Electric Propulsion Research & Development Activities


Elwing's Exclusive Electrodeless Electric Propulsion technology rationale :

Elwing was established to develop innovative electrodeless plasma propulsion technologies with a special emphasis on providing an edge over currently-available commercial electric propulsion technology such as Hall Effect Thrusters and Gridded Ion Thrusters.

Elwing's research & development team is focused on solutions to electric propulsion's worst short-coming : thruster reliability and lifetime.

One solution to these limitations is to take advantage of the ponderomotive force to produce a fully electrodeless plasma propulsion technology.
The fact that no electrodes are in contact with the plasma substantially reduces the erosion of the electrodeless thruster, which in turn extends the thruster's lifetime and reduces spacecraft contamination.
