Abstract

The invention relates to the people and how to do flapping flight as bird with the strength of self.Trample the handle plate by pin and drive the moving aerofoil of helical wheel Fan by gear wheel, the joystick anglec of rotation of this flapping wing aircraft can be swung empennage and yaw rudder; The front and back push-and-pull can be adjusted the leaning angle of flapping wing; In order to increase the draught head of going up bottom wing, the flapping wing face is made up of the net hair.(net is that air intake, hair are to keep out the wind).Under the situation of vertical uplift: add aircraft deadweight and be 20 kilograms and be sitting in the horizontal minimum power that can produce 100 kilograms of object of stepping on the fixing chair less than common people's thigh if the people weighs 65 kilograms.The pneumatic pressure that wants to make both wings must be in the size of aerofoil greater than load, the speed of flapping wing (inferior/minute) go up reasonably and adjust.

Description

Flapping wing aircraft

The invention relates to the people and how to do flapping flight with the strength of self and drive helical wheel by foot pedal, Fan moves aerofoil.The joystick anglec of rotation of this aircraft can be moved back and forth empennage and yaw rudder, and the front and back push-and-pull can be adjusted the leaning angle of flapping wing face.Flapping wing is made up of the net hair; Purpose increases the draught head of going up lower aerofoil.

Step on the swing arm of certain force distance by the leg flesh of prosperity, (lever principle) reaches the moving wing of Fan; Through the reasonable function of net hair, increased the lifting force that rises; Reduce the resistance of flight, thereby obtained bigger last lower aerofoil difference of pressure.Accomplish stagnation pressure 〉=self body weight and aircraft deadweight to air.Thereby break away from the attractive force of the earth, circling in the air freely to the people.In uphill process: just can easier obtain maximal velocity if take certain gradient upwards to fly forward, under the situation of manpower effect aircraft: flying speed is fast more, near the air that per second flows through the wing is just many more, needn't give the very big downward speed of air, just can obtain enough lifting forces, at this moment laborsaving on the contrary.

Constantly the someone wishes to fly up as bird to oneself setting up wing since ancient times.1985.9 knowing not long ago from Chinese Central Television's news hookup, the moon held a man-power aircraft match in Japan.Neither one can use as the vehicle among them, and neither one can resemble small bird and do flapping flight.

Flapping flight has the place similar in appearance to autogyro, but the method difference of effect air, one is by rotation air to be produced pneumatic pressure; Then directly down pounce on the pneumatic pressure of generation for one.

The present invention provides a kind of new vehicle, by the moving aerofoil of legs and feet Fan; Handle aircraft up and down by the hand wing.

The possibility of doing flapping flight has been started in this invention.Compare flapping wing with aircraft and finished the dual role of wing and propeller, flight, landing need not runway, and safety factor is big, noiseless.

Accompanying drawing 1: describe mainly how gearing is made flapping wing.

The number title of Fig. 1 is: on foot-operated 4 helical wheels 5 of 1 wing arm, 2 steel wires 3 on the helical wheel 6 the spiral shell tooth fixedly curved bar 7 cross steelframes 8 movable steel plate 9 empennages 10 driven axles 11 pedals 12 suedes become mildewed

Fixing two following helical wheels 4 at driven axle 10,, overlapping the telescopic spring active ring of foot-operated handle in following helical wheel both sides; Going up helical wheel 5 for two is being fixed by curved bar 6.Curved bar 5 is fixed on the movable steel plate 8 with driven axle 10, and movable steel plate and imput shaft are all being supported by the steel cross bar, and two double helix gears are fixing with two wing arms 1 respectively, and foot-operated crank motion (front and back) wing arm is crank motion (up and down) also.

Accompanying drawing 2 main descriptions reduce resistance, increase lifting force and steering rudder empennage.

The number title of Fig. 2: 13 straight connection rods, 14 direction levers, 15 ropes, 16 fixed pulleys, 17 joysticks, 18 ropes, 19 bearings, 20 seats, 21 fixed pulleys are fixing helical wheel 23 Inlet Networks 24 balanced weights on curved bar 22 wing baskets 5 of spiral shell tooth on the driven axle 6 10..

Air communication is crossed aerofoil mesh 23 and is reduced resistance greatly and avoided unnecessary work done when aerofoil is lifted on rapidly; Under when pouncing on because fine hair 12 is subjected to the air-flow effect, retaining plug mesh has become two airproof aerofoils, thereby has obtained aerodynamic force.Upper surface has suction like this; Lower surface has pressure, has increased the difference of pressure of last lower aerofoil.The fixed pulley 21 that flight control bar 17 front and back push-and-pulls drive stay cords 18 are ordered by A is adjusted the leaning angle of aerofoils, plays the effect that flies to glide.Joystick rotates up and down and drives direction lever simultaneously by C spot wobble empennage 9 and pull yaw rudder by rope 15 around fixed pulley 16.If turn left, left rope tension the right rope loosens the while balanced weight from center line, and aircraft center of gravity is to the left side, and flight is turned left and just realized.To the right in like manner.Balanced weight is as the term suggests there is the effect of adjustment force distance.

Accompanying drawing 3: mainly describe the cross bar driving system, aerofoil leaning angle, empennage, yaw rudder.

The number title of accompanying drawing 3: 13 straight connection rods, 26 steelframes, 18 halliards, 22 flapping wings, 27 sliding trays, 28 moving rods, 17 handgrips, 29 slide shafts, 7 cross bares, 30 semi-round grooves, 3 yaw rudders, 3 foot-operated 32 governing screw.

7. cross bar is to connect the body frame that supports driving system.Supercentral 2 is (from the bottom to top) driven axle and curved bar at cross bar.

Helical wheel from the foot-operated as can be seen following helical tooth cog interlock transmission that 3. drives the limit, the left and right sides on the driven axle of figure because of last helical wheel and wing arm are fixed as one, is ridden crank motion, and aerofoil is crank motion also.The A point is the end points of aerofoil, be connected with rope 18, rope is received on the moving rod 28 by fixed pulley, and moving rod A point forward rises, the curved bar that (being the aerofoil inclination angle) is fixed on helical wheel simultaneously is the center at semi-round groove 30 with the B point, is that radius is made the garden arc and moved with the B point to the distance R of curved bar.Flight just can more than fly to have glided; Rudder face and empennage are a system.They all have the task of finishing change of direction.Joystick and moving rod link together, and are enclosed within on the slide shaft 29.One of moving rod move back and forth empennage by 13 twistings of steel plate bar by straight connection rod, yaw rudder 31 is simultaneously received on the slide shaft 29 along straight connection rod 13 mistake cross bares ten place's change of directions vertically downward by the B point direction lever rope of ining succession.Empennage is around the straight connection rod rotation like this, yaw rudder left and right sides deflection simultaneously, rudder face 31 is subjected to the effect aircraft change of direction of air-flow to add that the space trace that aircraft has been removed at displacement aircraft center takes place the center of gravity of balanced weight 24, because the direction that these synergy just can change of flight.Rudder face can support receipts as required, and the edge of rudder face is that spring wire constitutes.G(steel wire end points), point is to seesaw along straight connection rod.
