This paper investigates a novel jet-propulsion method for a submerged vehicle. The approach is based on flexible-tube, eccentric rotor, Downingtown-Huber type pumps. Equations of motion are derived for a craft driven by such pumps. In order to develop general insight into the overall dynamics of the system, simulations are carried out for the simple case of horizontal straight-line motion. Results are obtained for the vehicle velocity, distance traveled, pump speed, and energy consumption. Effect of drag forces on the operation of the craft is studied. Finally, the jet-propulsion system is compared with conventional screw-type propulsors via simulation.
