Spacecraft Electric Propulsion—An Overview
A short review of the status of electric propulsion (EP) is presented to serve as an introduction to the more specialized technical papers also appearing in this Special Issue (Journal of Propulsion and Power, Vol. 14, No. 5, Sept. –Oct. 1998). The principles of operation and the several types of thrusters that are either operational or in advanced development are discussed rst, followed by s...
متن کاملAssessment of High-Power Electric Multi-Mode Spacecraft Propulsion Concepts
Multi-mode spacecraft propulsion systems utilizing a chemical monopropellant or bipropellant thruster and high-power electric Hall, arcjet, or pulsed inductive thruster were analyzed and compared in terms of mission capabilities. These systems are most effective compared to an all-chemical system when greater than 25% of the total delta-V is accomplished by the electric system due to the high m...
متن کاملSpacecraft Propulsion Utilizing Ponderomotive Forces
A new spacecraft propulsion scheme is proposed which leverages advances in high-energy particle acceleration via laser-plasma interactions. Ponderomotive forces associated with laser wake-fields have demonstrated the potential to accelerate electrons to near-relativistic energies. Different schemes are investigated which may generate efficient propulsion systems for deep-space and manned space ...
متن کاملA Theory of Microwave Propulsion for Spacecraft
A new principle of electric propulsion for spacecraft is introduced, using microwave technology to achieve direct conversion of d.c. power to thrust without the need for propellant. A simplified illustrative description of the principles of operation is given, followed by the derivation, from first principles, of an equation for the thrust from such a device. The implications of the law of cons...
متن کاملElectric propulsion for satellites and spacecraft: established technologies and novel approaches
This contribution presents a short review of electric propulsion (EP) technologies for satellites and spacecraft. Electric thrusters, also termed ion or plasma thrusters, deliver a low thrust level compared to their chemical counterparts, but they offer significant advantages for in-space propulsion as energy is uncoupled to the propellant, therefore allowing for large energy densities. Althoug...
