Plans that travel with moving areas are now realistic.
When you're in the Star Trek you've seen them.
When he was a kid, MIT's associate professor Aeronautics and astronomer Steven Barratt saw them. Now he developed the wind-powered plane of the ion of his childhood dreams.
It flew an airplane without any moving parts.
"Long-term future flights do not have any props and turbines," says Barrack. "They should be more like the ships in the trak track, it's just a blue glow and a silly glide."
The lines that stand in front of the model are electrified.
The "Ionic wind" is known as the "electro-hydroelectric energy". In fact, it is based on a principle that was originally identified in the 1920s.
It describes a thickness or temperature, which produces when a power between thin and thick electrodes passes. If sufficient voltage is applied, the air on the electrodes can generate enough energy to handle a small plane.
But in practice, its reality is not progressing beyond the hobbyier, which raises little models.
Nine years ago, a space bomber went to work on the back of a cover of a cab on a sleepy night in a hotel.
Recently, they traveled 60 mm apart from a 5 meter mound in the gymnasium at MIT's duPont athletic center.
The plane repeated 10 times. Each time, the aircraft repeatedly gave enough power to sustain the same distance.
"It was possible to design a simple platform that could prove an idea of an airplane fly," Burrett said.
"A little more than a plane that can handle a useful mission has become a bit longer, and it must be more efficient, no more can fly, fly out."
How does Ionus work?
This energy is fuelsle with lithium-polymer batteries.
But the key to constructing it is from the members of the Electronics Research Laboratory of Prof. David Perl's power electronics research group
They designed a power supply that transformed the batteries, so they would supply power to provide 40,000 volts.
The technical explanation of what is happening here is through MIT News:
When the wire is vibrating, they work to attract and remove negative charging electrons from the air molecules around them, giant winds, as well as attraction of the iron edge. The rear air molecules are newly ionized and therefore attracted to the negligible charged electrode in the rear of the plane.
Since the newly formed clouds of ion negative charge flow into the wires, each IO can be combined with other air pollutants for millions of times.
We've seen iON drives earlier. NASA has a system called HiPEP, a student at Sydney University student Patrick "Pad" uses a system that allows long-range travels through Newman space.
But none of them will have to fight against gravity.
Barat's team is now trying to improve the efficiency of their design, to create more loose winds with more voltage.
"It took a long time to get here," says Barrack. "Going from the basic principle to the flying birds was a long-distance journey of the symbolism of physics, and then proceeded with the design.
"Now the possibilities for this type of propulsion system will take effect."
