<p>Propulsion apparatus consisting of a diverting duct (1) connected to a converging duct (2), with movable rear walls (4) to control the outlet area (9). When the apparatus is moved in the direction of arrow (5) in a body of fluid, the fluid is rammed into and enters the diverging duct from where fluid is directed into the converging duct and then exhausted and deflected past deflector (3). It is asserted that from this fluid flow, the forces formed by the static pressure of the fluid acting upon the walls of the apparatus, together with the forward momentum thereof, propels the apparatus.</p> |
