MIT proof-of-concept demo of ionic wind propulsion for aircraft

Green Car Congress

MIT researchers have demonstrated that an aircraft with a 5-meter wingspan can sustain steady-level flight using ionic-wind propulsion. He expects that in the near-term, such ion wind propulsion systems could be used to fly less noisy drones. The MIT team’s final design resembles a large, lightweight glider. EAD airplane design.
