Proceedings of the Institution of Electrical Engineers, 1964
Electric drive is not advocated for all vessels, as its adoption can involve additional weight, complexity and cost. It can be justified where flexibility of machinery layout and operation, rapid manoeuvrability, constant-power characteristics and simple provision of power for large auxiliaries are features which can be utilised in service.

As we have seen in previous chapters, chemical propulsion systems are limited in performance by the energy stored in their propellants. This limitation can be overcome by using electric power available on the spacecraft (e.g., from solar arrays, nuclear reactors or beamed energy sources such as laser light or microwave energy transmitted to the ...

Electric Propulsion Development
The Aeronautical Journal, 1969In Part I of this series of papers, the development was described of a kW ion thruster for use as one of a set of primary propulsion units to be used for executing an orbit transfer manoeuvre. Both during the expansion phase, and when the final orbit is attained, micro-thrusters are necessary to provide attitude and position control of the satellite ...

The propulsion of ships by electricity
Journal of the Institution of Electrical Engineers, 1928After a short introduction to the subject proper the conditions of service, i.e. the loading of generators, is reviewed, and this is followed by a few notes on the control of electrically propelled ships. A short description of the types of motors used is given, and this is accompanied by a mention of a few of the more interesting points in the ...
