Abstract
The invention provides a kind of balance piece for being used for five leaf rotating plasma culvert type unmanned vehicles, the integration efficiency for causing air-flow using the cooperation of the culvert type aircraft of the balance piece and five vane propellers is improved, so as to reduce the loss to lift.
Description
Technical field
The application is related to a kind of culvert type unmanned vehicle, and in particular to a kind of balance of culvert type unmanned vehicle
Device.
Background technology
In recent years, the production of unmanned vehicle and research and development are progressively risen, the distinctness that unmanned vehicle possesses due to its own
Technical characterstic, military and civilian field be widely used with development at full speed, especially agricultural protection, communication in
After, prevent and reduce natural disasters, weather monitoring, power transmission, survey and draw, take photo by plane, the field tool such as entertain and have a wide range of applications.Unmanned plane includes
Polytype, and culvert type unmanned plane has the flight characteristic of VTOL and hovering, in volume, disguised and flying quality
All there is salient feature, it has also become more type is produced and applied in Small and micro-satellite field.
At present, the production company of culvert type unmanned vehicle is proposed the culvert type unmanned vehicle of Multiple Type successively.
For example, the Cypher unmanned plane during flyings device that Sikorsky companies release is flown using the culvert type of coaxial double-oar culvert type layout
Device；The Honeywell Inc. of famous American is proposed kestrel unmanned vehicles；Singapore is also proposed the culvert type wind of oneself
Fan unmanned plane fantail.Culvert type unmanned vehicle generally mainly includes load cabin, ducted fan system, landing chassis and power
System is constituted.In numerous culvert type unmanned vehicles, culvert type single-blade unmanned vehicle typically all uses the big torsion of rotating speed high
Square engine provides lift, and propeller can produce powerful swirling eddy and moment of torsion, swirling eddy and moment of torsion when engine works
Have a strong impact on direction and the gesture stability of unmanned plane.
Be the influence for offsetting swirling eddy and moment of torsion to the flight control of culvert type unmanned vehicle, traditional culvert type nobody
Aircraft is typically flowed into using radially-arranged 6,8 or the fixed displacement commutator segment of multi-disc to the rotary pneumatic that propeller is produced
Row rectification.Due to the particularity of culvert type unmanned vehicle, changed in floating state, high-speed flight state and flying weight
When, the working speed of engine changes very greatly, its rectification when engine speed is varied widely of fixed displacement commutator segment
Efficiency declines very greatly, very big on flight stability and flight safety influence.Fixed another side effect of displacement commutator segment,
It is exactly quite big lift loss, about loses 1 15 lift.Fixed displacement commutator segment design difficulty in computation is big, shaping
Processed complex needs special precision die, blade to be damaged cannot be repaired, and production and use cost are high.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides one kind for five leaf propeller culvert types nobody
The balance piece of aircraft, it is characterised in that the balance piece is arranged in culvert type unmanned vehicle duct body
Five leaf propellers lower section, has 16 compositions, is connected with the body of culvert type unmanned vehicle by fixture respectively；The nothing
Man-machine balance piece reverse tangent line is presented in duct and is uniformly distributed, and in the centre bit of the leaf propeller of duct middle-range five
The vertical range put is the length of the 1/3 ~ 1/4 of five leaf propeller diameters；The balance piece for unmanned plane is fine carbon
Dimension material.
Beneficial effect：The reverse tangent line distribution balance piece of invention, the swirling eddy that propeller can be produced is converged
Without hindrance derivation is smoothed together, and not only rectification efficiency is high but also without any loss of lift, and the effect of counter balance torque is also very strong.
Reverse tangent line distribution balance piece is made up of the rectangle carbon fiber plate of all-body configuration, is independently mounted in duct.Its advantage is
Simplify housing construction, easy-maintaining replacing, process simple, with low cost.It is of the invention by substantial amounts of experiment, to rectification efficiency
Lifted, the distance by the quantity of the balance piece to five leaf rotating plasma culvert type unmanned planes, distribution mode and with rotating plasma
Integrated, it was found that when the quantity of balancing patch is 16, the reverse equally distributed balance piece of tangent line can optimize spiral
Slurry air-flow produced when rotated so that air-flow can be integrated, it is to avoid influence of the air-flow to flight stability.Enter one
Step, causes that rectification effect is further lifted by adjusting five leaf rotating plasmas with the distance of balancing patch, reduces the loss to lift, phase
Compared with 6 or 8 chips the flat very piece of prevailing torque, its loss of lift is reduced to less than 5%.
Brief description of the drawings
Fig. 1 is the culvert type unmanned vehicle schematic diagram with balance piece.
