High energy long living non equilibrium plasmoids in a gas flow and atmosphere

Summary form only given. High energy long living structural non equilibrium plasma formation (further named plasmoids, P) were created by means of pulse plasma gun (erosive discharge), HF and microwave discharge generators. Very complex filamentary structure of these plasma objects was discovered. The following anomalous properties of these objects were revealed in flow and in atmosphere: high non-equilibrium level of plasma (Ne>1015 cm/sup 3/, Te-1 eV/spl Gt/Tg/spl sim/1000 K); high sound velocity inside P, Vs/spl sim/2000 mps; surface tension; super penetration of the P through supersonic flow; selective interaction of the P with metals and dielectrics; penetration of the P through narrow channels; distraction of these objects by additional heating, and others. Specific plasma energy of these objects could reach up to 10-100 eV/atom. There were revealed two different types of decay of these objects: with explosion and without explosion. We used these plasmoids for drag reduction of body in supersonic flow.
