ABSTRACT:
The throat configuration of a converging-diverging nozzle (16) is varied by defining a throat area (18) of the nozzle by a plurality of impinging ion beams arranged symmetrically around the throat area of the nozzle and directed toward a central point (34) within the aforementioned throat area. Each of the ion streams is independently controlled so as to permit variation in the symmetry of the throat area as well as the size thereof, and permit deflections of the fluid flow paths as well as changes in, for example, a thrust generated by a fluid stream passing through the nozzle.
