Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0056] The entire system of the sphere system is ultra-miniaturized, close to the limit of the floatability of the tethered aerostat, limited by the density of the material and the buoyant gas, the smaller aerostat is basically unable to carry its own weight. The sphere body is an oblate spherical body of revolution, which is easy to manufacture and is suitable for small capsules. Compared with the true spherical shape, when the flat spherical shape is used for mooring aerostats, the windward surface is smaller, and the wind resistance effect is better and more stable. However, a too flat spherical shape will reduce the body-to-surface ratio of the sphere and increase the surface area of ​​the airbag with the same volume,...

Abstract

The invention discloses a subminiature tethered balloon system and relates to the field of tethered balloons. The system comprises a balloon body system, a winch system, an inflation system, a ground control and receiving system, a mooring rope system, a loading system and a containing and carrying system. A balloon body in the balloon body system is a flat round rotary balloon body, the wind-resistant effect is good, stability is good, winding and unwinding are convenient, and occupied space is small. A power system in the winch system is a winding and unwinding manual rocker or a winding and unwinding motor, and is convenient to carry. The subminiature tethered balloon system is easy and convenient to operate, the number of operators in need is small, quick deployment can be achieved, and the tethered balloon system is flexible. Requirements of sites are low, and the tethered balloon system can be unfolded and released in cities, countryside or remote areas.

Description

technical field [0001] The invention relates to the field of tethered balloons, in particular to a small tethered balloon system. Background technique [0002] The use of aerial platforms to carry loads for observation, communication, aerial photography and other tasks has been widely used for a long time. The aerial platform provides an observation angle and coverage capability that the ground platform does not have, and has better survivability and communication capabilities. The platforms it can carry include tethered balloons, unmanned aerial vehicles, airships, etc. Different platforms have their own advantages and disadvantages, and they should be used in suitable occasions. UAVs have short battery life, small load, and poor safety, and are suitable for short-term aerial photography; airships have good maneuverability and stable flight, and can be used for short-term aerial photography and observation; although tethered balloons are fixed in a certain area and cannot m...
