The first ever ‘solid state’ plane with no moving parts in its propulsion system has successfully flown for a distance of 60 metres – proving that heavier-than-air flight is possible without jets or propellers.
The flight represents a breakthrough in ‘ionic wind’ technology – which uses a powerful electric field to generate charged nitrogen ions which are then expelled from the back of the aircraft – generating thrust.
Steven Barrett an aeronautics professor at MIT and the lead author of the study published in the journal Nature said the inspiration for the project came straight from the science fiction of his childhood.
‘I was a big fan of Star Trek, and at that point I thought that the future looked like it should be planes that fly silently with no moving parts – and maybe have a blue glow.
But certainly no propellers or turbines or anything like that.
So I started looking into what physics might make flight with no moving parts possible and came across a concept known as the ionic wind – which was first investigated in the 1920s.
‘This didn’t make much progress in that time.
It was looked at again in the 1950s and researchers concluded that it couldn’t work for aeroplanes.
But I started looking into this and went through a period of about five years – working with a series of graduate students to improve fundamental understanding of how you could reduce ionic winds efficiently and how that could be optimised’.
