Abstract：All the translational motion components of helicopter and the position parameters of tail drive shaft do not affect the critical speed of tail drive shaft, and only the rotational motion components of helicopter affect the critical speed of tail drive shaft. The influence of the rotational motion components of helicopter on the critical speed of tail drive shaft was analyzed. The results reveal that the yaw angular velocity with the critical speed of horizontal drive shaft is parabola relation, the yaw angular velocity with the critical speed of oblique drive shaft is linear relation and the relation curve is symmetrical. The symmetry axis will offset to the left as the increase of the inclination angle of oblique tail drive shaft. The influence of the pitching angular velocity on the critical speed of tail drive shaft is the same as yaw angular velocity. The relationship between the rolling angular velocity and the critical speed of horizontal drive shaft and oblique drive shaft are all linear relation, and the symmetry axis will offset to the right as the increase of the inclination angle of oblique tail drive shaft. The angular velocity of symmetry axis of the second-order critical speed of drive shaft is about 16 times of the first-order critical speed.
