Satellites - Gas system for electric propulsion

Preparing the next generation of launch vehicles

我们参与了阿丽亚娜1号到阿丽亚娜5号的设计阶段cryogenic propellant tanks直到他们被安装到欧洲火箭上。这些技术的发展坦克，以及insulation某些设备，比如按ure Control Unitsor thelevel gauges，使我们能够取得惊人的技术进步。我们现在以欧洲航天局（ESA）的身份与之合作低温专家.WithEuro Cryospace，这是液化空气公司与空客国防和航天公司之间的战略合作伙伴关系，我们提供的创新解决方案是对未来阿丽亚娜6号运载火箭概念的体验，该运载火箭将具有重燃能力。

• 360低温罐since 1979
• 6 generationsof European launch vehicles
• 150 kg additional payload capacity多亏了LHESS

未来十年，在轨物体的数量将增加。以及400颗新卫星dedicated toEarth observationand其他300人专门从事电信业务，人们已经在谈论发射超过1000颗额外的卫星，使有史以来最大的星座环绕地球！

多亏了它在orbital cryogenics,存储系统and气体分布,Air Liquide will be part of this revolution. The group has already been able to meet a wide variety of needs like the生物样品的保存in the国际空间站的梅尔菲冷冻柜，的宇宙背景热辐射的观测with the Planck and Herschel satellites, and the观测卫星红外探测器的冷却. 通过提供我们的专业知识，并将我们的技术添加到“好奇”号和“外火星”探测器上，我们也参betway旗舰版下载与了探索火星.

• 80000转per minute for the last 10 years for the MELFI turbo-engine
• 0.1 Kelvin：普朗克探测器绝对零度以上十分之一度
• 2400升容量对于Herschel's helium tank, kept at 1.6 Kelvin

Air liquide has been preparing, testing, and optimizing the installation and connections ofcryogenic lines for launch pads自上世纪80年代以来，我们在圭亚那库鲁、美国卡纳维拉尔角、日本种子岛以及中国西昌和文昌的航天发射场开展业务。

我们提供了液氢和液氧装置产生cryogenic fluids for launch vehiclesin Kourou. Several Air Liquide employees are based on the Guiana Space Center in order to supply液氢和液氧对于thelaunch vehicles' propulsion,液氮对于inerting，和氦这对我们来说是必不可少的加压、冷却和清洁.这个y also deal with equipment maintenance for Arianespace and the CNES.

我们还提供直升机氦和叶肉氢气液化器对于these space centers. The HELIAL in Kourou, for example, liquefies helium gas vapor that evaporates during storage.

Moreover, we have designed模拟室and试验台在地面上复制extreme space conditionsthat satellites and their components are subjected to.

• 2 Ariane cryogenic launch库鲁复合物
• 数公里的真空绝热低温管线to fill Ariane's tanks with propellants on the launch pad

Air Liquide offers industrial and scientific customers the use of a test center that is unique in Europe, with the expertise of a dedicated team at their disposal. This占地6公顷，位于格勒诺布尔附近,was built in order to test, inspect, and qualify equipment for the needs of the space industry. Our team has acquired a high level of expertise in all kinds of studies, from thecharacterization of materials, to thermal cycle analysis, cryogenic trials, and the simulation of thermal conditions on the ground, during take-off, and in space…

液化空气公司也在其测试中心外进行试验，脉冲管制冷机就是这样，它是在一个超洁净的房间里进行检查的。有时实验甚至可以在离萨森纳格很远的地方进行，比如在瑞典的极地圈内进行的Cryofenix试验。

建立一个基地和生活在太空不再是just a pipe dream. The European Space Agency may have plans to set up a permanent base on the moon, which could eventually replace the International Space Station and be used as a stepping-stone to Mars. Solutions for putting this incredible project into action already exist. What would we need in order to live far from Earth? We would need to produce and store energy, to purify air, and to produce fuel to enable spacecraft to return to Earth…

在液化空气集团，我们正在认真考虑如何为establishing human life in space.We have already developed all the technological building blocks required for this new adventure for terrestrial applications:燃料电池、空气净化装置、推进剂生产系统,etc. All that remains is to adapt them for use in space. Thanks to more than 50 years' experience in the conquest of space, we are up to the challenge. We have all the necessary expertise, recognized the world over, and are ready to test these technologies on the “Lunar Analogue” facility, under construction at the European Astronaut Centre in Germany. Today, living on the moon is much more than just a dream. Tomorrow, it will become a reality.
