Who glide through the skies and don’t want to crash, needs a boost. These provide either large gas-filled body like a hot-air balloon or Zeppelin, or suitably shaped wings that are fast enough flow of air, such as in a plane, a helicopter or a drone. Now connect the soundless Floating rather with balloons, while the nozzle works, propellers and rotors of other machines for significant noise emissions from engines. All of these engines share a basic property: they convert the chemical energy of a fuel or a battery into rotational energy, speed up about rotary-wing the ambient air for propulsion.
but You could also make it in a very different, quiet way, the necessary Wind: by the end of the nineteenth century, researchers have thought about the speed of the ions, one could produce with the help of the then newly discovered x-rays in air. It costs a certain amount of energy to ionize air particles by wresting them one or more electrons and makes them positively charged particles. But this is done only once, in an electric field to accelerate. Researchers at the Massachusetts Institute of Technology have taken up this idea and built the first aircraft, the only electrically charged wires as the “engine” uses. In the Journal “Nature” describe you, that your apparatus has no moving parts, only a battery and a high voltage system. Their lightweight design weighs less than 2.5 kilograms with a wingspan of five meters.
fly with high voltage
In the atmosphere, ions are separated, resulting, among other things, by cosmic rays and natural background radioactivity. It is much to a few but to a significant air flow induce. The scientists used, therefore, discharge reactions, to produce a measurable ion wind. Under the wings they spanned several layers of high-tension wires, where they put on the front, small wires 20 kV positive voltage, while the wider rear collector electrodes with 20 kilovolts were negatively charged.
