A thrust-producing device comprises a body having a surface and a periphery and disposed in a first fluid; a generator for imparting energy to a second fluid; and a distributor connected to the generator, disposed adjacent the surface, for distributing the second fluid in a first stream over and adjacent the surface for blanketing and enclosing at least a portion of the surface with the first stream and causing the first stream to be initially sufficiently unattached to the surface to define a closed volume between the surface and the first stream. The distributor imparts sufficient velocity to the first stream for permitting a substantial portion of the first stream to reach beyond at least a portion of the body periphery and to partially evacuate by entrainment the volume and to create a low pressure within the volume relative to a pressure of the first fluid and to generate a second stream within the volume; whereby at least a substantial portion of the first stream is deflected angularly and around at least a portion of the body by the dynamic interaction of the first stream with the first fluid and the second stream and the low pressure within the closed volume, and whereby the at least a substantial portion of the first stream entrains a portion of the first fluid to produce a combined resultant fluid flow which proceeds angularly and around at least a portion of the body, thereby creating a resultant thrust force acting on the body. A method for producing thrust for a body is also disclosed.
