Book excerpt: Inflatable, rigidizable structures provide a solution to reduce the costs associated with design, fabrication and launch of a space system while simultaneously increasing the deployment reliability and mission success of the system%. This research focused on the follow on design, fabrication, and ground test of the Rigidizable Inflatable Get-Away-Special Experiment (RIGEX). RIGEX is a self-contained experiment that will test the deployment and structural characteristics of three inflatable rigidizable tubes. Once inflated and rigidized, each tube will be excited using piezoelectric transducers in order to collect vibration data for structural characterization. The goal of this research was to collect ground testing data that will later be used in conjunction with actual space flight results in an effort to validate ground testing methodologies.

This book was released on 2004-03-01 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: As greater capability is demanded of space-based assets, their size and complexity are growing. Inflatable, rigidizable structures offer significant improvements in the areas of weight, size, and complexity over traditional mechanically deployed systems. These structures are not well understood and little testing of them has been done in the space environment. Widespread acceptance of these technologies will not be achieved without significant reduction in the risk of using inflatable, rigidizable structures in space. The goal of this experiment is to verify and validate ground testing of small tubular truss structures for use in space. This experiment builds on previous research done in this area to reduce the risks involved in testing inflatable, rigidizable structures in space. The Rigidizable Inflatable Get-Away-Special Experiment (RIGEX) is designed to launch as a self-contained experiment on the Space Shuttle. It will inflate and rigidize three redundant experiments in the open space environment. Once these structures are deployed and rigidized, the experiment will vibrationally excite the deployed structures and record the vibrational response. This thesis produced test equipment that would meet the RIGEX Concept of Operations and conducted testing to gain an understanding of the heating, pressurization, and inflation systems of the RIGEX experiment to avoid mission failure. Appendixes contain the following: system weight tabulations, heating test results, inflation test results, success criteria, DoD SERB briefing slides, system architecture, updated NASA payload accommodations requirements, and inflation system calculations. The accommodation plan defines the technical agreement between NASA/Goddard Space Flight Center (GSFC) and the Getaway Special Canister (GAS) customer concerning the unique information needed for the preparation, flight, and disposition of the GAS payload.

This book was released on 2007 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research is to support the final development of the Rigidizable Inflatable Get-Away-Special Experiment (RIGEX). The RIGEX program is an experimental initial step in developing large-scale rigidizable inflatable structures, which can be utilized in space applications. The primary intent of RIGEX is to verify and validate ground testing of inflation and rigidization methods for inflatable space structures against a zero-gravity space environment. This is performed by designing a Canister for All Payload Ejections (CAPE) experiment to collect data on space rigidized structures for validation of ground testing methods. The results presented in this thesis provide documentation needed to meet the requirements set forth by the National Aeronautics and Space Administration (NASA) for launching a payload into space. This thesis establishes a process for appropriately ground testing the components of RIGEX in an environment similar to space and explains future testing required. Methods for charging and testing the performance of the onboard inflation system are also discussed. Additionally, the steps taken to replace the onboard imaging system are explained. Throughout the course of assembling the RIGEX protoflight model, several complications were encountered and the design was modified, which are presented along with an as-built final assembly drawing package. Lastly, the procedure for handling RIGEX during its future progression is illustrated.

This book was released on 2001 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports recently completed structural dynamics experimental activities with new ultra-lightweight and inflatable space structures (a.k.a., "Gossamer" spacecraft) at NASA Langley Research Center, NASA Marshall Space Flight Center, and NASA Goddard Space Flight Center. Nine aspects of this work are covered: 1) inflated, rigidized tubes, 2) active control experiments, 3) photogrammetry, 4) laser vibrometry, 5) modal tests of inflatable structures, 6) in-vacuum modal tests, 7) tensioned membranes, 8) deployment tests, and 9) flight experiment support. Structural dynamics will play a major role in the design and eventually in-space deployment and performance of Grossamer spacecraft. Experimental research and development such as this is required to validate new analysis methods.

This book was released on 2001 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: As space structures grow in size and complexity, their weight and cost increase considerably. The use of inflatable and rigidizable structures offers drastic improvements in all areas of spacecraft design. The goal of this experiment is to verify and validate ground testing of inflation and rigidization methods for inflatable space structures. The Rigidized Inflatable Get-Away-Special Experiment is an autonomous, self-contained space shuttle experiment that will inflate and rigidize several structures. After inflation, the experiment will perform a structural analysis by exciting the rigidized structures and collecting vibration data. A systems engineering approach is utilized to make design decisions based on a total system and life-cycle perspective.

Available in PDF, EPUB and Kindle. Book excerpt: This book explains how researchers design, prepare, develop, test and fly their science experiments on microgravity platforms before sending them to space. All preparation phases are explained and presented, including aircraft parabolic flights as part of spaceflight preparation. Twenty international authors, all experts in their own microgravity research field, contribute to chapters describing their experience to prepare experiments before space flights. Fields covered are Physical Sciences and Life Sciences. Physical Sciences covers fluid physics (vibration effects on diffusion; red blood cell dynamics; cavitation in microgravity; capillary driven flows) and material sciences (electromagnetic levitator onboard International Space Station). Life Sciences includes human physiology (sampling earlobe blood; human cardiovascular experiments; tumours in space) and neurophysiology (dexterous manipulation of objects in weightlessness).

Available in PDF, EPUB and Kindle. Book excerpt: AFIT is in the process of designing a Space Shuttle experiment designated as the Rigidized Inflatable Get-Away-Special Experiment (RIGEX) to study the effects of microgravity on the deployment of rigidizable composite structures. Once in space, the experiment will inflate and rigidize three composite structures and perform a vibration analysis on each by exciting the tubes using piezoelectric patches and collecting data via an accelerometer. This paper presents the structural and vibration analysis of the RIGEX assembly and inflatable composite tubes using ABAQUS Finite Element Analysis (FEA) software. Comparison of the analysis has been carried out with Eigenvalue/Eigenvector experimentation by means of ping testing. This FEA analysis has been used to verify the natural frequency and structural integrity of the RIGEX support assemblies. The ABAQUS FEA results correlated to within 20% of experimental values.
