Book excerpt: The Department of Energy (DOE) and the NASA Glenn Research Center are developing a Stirling converter for an advanced radioisotope power system to provide spacecraft onboard electric power for NASA deep space missions. This high-efficiency converter is being evaluated as an alternative to replace the much lower efficiency radioisotope thermoelectric generator (RTG). The current power requirement (six years after beginning of mission (BOM) for a mission to Jupiter) is 210 W(sub e) (watts electric) to be generated by two separate power systems, one on each side of the spacecraft. Both two-converter and four-converter system designs are being considered, depending on the amount of required redundancy.Juhasz, Albert J. and Tew, Roy C. and Thieme, Lanny G.Glenn Research CenterSPACECRAFT POWER SUPPLIES; POWER CONVERTERS; SYSTEMS ENGINEERING; RADIOISOTOPE BATTERIES; RESEARCH AND DEVELOPMENT; STIRLING CYCLE; SPACE MISSIONS; THERMOELECTRIC GENERATORS

This book was released on 2008-01-31 with total page 1206 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the British, French and Spanish Atlantic empires were torn apart in the Age of Revolution, Portugal steadily pursued reforms to tie its American, African and European territories more closely together. Eventually, after a period of revival and prosperity, the Luso-Brazilian world also succumbed to revolution, which ultimately resulted in Brazil's independence from Portugal. The first of its kind in the English language to examine the Portuguese Atlantic World in the period from 1750 to 1850, this book reveals that despite formal separation, the links and relationships that survived the demise of empire entwined the historical trajectories of Portugal and Brazil even more deeply. From constitutionalism to economic policy to the problem of slavery, Portuguese and Brazilian statesmen and political writers laboured under the long shadow of empire as they sought to begin anew and forge stable post-imperial orders on both sides of the Atlantic.

This book was released on 2018-06-20 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Energy (DOE) and NASA have identified Stirling Radioisotope Generators (SRG) as a candidate power system for use on long-duration, deep-space science missions and Mars rovers. One of the developments planned for an upgraded version of the current SRG design is to achieve higher efficiency by increasing the overall operating temperature of the system. Currently, the SRG operates with a heater head temperature of 650 C and is fabricated from the nickel base superalloy 718. This temperature is at the limit of Alloy 718's capability, and any planned increase in temperature will be contingent on identifying a more capable material from which to fabricate the heater head. To this end, an assessment of material candidates was performed assuming a range of heater head temperatures. The chosen alternative material candidates will be discussed, along with the development efforts needed to ensure that these materials can meet the demanding system requirements of long-duration operation in hostile environments.

This book was released on 1994 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper presented at the 45th Congress of the IAF in Jerusalem, Israel, October 1994. The paper describes the results of a DOE-sponsored design study of a radioisotope thermophotovoltaic generator (RTPV), to complement similar studies of Radioisotope Thermoelectric Generators (RTGs) and Stirling Generators (RSGs) previously published by the authors. To focus the design effort, it was decided to direct it at a specific illustrative space mission, Pluto Fast Flyby (PFF). That mission, under study by the JPL, envisages a direct eight to nine-year flight to Pluto (the only unexplored planet in the solar system), followed by comprehensive mapping, surface composition, and atmospheric structure measurements during a brief flyby of the planet and its moon Charon, and transmission of the recorded science data to Earth during a six-week post-encounter cruise.
