It is a definition engineers use to quantify the effectiveness of propellant use in a propulsion system. In physical terms is the amount of impulse the engine produces divided by the weight of the propellant required to create that impulse.

Learn what happens when electrical power adds energy to propellant in a propulsion system in the latest episode of Aerojet Rocketdyne's "What Is?" series.

Within an electric propulsion system the core component of the electric machine4 can improve, extend, or even replace the combustion engine as a propulsion source. For example, in the concepts of the range-extender vehicle, the battery electric vehicle (BEV), or the fuel cell vehicle, the electric motor is defined as the single propulsion source.

Electric propulsion is a type of locomotion using electric motors to move a vehicle. This type of propulsion is often used as an alternative to internal combustion engines, such as gasoline or diesel motors.

The Battery Protection function of the VETUS electric propulsion motor also ensures that the battery pack is not unnecessarily damaged, and the service life cycle of the batteries is guarded for the present and future boating seasons. Discharging a battery pack below the specified minimal voltage will damage the batteries and reduce the life span.

How does an electric propulsion system work on a spacecraft?

  • A complicated electromagnetic process happens inside the thruster with fuel that’s on board (typically Xenon in current systems) to create ions, which are sped up through a electric field to create an exhaust plume. As with chemical systems, this exhaust plume is what pushes the spacecraft in the direction it needs to go.

How does nuclear electric propulsion works?

NTP systems work by pumping a liquid propellant, most likely hydrogen, through a reactor core. Uranium atoms split apart inside the core and release heat through fission . This physical process heats up the propellant and converts it to a gas, which is expanded through a nozzle to produce thrust.

How does solar electric propulsion work?

  • Solar electric propulsion takes advantage of magnetism and electricity to push a ship through space. Electricity, generated by the ship's solar panels, gives a positive electrical charge to atoms inside the chamber. They are pulled by magnetism towards the back of the ship and then pushed by magnetic repulsion out of the ship.
