ORNITHOPTER

摘要

An ornithopter includes a main wing mounted on a fuselage, and a control system configured to control a flapping motion of the main wing. The main wing includes an inner spar, an outer spar, and a wrist portion disposed between the inner spar and the outer spar and which varies a bending angle, which is a relative angle between the inner spar and the outer spar, within a predetermined angle range. The control system includes an actuator which performs a raising motion and a lowering motion of the inner spar by moving the inner spar in an upward direction and in a downward direction, an angle sensor which measures the bending angle, and a control unit which controls the actuator to move the inner spar in response to the measured bending angle.

1. An ornithopter comprising:
a main wing mounted on a fuselage; and a control system configured to control a flapping motion of the main wing, wherein the main wing comprises: an inner spar extending outwardly from the fuselage; an outer spar extending outwardly from the inner spar; and a wrist portion disposed between the inner spar and the outer spar, and configured to vary a bending angle within a predetermined angle range, the bending angle being a relative angle between the inner spar and the outer spar, wherein the control system comprises: an actuator configured to perform a raising motion of the inner spar by moving the inner spar in an upward direction and to perform a lowering motion of the inner spar by moving the inner spar in a downward direction; an angle sensor mounted in the wrist portion, and configured to measure the bending angle; and a control unit configured to control the actuator to move the inner spar in response to the measured bending angle of the angle sensor.
