During the period of 2012 through 2015, RSC Energia, on its own initiative, within the framework of investment project Development of a Prototype Transformable Habitable Space Module, conducted an independent effort to design transformable modules, as well as to construct and perform ground developmental testing of a scale model of a transformable module. The test program was intended to verify and confirm the chosen design and layout solutions with respect to functioning, pressure integrity, strength of the product, as well as to acquire data about amplitude frequency response of the transformable shell. The paper presents descriptions of the tests that have been conducted, their objectives and achieved results, it describes experimental facilities and procedures for the tests. It draws conclusions based on the results produced by the effort, and outlines ways and options for further developmental testing on the mockup of the transformable module. Key words: transformable module, multilayer transformable pressurized shell, experimental development, testing.
The paper discusses the current status of work to extend the life of the International Space Station Russian Segment (ISS RS). The effort to monitor and maintain the ISS RS systems and modules in good working order forms the basis of the work aimed at station longevity and the safety of its crew. It describes measures taken to keep the ISS RS operational in a situation where some of the components have been taken out of production, and specified storage life for the spares, tools and accessories has expired. It reviews changes in the requirements for the operation of constituent components, systems and assemblies that were adopted to support extension of the ISS RS mission. It describes a procedure for detecting the sources of failures and malfunctions found in flight and resolving their causes, which makes it possible to take measures aimed at preventing propagation of faults and malfunctions within the shortest time possible while keeping the systems and assemblies of the ISS RS modules operational during repairs. It describes an approach to analysis of the causes of component failures, which makes it possible to classify them for the purposes of statistical analysis, on the basis of which one could evaluate failure dynamics in the course of the mission and use it for making a conclusion about the feasibility of extending flight tests of the ISS RS till 2024 and further. It provides data on dynamics of changes in the number of component failures in the course of the ISS RS mission, which show that this number does not grow. Key words: International Space Station, ISS RS, Russian Segment, operational integrity, operating life, failures.
The paper presents the results of an independent design study into the feasibility of developing for the Super-Heavy Space Rocket (SHSR) with 140–170 ton payload capacity a modular Launch Vehicle (LV) in the form of a tri-pack cluster of three two-stage medium LVs Soyuz-5 and three side-mounted bi-pack clusters based on coupling together the first stages of LV Soyuz-5 based on NPO Energomash oxygen-kerosene main engines RD171MV, RD180, RD191M and a four-chamber version of the RD120 engine. In addition to this, the paper discusses the feasibility of using the tri-pack cluster from the SHSR as a standalone Heavy LV with an increased payload capacity (50–60tons) to assure its more frequent use, and thus upkeep the operational reliability of the more powerful SHSR. The paper demonstrates the feasibility of designing the second-phase reusable versions of the first-stage clusters for SHSR and Heavy LV, as well as the feasibility of manned lunar missions using not two, but only one SHSR. Key words: integrated launch vehicle, launch vehicle, main engine, tri-pack cluster, bi-pack cluster, crew transportation spacecraft, lunar take-off and landing vehicle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
