Abstract

A találmány tárgya nagy teljesítményű légcsavar, amelynek van egy agya(2) és több lapátja (3), amire jellemző, hogy mindegyik lapátlapátcsúcsa egy-egy kétoldalas vagy egyoldalas íves peremmel (1) vanellátva. A találmány szerinti hajtócsavar kis indukált ellenállást tudbiztosítani, és a centrifugális erőt effektív erővé tudja átalakítani,növelve a lapátcsúcsok közelében a nyomáskülönbséget, és növelveezáltal a lapátokra ható erőt. A vizsgálatok szerint oldalirányúdőléssel rendelkező típusú nagy hajtócsavar ugyanolyanteljesítményfogyasztás mellett az áramlás nagyságának mintegy 12-17%-os növekedését mutatja, ami 40-70%-os energiamegtakarítássalekvivalens. Mivel a közeg dinamikus viselkedése végtelenhez közelítőoldalarányt mutat, a lapátok szélességét növelni lehet, miközben azindukált ellenállás nem növekszik. A lapátterületet növelése és aközegkiáramlási sebesség csökkentése módszerét alkalmazva azenergiamegtakarítási hatás jelentősen növelhető még a találmányalapján. Ó
