Verfahren zum Antrieb von Wasser-und Luftfahrzeugen.
Der hauptsächlichste Fehler der meist angewandten Triebsysteme zur Fortbewegung von Wasser-und Luftfahrzeugen (Schraube und Schaufelrad) besteht offenbar darin, dass die von ihnen erzeugten Über- und Unterdruckgebiete räumlich zu nahe beieinanderliegen, daher beim Ausgleich nur ein ganz kurzer Weg vorhanden ist. Diese Systeme nutzen auch

Es sind nun Versuche gemacht worden, ein Unterdruckgebiet vor das Schiff und ein Überdruckgebiet hinter dasselbe zu verlegen, so dass die ganze Länge des Schiffes als

In dem Schiffskörper a befindet sich eine Turbien b mit Leitschaufelkranz vor und hinter dem Laufrad. Vom Bug des Schiffes aus geht eine hinten verjüngte Saugleitung c xur Turbicc. Die-Saugleitung ist so gestaltet, dass hie sich an der Spitze gabelt und zwei

Die absolute Geschwindigkeit des austretenden Wassers würde darnach gleich Null soin.
Diese Art des Antriebes ist natürlich nicht nur für sich im Wasser bewegende Schiffe, sondern auch für Luftschiffe anwendbar, indem die Luft in derselben Weise, wie

Method for propulsion of watercraft and aircraft.
The main fault of the propulsion systems most commonly used to move watercraft and aircraft (propeller and paddle wheel) is apparently that the overpressure and underpressure areas they create are too close to each other, so there is only a very short distance to compensate. These systems also use
EMI1.1
Attempts have now been made to move a negative pressure area in front of the ship and an overpressure area behind it, so that the entire length of the ship as

Part of the work is lost in the form of kinetic energy in the freely escaping water jet.
EMI1.3
In the hull a there is a turbine b with a guide vane ring in front of and behind the impeller. From the bow of the ship a suction line tapered at the rear goes c xur Turbicc. The suction line is designed so that it forks at the top and two

speed into the outflow line g, within which the kinetic energy of the water is converted into hydraulic pressure due to the gradual widening of the cross-section, in such a way that the relative exit speed at the rear is equal to the speed of the vehicle. The absolute speed of the exiting water would then be zero.
This type of propulsion is of course not only applicable for ships moving in water, but also for airships, by moving the air in the same way as
