The invention discloses a buoyancy control device for long-endurance fixed-height flight of an aerostat. A liquid helium Dewar is hoisted below a floating air bag through a pull rope, a helium outlet is formed in the liquid helium Dewar, an air supply port is formed in the floating air bag, the helium outlet is communicated with the air supply port through an air supply pipe, and the liquid helium Dewar is used for supplying air to the floating air bag through the air supply pipe. According to the buoyancy control device for the long-endurance fixed-height flight of the aerostat, the liquid helium Dewar is carried, so that the buoyancy of the aerostat can be controlled for multiple times, the long-endurance fixed-height flight of the aerostat can be guaranteed, meanwhile, the buoyancy control device is easy to install, an additional power supply or chemical device is not needed, and the influence on the load capacity of the aerostat is small.
本发明公开了一种用于浮空器长航时定高度飞行的浮力控制装置,液氦杜瓦通过拉绳吊装在浮空气囊下方,液氦杜瓦上设有氦气出口,浮空气囊上设有补气口,所述氦气出口和所述补气口之间通过供气管连通,液氦杜瓦用于通过供气管为浮空气囊补气。通过上述优化设计的用于浮空器长航时定高度飞行的浮力控制装置,通过搭载液氦杜瓦,可以实现多次对浮空器浮力的控制,能够保障浮空器长航时定高度飞行,同时易于安装,无需额外电源或化学装置,对浮空器负载能力的影响较小。
