This book was released on 2018-06-30 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a technical audit of the Space Station Freedom Program conducted by the Program Director was announced in early 1989 and included a proposal to use solar dynamic power generation systems to provide primary electrical energy for orbital flight operations rather than photovoltaic solar array systems. To generate the current program baseline power of 75 kW, two or more solar concentrators approximately 50 feet in diameter would be required to replace four pairs of solar arrays whose rectangular blanket size is approximately 200 feet by 30 feet. The photovoltaic power system concept uses solar arrays to generate electricity that is stored in nickel-hydrogen batteries. The proposed concept uses the solar concentrator dishes to reflect and focus the Sun's energy to heat helium-xenon gas to drive electricity generating turbines. The purpose here is to consider the station configuration issues for incorporation of solar dynamic power system components. Key flight dynamic configuration geometry issues are addressed and an assembly sequence scenario is developed. Deryder, L. J. and Cruz, J. N. and Heck, M. L. and Robertson, B. P. and Troutman, P. A.

Available in PDF, EPUB and Kindle. Book excerpt: The National Aeronautics and Space Administration (NASA) has selected a closed Brayton cycle (CBC) solar dynamic (SD) power conversion system to provide electric power for the growth phase of Space Station Freedom. This selection was based in part on the comparitive reduction in solar radiation collection made possible by the high efficiency, closed Brayton cycle system when compared to the efficiency of static conversion systems. The smaller required collector area results in a significant reduction in drag in the low earth orbit which is planned for the Space Station. Under contract to the Rocketdyne Division of Rockwell International, the Allied-Signal Aerospace Company, Garrett Fluid Systems Division is developing the Solar Dynamic Power Generating Subsystem (PGS). This subsystem consists of a solar receiver, which accepts sunlight from the multifaceted collector mirror (the concentrator), and a CBC heat engine that converts the solar heat into electricity. This paper will review the design requirements for the Space Station Solar Dynamic Power Module and present results of the PGS cycle analysis and preliminary design.

Download or read book Space Station Freedom Solar Dynamic Modules Structural Modelling and Analysis written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-11 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: In support of the Space Station Freedom (SSF) Solar Dynamic Power Module effort, structural design studies were performed to investigate issues related to the design of the power module, its pointing capabilities, and the integration of the module into the SSF infrastructure. Of particular concern from a structural viewpoint are the dynamics of the power module, the impact of the power module on the Space Station dynamics and controls, and the required control effort for obtaining the specified Solar Dynamic Power Module pointing accuracy. Structural analyses were performed to determine the structural dynamics attributes of both the existing and the proposed structural dynamics module designs. The objectives of these analyses were to generate validated Solar Dynamic Power Module NASTRAN finite element models, combine Space Station and power module models into integrated system models, perform finite element modal analyses to assess the effect of the relocations of the power module center of mass, and provide modal data to controls designers for control systems design.

This book was released on 2018-07-11 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar dynamic power systems have a higher thermodynamic efficiency than conventional photovoltaic systems; therefore they are attractive for long-term space missions with high electrical power demands. In an investigation conducted in support of a preliminary concept for Space Station Freedom, an approach for a solar dynamic power system was developed and a number of the components for the solar concentrator were fabricated for experimental evaluation. The concentrator consists of hexagonal panels comprised of triangular reflective facets which are supported by a truss. Structural analyses of the solar concentrator and the support truss were conducted using finite-element models. A number of potential component failure scenarios were postulated and the resulting structural performance was assessed. The solar concentrator and support truss were found to be adequate to meet a 1.0-Hz structural dynamics design requirement in pristine condition. However, for some of the simulated component failure conditions, the fundamental frequency dropped below the 1.0-Hz design requirement. As a result, two alternative concepts were developed and assessed. One concept incorporated a tetrahedral ring truss support for the hexagonal panels: the second incorporated a full tetrahedral truss support for the panels. The results indicate that significant improvements in stiffness can be obtained by attaching the panels to a tetrahedral truss, and that this concentrator and support truss will meet the 1.0-Hz design requirement with any of the simulated failure conditions.
