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 ...

Is laser space propulsion practical?: review
Applied Optics, 2021In this paper, we review practical limitations to laser space propulsion that have been discussed in the literature. These are as follows: (1) thermal coupling to the propelled payload, which might melt it; (2) a decrease in mechanical coupling with number of pulses, which has been observed in some cases; and (3) destruction of ...

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.

Abstract The past and the recent status of nuclear propulsion (NP) for application to space mission is presented. The case for using NP in manned space missions is made based on fundamental physics and on the necessity to ensure safe radiation doses to future astronauts.

Propulsion for the space station
Acta Astronautica, 1987Abstract Propulsion for the Space Station requires a unique, challenging combination of features. The propulsion requirements demand responsive capabilities for orbit control and countering on-board or externally induced forces, and precision control for station-keeping with minimum disturbances. The propulsion design must provide high performance to

Electronics and Power, 1968
In the past 20 years, electrical methods of propelling space vehicles have developed from the speculative stage to practical reality. While it is inconceivable that electric thrustors could be used as rocket launchers, once in orbit electric propulsion is particularly suited to missions where a source of electric power is also required for some other ...

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'.

IRE Transactions on Military Electronics, 1959
The possible role of a controlled thermonuclear reactor in space missions is discussed. Although such a reactor is many years from reality, some of its properties are understood well enough to indicate problems which will appear and which are peculiar to space flight. It appears that it will have to deliver electric power or thrust at a weight of about

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 ...

Plasma Physics and Controlled Fusion, 2011
Plasma thrusters are challenging the monopoly of chemical thrusters in space propulsion. The specific energy that can be deposited into a plasma beam is orders of magnitude larger than the specific chemical energy of known fuels. Plasma thrusters constitute a vast family of devices ranging from already commercial thrusters to incipient laboratory ...
