Abstract
Anordning, f.eks. et båtskrog og et fremdriftssystem til frembringelse av relativ bevegelse av en flytbar substans, f.eks. vann. En kanal som har en åpen oppstrømende og nedstrømende danner i det minste delvis en strømningsbane. Kanalen Innbefatter et kjernepartl som er helt lukket i tverretningen i avstand fra oppstrømenden, med en fluidumbevegende rotor 30 som er dreibart opplagret i kanalen og et overgangsparti som strekker seg forover fra oppstrømenden av kjjerne- partiet. Kanalutformningen og rotoren 30 er innrettet til å muliggjøre en kontinuerlig reduksjon av tverr- snittet for strømningsbanen på nedstrømssiden langs overgangspartiet. Hvis anordningen er et båtskrog er baugen 12 utformet for å skape gassmøring av skroget ved samvirkning med vannet under bevegelse. Overgangs- partiene for kanalene kan ha åpne bunner og ribber 26 er anordnet for å omgi drivaksler 42 som strekker seg ned til rotorene 30. Baugen 12 gir et løft og ned- advendte flater 26 nær akterenden er skråttstilt for å balansere dette løft slik at båten kan stige på vannet med en nærmest parallellforskyvningsbevegelse.Selve rotorene 30 er også forbedret.Device, e.g. a boat hull and propulsion system for producing relative movement of a flowable substance, e.g. water. A channel having an open upstream and downstream at least partially forms a flow path. The channel includes a core portion which is completely closed in the transverse distance from the upstream end, with a fluid-moving rotor 30 rotatably supported in the channel and a transition portion extending forwardly from the upstream end of the core portion. The duct configuration and rotor 30 are arranged to enable a continuous reduction of the cross-section of the downstream flow path along the transition portion. If the device is a boat hull, the bow 12 is designed to create gas lubrication of the hull by interacting with the moving water. The transition portions of the channels may have open bottoms and ribs 26 are arranged to surround drive shafts 42 extending down to the rotors 30. The bow 12 provides a lift and downwardly facing surfaces 26 near the stern are inclined to balance this lift so that the boat can rise on the water with a near-parallel displacement movement. The self-rotors 30 are also improved.
