ABSTRACT:
A drive for submerged portions of floating bodies, i.e. watercraft comprising a pulsating nozzle including a control device for pulsating the nozzle by expansion and contraction of an open inner nozzle diameter portion. The control device contracts and expands the nozzle such that during expansion the front of the nozzle is expanded to a greater extent than the rear of the nozzle to produce a positive angle of attack, and during contraction the rear of the nozzle remains expanded to a greater extent than the front of the nozzle to produce a negative angle of attack.
