PDF-(EBOOK)-Fundamentals of Electric Propulsion: Ion and Hall Thrusters

Throughout most of the twentieth century electric propulsion was considered the technology of the future Now the future has arrived This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today ion and Hall thrusters The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance They then go on to present detailed explanations ofThruster principlesIon thruster plasma generators and accelerator gridsHollow cathodesHall thrustersIon and Hall thruster plumesFlight ion and Hall thrustersBased largely on research and development performed at the Jet Propulsion Laboratory JPL and complemented with scores of tables figures homework problems and references Fundamentals of Electric Propulsion Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry It also serves as an equally valuable resource for professional engineers already at work in the field.

A long time ago in a galaxy far, far away…. Star Wars is a movie produced by Lucas Films Ltd. If you are wondering why I have a slide dedicated to Star wars, I am a huge nerd and love it. That and it is relevant to the subject of Ion Thrusters. The next slide will explain. Hopefully. If you believed Star Wars was scientifically accurate in most regards, you may want to rethink the beliefs you hold about it. There is nothing else important being written here. Props if you kept reading it though. More props if you actually managed to read fast enough to make it to this point in this rather unimportant part of text.. Stephen Hevert. Affiliate Professor.
