Abstract
A jet propulsion device and method for controlling movement of the jet propulsion device, where liquid inlets are positioned at a distance from the surface of the device. Preferably, the inlets are positioned in the stabilizing fins of the device. When the device reaches a certain speed, a Riabouchinsky cavity forms around the device, and the radius of the Riabouchinsky cavity is substantially equal to the distance between the inlets and the longitudinal axis of the device.
