Energy Conversion for Space Power by Nathan Snyder Pdf

Progress in Astronautics and Rocketry, Volume 3: Energy Conversion for Space Power focuses on the use of dependable electric power sources on space vehicles. Composed of various literature, the book first discusses the physics of thermoelectricity, thermoelectric generator of materials, the use of semiconductors in thermoelectric conversion, and the use of high temperature thermoelectric materials for power generation. The text also presents experiments on the effect of irradiation on thermoelectric materials, thermoelectric elements in space power systems, and thermionics. The book then describes photovoltaic effect and conversion of solar energy; trends in silicon solar cell technology; the use of silicon solar cells in energy conversion; and how radiation affects solar cell power systems. The text notes the specifications of batteries if used in communications satellites; the use of positive-displacement engines and turbines on cryogenic power systems; and the characteristics of magnetohydrodynamic (MHD) generators in space power conversion. The book is a good source of information for readers and scientists wanting to explore the potential of energy conversion in space power technology.

Solar Energy Conversion II by A. F. Janzen,R. K. Swartman Pdf

Solar Energy Conversion II presents the proceedings of the 1980 International Symposium on Solar Energy Utilization, held in Ontario, Canada on August 10-24, 1980. This book provides information on the utilization of solar energy and on the difficulties encountered in its implementation. Organized into 42 chapters, this compilation of papers begins with an overview of the important parameter in solar radiation measurement. This text then examines the use of solar radiation measurement, the solar radiation scales, the solar radiation units, and the types of solar radiation. Other chapters consider the general problems linked with building up data banks of observed solar radiation data. This book discusses as well the fundamental modes of heat transfer. The final chapter deals with the necessity to incorporate energy education into other disciplines like space geometry. This book is a valuable resource for politicians, government officials, engineers, scientists, and research workers. Technologists working on solar energy will also find this book useful.

Solar power satellites. by Anonim Pdf

During energy crisis at the end of the Sixties, a new idea to exploit solar energy arose: Solar Power Satellites. These satellites need a huge surface to collect enough solar energy to be beamed on Earth by means of a microwave power transfer system. Different concepts appeared during last forty years and a lot of studies addressing the SPS economical feasibility have been published. In this work a particular concept is considered, the JAXA Reference Concept 2003. It is a formation flying SPS, composed by two reflectors and a central array panel. The objective of the work is to study two major problems this concept presents. Due to its dimensions, the satellite orbit will suffer from important orbital perturbations and since formation flying satellites need a tight orbit control, the first task is to derive an analytical approximation to perform relative perturbed orbit propagation for formation flying satellite. This objective is pursued starting from a H. Schaub’s formulation in which formation flying satellites unperturbed orbit is described by means of an approximated relation function of orbital element differences. This formulation is merged with another approach, developed in a previous work, which gives, analytically, orbital parameters variation when a perturbation acts on the spacecraft. The result is a very interesting algorithm, able to perform the assigned task with a relative error lower than 3% over one simulated orbit. The second objective concerns structural control. It is not possible to consider these huge satellites as rigid bodies, first natural frequencies will be certainly excited during operations. So that, the second task is the study of actuator placement optimization for flexible satellites, very useful for tight pointing requirements. A FEM model is developed modeling the SPS as a frame of beams and a global controllability index is obtained combining modal controllability and component cost analysis. The maximization of this parameter,

Solar Power from Satellites by Committee on Aeronautical and Space Sciences,Committee on Aeronautical and Space Scie,United States Senate Pdf

A look at ways to collect solar power in space with satellites and beam that power down to Earth to supplement our other sources of electricity. In addition, this is a look at novel ways, to say the least, to construct those satellites. The witnesses at these Senate hearings envision a time when space will be the scene of bustling activity. They foresee construction of gigantic facilities that will provide the world with energy, which is an essential and increasingly costly part of our industrial society.

Linear Energy Transfer Spectra and Dose Equivalents of Galactic Radiation Exposure in Space by Hermann J. Schaefer Pdf

In assessing the astronaut's exposure from galactic cosmic rays on space missions of long duration conversion of absorbed doses to dose equivalents is required. Since a large part of the dose contribution from heavy primaries is produced at Linear Energy Transfer (LET) values beyond the range for which radiobiological data are available, it seems preferable to analyze the LET distributions themselves and to compare them to standard x-rays rather than to assume arbitrary values for the Relative Biological Effectiveness(RBE). The local LET distributions in tissue are found to be extremely skewed, with a large maximum at the relativistic minimum LET. Lined up on the LET scale, they cover the very wide interval from 0.18 to 2790 kev/micron T as compared to an interval from 0.4 to 35 kev/micron T for standard x-rays. Applying the RBE formula of the RBE Committee of the ICRP and a saturation value of 10 leads to a grand mean RBE of 1.82 for the total absorbed dose of 13 millirads/24 hours from primaries.

Solar Energy Conversion Systems by Jeffrey R. S. Brownson Pdf

Solar energy conversion requires a different mind-set from traditional energy engineering in order to assess distribution, scales of use, systems design, predictive economic models for fluctuating solar resources, and planning to address transient cycles and social adoption. Solar Energy Conversion Systems examines solar energy conversion as an integrative design process, applying systems thinking methods to a solid knowledge base for creators of solar energy systems. This approach permits different levels of access for the emerging broad audience of scientists, engineers, architects, planners, and economists. Traditional texts in solar energy engineering have often emerged from mechanical or chemical engineering fields. Instead, Solar Energy Conversion Systems approaches solar energy conversion from the perspectives of integrative design, environmental technology, sustainability science, and materials science in the wake of amazing new thin films, polymers, and glasses developed by the optoelectronics and semiconductor industries. This is a new solar text for the new generation of green job designers and developers. It’s highlighted with vignettes that break down solar conversion into useful stories and provides common points of reference, as well as techniques, for effective estimation of evolving technologies. Contextualizes solar conversion for systems design and implementation in practical applications Provides a complete understanding of solar power, from underlying science to essential economic outcomes Analytical approach emphasizes systems simulations from measured irradiance and weather data rather than estimations from "rules of thumb" Emphasizes integrative design and solar utility, where trans-disciplinary teams can develop sustainable solar solutions that increase client well-being and ecosystems services for a given locale
