Description
Technical field
This utility model is related to aviation aircraft design field, more particularly, to a kind of winglet of wing.
Background technology
When air-flow is through two surfaces up and down of aircraft wing, produced draught head can produce upwards on wing
Lift, when this power is more than the weight of aircraft, aircraft just can fly on high.But at this moment wing lower surface pressure is larger
Air-flow, have part flow to the less upper surface of pressure at wingtip, and therefore produce vortex, when aircraft fly faster, produced
Raw vortex is also stronger, so can increase the consumption of resistance during flight and increasing fuel.Reduce the appearance of this vortex, existing
A kind of method having technology is using more elongated wing, but too long of wing can make aircraft cause in more small-sized airport
Inconvenience, for example, cannot use some air bridges etc..So, just occur in that the design of winglet, it can be by changing wingtip
Neighbouring air-flow is thus reduce the intensity of vortex, and the component that its angle also can produce upwardly and forwardly simultaneously is winged to increase
The lift of machine and thrust.Although winglet can effectively reduce the resistance and fuel consumption during flight, in short distance course line
Above it does not compensate for the consumption of fuel for the extra heavy burden that aircraft brings.So being used on the aircraft in short distance course line not at some
Winglet can be installed.For some regional airports, short distance course line is typically chosen does not install winglet, long-range course line fly
Machine wing is then to select to install winglet, and sometimes flight is nervous, and short distance airline aircraft may be unsuitable on long-range course line
Navigation, because the shape and structure of wing affects and makes waste of fuel and obstruction power is big etc., if short distance course line and long-range course line are equal
There is flight, be likely to result in the wasting of resources and take up room larger.Accordingly, it would be desirable to a kind of structure of wing, can navigate in short distance
Travel on line and also can travel on long-range course line, thus not affecting the flight of aircraft.
Utility model content
In view of this, this utility model provides a kind of winglet of wing, solves the non-rotatable receipts of winglet
The problem received.
The technological means that this utility model adopts are as follows：A kind of winglet of wing is little including wing-body and wingtip
The wing, also includes connector, and described wing-body is connected with described winglet by connector, and described connector includes fixing
Seat, rotation dish and vertical shaft, described rotation dish and described fixed seat integrally connected, described vertical shaft is connected with described rotation dish, described
Rotation dish is provided with support, and described fixed seat is arranged on the lower section of described wing-body, described vertical shaft and described winglet
Side connects, and the rotational angle of described rotation dish is 0～130 °.
Preferably, described vertical shaft is embedded in described rotation dish, is flexibly connected with described rotation dish.
Preferably, described fixed seat and described wing-body chain connection.
Preferably, described winglet is provided with warning lamp, and described warning lamp is used for sign.
Preferably, described winglet is also equipped with discharging rod.
Using a kind of winglet of wing provided by the utility model, by connector, winglet can be received
To wing-body, it is suitable to short distance course line, reduce the consumption of fuel and the stability ensureing aircraft；Wing is made by connector
Body becomes certain inclination angle with winglet, is suitable to long-range course line so that winglet can weaken vortex, reduces resistance, thus
Reach the purpose of fuel-economizing.
Brief description
Fig. 1 is a kind of structural representation of the winglet of wing of this utility model；
Fig. 2 is a kind of folding schematic diagram of the winglet of wing of this utility model.
In figure：1 wing-body, 2 winglets, 21 warning lamps, 22 discharging rod, 3 connectors, 31 fixed seats, 32 rotation dish,
33 vertical shafts, 321 supports.
Specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example is served only for explaining this practicality
New, it is not intended to limit scope of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, a kind of winglet of wing, including wing-body 1 and winglet 2, also includes connecting
Part 3, described wing-body 1 is connected with described winglet 2 by connector 3.Described connector 3 includes fixed seat 31, rotates
Disk 32 and vertical shaft 33, described rotation dish 32 and described fixed seat 31 integrally connected, described vertical shaft 33 is embedded in described rotation dish 32
Interior, it is flexibly connected with described rotation dish 32, described fixed seat 31 and described wing-body 1 chain connection.In described rotation dish 32
It is provided with support 321, described support 321 is used for fixing the position of described vertical shaft 33.Described fixed seat 31 is arranged on described wing originally
The lower section of body 1, described vertical shaft 33 is connected with the side of described winglet 2, and the rotational angle of described rotation dish is 0～130 °,
When the rotational angle of described rotation dish 32 is 0 °, now described winglet 2 is placed in above described wing-body 1, is suitable to short
The flight in journey course line.Described winglet 2 is provided with warning lamp 21, and described warning lamp 21 is navigation lights, for sign, navigates
Portable lighter is used for distinguishing that flying object is aircraft and the effect of instruction heading and mark.It is also equipped with keeping away on described winglet 2
Thunder pin 22, aircraft moves in atmosphere, due to the friction of air and other impurity, will produce electrostatic charge on airframe,
The releasable energy of a charge of described discharging rod 22.When the rotational angle of described rotation dish is 120 °, now described winglet 2 with
The joint angle of described wing-body 1 is 120 °, is suitable to long-range course line, described winglet 2 improves wing aerodynamic performance.Due to rising
The generation of power can produce induced drag simultaneously, and the size of induced drag depends on along the lift distribution of spanwise and its leads to
