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.
