With the advent of the electric plasma jet engine, the future of air travel seems to be very bright.
what exactly is a plasma jet engine and how does it work?
Like the Pulsed Plasma Thrusters (PPTs) are high-specific-impulse, with low-power electric thrusters.
The proposed plans for how aircraft would use this technology are different: the new technology uses electricity and injected air to make the plasma.
The electric plasma engine concept is that electricity will convert directly into thrust by utilizing microwaves to generate energy from compressed air that turns into plasma propulsion.
Researchers in China from the Institute of Technological Sciences at Wuhan University have proposed a prototype device and published a research paper that explains the use of microwave air plasmas for jet propulsion.
The team used a plasma jet by compressing air and using a microwave to ionize the pressured air stream.
Another article published by the American Institute of Physics Advances also refers to a similar prototype design of a propulsion thruster that solely relies on air plasma induced by microwave ionization.
The prototype suggests that a jet engine uses only air and electricity to produce high temperatures for jet propulsion followed by a pressurized plasma at a specific setting.
During the observation, they noticed that given the same power consumption, its propulsion pressure is similar to that of a conventional airplane jet engine driven by fossil fuels.
The article also states that microwave power and airflow have a significant influence on plasma jet propulsion.
The device should utilize microwave air plasma for jet propulsion as a viable engine.
Therefore, with a combination of high-power microwave sources or an array of multiple microwave sources in parallel operation, it is possible to construct a high- microwave air plasma jet thruster using materials resistant to high temperature and pressure.
The challenge of scaling up plasma proportion technology for practical use in a jet engine is real.
With the plasma proportion technology, the power produced may not scale linearly, and comparing it to a conventional jet engine is just an uncertain idea and some grandiose claims.
Do you think this electric plasma jet engine can become the future of air travel by replacing the conventional jet engine?
Do you think it is possible to scale up the plasma jet engine?
