Abstract
A kind of Variable Geometry Wing, belongs to aircraft technology field, including the leading portion wing, the back segment wing, the first telescopic rod, the second telescopic rod and connector.Fluted in the leading portion wing, which can accommodate the part-structure of the back segment wing；First telescopic rod one end is connected to the wing root position of the leading portion wing, and the other end is connected to the wing root position of the back segment wing；Second telescopic rod one end is connected to the wing tip position of the leading portion wing, and the other end is connected to the wing tip position of the back segment wing；Connector is located at the wing root position of the leading portion wing, for wing to be fixed on airframe；When the first telescopic rod and the second telescopic rod extend, the back segment wing slides rearwardly out in the groove of the leading portion wing, and the back segment wing does not skid off from groove completely so that the wing area increase of wing.The configuration of the present invention is simple, can change the area 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 Variable Geometry 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.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 Variable Geometry Wing, including the leading portion wing, the back segment wing, the first telescopic rod, the second telescopic rod and connector；In the leading portion wing
Fluted, which can accommodate the part-structure of the back segment wing so that the back segment wing has the space slided in groove；First is flexible
Bar one end is connected to the wing root position of the leading portion wing, and the other end is connected to the wing root position of the back segment wing；Second telescopic rod one end connects
At the wing tip position of the leading portion wing, the other end is connected to the wing tip position of the back segment wing；Connector is located at the wing root position of the leading portion wing, is used for
Wing is fixed on airframe；When the first telescopic rod and the second telescopic rod extend, the back segment wing in the groove of the leading portion wing
Slide rearwardly out, the back segment wing does not skid off from groove completely so that the wing area increase of wing；Stretched in the first telescopic rod and second
When contracting bar is shunk, the part-structure of the back segment wing is slided into the groove of the leading portion wing so that the wing area of wing reduces.
Preferably, the first telescopic rod and the second Telescopic rod structure are identical, they are using electric telescopic rod, hydraulic telescopic rod
Or manpower telescopic rod.
Preferably, the wing tip position of the leading portion wing is provided with winglet.
Preferably, it is provided with aileron on the back segment wing.
A kind of Variable Geometry 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.
Brief description of the drawings
Fig. 1 is the wing structure schematic diagram；Fig. 2 is leading portion wing structure schematic diagram.
In figure, the 1- leading portion wings, the 2- back segment wings, the first telescopic rods of 3-, the second telescopic rods of 4-, 5- connectors, 6- grooves.
Embodiment
The present invention is illustrated below in conjunction with the accompanying drawings：A kind of Variable Geometry Wing, including the leading portion wing 1, the back segment wing 2, first
Telescopic rod 3, the second telescopic rod 4 and connector 5；Fluted 6 in the leading portion wing 1, which can accommodate the part knot of the back segment wing 2
Structure so that the back segment wing 2 has the space slided in groove 6；First telescopic rod, 3 one end is connected to the wing root portion inside the leading portion wing 1
The front end of position, the other end are connected to the front end at the wing root position outside the back segment wing 2；Second telescopic rod, 4 one end is connected to the leading portion wing 1
The front end at internal wing tip position, the other end are connected to the front end at the wing tip position outside the back segment wing 2；First telescopic rod 3 and
Two telescopic rods, 4 structure is identical, they use electric telescopic rod；Connector 5 is located at the wing root position of the leading portion wing 1, for by wing
It is fixed on airframe；The wing tip position of the leading portion wing 1 is provided with winglet, and winglet can reduce going out for tip vortex
It is existing；Aileron is provided with the back segment wing 2, control aileron enables to the aircraft for assembling the wing to carry out；When 3 He of the first telescopic rod
When second telescopic rod 4 extends, the back segment wing 2 stretches out backward in the groove 6 of the leading portion wing 1, and the back segment wing 2 is sliding not completely from groove 6
Go out so that the wing area increase of wing；When the first telescopic rod 3 and the second telescopic rod 4 are shunk, the part-structure of the back segment wing 2
Slide into the groove 6 of the leading portion wing 1 so that the wing area of wing reduces.
