Air Plasma Engine That Works Without Fossil Fuels
most of scientists Design a Prototype 'Air Plasma' Engine That Works
Without Fossil Fuels
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.
- the New Jet engine promises to fly passengers halfway around the world — without burning fossil fuels.
- The engine developed at the Institute of Technological Sciences at Wuhan University would allow passengers to fly carbon-neutral skies. Researchers say it needs only electricity and the air that swirls around it.
- The new device compresses air into high pressures to become ionized plasma.
- The researchers created thrust pressure comparable to a commercial jet engine.
the Plasma engines have a much higher specific impulse (Isp)
value than most other types of rocket technology. The VASIMR thruster can be
throttled for an impulse greater than 12000 s, and hall thrusters have attained
about 2000 s.
Disadvantage
While in operation the plasma can thermally ablate the walls
of the thruster cavity and support structure, which can eventually lead to
system failure. Design and materials advancement may solve this problem. Due to
their extremely low thrust, plasma engines are not suitable for launch-to-orbit
on Earth.
