The invention discloses a volume-controllable airbag device and a multi-airbag airship system. The volume-controllable airbag device comprises an airbag, a storage tank and a conversion device, wherein the airbag is used for storing a gaseous medium; the storage tank is used for storing a liquid medium or a solid medium; when there is no sunlight, the overall buoyancy of the airship is reduced, the conversion device converts the liquid medium or the solid medium in the storage tank into the gaseous medium and fills the airbag with the gaseous medium, so that the size of the airbag is increased, and the buoyancy is improved; when there is sunlight, the overall buoyancy of the airship is increased, the conversion device converts the gaseous medium in the airbag into the liquid medium or thesolid medium, the size of the airbag is reduced, and the buoyancy is reduced. According to the volume-controllable airbag device and the multi-airbag airship system provided by the invention, the buoyancy is controlled by introducing the additional phase-change airbag, buoyancy changes of the airship caused by external factors such as existence of illumination in a stratospheric environment is balanced, and the realization of an airship capable of staying in the stratosphere for a long time is facilitated.
一种体积可控气囊装置及多元气囊飞艇系统,体积可控气囊装置包括气囊、储存罐以及转换装置;气囊用于存储气态介质,储存罐用于存储液态介质或者固态介质;无日照时,飞艇整体浮力降低,转换装置将储存罐中的液态介质或者固态介质转换为气态介质并填充至气囊中使气囊的体积变大,以提高浮力;有日照时,飞艇整体浮力增加,转换装置将气囊中的气态介质转换为液态介质或者固态介质,使气囊的体积变小,以降低浮力。本发明提供的体积可控气囊装置及多元气囊飞艇系统,通过引入附加相变气囊操控浮力,平衡飞艇在平流层环境下因光照有无等外界因素引起的浮力变化,有利于可长时驻空平流层飞艇的实现。
