Аннотация:There are different technologies of formation the artificial sources of non-uniformity. The SOE technologies are convenient in many aspects, but they are not the most advantageous from the point of view of the supplied power. In this paper it is shown that the dynamic method (DIZ) may be more profitable. In the Table the result (8) concerning the possible relative power decreasing (W1–W2)/W1 (in percents) due to transition from energetic to dynamic non-uniformity
formation method is presented. The keeping in the flow ahead of a body the leading solid obstacle may be realized by different ways: mechanical contacting (e.g. an aerodynamic solid string or spike) or MGDtechnologies. In the latter case it is possible to keep a compact set of the small magnetic particles or an ionized gas bunch by the electromagnetic field. Also it may be interesting to use the combined technologies, i.e. SOE and DIZ simultaneously.
