FlexLine
FlexLine is a standardised product family of carbon composite outer structures for Small (Satellite) Launch Vehicles (SLV). It comprises Payload Fairings and Interstage Adapters (stage separation mechanism modules) with confectioned outer diameters sizes 0.70m, 1.20m, 1.50m, 1.80m and 2.00m. This standard is proposed and developed by RUAG Schweiz AG, RUAG Space, initially published on the 15th Reinventing Space Conference 2017 in Glasgow. The companies developing rockets for small satellite launch services represent a new industry in space technology sector. With over 100 worldwide projects and intentions (January 2019) it is expected that launch services for small satellites will be available in many world regions and launch sites. This is likely to boost the use of miniaturized satellites and small satellite constellations. This industry seeks in turn commercially available subsystem for their rockets similar to the supply chain e.g. in the automotive industry. The standard established by RUAG Space in form of the FlexLine product family follows the demand of many original equipment manufacturers (OEM) of space rockets. This demand is centered around following needs:


 * pyro-technical and debris-free separation and jettison systems
 * monolithic monocoque shells design
 * integrated launch vehicle interfaces
 * plug-and-play modules for easy integration and handling
 * low shock separations
 * variable length versions for payload mission adaptation
 * prepared for re-usability
 * short lead times
 * worldwide delivery

FlexLine products are available since 2018 (first sizes) whilst the full products range is completed in years 2019 and 2020. The FlexLine products mark a milestone in space technology for the new space era as being standardized modules trimmed to best-in-class cost level, benchmarked with products from other non-space industry sectors, as e.g. automotive sector. They offer adequate low cost, fast time-to-market and high reliability to the small launch vehicle industry. The emerging traffic system to earth orbit is supported economically by this kind of commercialized products.
