A flight machinery with high stability in the air having a pendulum structure and an active posture control principle which can be designed for universal purposes at a low cost is provided. 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. The flight machinery is inexpensive because the structure of the flight machinery is simple, and can be used conveniently and economically in industry because a design/development cost is low.
A flight machinery comprising a main wing and a fuselage as a main body which are connected to each other by a power joint and a telescopic shaft to configure a suspension at a connection portion thereof, wherein an external shock during flight is absorbed by the suspension.
A flight machinery comprising a lightweight wing having 50% or less weight than that of a main body and a fuselage as the main body which are connected to each other by a power joint and a telescopic shaft to configure a suspension at a connection portion thereof, wherein an external shock during flight is absorbed by the suspension.
A flight machinery comprising a lightweight wing having 50% or less weight than that of a main body and a fuselage as the main body which are connected to each other through a power joint and a telescopic shaft on a line joining a center of gravity of the lightweight wing and a center of a lift force to configure a suspension at a connection thereof, wherein an external shock during flight is absorbed by the suspension.
A flight machinery comprising a lightweight wing having 50% or less weight than that of a main body and a fuselage as the main body which are connected to each other by a power driven three-degree-of-freedom joint and a telescopic shaft on a line joining a center of gravity of the lightweight wing and a center of a lift force to configure a suspension at a connection thereof, wherein an external shock during flight is absorbed by the suspension.
