The invention discloses a novel micro unmanned aerial vehicle (UAV) using a biomimetic wing, belonging to the field of micro unmanned aerial vehicle (UAV). The invention comprises a bionic leading edge, a main wing, a power system, a motor rack and a pneumatic rudder surface; The leading edge of the main wing is a fixed rectangular wing, and the leading edge of the main wing is a sinusoidal leading edge whose crest number is n, n >= 3, which is processed on the straight leading edge of the fixed rectangular wing, and the leading edge of the main wing is a sinusoidal leading edge whose crest number is n. The novel micro unmanned aerial vehicle (UAV) provided by the invention adopts a novel wing plane with a biomimetic sinusoidal leading edge to improve the self-induced rolling oscillation phenomenon of the micro unmanned aerial vehicle (UAV) at a high angle of attack, improve the flight stability of the aircraft, and has simple structure and convenient design and processing.
