Rotary wing blade type flapping wing air vehicle

Abstract

The invention discloses a rotary wing blade type flapping wing air vehicle belonging to the technical field of aviation. The rotary wing blade type flapping wing air vehicle mainly comprises an air vehicle body, a tail rotor, a left rotary flapping wing device, a right rotary flapping wing device and an undercarriage, wherein the air vehicle body is internally matched with an operation control system, a self-navigated autonomous flight instrument and a remote control system; the left rotary flapping wing device and the right rotary flapping wing device are same in structure, parameter and working principle and are symmetrically arranged at a left support and a right support extending at the left and right sides of the air vehicle body; the tail rotor is driven by a small motor; the right rotary flapping wing device comprises an engine, a main shaft, a rotary arm, a central fixed gear, a first near-center gear, a first remote-center gear, a first wing blade, a second near-center gear, a second remote-center gear and a second wing blade; the meshing transmission ratio of all gears is 1:1; and the first wing blade and the second wing blade alternately upwards and upwards rush to generate a forward thrust force and an upward thrust force. The rotary wing blade type flapping wing air vehicle is used for meeting the requirements of aerial photography, agriculture, forestry and animal husbandry works and military affairs.

Description

technical field [0001] A flapping-wing aircraft with rotating blades belongs to the technical field of aviation, and in particular relates to a flapping-wing aircraft. Background technique [0002] The wings of a traditional flapping-wing aircraft flutter according to a circular arc trajectory. When the wings flap up and down, a part of the aerodynamic component is generated in the horizontal horizontal direction. This horizontal component has no positive effect on the forward movement and lift-off of the flapping-wing aircraft. The effect is a loss of power. Wings flutter up and down, there is a turning process, and the movement continuity is poor; the Chinese patent No. ZL200910073435.8 discloses a flapping wing lift generating device with a relatively complicated structure that relies on the flapping wing lifting mechanism to reset the flapping wing sheet, although the efficiency is relatively high. The traditional flapping wing is higher, but during the flapping process...

Problems solved by technology

Wings flutter up and down, there is a turning process, and the movement continuity is poor; the Chinese patent No. ZL200910073435.8 discloses a flapping wing lift generating device with a relatively complicated structure that relies on the flapping wing lifting mechanism to reset the flapping wing sheet, although the efficiency is relatively high. The traditional flapping wing is higher, but during the flapping process, only the middle position of the fin is in the horizontal position. At other times, there is an angle between the fin and the horizontal plane. The further away from the middle position, the larger the angle is, and the lift generated is the fin The vertical component of the force, the horizontal component becomes a loss, and the efficiency of generating lift is also limited
