Power-Conditioning Requirements for Ion Rockets

Data are presented that are important in the design of electrically propelled spacecraft. An explanation is given for what has been done with regard to the power-conditioning equipment for small ion rockets up to 3 kw including the problems encountered. The expected power distribution of 30-kw electron-bombardment and contact-ionization rockets is presented, although engines of this size have not been tested. The electrical power requirements are presented in a form compatible with system studies.
