Abstract

According to the coaxial rotor's position relative to the center of gravity, three modes, the center of gravity below, between and upon the coaxial rotor, are defined and the computational models are developed. Based on the model, the stability of the helicopter is analyzed, the influence of the coaxial rotor's position relative to the gravity center on the stability of the helicopter is studied, the way to improve the stability of a helicopter with the gravity upon the rotor is also studied. The results show that when the gravity is upon the rotor, the longitudinal movement and the lateral movement are divergent. The increase of the rotor torque can improve the stability of the helicopter.
