Abstract

The utility model relates to a bird type miniature aerocraft, comprising an aerocraft body, an engine arranged in aerocraft body, a transmission mechanism and an operating mechanism. The aerocraft body forms a bird shape, composed of a bird head, a bird body, a bird tail, bird wings, and bird feet. The transmission mechanism is composed of a transmission-gear, a speed variator, a driving belt, a crankshaft arranged on upper part of the bird body. The bird wings are connected with the crankshaft by a connecting fitting, and the bird wings can flick to produce the power of flight with the rotation of the crankshaft. The aerocraft has the advantages of small volume and convenient operation, which can rise and land freely like the bird and is not required of a special airport. Compared with the existing aerocraft, the utility model has simple structure and low cost, and thus, the aerocraft can bring convenience to the life of people.

Description

Bird-like miniature aerocraft

The utility model belongs to aircraft, particularly relates to a kind of minute vehicle of short range low-latitude flying.

Existing aircraft cost height is mainly used in the high-altitude long-distance flight, thereby use face is restricted, and can not satisfy the needs of the short range low-latitude flying of the extensive needs of people.

The purpose of this utility model is to provide a kind of bird type aircraft that declines, and it can carry people and freely circle in the air as the bird.

The purpose of this utility model is achieved in that the flight theory according to birds, and Flight Vehicle Design is become bird formula structure.This kind aircraft comprises driving engine, transmission device and the operating mechanism of installing in body, the body.Body be shaped as the bird shape, form by bird head, bird body, bird tail, pinion and bird pin, pinion is with the rack-mount formation of some arc movable sheets; Transmission device is made up of the power wheel of installing on the engine shaft, transmission system and driving band and the bent axle that is installed in the bird body; Pinion links to each other with bent axle by attaching parts, and flashes the generation flying power with the rotation of bent axle.

The utility model provides a kind of new transport facility for people, and volume is little, easy to use, can be as the bird free lifting, do not need special-purpose airport, and simple with existing aircraft structure compared, therefore cost is low, uses face width, bring great convenience can for people's life.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the decline structural representation of type aircraft of a kind of bird of proposing according to the utility model.

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

As shown in Figure 1, the aircraft in the present embodiment comprises body, driving engine (1), transmission device and operating mechanism.Body be shaped as the bird shape, form by bird head (13), bird body (18), bird tail (14), pinion (10) and bird pin (25).Bird head (13) is installed on the A-pillar (20) of bird body, bird tail (14) is installed in that the rear column (21) of bird body is gone up, bird head (13) is connected by break-in pipe link (15) with bird tail (14), when the bird head was changed direction, the bird tail is translation-angle correspondingly also.Pinion (10) is installed in support (12) with some camber movable sheets (11) and goes up formation, and when pinion flashed up and down, camber movable sheet (11) can open or be closed.Driving engine (1) is installed in the casing of bird body (18) formation, is used to produce power.Transmission device is made up of the power wheel of installing on the engine shaft (2), the transmission system that links to each other with power wheel and driving band (3) and the bent axle (4) that is installed in bird body (18) top, bent axle is to drive the parts that pinion flashes up and down, and pinion (10) links to each other with bent axle with movable button (5) on being enclosed within crankshaft neck by lower support bar (8).Operating mechanism is made up of handle (17), control lever (16), break-in pipe link (15), movable connecting rod (24), movable button (6) (7), upper support bar (9).Handle (17) links to each other with break-in pipe link (15), can realize direction of operating; The axle that movable button (6) is enclosed within bent axle (4) turns, movable button (7) links to each other with movable button (6) and links to each other with the upper support bar (9) that is supported on the pinion top, control lever (16) links to each other with upper support bar (9) by movable connecting rod (24), so the angle of control lever (16) may command pinion.

Flight theory of the present utility model is as follows:

The generation principle of 1 flying power

The power that driving engine (1) produces drives bent axle (4) by power wheel (2), transmission system and driving band (3) and rotates, thereby makes pinion (10) flash the generation flying power.When pinion upwards flashed, all the arc movable sheets on it were subjected to the drag effect of air and open downwards voluntarily, made to stop that the air that pinion upwards flashes passes through from open movable sheet space, thereby reduced the resistance that upwards flashes; When pinion flashed downwards, all arc movable sheets were subjected to the drag effect of air and upwards close up into full closeding state voluntarily on it, and pinion is produced under the effect of air resistance upwards or flying power forward.

2 principles that turn to

Bird head (13) is connected by break-in pipe link (15) with bird tail (14), makes the bird head when changing direction, and the bird tail is translation-angle correspondingly also.When the bird head turned to the left side, a bird tail left side was low right high; When the bird head turned to the right, a bird tail left side was high right low.Therefore, when the bird head turned to the left side, bird tail right flank was met the sky resistance, make aircraft under the resistance of air left-handed turning to; In like manner, aircraft also be under the resistance of air right-hand turning to.Bird trail the bird head about turn to and translation-angle, play the balance air resistance and impact body and balancing steering, to reach the purpose that aircraft turns to arbitrarily.

Method of operation of the present utility model is as follows:

Operating handle (17) and control lever (16) make double-vane become horizontal when taking off, the bird head becomes vertical configuration with the bird tail; Lift-off behind the built on stilts and later circling in the air become the shape that leans forward with double-vane, and bird head and bird tail then turn to according to air objective; Then double-vane is transformed to the hypsokinesis shape when retreating, bird head and bird tail still turn to according to air objective; Landing is during near ground, with double-vane and bird head, state when the bird tail reverts to and takes off.

The flying speed of aircraft is controlled by transmission system.

Claims (1)

1, a kind of bird type aircraft that declines comprises driving engine (1), transmission device and the operating mechanism installed in body, the body, it is characterized in that:

1. body be shaped as the bird shape, form by bird head (13), bird body (18), bird tail (14), pinion (10) and bird pin (25), pinion (10) is installed in support (12) with some arc movable sheets (11) and goes up and form,

2. transmission device is made up of the power wheel of installing on the engine shaft (2), transmission system and driving band (3) and the bent axle (4) that is installed in bird body (18) top,

3. pinion links to each other with bent axle by attaching parts, and flashes the generation flying power with the rotation of bent axle.
