Air Plasma Engine That Works Without Fossil Fuels

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 high-temperature plasma is created using only injected air and electricity.
  • The new device compresses air into high pressures to become ionized plasma.
  • The researchers created thrust pressure comparable to a commercial jet engine.
  •  Advantages
  • 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.
