Do plasma engines work in space?
So, plasma-based propulsion methods such as ion thrusters have shown practical (though limited) use in space, where there is no gravity and no air resistance to overcome, and cumulative (if small) amounts of thrust can produce significant velocity over time. A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma.Therefore, these engines dump most of the energy they produce into the exhaust, and very little into the thing they are propelling. Even if aliens gave you a small, light plasma thruster that ran directly on jet fuel, it would still be unusable for an airplane just because of that high exhaust velocity.
Has Russia built a plasma engine?
Russia has developed a new nuclear-powered plasma engine that could cut travel time to mars down to just 30–60 days. Unlike traditional propulsion systems, this advanced engine uses a magnetic plasma accelerator to propel charged particles at speeds up to 100 km/s. Russian scientists at rosatom have developed a laboratory prototype of a plasma electric rocket engine that could potentially reduce travel time to mars to between 30 and 60 days. This engine utilizes a magnetic plasma accelerator, differing from traditional chemical rocket engines that rely on fuel combustion.Russia has unveiled a prototype plasma engine designed to dramatically reduce interplanetary travel time. Unlike traditional chemical rockets, this engine uses superheated plasma and electromagnetic fields to generate continuous thrust with higher efficiency.
