Using Aluminum for Space Propulsion
Journal of Propulsion and Power, 2004The combination of aluminum and water was theoretically analyzed to assess its performance potential for space propulsion, in particular for microrocket applications and whenever a compact package is desirable. Heat of reaction, impulse density, and handling safety are features making this combination interesting for chemical thrusters, especially ...

Electro-chemical propulsion for space exploration
53rd AIAA Aerospace Sciences Meeting, 2015This paper wants to explore the feasibility and convenience to couple an electromagnetic with a chemical thruster in order to exploit the modest propellant consumption of the first and the high thrust of the second. Coupling the advantages of electric propulsion and chemical allows an electric thruster to perform manoeuvers where higher thrust is ...

Space electric propulsion plasmas
IEEE Transactions on Plasma Science, 1991Electric thrusters offer the promise of a substantial improvement in performance over that of conventional chemical rockets currently used in space propulsion applications. There are three basically different ways in which electrical power and propellant inputs might be combined to produce thrust: (1) propellant can be heated electrically and then ...

Electrical Engineering, 1960
General characteristics of electric propulsion systems for space vehicles, the energy sources and conversion efficiencies available, projected powerplant weights, and some of the various schemes for generating the ion and plasma jets. Also included are results of experimental units and their feasible range of application.

AIAA International Air and Space Symposium and Exposition: The Next 100 Years, 2003
Abstract : As the world of flight enters its second century, in-space propulsion nears the end of its first 50 years. The field is progressing rapidly, with a diversification of propulsion technologies that enable space missions that were previously untenable.

Space Programs and Technologies Conference, 1992
A development status-and-prospects evaluation is presented for the range of spacecraft propulsion alternatives under consideration by the USAF's Phillips Laboratory, encompassing technologies broadly characterizable as 'conventional' (solid, storable liquid, cryogenic) and 'nonconventional'.
