The invention provides a multi-air-column bag structure of an aerostat and the aerostat. The multi-air-column bag structure comprises an external air bag, and further comprises helium columns and air columns which are arranged in the external air bag in parallel; a plurality of helium columns and a plurality of air columns are arranged; each helium column comprises a helium column-shaped air bag, a first air duct and a helium valve; each air column comprises a column type air bag, a second air duct, an air valve and a third air duct. By opening and closing helium valves and air valves, the air pressure in the helium columns and the air columns is adjusted, the helium columns and the air columns bear the main gas pressure difference, and the internal and external air pressure difference borne by the external air bag is greatly reduced; the maximum radiuses of the helium columns and the air columns are greatly reduced relative to the maximum radius of the external air bag, and the maximum stress of the helium columns and the maximum stress of the air columns are much smaller than the maximum stress of the external air bag of the aerostat; and each helium column can be independently controlled through the corresponding second air duct and the corresponding air valve, the overall airtight safety of helium storage can be improved, and then the overall airtightness of the aerostat is improved.

    本发明公开了一种浮空器的多气柱囊体结构和浮空器,包括外部气囊,还包括并列设置在外部气囊内部的氦气柱和空气柱;氦气柱和空气柱均设置有若干个;每个氦气柱包括氦气柱状气囊、第一风道和氦气阀门;每个空气柱包括柱型空气囊,第二风道、空气阀门和第三风道。本发明通过开、闭氦气阀门和空气阀门,进而来调节氦气柱和空气柱内的气压,氦气柱和空气柱承受主要气体压力差,大大减少外部气囊受的内外气压差;且氦气柱和空气柱相对于外部气囊的最大半径减少很多,氦气柱和空气柱的最大应力比浮空器外部气囊的最大应力小很多;且每一个氦气柱都能通过第二风道、空气阀门独立控制,可提高氦气存贮整体气密安全性,进而提高浮空器整体气密性。
