MIT engineers created an airplane that can fly without the use of moving parts. This was achieved through the use of electro-aerodynamic propulsion. The pair of electrodes used in it pushes ions, creating an ionic wind flow. Scientists have known about this phenomenon for half a century. Even at Apple, years ago, they wanted to cool their laptops with it. However, for the movement of an aircraft it is used for the first time. True, while we are talking only about a drone weighing 2.45 kilograms. If the engineers achieve an increase in the size of the model to the parameters of a real aircraft, it will have a lot of advantages. The new vehicle will be much quieter, safer, greener and easier to maintain. But to achieve this is not easy. To supply the required 40 thousand volts, you need a large, heavy battery. Compensate for these shortcomings due to the design. According to engineers, so far the technology can be used to power small flying unmanned aerial vehicles. It is also applicable in combination with conventional aircraft engines, then the aircraft will become more economical.
