It isn't excluded that in the near future there will be first light planes on almost silent and environmentally friendly jet draft.
Researchers from Massachusetts Institute of Technology (MIT) carried out a series of calculations and experiments and found out that atmospheric ionic engines can be much more effective, than was considered earlier.
Actually the phenomenon of electrohydrodynamic draft or simply an ionic wind was open in 1960. Its essence in the following: when current passes between two electrodes one of which is thinner, than another, the air stream is created. If a tax on conductors sufficient tension, it is possible to receive very powerful air stream which will be to hold the plane in air enough.
Unfortunately this, undoubtedly, attractive type of the jet engine long time remained an entertainment for engineers and conjurers as was considered insufficiently powerful a share of creation of "serious" jet draft. Some scientists assumed that atmospheric ionic jet engines are extremely inefficient: demand a huge number of the electric power at not so big draft.
Nevertheless, calculations and experiments of experts of MIT showed that in certain conditions ionic engines can be much more effective source of draft, than ordinary jet engines. In the experiments they found out that the ionic wind can give out to 110 newtons of draft on kilowatt, in comparison with 2 newtons on kilowatt at the ordinary jet engine. Thus the ionic wind effectively to be used on some types of aircraft, first of all on small light planes. Thus ionic engines are almost silent and invisible in the infrared range as don't allocate huge quantity of heat as the traditional jet.
In MIT developed basic design of the effective ionic engine. Installation for production of an ionic wind consists of three parts: very thin copper electrode (issuer), thick tube from aluminum (collector) and an air g
