear 4；Folding and unfolding fills
Put 4 to be fixed on connector 5, draw off gear 4 can be furled and be unfolded to flexible covering 3；When controlling telescopic rod 1 to extend,
Under the drive of telescopic rod 1, folding rib 2 is also unfolded, while draw off gear 4 also can be by the flexible covering in rolled condition
3 are unfolded and wrap the folding rib 2 after expansion；The length of wing is seen on the whole, and wing length is different, wing
Cross-sectional area 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.
