VORTEX PROPULSION UNITS OF SEA VESSELS AND AIRCRAFTS

Abstract

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT Basic diagrams and estimates of the main parameters of sea vessels and aircrafts with propulsion units in the form of generators of vortex pairs, including toroidal vortices (thermals) are proposed. It is shown that the efficiency of such propulsion units increases with the increase in their dimensions, so that in case of surface vessels propulsion units provide the buoyancy of the vehicle, the ability to locate a useful volume in the above-water part, and in case of air and submarine vessels - inside the propulsion unit. Since the vortex pair moves in the environment, without experiencing frontal resistance, vessels, manufactured according to the proposed schemes, also do not have frontal resistance. This factor gives the design a considerable advantage in the cost of power to move through water and air. Keywords: aircraft, sea vessels, vortex pair, drag, dissipation of vortex energy, structural features.
