Description

Insect wing imitating propeller

The utility model relates to aircraft propeller, specifically, is a kind of insect wing imitating propeller.

Though today, people made supersonic plane, some ability of insect and birds still induces one to envy endlessly.People to the research of flapping-wing aircraft existing four more than ten years history, but do not make a flapping-wing aircraft as yet, because the made stiff wing of people can't be comparable with the wing of birds with practical value.The wing of insect is simpler than birds, but makes wing by insect wing purely, can not reach ideal effect.Because the unusual sporting flying of insect is to utilize self both sides wing vibration, thereby produces one sweptback air-flow, utilizes its antagonistic force to fly forward then.Therefore, can be made into profile according to this principle and be different from insect wing fully and the identical screw propeller of function, but this screw propeller was not still seen.

The purpose of this utility model is to provide a kind of insect wing imitating propeller that utilizes principle of insect flight to make, though it does not have an insect wing shape, has kept the function of insect wing to greatest extent, can reach the ideal effect of insect flying.

The utility model is done in such a way that this screw propeller mainly revolves seat, blade bar garden annulate shaft, blade bar garden annulate shaft seat, outer sleeve, driving device and blade by fixing spherical inclined shaft, bearing pin, bearing pin and forms.The fixing spherical inclined shaft heart becomes 37 °-40 ° with axostylus axostyle, promptly the ball tangent plane of ball journal becomes 53 °-50 ° with the ball journal bar, and inclined shaft is equipped with bearing pin in the heart and revolves seat, and bearing pin revolves seat and can rotate around the inclined shaft heart.On the garden ring of blade bar garden annulate shaft, tighten up two corresponding bearing pins in its radial centripetal, the bearing pin axle center is vertical with blade bar garden annulate shaft, one end of two bearing pins inserts bearing pin respectively and revolves in the seat last two cooresponding pin-and-holes, bearing pin can relatively rotate in bearing pin revolves pin-and-hole on the seat, annulate shaft two outer ends, blade bar garden are the blade bar, be equipped with blade on the bar, 90 ° each other of garden anchor ring on blade and the blade bar garden annulate shaft i.e. two blades at 45, the blade bar axle bed that bearing is housed is sleeved on the annulate shaft of blade bar garden, and make that the blade bar is radially centrifugal to be stretched out outside the axle bed, and be convenient to adorn blade, can make the annulate shaft rotation of blade bar garden again.The overcoat axle mounting and is connected as a single entity with blade bar axle bed on the major axis of fixing spherical inclined shaft, can rotate around the major axis of fixing spherical inclined shaft.Outer sleeve one termination power drive.The major axis of fixing spherical inclined shaft stretches out outer sleeve, and an end of axle has tool face azimuth and bearing mark, and two ends tighten up the position.

The utility model in use, by the orientation major axis two ends of the fixing spherical inclined shaft on the imitative insect worm wing screw propeller are fixed on the support of aircraft both sides, or an end of major axis is fixed on the support, the major axis of the fixing spherical inclined shaft of the other end stretches on the bearing power take-off shaft axle center in, and the direct and takeoff output of the driving device on the outer sleeve tightens up.Power rotates outer sleeve by the driving device of outer sleeve one end.Outer sleeve rotates blade bar garden annulate shaft together, and the bearing pin on the annulate shaft of blade bar garden makes bearing pin revolve seat and rotates around the fixing spherical inclined shaft inclined shaft heart.Be installed on the fixing spherical inclined shaft axle center because bearing pin revolves seat, bearing pin revolves the garden face of seat and the major axis of fixing spherical inclined shaft has 53 °-50 ° of angles.Bearing pin makes bearing pin revolve seat and turns to blade under when clapping the position, simultaneously bearing pin also relatively bearing pin revolve a turn, blade bar garden annulate shaft and rotate around a major axis of fixing spherical inclined shaft.Instantly photographed certain position, bearing pin makes the result that bearing pin revolves the seat rotation that blade bar garden annulate shaft is rotated around the major axis of fixing spherical inclined shaft, makes the annulate shaft rotation of blade bar garden again, i.e. blade deflection certain angle.Therefore the utility model can be in rotation process, produce lift and pulling force, change rotatablely moving of blade the mode of fluttering of insect into, can reach the effect of insect flying, be applied to aircraft, can make aircraft than existing aircraft have more alerting ability, more energy-conservation, more help popularizing.

Describe structure of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the positive diagrammatic sketch of the utility model

Fig. 2 is the utility model A-A section drawing

Fig. 3 is the utility model blade bar garden annulate shaft seat scheme drawing.

As Fig. 1, Fig. 2, shown in Figure 3, this screw propeller comprise fixing spherical inclined shaft (1), (2) and with the fixing vertically arranged blade bar of spherical inclined shaft garden annulate shaft (13), blade bar (11) and blade (10), the fixing spherical inclined shaft inclined shaft heart (4) becomes 38 ° with fixing spherical inclined shaft major axis (axostylus axostyle) (1), (2), the inclined shaft heart (4) is set with bearing pin and revolves seat (8), bearing pin revolves between seat (8) and fixing spherical inclined shaft inclined-plane thrust baring (14), and bearing pin revolves seat (8) and can rotate around the inclined shaft heart (4).Two pin-and-holes (14) are arranged on radially vertical with blade bar annulus, and bearing pin (7) is fixed tightly in the pin-and-hole (14), and it is entad held and stretches into bearing pin and revolve in two respective pin hole of seat on (8).Bearing pin (7) can relatively rotate in bearing pin revolves the pin-and-hole of seat on (8).Outer sleeve (5), (6) are sleeved on the bearing of fixing spherical inclined shaft axostylus axostyle (1), (2).The blade bar garden annulate shaft seat (12) that bearing is housed is sleeved on the blade bar (11), and blade bar (11) stretches out outside the axle bed (12), so that blade (10) is installed, can make blade bar garden annulate shaft (13), blade bar (11) rotation again.Blade bar garden annulate shaft seat (12) is connected as a single entity with outer sleeve (5), (6), and whole outer sleeve (5), (6) can be rotated around fixing spherical inclined shaft bar (1), (2) with blade bar garden annulate shaft seat (12).Outer sleeve (6) end is provided with wheel word (9).

This screw propeller also can be made of 4 blades, during design, need are fixedly increasing a spherical inclined shaft structure as shown in Figure 1 on ball journal axostylus axostyle (1) or (2), on this spherical inclined shaft structure, one blade bar garden annulate shaft is installed with quadrat method, back one blade bar garden annulate shaft is vertical mutually with last blade bar garden annulate shaft, promptly stretch out 90 ° each other on the four blade bars of blade bar garden annulate shaft seat, the anchor ring of blade face and blade bar garden annulate shaft is 45 ° on the blade bar, 90 ° each other in two blade faces.

The utility model is used for aircraft must adopt twin screw.

Imitative insect screw propeller rotates under the effect of power, when blade is in the following bat process, the blade face turns forward slightly, produce one downward-sloping air-flow similar to insect flying, because the pressure difference of blade upper and lower surface and be tilted to the antagonistic force of downstream to blade, on blade, obtain very big lift and certain thrust, and another blade is in that blade leans forward slightly when lifting process, produces certain thrust equally.Photographed certain position under blade, two blades begin angle of conversion in finishing the angular transformation process, and blade is transformed to backward by being tilted to down gradually the application force of air, thereby make aircraft produce forward propulsion.
