DBD plasma actuators employed for airflow control applications (Adapted with permission from [1]). Plasma actuators are a type of actuator currently being developed for active aerodynamic flow control. Plasma actuators impart force in a similar way to ionocraft. Plasma flow control has drawn considerable attention and been used in boundary ...
The Wingless Electromagnetic Air Vehicle (WEAV) is a heavier-than-air flight system which can self-lift, hover, and fly reliably with no moving components. The Wingless Electromagnetic Air Vehicle (WEAV) is a heavier than air flight system developed at the University of Florida, funded by the Air Force Office of Scientific Research.
Due to the thin air at higher altitudes, a much higher true airspeed (TAS) is required to generate sufficient lift on the wings. The absolute ceiling is therefore the altitude at which the engines are operating at maximum thrust, yet can only generate enough lift to match the weight of the aircraft. Hence, the aircraft will not have any excess ...
A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/ anodes .

This would be sufficient to power a MPD upper stage, perhaps to lift satellites from LEO to GEO. [11] Another problem with MPD technology has been the degradation of cathodes due to evaporation driven by high current densities (in excess of 100 A/cm 2). The use of lithium and barium propellant mixtures and multi-channel hollow cathodes has been ...
By 2021 development of a 300 mN thruster was complete. Alongside it, RF-powered 10 kW plasma engines and krypton based low power electric propulsion were being pursued. [16] [better source needed] With private firms entering the space domain, Bellatrix Aerospace became the first commercial firm to bring out commercial Hall-effect thrusters.
