This study focuses on aerodynamics of bionic flap-equipped wings for flapping-wing air vehicles , tackling high-angle-of-attack stall issues. Through 2D numerical simulations, it investigates active flap effects: pre-stall flaps reduce lift, while those at 70% chord length boost lift by ~25% post-stall via vortex regulation. Findings clarify flap-main wing coupling to optimize FWAV performance.
