Abstract

The utility model relates to an aerial vehicle which imitates the flight method of the birds. An U-shaped slot is arranged on the surface of a flapping wing to form a piece of elastic piece, a piece of slice is connected at the lower part of the elastic piece of the flapping wing, a control box is connected on the machine body, a motor is connected in the control box, the motor is connected with a crank, the crank is connected with a sliding bar, a sliding block is connected on the sliding bar, the sliding block is connected with two connecting bars to pull the flapping wing to flap, an horizontal tail servo actuator, a vertical tail servo actuator and a control servo actuator are connected at the back of the machine body, the control servo actuator is connected with the control box through a rotating disk and a shifting lever, the control box is connected with a rotating shaft, the horizontal tail servo actuator is connected with a horizontal tail through the rotating shaft and the shifting lever, and the vertical tail servo actuator is connected with the vertical tail through the rotating shaft and the shifting lever. The utility model has the advantages as follows: firstly, the vertical flapping resistance force of the flapping wing is weak; secondly, under the control of the servo actuator, the flapping wing aerial vehicle is mobile and flexible, the operation is simple, and the oil consumption is low; thirdly, the structure is simple, and the manufacture is convenient.

Description

Flapping wing aircraft

Technical field

The utility model relates to a kind of flapping wing aircraft, particularly a kind of aircraft of copying the birds flying method.

Background technology

Birds circle in the air on high, free and relaxed, people are when the various flapping wing aircraft of research, all to copy the aircraft of birds flying method, existing flapping wing aircraft, flapping wing sheet are one-piece sheet, when fin is pounced on up and down, pounce on down generation to raising force and on pounce on the downward lift that is produced and differ less, therefore make the flapping wing aircraft weak effect that comes.

Summary of the invention

The purpose of this utility model provides a kind of flapping wing aircraft, when its fin is fluttered up and down, pounces on the downward lift of pouncing on generation on raising force is far longer than of generation down, thereby improves the flight effect of flapping wing aircraft.The aircraft maneuverability, processing ease.

The utility model is achieved like this, it comprises body, flapping wing, control box, motor, steering wheel, driving lever, horizontal tail, vertical fin, control box connects flapping wing by axostylus axostyle, have U type groove on the flapping wing surface, form a shell fragment in the middle of the U type groove, below the shell fragment of flapping wing, connect a thin slice, when pouncing under the flapping wing, thin slice is sealed U type groove, and the lift that makes progress is big, when pouncing on the flapping wing, under the effect of air, shell fragment opens, and U type groove crack increases, top airfoil and lower aerofoil pressure reduction are little, and downward lift is little; Body connects control box by rotating shaft, and motor is fixed on the control box bottom, the motor connecting crank, and the crank connecting link connecting rod, connecting rod connects the slide block on the slide bar, and slide block connects other two connecting rods pulling flapping wing and flutters around axostylus axostyle; The horizontal tail steering wheel, vertical fin steering wheel and control steering wheel are fixed on After-Body, and the rotating disk on the control steering wheel connects control box by driving lever, and the rotating disk on the horizontal tail steering wheel connects horizontal tail by driving lever, and the rotating disk on the vertical fin steering wheel connects vertical fin by driving lever.

The utility model has the advantages that: 1, the flapping wing efficient height of fluttering up and down; 2, under the control of three steering wheels, the flapping wing aircraft maneuverability is handled easily, and oil consumption is little; 3, simple in structure, easy to make.
