Abstract: Disclosed is an automatic climbing and gliding method of a high altitude unmanned aerial vehicle (UAV). The disclosed method includes setting a cylindrical virtual flight region so that the high altitude UAV climbs and glides, setting a first target point on an end of a first flight radius which is vertically arranged to form the virtual flight region, setting second to Nth target points at arbitrary second to Nth flight radii sequentially arranged above or below the first flight radius, having the target points have a predetermined plane slope angle, and allowing the UAV to climb along a straight path line sequentially connecting each of the target points.

Abstract: As a component of an aerial vehicle, a power management system having an active power control device is provided. The system includes a solar cell converting solar energy into electric energy; a fuel cell provided in the aerial vehicle and converting fuel energy into electric energy by electrochemical reaction; a battery compensating for a lack of electric power supplied from the solar cell and the fuel cell to the aerial vehicle and storing surplus electric power; and an active power control device connecting with all the solar cell, the fuel cell and the battery and combining and distributing electric power generated in the solar cell, the fuel cell and the battery to loads. The system efficiently distributes the power from the respective power sources through the controllable output of the fuel cell in accordance with power required by the aerial vehicle and the solar cell's performance depending on weather.
