Electric Propulsion (EP) is a class of space propulsion which makes use of electrical power to accelerate a propellant by different possible electrical and/or magnetic means. The use of electrical power enhances the propulsive performances of the EP thrusters compared with conventional chemical thrusters.

This is confirmed by the fact that the Fédération Internationale de l’Automobile (FIA) has established a recognised technical formula for sanctioned competitive electric kart racing. Electric kart racing was introduced into Europe in with a set of technical regulations that are quite open at this early stage.
This research considers the design and sizing process of a hybrid-electric propulsion system for a single-seat demonstrator aircraft, the experimental derivation of the internal combustion engine map, and the electric motor parameters.

To accommodate these often contradictory targets, electrified aircraft propulsion is seen as a promising area. This section discusses, based on the work done in , how simulation is used to assess CO 2 and NO x emissions of a parallel rotorcraft hybrid electric propulsion system.
The benefits of running simulations are two-fold. In electric propulsion systems, the energy is imparted to the propellant via essentially three methods: 1) Electrothermal, which involves heating the as resistively via the passage of current through it or the interaction of a gas with a hot element 2) Electrostatic, where the gas is ionized and accelerated via applied electric fields 3.

A FEEP device consists of an emitter and an accelerator electrode. A potential difference of the order of 10 kV is applied between the two, which generates a strong electric field at.Electric propulsion. Electric propulsion systems use an external source such as a nuclear reactor or solar cells to generate electricity, which is then used to accelerate a chemically inert propellant to speeds far higher than achieved in a chemical rocket.
Such drives produce feeble thrust, and are therefore unsuitable for quick maneuvers or.
