Abstract
The flight machinery includes a structure in which a main body and a lightweight wing having an unvalued weight compared with the main body are connected by use of a power joint on a line joining the center of a lift force and the center of gravity of the wing in the manner that the main body is positioned under the wing. Accordingly, it is possible to exhibit a function of the flight machinery by adjusting the power joint connecting the upper part and the lower part or the wing to the main body even if the wing and the main body have different characteristics. Additionally, it is possible to stabilize a posture by positioning the total center of gravity at the main body at the lower part. At the same time, it is possible to stabilize the posture just by controlling the position of the servomotor of the power joint.
