At DLR a multidisciplinary research project called AKIRA (in English: specific critical technologies and integrated system investigations for RLV applications) is ongoing. Reusable cryo-tank insulation is one of the key-challenges and is in focus of AKIRA. A preferred reusable insulation concept is defined which subsequently is assembled as an Integrated Test Object (ITO) to be tested in DLR’s facilities under relevant conditions. This ITO, to be built at various sizes, is combining a cryogenic fluid compartment, reusable insulation, external thermal insulation as well as sensors for data acquisition and health monitoring. The paper provides an overview of the ongoing activities in enhancing RLV tank insulation and summarizes major research results available. The ITO concept is described and the impact of this design on a full scale reusable launcher stage is discussed.
