Abstract
On teeterboard flap of main rotor rotating around free space point of a 30Kg class unmanned autonomous helicopter (UAH), aerodynamics kinematics model is set up in terms of D' Alembert principle. On conditions of the helicopter physical parameter value, simulation validates the model in reason, and points out：①Teeterboard Flap on main rotor is self-stable system; ②unmanned autonomous helicopter structure plays a leading role on transient process of main rotor teeterboard flap, and relative air current acting on the blade plays a leading role on its steady process.
