Estimate, harass, luring, (sea) attack, target simulation and early warning etc. over the ground.In civil field, it can be used for geodesic survey, meteorology
Observation, urban environment detection, earth resource exploration and forest fire protection, plant protection field etc..Therefore it is detectable, search for and track ground
The small drone of target complies with the growth requirement of military and civilian, has broad application prospects, especially in military field, nothing
It is man-machine that oneself has been obtained large-scale development, and the trend of substituted someone's fighter plane.However the rotor of existing rotor wing unmanned aerial vehicle
Unreasonable structural design causes flight efficiency low, and air drag is big, and power consumption is more, it is therefore desirable to improve.
Utility model content
There is provided utility model aims to solve above-mentioned technical problem it is a kind of can improve flight efficiency nobody
Machine rotor.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of unmanned plane rotor, including two rotor bodies, two rotor bodies pass through electric with rotor after rotor folder connection
The output shaft of machine driving box is connected, and two rotor bodies are in the same size, and structure is identical, each rotor body include with
In the interconnecting piece being cooperatively connected with rotor folder and the alar part to connect with the interconnecting piece；The alar part is in length direction from outside
Free end gradually increases to form the wide cone-shaped in the narrow inside in outside to the width of interconnecting piece, and the alar part in width direction from
One side is gradually increased to after certain position again with one section big smooth cambered surface through one section of small smooth arc to the thickness of another side
Thickness is reduced and transits to another side to form streamline surface by face.
The arc length of the big smooth cambered surface is 3-4 times of arc length of small smooth cambered surface.
The interconnecting piece is sloped downwardly a lower angle, and the interconnecting piece to output shaft from the junction with the alar part
Width direction side on two sides be respectively provided with an outside inclined portion.
The interconnecting piece is gradually reduced to form conical surface shape structure from the junction with the alar part to the width of output shaft side.
The utility model by include two rotor bodies, two rotor bodies by rotor folder connect after with rotor motor
The output shaft of driving box is connected, and two rotor bodies are in the same size, and structure is identical, and each rotor body includes and is used for
The interconnecting piece being cooperatively connected with rotor folder and the alar part to connect with the interconnecting piece；The alar part in length direction from outside from
Gradually increased from end to the width of interconnecting piece and form the wide cone-shaped in the narrow inside in outside, and the alar part in width direction from one
Side is gradually increased to after certain position again with one section big smooth cambered surface through one section small smooth cambered surface to the thickness of another side
Thickness is reduced and transits to another side to form streamline surface, the rotor structure of optimization improves rotor lift efficiency,
Running resistance is reduced, the loading capacity of multi-rotor unmanned aerial vehicle is greatly improved, effectively improves flight efficiency.
Detailed description of the invention
Fig. 1 is the schematic side view from outer free end for the unmanned plane rotor connecting with rotor motor driving box；
Fig. 2 show the schematic top plan view for the unmanned plane rotor connecting with rotor motor driving box；
Fig. 3 is the schematic diagram of the streamline surface of unmanned plane rotor.
Specific embodiment
In the following, being further described in conjunction with substantive distinguishing features and advantage of the example to the utility model, but this is practical new
Type is not limited to listed embodiment.
Join as shown in figure 1 to 3, a kind of unmanned plane rotor, including the first rotor body 10, the second rotor body 20, two rotations
Wing body after 30 connection of rotor folder with the output shaft 40 of rotor motor driving box 50 by being connected, two rotor body sizes one
Cause, structure is identical, each rotor body include with for rotor folder be cooperatively connected interconnecting piece with 17 and with the connection
The alar part that portion 17 connects；The alar part is at length direction is from outer free end 11 to the link position 12 of interconnecting piece and alar part
Width gradually increases to form the wide cone-shaped in the narrow inside in outside, and the alar part in width direction from a side 13 to the other side
The thickness at end 14 is gradually increased to after certain position again reduce thickness by one section small smooth cambered surface with one section big smooth cambered surface
And another side is transitted to form streamline surface.
Preferably, the arc length of the big smooth cambered surface is 3-4 times of arc length of small smooth cambered surface.
The interconnecting piece is sloped downwardly a lower angle, and the interconnecting piece to output shaft from the junction with the alar part
Width direction side on two sides be respectively provided with an outside inclined portion, the first outside inclined portion 16, second tilts outward
Portion 15.
Wherein, in the utility model, the interconnecting piece from the junction of the alar part to the width of output shaft side gradually
