Technical field
The utility model relates to unmanned plane field, in particular to a kind of SUAV (small unmanned aerial vehicle) Ducted propeller.
Background technology
The blade of existing composite material duct within seven leaves is all overall blade, more than seven leaves because unitary mould design becomes very complicated, so be all designed to combine blade, simultaneously due to the complexity of unitary mould, duct body also adopts array configuration, is all first divided into duct housing, guides, motor fixing seat three part, then assemble on special fixture.Blade is that single blade produced by mould, then is bonded on independent aluminum oar dish.Multi-part combination Problems existing: 1, there is assembly error problem; 2, the blade intensity of bonding forming is not as overall blade, in order to ensure bind strength, just bonding plane must be done greatly, adding structural weight; 3, bonding uncertain factor is many, and environment temperature and humidity and glue quantity all can impact bonding quality, and reliability reduces; 4, the Ducted propeller running power of bonding forming is restricted.
Because existing composite material duct is in precision, intensity, reliability and running power aspect are all difficult to the requirement reaching unmanned plane, and domestic SUAV (small unmanned aerial vehicle) generally adopts driving engine to add the propelling unit of separate propellers as SUAV (small unmanned aerial vehicle).But screw propeller propelling itself has again a lot of weak point: the screw propeller 1, exposed is carried at aircraft, landing has damage often, there is tiny flaw in the screw propeller damaged, the vibrations caused when High Rotation Speed probably cause aircraft accident, the safety problem that the screw propeller fragment that High Rotation Speed flies out is serious especially.In parachuting recovery system, screw propeller can be suspended to parachute line often, causes chute failure and accidents caused.2, isolated propeller blade can make the air-flow of surrounding also produce rotary motion when rotated, causes race rotation to lose.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of easy to assembly, unmanned plane that reliability is high.
Therefore, the technical solution of the utility model is as follows:
A kind of SUAV (small unmanned aerial vehicle) Ducted propeller, multiple blade, oar dish, duct housing, motor fixing seat, guides, motor shaft, motor stator and rotor, wherein:

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As shown in Figures 1 to 5, according to the SUAV (small unmanned aerial vehicle) Ducted propeller of embodiment of the present utility model, multiple blade 1, oar dish 2, duct housing 4, motor fixing seat 6, guides 5, motor shaft 7, motor stator 8 and rotor 9, wherein:
Multiple described blade 1 is uniformly distributed around institute's oar dish 2, and described blade 1 is one-body molded with described oar dish 2;
Described motor fixing seat 6 is arranged in described duct housing 4 by described guides 5, and described motor fixing seat 6, described guides 5 with and described duct housing 4 one-body molded;
Described rotor 9 is connected to described motor shaft 7, described motor shaft 7 is successively through described motor stator 8, described motor fixing seat 6 and described oar dish 2, described motor stator 8 is fixedly connected with described motor fixing seat 6, and described blade 1 is positioned at described duct housing 4.
Carbon fiber composite material is utilized to manufacture the utility model Ducted propeller.Carbon fiber density is low, and modulus is large, makes blade have very large stiffness-to-density ratio, and trembling when can reduce High Rotation Speed, increases propulsion coefficient.
Wherein, oar dish 2 is arranged on motor shaft 7 by motor axis hole 11.
In this technical scheme, by blade 1 and oar dish 2, integrally time processing is shaping, by duct housing 4, guides 5 and motor fixing seat 6, integrally time processing is shaping, when using carbon fiber composite material, the assembly error problem existed in traditional carbon fibres composite material Ducted propeller can be eliminated, intensity and the reliability of Ducted propeller while reducing structural weight, can be improved.
Ducted propeller has been contained in duct housing 4 li culvert channel blade 1, because blade wing tip 3 wraps up by duct, and use safety.Utilize the one-time formed blade of carbon fiber composite material 1 and oar dish 2 to have very high rigidity and precision, it is very little that the spacing between blade wing tip 3 and duct housing 4 can be done, and air-flow cannot walk around wing tip 3, induced drag is reduced, thus efficiency is higher.Under same consumption of power, the combination ducted fan of the more same diameter of one-time formed ducted fan and separate propellers, can produce larger propulsive force.Guides 5 machine-shaping together with duct housing 4, has very high positioning precision, compared with bonding combined guided device, more effectively can change air current flow direction to make air velocity vector and axis being parallel, reduces the slip-stream loss caused by isolated blade rotation.
While the power system compared with conventional small unmanned plane has higher safety and efficiency, than existing carbon fiber composite material duct propulsion system, there is better structural strength and aerodynamic characteristic.
