Description
Technical field
This utility model is related to airmanship field, more particularly, to a kind of miniature ducted fan aircraft.
Background technology
Coaxial double-rotary wing technology：Coaxial double-rotor helicopter have two pairs around same theory axis a positive and a negative rotate it is upper
Lower rotor, due to steering conversely, the moment of torsion that two secondary rotors are produced mutually is balanced under steady state of flight, by upper and lower
Rotor always produces the achievable directional control of uneven moment of torsion away from differential, and coaxial double-rotary wing, in helicopter flight, is both lifting surface
Be again vertically and horizontally, the control surface in course.It is used for balancing rotor torque using coaxial double-rotary wing, is not required to tail-rotor.In structure, due to
Using two secondary rotors, compared with the single-rotor helicopter of identical weight, according to identical disk loading, its rotor radius is single
The 70% of heligyro.
Screw propeller technology：When propeller rotates, blade is constantly pushed large quantity of air (propulsive medium) backward,
A power forward, i.e. propulsive force are produced on blade.Generally, propeller also has pace in addition to rotation.One is intercepted such as
From the point of view of segment blade, just as a bit of wing, its relative air speed is synthesized by pace and rotary speed.Gas on blade
Power constitutes pulling force in the component of direction of advance.Component in the surfaces of revolution forms the torque for preventing propeller rotation, by starting
The torque of machine is balancing.
Big payload helicopter applies to ducted fan technology, and ship and aircraft apply to screw propeller technology.Closely
Nian Lai, duct aircraft have become an international study hotspot.Such duct aircraft can hover and be vertically moved up or down,
And can using duct lean forward generation forward direction pulling force realize before helicopter mode low speed fly, but nose-up pitching moment and resistance are with front
Rapidly the increase of degree and increase rapidly, therefore they be only applicable to hover and low-speed operations occasion.At present, disclose a kind of common
Axle adopts hollow annular configuration and coats anti-direction dual-rotor blade to turning DCB Specimen culvert type vertically taking off and landing flyer, duct casing
Extra leading edge suction is produced, while improving aircraft lift, craft power demand is reduced.It is coaxial to turn DCB Specimen from
Body counteracts spinning moment, is conducive to the stability contorting of attitude of flight vehicle.Every grade of rotor blade is reduced using anti-direction dual-rotor
Aerodynamic loading, advantageously reduces aerodynamic loss, while anti-direction dual-rotor blade reduces eddy flow loss, substantially increases pneumatic efficiency,
Increase cruising time.But above-mentioned aircraft adjustment posture and can not be born away in horizontal plane in the air, and without aiding in
Function.
