Description

vanessa-0 Uppfinningen beskrives mer 1 detalj med hänvisning till den bifogade rit- ningen, på vilken figur l är en ändvy av en propeller enligt föreliggande uppfinning, sedd mot den ihåliga axelns fria ände; figur 2 är en sidvy av den propeller, som visas i Eig. l och fig. 3 är en vy av ett snitt längs linjen III ~ III 1 fig. l och 2.
Tre skruvblad 2, 3 och 4 är anbragta på en ihålig axel 1 medelst svetsning.
I det nedre området delar sig alla tre skruvbladen 2, 3, 4 i nedåt diver- gerande bladdelar 5, 6, vilka bildar en kammare 4. Kammaren 4 är förbunden I med den ihåliga axelns l inre via en förbindelsekanal 7. Kammarens 4 tvär- snitt är V-format, varvid spetsen 8 pekar utåtf Utträdesöppningen 10 i varje kammare 4 begränsas av en övre resp. nedre kant 9, ll, vilka kanter korsar varandra, sedda i den ihåliga axelns 1 axiella riktning, varvid den nedre kanten 11 sträcker sig förbi den övre kanten i den yttre zonen. Eftersom bladets periferihastighet är störst i zonen för spetsen 8, och utträdesöpp- ningens minsta tvärsnitt förefinns här, bringas den luft, som suges från den ihåliga axeln l att utträde i spetsens 8 zon med särskilt hög hastighet.
