Abstract:
A super-pressured high-altitude airship comprising:a gas bag, which forms an envelope, allows no in-flow or out-flow of a gas from or to, respectively, an outside atmospheric air at a mission altitude, said gas bag being pressure-resistant so as to endure a rise in internal pressure, and said gas bag having a super-pressure structure to maintain a rigidity necessary for said envelope by a pressure difference between said internal pressure and the outside atmospheric pressure; anda solar cell arranged on an upper external surface of said envelope; anda heat blocking means, provided below an installation surface of said solar cell, configured to prevent heat from said solar cell from being transferred to said gas, which is buoyant and which is filled in said envelope, and also configured to prevent said rise in said internal pressure, wherein said heat blocking means includes a ventilation space, located between said gas bag and said installation surface of said solar cell, and a ventilating means configured to forcibly circulate the outside atmospheric air in said ventilation space, wherein said ventilating means includes a suction fan provided on an air inlet on said ventilation space, and wherein said suction fan is driven by an excessive power generated by said solar cell.
