HYDROKOPTERHYDROCOPTER
Die Entwicklung schneller Boote verlief über den Gleiter, Tragflächenboot zum Luftkissenboot.The development of fast boats went through the glider, Hydrofoil to hovercraft.
Stets war dabei das Streben maßgebend, das Boot aus· dem saugenden Element des Wassers weitestgehend herauszuheben, um die Verschiebung der Wasserverdrängung zu beseitigen. Die Fortschritte, die das Tragflächenboot über den Gleiter hinaus erreichte, reichen aber nicht aus, da die Tragflächen als Bremswirkung in der Größenordnung des Bootsgewichtes wirken.The aim was always to get the boat out of the to lift out the sucking element of the water as far as possible in order to eliminate the displacement of the water displacement. However, the advances the hydrofoil made beyond the glider are not enough, as the hydrofoils as a braking effect in the order of magnitude of the weight of the boat works.
Im Vorliegenden wird nunmehr so vorgegangen, daß der Bootskörper direkt durch den Antrieb selbst aus dem Wasser gehoben
wird analog dem Helikopter, wo durch Luftunwälzung des
Antriebs die Last gehoben wird.
Das Kräfteparallelogramm macht den Vorgang deutlich.In the present case, the procedure is that the hull is lifted directly out of the water by the drive itself, analogous to the helicopter, where the load is lifted by air circulation of the drive.
The parallelogram of forces makes the process clear.
Helikopter: Abb. 1Helicopter: Fig. 1
Wenn die Kraft K gleich ist der Größe der Last L, so steht die Last frei in der Luft. Wird die Kraft K größer als L, so hebt sich die Last. Wird die Kraftrichtung geneigt, so sich die Last in der Horizontalen.If the force K is equal to the size of the load L, the load is free in the air. If the force K is greater than L, so the burden is lifted. If the direction of force is inclined, the load becomes horizontal.
Hydrokopter: Abb. 2Hydrocopter: Fig. 2
Wird die Kraft K gleich der Last L, so befindet sich der J Körper in der Schwerelosigkeit und kann deshalb frei in die Luft über das Wasser gehoben werden durch geringe Steigerung von K. Wird die Kraftrichtung geändert, so muß K größer werden und gesteigert bei größtmöglicher Neigung (s. Abb. 3). · '"--■■'If the force K becomes equal to the load L, the J body is in weightlessness and can therefore be lifted freely into the air over the water by slightly increasing K. If the direction of force is changed, K must be larger and increased at the greatest possible Inclination (see Fig. 3). · '"- ■■'
Wird K geringer als in Abb. 3 gemäß Abb. 4, so stürzt das Boot zurück aufs Wasser.If K becomes less than in Fig. 3 according to Fig. 4, it falls Boat back on the water.
Wird K wesentlich übersteigert über den Grad bei Abb.- 3 hinaus, so entsteht die Tendenz, die Schrauben an die Wasseroberfläche zu treiben (s. Abb. 5).If K is significantly exaggerated beyond the degree in Fig. 3 In addition, there is a tendency for the screws to hit the surface of the water to drive (see Fig. 5).
