Large transformable structures for advanced manned complexes

Since 2012 RSC Energia, within the framework of investment project Development of a Prototype Transformable Habitable Space Module has been conducting independent design work on transformable modules, construction and developmental testing of a scale model of a transformable module and fragments of a multilayer transformable pressurized shell. The paper covers main results of the work completed under the project, including tests of fragments of a multilayer transformable pressurized shell, selection of the micrometeoroid protection design and its developmental testing, manufacturing and ground testing of a scale mockup of the transformable module. In addition to this, the paper describes the outlook for further implementation of the project to develop a mid-sized experimental transformable module, as well as to use the developed technology of inflatable transformable modules in the interests of development of the Russian manned space flight.
