Clean & Green in Space

对包括数据、导航和地球观测在内的天基服务的需求日益增长。这需要更多的卫星和相应的发射器。英国的目标是到2030年占世界太空市场收入的10%，按今天的价值计算，价值约为400亿英镑。为支持这一点，联合王国政府正在投入大量资金，以建立世界领先的空间推进系统设计和测试能力。其目的是确保联合王国成为空间推进发展和推进系统制造的主要地点。此外，这将确保英国卫星制造商以及小型发射器制造商能够获得最先进的推进系统。对更高性能和更大数量卫星的需求已经在全球范围内引发了更激烈的竞争，从而推动了对具有竞争力的成本以及包括推进在内的所有系统性能的需求。这反过来又导致对能够提供创新解决方案的新供应商的需求更大，这些解决方案在成本和性能方面挑战现有技术。与此同时，卫星性能正在提高，越来越小的卫星能够提供商业上可行的解决方案，从而为运营商带来收入。这需要更小的燃料箱解决方案和更高的生产率，这再次推动了制造和组装方面的创新需求。影响该项目的最终驱动因素是需要更安全，更少环境破坏的发射器和卫星推进剂。与当前推进剂相关的风险导致非常高的成本。绿色/安全处理推进剂已经开发出来，需要新的优化油箱材料和设计，以确保它们在商业上是可行的和可靠的。TISICS提案旨在开发一种新的隔膜设计，与新的油箱固定装置相结合，这种油箱固定装置明显更轻，生产成本更低，安装更容易，从而降低了卫星发动机的成本和交货时间。这也使TISICS能够为英国的坦克生产设施建立一个投资案例，创造高科技就业机会和潜在的出口收入。英国卫星制造商可以与TISICS及其供应链密切合作，快速优化和交付燃料箱，以满足其卫星和小型发射器的需求，而无需依赖可能存在出口管制和限制的进口技术。TISICS的愿景和动机是通过提供具有成本竞争力的未来绿色推进剂燃料箱来响应这一市场需求。这将使英国航天工业处于未来航天市场的最前沿，创造英国的供应链和就业机会，减少对进口的依赖和与进口相关的成本。

There is a growing demand for space based services including data, navigation and earth-observation. This requires more satellites and consequentially more launchers.The UK is targeting 10% of the world space market revenues by 2030 worth around £40Bn at todays values. To support this the UK Government is investing significant sums to establish a world leading space propulsion system design and test capability. This aims to ensure that the UK is the prime location for space propulsion development and consequentially propulsion system manufacture. Additionally this will ensure that UK satellite manufacturers as well as small launcher manufacturers have access to the most advanced propulsion systems.The need for higher performance and larger numbers of satellites has created increased competition worldwide driving a need for competitive costs as well as performance in all systems including propulsion. This in turn is leading to greater demand for new suppliers capable of providing innovative solutions which challenge the incumbent technologies for both cost and performance.At the same time satellites performance is increasing with much smaller satellites capable of delivering commercially viable solutions and hence revenues for operators. This requires smaller tank solutions and higher production rates which again drives a need for innovation in manufacture and assembly.A final driver which influences this project is the need for safer, less environmentally damaging propellants for launchers and satellites. The risks associated with current propellants lead to very high costs. Green/safe to handle propellants have been developed and need new optimised tank materials and designs to ensure they are commercially viable and reliable.TISICS proposal aims to develop a novel diaphragm design coupled to a new tank fixing which is significantly lighter, cheaper to produce and easier to install reducing cost and lead times for satellite primes. This also enables TISICS to build an investment case for a UK tank production facility which generates high tech jobs and potential export revenues. UK satellite producers can work closely with TISICS and its supply chain to rapidly optimise and deliver tanks to meet their satellite and small launcher needs without reliance on imported technology with potential export controls and restrictions.TISICS vision and motivation is to respond to this market needs by delivering cost competitive future green-propellant tanks. This will get the UK space industry at the forefront of the future space market creating a UK supply-chain and jobs, and reducing dependence and costs associated with imports.
