SINGLE ROTOR MODEL HELICOPTER WITH IMPROVED STABILITY BEHAVIOR

摘要

A single rotor model helicopter is provided, comprising a spindle, a rotor clamp disposed on the spindle, a pair of rotor blades disposed on the rotor clamp, and a pair of hybrid control rocker arms. The helicopter further includes an operating system and a balancing system. The pair of hybrid control rocker arms are disposed on both sides of the rotor clamp respectively and rotatably connected to a pitch control rocker arm through each axial hole located on a center of each hybrid control rocker arm, so as to control attack angles of the rotor blades. Each hybrid control rocker arm has two control points. A first pair of control points diagonally opposite each other in the pair of hybrid control rocker arms are controlled by a cyclic torque transmitted from the operating system, and a second pair of control points diagonally opposite each other are controlled by the balancing system. Furthermore, the second pair of control points controlled by the balancing system and the first pair of control points controlled by a swash plate can move relative to each other as mutual fulcrums. The single rotor model helicopter of the present application can separately adjust operating sensitivity and stability, thereby finding an optimum combination of dynamic stability and maneuverability of the model helicopter.
