| Popis: |
Low cost access to space achievable with next generation launchers needs that cryogenic insulations, as a part of an highly reusable thermo-mechanical architecture, are able to withstand without significant degradation critical environments experienced especially during pre-launch and re-entry phases. Considerable effort is presently focused worldwide on the technology development of reusable insulating systems applied to cryogenic tanks for liquid propulsion. In the frame of a contract funded by ESA, Alenia Spazio is carrying out an extensive characterization campaign to improve performances of available insulations that only partially sustain thermo-mechanical loads and met physico-chemical requirements imposed by the operative environment. The campaign is divided in two different slices. The first one has the objective to identify the best insulation material and the relative configuration satisfying typical requirements of a Reusable Launcher Vehicle (RLV) mission; the second one is devoted to the execution of a test representative of the flight conditions performed on a sub-scale Aluminum Lithium tank insulated with the selected material to verify the capability of the tank-insulation system to sustain operative thermo-mechanical loads after repeated cycles. |
