摘要：This application concerns a method and system using a hydrodynamical effectfor producing a potential over a body. The force obtained this way is useful for thepropulsion and manoeuvering of ships, submarines, aeroplanes, and airships. A body

immersed in a fluid at rest is subject to equal pressures on all sides. A stream close toone side of the body will reduce the local pressure and produce a potential over thebody. This is currently done by moving the body in the fluid, cf. aeroplane wings. Thepotential may be produced by setting up a stream or streams over one side of the body.Bodies attached to aeroplanes by hinges are useful for their lift, propulsion andmanoeuvering, and will make them independent of velocity for lift and manoeuvering.The same will be the case for submarines. Airships and seagoing vessels may be designedso as to have their propulsive bodies integrated in their form. The streams are producedfrom nozzles, holes, or slits in tubes placed near the stagnation line of each body, thusdefining its leading edge. Used on a ship, this technique lowers its bow wave and removesthe dynamical losses connected with screw propulsion. The manoeuvering force andprecision are enhanced.
