Download or read book Structural Dynamics Experimental Activities in Ultra lightweight and Inflatable Space Structures written by Richard S. Pappa and published by . 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 2000 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses photogrammetric measurements of a 5m-diameter inflatable space antenna using four Kodak DC290 (2.1 megapixel) digital cameras. The study had two objectives: 1) Determine the photogrammetric measurement precision obtained using multiple consumer-grade digital cameras and 2) Gain experience with new commercial photogrammetry software packages, specifically PhotoModeler Pro from Eos Systems, Inc. The paper covers the eight steps required using this hardware/software combination. The baseline data set contained four images of the structure taken from various viewing directions. Each image came from a separate camera. This approach simulated the situation of using multiple time-synchronized cameras, which will be required in future tests of vibrating or deploying ultra-lightweight space structures. With four images, the average measurement precision for more than 500 points on the antenna surface was less than 0.020 inches inplane and approximately 0.050 inches out-of-plane.

Download or read book Solar Sails written by Giovanni Vulpetti and published by Springer. This book was released on 2014-11-05 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reality of sunlight-based sailing in space began in May 2010, and solar sail technology and science have continued to evolve rapidly through new space missions. Using the power of the Sun's light for regular travel propulsion will be the next major leap forward in our journey to other worlds. This book is the second edition of the fascinating explanation of solar sails, how they work and how they will be used in the exploration of space. Updated with 35% new material, this second edition includes three new chapters on missions operated by Japan and the US, as well as projects that are in progress. The remainder of the book describes the heritage of exploration in water-borne sailing ships and the evolution to space-vehicle propulsion; as well as nuclear, solar-electric, nuclear-electric and antimatter rocket devices. It also discusses various sail systems that may use either sunlight or solar wind, and the design, fabrication and steering challenges associated with solar sails. The first edition was met with overwhelmingly positive reviews, and deemed “a title that needs to be on your shelf if you’re seriously interested in the next step as we move beyond rocketry" (Centauri Dreams, September 2008). Written with a mixed approach, this book appeals to both the general public as well as those with a more scientifically technical background.

Book excerpt: In March 2000, NASA's Office of Space Flight asked the Aeronautics and Space Engineering Board of the National Research Council to perform an independent assessment of the space solar power program's technology investment strategy to determine its technical soundness and its contribution to the roadmap that NASA has developed for this program. The program's investment strategy was to be evaluated in the context of its likely effectiveness in meeting the program's technical and economic objectives.
