Book excerpt: The first phase of this project was completed in March 2000, and included the successful technology demonstration of a new ultralightweight photovoltaic concentrator array at the fully functional panel level. The new array is called the Stretched Lens Aurora (SLA) array, and uses deployable, flexible, thin-film silicone rubber Fresnel lenses to focus sunlight onto high efficiency multijunction solar cells, which are mounted to a composite radiator surface for waste heat dissipation. A prototype panel was delivered to NASA Marshall in March 2000, and comprised four side-by-side lenses focussing sunlight onto four side-by-side photovoltaic receivers. This prototype panel was tested by NASA Glenn prior to delivery to NASA Marshall. The best of the four lens/receiver modules achieved 27.4% efficiency at room temperature in the NASA Glenn solar simulator tests. This performance equates to 375 W/sq.m. areal power and 378 W/kg specific power at the fully functional panel level. We believe this to be the first space solar array of any kind to simulataneously meet the two long-standing NASA goals of 300 W/sq.m. and 300 W/kg at the functional panel level. Key results for the first phase of the program have been documented by ENTECH in a Draft Final Technical Report, which is presently being reviewed by NASA, and which should be published in the near future.

Book Synopsis Fresnel Concentrators for Space Solar Power and Solar Thermal Propulsion by : National Aeronautics and Space Administration (NASA)
Download or read book Fresnel Concentrators for Space Solar Power and Solar Thermal Propulsion written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-16 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large deployable Fresnel concentrators are applicable to solar thermal propulsion and multiple space solar power generation concepts. These concentrators can be used with thermophotovoltaic, solar thermionic, and solar dynamic conversion systems. Thin polyimide Fresnel lenses and reflectors can provide tailored flux distribution and concentration ratios matched to receiver requirements. Thin, preformed polyimide film structure components assembled into support structures for Fresnel concentrators provide the capability to produce large inflation-deployed concentrator assemblies. The polyimide film is resistant to the space environment and allows large lightweight assemblies to be fabricated that can be compactly stowed for launch. This work addressed design and fabrication of lightweight polyimide film Fresnel concentrators, alternate materials evaluation, and data management functions for space solar power concepts, architectures, and supporting technology development.

Book Synopsis The Artemis Lunar Program by : Manfred “Dutch” von Ehrenfried
Download or read book The Artemis Lunar Program written by Manfred “Dutch” von Ehrenfried and published by Springer Nature. This book was released on 2020-05-12 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the future of the Artemis Lunar Program from the years 2017 to about 2030. Despite the uncertainty of the times and the present state of space exploration, it is likely that what is presented in this book will actually happen, to one degree or another. As history has taught us, predictions are often difficult, but one can see enough into the future to be somewhat accurate. As the Bible says, “Wesee thru the glass, but darkly.” All of the elements of the proposed program are described from several perspectives: NASA’s, the commercial space industry and our International partners. Also included are descriptions of the many vehicles, habitats, landers, payloads and experiments. The book tells the story of the buildup of a very small space station in a strange new lunar orbit and the descent of payloads and humans, including the first women and next man, to the lunar surface with the intent to evolve a sustained presence over time.
