Description
Technical field
With a flat-type flapping wing lift device for servomotor, belong to technical field of aerospace, particularly relate to a kind of flapping wing lift generating device.
Background technology
Instigate to produce lift under traditional Lian Gan Ji Ju flapping wing is top, when flapping wing raises up, resistance is comparatively large, and efficiency is lower, and the lift that can produce is limited, is difficult to realize heavy-duty flight, flapping wing lift generating device flapping wing sheet being resetted by flapping wing lift system that the patent No. a kind of structure disclosed in the Chinese patent of ZL200910073435.8 is more complicated and existing half-rotating mechanism flapping wing device, although the more traditional flapping wing of efficiency is high, but flutter under fin in process, midway location fin is only had to be horizontal, other time fin and horizontal surface all there is an angle, more leave midway location angle larger, the lift produced is the component of the vertical direction of fin application force, the component of horizontal direction has become loss, therefore the limited efficacy of these two kinds existing flapping wing device generation lift.
Summary of the invention
The object of the invention is the above-mentioned deficiency overcoming existing flapping wing device, invent the flat-type flapping wing lift device of the higher band servomotor of the simple efficiency of a kind of structure.
With a flat-type flapping wing lift device for servomotor, comprise main shaft, pivoted arm, fin, center sprocket wheel, chain, wing sprocket wheel, servomotor, servocontrol actuator and frame.Fin is made up of dull and stereotyped and wing axle, and wing shaft rear end and flat board are fixed on dull and stereotyped front center, and dull and stereotyped and wing axle is in same plane.Flat board is rigidity.Main shaft is arranged in frame by bearing level, the stage casing that be fixed on main shaft vertical with main shaft, one end of pivoted arm, and the other end of pivoted arm is by the bearing stage casing that be connected in wing axle vertical with the wing axle of fin.Wing axle and main axis parallel.The follower head of center sprocket wheel is connected in the front end of main shaft by bearing and main shaft.Servomotor is arranged in frame, and the output shaft of servomotor and the front end of center sprocket wheel are connected.What power for servocontrol actuator and servomotor is the lithium cell of convenient charging.Wing sprocket wheel and wing axle are fixed on the front end of wing axle, and wing sprocket wheel is connected by chain with center sprocket wheel, and the transmitting ratio of center sprocket wheel and wing sprocket wheel is 1: 1.Chain movement plane is vertical with main shaft.There is signal with the main power of drive shaft and be connected in servocontrol actuator, guarantees that raise up process servomotor and spindle synchronous of fin rotates, fin is run to the process of highest point from lowest part on the left of main shaft and remains vertical with pivoted arm; And it is motionless to flutter process servomotor stall pinning center sprocket wheel under guaranteeing fin, fin is run to the process of lowest part from highest point on the right side of main shaft and remains horizontality.When assembling the flat-type flapping wing lift device of this band servomotor, fin horizontal arrangement when guaranteeing that pivoted arm is in vertical position directly over main shaft.
The principle of work of the flat-type flapping wing lift device of this band servomotor: under to flutter reference position be that pivoted arm is vertically arranged in directly over main shaft and is namely in 12 o ' clock positions, now fin is horizontal and is positioned at highest point.Under flutter process servomotor and be in stop state.From the rear end of main shaft toward front end, active force inputs from the rear end of main shaft, under the driving of active force, main shaft rotates clockwise, and drives pivoted arm to rotate clockwise, center sprocket wheel is pinned by servomotor and maintains static, because the transmitting ratio of center sprocket wheel and wing sprocket wheel is 1: 1, chain-driving wing sprocket wheel rotates counterclockwise, and keeps fin to be horizontal down and flutters, to be in fin when namely vertical position is in 6 o ' clock position immediately below main shaft to be in extreme lower position when pivoted arm goes to, complete down the process of flutterring.The process of raising up is: from fin is in extreme lower position, main shaft continues to rotate clockwise under the driving of active force, drive pivoted arm to continue clockwise direction upper left side to rotate, under the control of servocontrol actuator drives, servomotor drives center sprocket wheel to rotate with spindle synchronous simultaneously, remains vertical with pivoted arm to guarantee that fin runs to the process of highest point from lowest part on the left of main shaft.When pivoted arm go to be in directly over main shaft vertical position be namely in for 12 o'clock time, fin is in extreme higher position, completes the process of raising up, and this device gets back to the incipient state of time flutterring process.Under the control of servocontrol actuator, servomotor stops operating, and main shaft continues clockwise and rotates under the driving of active force, enters next cycle of operations.Main shaft continuous clockwise under the driving of active force rotarily drives pivoted arm and rotates, and control center's sprocket wheel periodically stall under the driving of the pulse current matched with spindle speed that exports at servocontrol actuator of servomotor, to realize flutterring and raising up continuously motion process, the lift that spindle speed produces sooner is larger.
Flutter process fin under this contrive equipment and be in horizontality all the time, therefore can produce comparatively lift, because application force does not almost have component in the horizontal direction, therefore the efficiency producing lift is very high.The process fin of raising up remains vertical with pivoted arm, and resistance is less.
The flat-type flapping wing lift apparatus structure of band servomotor of the present invention is simple, and efficiency is high, can produce larger lift.This device symmetry of even numbers uses and can manufacture the higher class flapping wing aircraft of efficiency on board the aircraft.This device adopts the active force Direct driver of circular movement, conveniently configures main power, controls also very convenient.Main power can adopt combustion engine or motor.
Can be lightly by the structural weight that the Chain conveyer mode that center sprocket wheel, chain and wing sprocket wheel form is replaced with toothed belt transmission mode apparatus of the present invention, center sprocket wheel, chain are corresponding with wing sprocket wheel is replaced with central synchronous wheel, Timing Belt and wing synchronizing wheel, and central synchronous wheel is 1: 1 with the transmitting ratio of wing synchronizing wheel.
