- 15 - Potential increase in performance of existing space propulsion systems – Electric Propulsion Most promising for further increase of propulsive performance capabilities is the use of electric propulsion. This technology, although still under development, has proven to achieve thruster exhaust velocities ve an order of magnitude higher than the best performing chemical thrust engines. Although electric propulsion leads to substantial propellant mass savings compared with chemical propulsion, considerable power consumption will require increased mass of power supply systems. Therefore, for electric propulsion, the determination of the systemspecific impulse, Issp, requires also the consideration of contained mass of the power supply/power processing systems and thruster, mEl. Here high performance is not dictated by maximum but rather by optimum values of thruster exhaust velocity, ve-opt. For electric propulsion, high values of Issp will be achieved mainly for high values of ve-opt. which requires particularly high values of overall specific power γ, overall power conversion efficiency η and thrust operation time τ . From parametric investigations it is obvious, that for deep space missions mainly power supply systems with high specific power γ need to be further developed to achieve high values of Issp. For high optimum thruster exhaust velocity, ve-opt, e.g. Field Emission Electric Propulsion (FEEP) will have to be used.
