When it comes to our enterprise in space, the desire for short-term benefits and fulfillment often clouds our perception and appreciation of any long-term societal impact. Too often, exploration is seen as a means to the technologies, or ''spin-offs,'' that can be transferred to the private sector. The opposite is true. For a space program, technology is the means to the end that is more exploration...
The Intelligent Synthesis Environment (ISE), which is one of the major strategic technologies under development at NASA centers and the University of Virginia, is described. One of the major objectives of ISE is to significantly enhance the rapid creation of innovative affordable products and missions. ISE uses a synergistic combination of leading-edge technologies, including high performance computing,...
A power processing system design for a space-type high power (200W RF) multi-stage depressed collector traveling wave tube is described. Operating requirements are set forth and a block diagram is presented illustrating the overall approach used in providing the requisite outputs. The basic power circuit is illustrated and overall performance, design characteristics and unique features are discussed.
Projections of future spacecraft operational characteristics indicate that power conditioning requirements will become extremely demanding with respect to output power level, regulation, control, sequencing, and reliability. New approaches for design of power conditioning equipment capable of meeting such requirements are currently under development at a number of government and contractor laboratories...
