Stratospheric regional resident device and method for overpressure balloon

Abstract

The present disclosure provides a stratospheric regional resident device for an overpressure balloon, including a main overpressure balloon and at least two auxiliary balloons, wherein the main overpressure balloon is a buoyant body with load bearing capacity and has the ability to adjust its height to enter different wind layers; and the at least two auxiliary balloons, connected to the main overpressure balloon by a mooring cable, and float respectively above and below the main overpressure balloon through buoyancy distribution. By using the regional resident device of overpressure balloon,the regional residence flight can be completed by using a single main overpressure balloon. By using the combination of a single main overpressure balloon and multiple auxiliary balloons, the accuracyrequirement on wind field prediction is greatly reduced.

Description

technical field [0001] The present disclosure relates to the field of aerostats, in particular to a device and method for staying in the stratosphere region of an overpressure balloon. Background technique [0002] In recent years, driven by the needs of regional atmospheric environment monitoring, disaster prevention and mitigation, high-resolution real-time monitoring, and regional communications, high-altitude airborne aircraft represented by stratospheric airships and superpressure balloons have attracted widespread attention from all countries. Major countries in the world, including China, have successively launched related research programs and started more in-depth research and development work. [0003] There is an area at the bottom of the stratosphere at the junction of easterly and westerly winds, and the wind speed is relatively small. This feature is especially obvious in summer and is called the "quasi-zero wind layer". The use of aiming at the wind-zero lay...

AI Technical Summary

Problems solved by technology

[0006] When a single overpressure balloon is used for long-term airborne tests, it is often impossible to accurately know the change of the wind field above and below its airborne height

If multiple individual superpressure balloons are used for regional networking, the position differences of different superpressure balloons often mean the difference in local wind field, and the reference information that can be given for a superpressure balloon that needs to be adjusted individually is limited.

At the same time, the regional networking of multiple overpressure balloons will undoubtedly increase the complexity of the system and bring inconvenience to use
