摘要

据信，火箭的使用将给微卫星开发商提供优先服务，从而彻底改变航天工业，而微卫星开发商现在是大型火箭公司的次要有效载荷。然而，包括火箭在内的平流层气球通常都是用氦气填充的，氦气的价格在过去十年中急剧上涨，如果这种趋势继续下去，氦气在这项技术中的使用可能会受到严重损害。在这里，我们首次评估了氦气封闭浮力系统的可能性，在该系统中，氦气储存在与平流层气球相连的加压罐中，并通过离心泵将氦气泵入气球并将其泵出。初步计算表明，使用碳纤维增强聚合物(CFRP)复合材料作为储存容器的材料，需要直径约4.5米的容器来运输总质量为150公斤的小型火箭。氦气封闭浮力系统不仅可以节省氦气，还可以在提升和着陆过程中控制浮力。关键词:Rockoon，氦气平流层气球，氦气市场

A rockoon closed helium buoyancy system; a first assessment

It is believed that the use of rockoons will revolutionize the space industry by giving priority service to microsatellite developers that now are secondary payloads for large rocket companies. However, stratospheric balloons, including rockoons, are typically filled with helium, the price of which has been rising sharply in the last decade, and if the tendency continues the use of helium in this technology could be seriously compromised. Here, we present a first assessment of the possibility for a helium closed buoyancy system in which helium is stored in a pressurized tank attached to the stratospheric balloon and pumped into the balloon and back by means of a centrifugal pump. Preliminary reckoning shows that by using a carbon-fiber-reinforced polymers (CFRP) composite as material for the storage vessel, a vessel diameter around 4.5 m will be necessary to transport a small rocket with a total mass of 150 kg. A helium closed buoyancy system will allow not just saving helium but also controlled buoyancy during lifting and the landing. Keywords: Rockoon, Helium Stratospheric Balloons, Helium Market

期刊介绍： The Journal of the British Interplanetary Society (JBIS) is a technical scientific journal, first published in 1934. JBIS is concerned with space science and space technology. The journal is edited and published monthly in the United Kingdom by the British Interplanetary Society. Although the journal maintains high standards of rigorous peer review, the same with other journals in astronautics, it stands out as a journal willing to allow measured speculation on topics deemed to be at the frontiers of our knowledge in science. The boldness of journal in this respect, marks it out as containing often speculative but visionary papers on the subject of astronautics.
