Abstract
The utility model discloses a rotatable flapping wing thrust generation device with a spring and belongs to the technical field of aircrafts. The rotatable flapping wing thrust generation device consists of a spindle, a rotation arm, a flapping ring, a wing shaft, a spring and a hook, wherein the spindle, the rotation arm and the wing shaft are combined to form a crank; one end of the spring is fixedly connected to the flapping wing, and the other end of the spring is connected to a machine body through the hook. The flapping wing is capable of rotating circumferentially under the driving of an engine, flapping the air to generate thrust; the rotatable flapping wing thrust generation device is high in efficiency, low in requirements on fatigue strength of materials, simple in structure and capable of conveniently adjusting the direction of the thrust, so that the rotatable flapping wing thrust generation device can be used as a thruster for the aircraft.
Description
Technical field
With a rotary flapping wing thrust generating apparatus for spring, belong to vehicle technology field, relate in particular to a kind of aircraft thrust generating apparatus.
Background technology
Traditional flapping wing aircraft is to drive flapping wing by crankshaft-connecting rod mechanism, and flapping wing is fluttered up and down and produced lift, and its efficiency is lower, and direction is not adjusted the direction of lift, and the strength at repeated alternation of flapping wing material is had relatively high expectations.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect of traditional flapping wing aircraft, invent the rotatable similar flapping wing thrust generating apparatus that rolls the wing that a kind of efficiency is higher.
With a rotary flapping wing thrust generating apparatus for spring, formed by main shaft, pivoted arm, flapping wing, wing axle, spring and hook; One end of main shaft is connected with flapping wing aircraft fuselage by bearing, one end of pivoted arm is vertical with the other end of main shaft to be connected, vertical being connected in one end of the other end of pivoted arm and wing axle, wing axle, pivoted arm and main shaft form crank in same plane, and the other end of wing axle is connected in flapping wing root the leading edge place near flapping wing by bearing and flapping wing; The end face of the close pivoted arm of flapping wing is that the root end face of flapping wing is vertical with the leading edge of flapping wing, and one end of spring and flapping wing are fixed on the intersection point place of this end face string of a musical instrument and trailing edge, and the other end of spring is connected with fuselage by hook; Hook is installed near the rotation round of wing axle, but the distance of linking up with between main shaft is greater than arm length, flapping wing maximum chord length and spring original length three sum, to guarantee that flapping wing rotates smoothly; Flapping wing is rigidity.
The principle of work of this kind of rotary flapping wing thrust generating apparatus with spring is: the power of driving engine passes to main shaft after slowing down, main shaft rotates and drives pivoted arm rotation, pivoted arm drives the rotation of wing axle, flapping wing rotation under the traction of wing axle, due to the control of spring, when flapping wing rotation, its angle of attack revolves at a cycle of operations the interior meeting of turning around regular variation occurs, and meets flapping wing, is conducive to produce thrust.Because hook is near the rotation round of wing axle, in one-period, the effect of flutterring generation under flapping wing much larger than on flutter, the efficiency that produces lift is higher.Change the size that the rotating speed of driving engine can change thrust, the faster thrust of rotating speed is larger, in the time that rotating speed is constant, is hooked into distance between main shaft and can be changed the size of thrust by change; The direction of thrust is linked up with the relative azimuth of main shaft and highly realized by change.Because flapping wing is made circular-rotation, less demanding to the strength at repeated alternation of material.This apparatus structure is simple, and efficiency is higher.
Brief description of the drawings
Fig. 1 is that the master of a kind of rotary flapping wing thrust generating apparatus with spring of the present invention looks schematic diagram; Fig. 2 is the birds-eye view of Fig. 1.
In figure, 1-main shaft, 2-pivoted arm, 3-flapping wing, 4-wing axle, 5-spring, 6-hook; In Fig. 1, the large broken circle with arrow represents rotational trajectory and the rotation direction of wing axle 4, and the hollow arrow at pivoted arm 2 places represents the rotation direction of pivoted arm, near the switch direction of the four-headed arrow arc representation spring 5 hook 6 left sides.
Detailed description of the invention
Now by reference to the accompanying drawings 1 and accompanying drawing 2 for example the present invention is illustrated.
With a rotary flapping wing thrust generating apparatus for spring, formed by main shaft 1, pivoted arm 2, flapping wing 3, wing axle 4, spring 5 and hook 6; One end of main shaft 1 is connected with flapping wing aircraft fuselage by bearing, vertical being connected of the other end of one end of pivoted arm 2 and main shaft 1, vertical being connected in one end of the other end of pivoted arm 2 and wing axle 4, wing axle 4, pivoted arm 2 and main shaft 1 form crank in same plane, and the other end of wing axle 4 is connected in flapping wing 3 roots the leading edge place near flapping wing 3 by bearing and flapping wing 3; The end face of the close pivoted arm 2 of flapping wing 3 is that root end face is vertical with leading edge, and one end of spring 5 and flapping wing 3 are fixed on the intersection point place of this end face string of a musical instrument and trailing edge, and the other end of spring 5 is connected with fuselage by hook 6; Hook 6 the rotation rounds near wing axle 4 install, but hook 6 and main shaft 1 between distance be greater than pivoted arm 2 length, flapping wing 3 maximum chord length and spring 5 original length three sums, to guarantee that flapping wing 3 rotates smoothly; Flapping wing 3 is rigidity.
The principle of work of this contrive equipment is: the power of driving engine passes to main shaft 1 after slowing down, main shaft 1 rotates and drives pivoted arm 2 to rotate, pivoted arm 2 drives wing axle 4 to rotate, under the traction of wing axle 4, flapping wing 3 rotates, due to the control of spring 5, when flapping wing 3 rotates, its angle of attack revolves at a cycle of operations the interior meeting of turning around regular variation occurs, and meets flapping wing, is conducive to produce thrust.Because hook is near the rotation round of wing axle 4, in one-period, the effect that flapping wing is flutterred generation for 3 times much larger than on flutter, the efficiency that produces lift is higher.Change the size that rotating speed can change thrust, the faster thrust of rotating speed is larger; In the time that rotating speed is constant, link up with 5 by change and also can change the size of thrust to the distance between main shaft 1, hook 5 from main shaft 1 more close to thrust larger; The direction of the thrust that flapping wing 3 produces is linked up with 5 with the relative azimuth of main shaft 1 and highly realized by change, if main shaft 1 front, hook 5 is rear, hook 5 is from moving with high position with main shaft 1, the direction of thrust can be toward moving forward.Because flapping wing 3 is made circular-rotation, less demanding to the strength at repeated alternation of material.This apparatus structure is simple, and efficiency is higher, and the direction of more convenient adjustment thrust.
A kind of rotary flapping wing thrust generating apparatus mounted in pairs with spring of the present invention can be aircraft on small aircraft provides lift and thrust; It is arranged on dirigible thrust can be provided.
