Abstract: When lighter-than-air gas compressed and filled in a pressure-resistant container is injected into an envelope, buoyancy created in the envelope causes an aircraft to ascend. When the aircraft finishes its flight role, a lid of an opening/closing mechanism is opened to exhaust from a port lighter-than-air gas from the envelope. When the buoyancy of the envelope is insufficient to counter the weight of the aircraft, the aircraft begins to descend. The lid of the opening/closing mechanism is closed on the port, and exhaust of lighter-than-air gas from the envelope stops. After the aircraft reaches a surface of land or water, an operator connects a duct to a gas suction device. The gas suction device collects the lighter-than-air gas remaining in the air sac into a container. The lighter-than-air gas collected into the container is transported to a gas collection facility, compressed by a compressor, and filled into a pressure-resistant container.

Abstract: A container for a flight craft such as a gas balloon is provided. Part of the walls of the container is constituted of three separated plates. The first plate has one or more holes that causes gas to flow in and out of two spaces so that the pressure difference between a first space and a second space separated by the first plate is resolved but does not cause gas convection between those two spaces. As the flight craft ascends, a relationship T1<T2<T3<T4 occurs among the temperatures inside the first to a fourth space. The temperature gradient between the inside and outside of the container becomes less pronounced. Condensation is unlikely to form on any of the three plates. The first plate with the holes buffers the force that the second plate is subjected to due to a pressure difference between the inside and outside of the container.

Abstract: The present invention ensures that when condensation forms in a container for a flying object, water from the condensation does not adversely affect an object in the container. Container 12 is a cabin of a gas balloon and comprises Main Body 121, which is an airtight container for accommodating Crew Member H1 and is filled with Air 122, Condensation Promoting Member 123 is made of a material that has a high thermal conductivity, such as aluminum, and is partly exposed to the inside of Main Body 121 and partly exposed to the outside of Main Body 121. Water Collecting Vessel 124 is positioned below the portion of Condensation Promoting Member 123 exposed to the inside of Main Body 121 and collects water from condensation formed on Condensation Promoting Member 123. Conduit 125 directs water collected by Water Collecting Vessel 124 to Water Collection Container 126.

Abstract: Container 12 is a cabin of a gas balloon, Container 12 has Main Body 121, which is an airtight container for accommodating Crew Member H1 and is filled with Air 122, Heat Transfer Member 125 made of a material that has a high thermal conductivity such as aluminum and that covers the inside of Main Body 121 and is partially in contact with Heat Absorber Holder 123, Heat Absorber Holder 123 that is a container made of a material that has a high thermal conductivity, such as aluminum, and is located outside of Main Body 121, and Heat Absorber 124 contained in Heat Absorber Holder 123. Heat generated by Crew Member H1 is transferred via Air 122 to Heat Transfer Member 125 and then to Heat Absorber Holder 123. Heat Absorber 124 absorbs heat from Heat Absorber Holder 123 as heat of vaporization and changes from a liquid to a gas.

Abstract: The invention provides an inexpensive means of transporting people and objects to altitudes of 10,000 meters or more. Flying System 1 has Balloon 11, Suspension Lines 12 hanging downwards from Balloon 11, and Cabin 13 attached to the lower ends of Suspension Lines 12. The main body of Cabin 13 consists of laminated walls that include a fiber-reinforced plastic layer that keeps Cabin 13 watertight and airtight and also serves to maintain the shape of Cabin 13, an ultra-violet-rays blocking layer that reduces the amount of ultra-violet-rays transmitted into Cabin 13, an insulation layer that reduces the amount of heat conducted from the inside to the outside of Cabin 13, and an adhesive layer that enters and seals a crack or hole in the fiber-reinforced plastic layer when the crack or hole appears. The side walls of the main body of Cabin 13 have two hatches located opposite each other.

Abstract: The present invention reduces a probability of condensation forming in a container for a flying object. Container 12 is a cabin of a gas balloon. Container 12 comprises Main Body 121 that is an airtight container filled with air and accommodating Crew Member H1, and Partition 122 that divides the space in Main Body 121 into Space S1 and Space S2. Partition 122 has one or more narrow Holes H. When the altitude of the flying object increases and Container 12 cools from the outside, air in Space S1 cools more slowly than the air in Space S2. A pressure difference between Space S1 and Space S2 is rapidly equalized by air flow through Holes H, but it takes a long time to equalize a temperature difference between Space S1 and Space S2. Therefore, a temperature in Space S1 becomes higher than a temperature in Space S2, and a temperature in Space S2 becomes higher than a temperature in the space outside Main Body 121.

Abstract: The present invention provides a means by which heat generated in an airtight container for a flying object flying at high altitude can be exhausted to the outside. Container 12 is a cabin of a gas balloon and comprises Main Body 121, which is an airtight container for accommodating Crew Member H1 and is filled with Air 122, Heat Transfer Member 125 made of a material that has a high thermal conductivity such as aluminum and that covers the inside of Main Body 121 and is partially in contact with Heat Absorber Holder 123, Heat Absorber Holder 123 that is a container made of a material that has a high thermal conductivity, such as aluminum, and is located outside of Main Body 121, and Heat Absorber 124 contained in Heat Absorber Holder 123. Heat generated by Crew Member H1 is transferred via Air 122 to Heat Transfer Member 125 and then to Heat Absorber Holder 123. Heat Absorber 124 absorbs heat from Heat Absorber Holder 123 as heat of vaporization and changes from a liquid to a gas.

Abstract: The present invention provides a means of easily attaching and detaching a member that reinforces an envelope of a balloon to and from the envelope. Balloon 1 according to an embodiment of the present invention comprises Inner Member 121 and Outer Member 123. Each of Inner Member 121 and Outer Member 123 is a disk-shaped member made of a plastic, a light metal, or other lightweight material. Inner Member 121 and Outer Member 123 are attached to Envelope 11 by tightening Bolts 125 and Nuts 126, with Envelope 11 therebetween. A donut-shaped Rubber Seal 122 is located on the surface of Inner Member 121 in contact with Envelope 11, and a donut-shaped Rubber Seal 124 is located on the surface of Outer Member 123 in contact with Envelope 11. Rubber Seal 122 and Rubber Seal 124 are pressed tightly against Envelope 11 as Bolts 125 and Nuts 126 are tightened, and Holes H2 provided in Envelope 11 to accommodate Bolts 125 are sealed.
