Abstract
Śmigło składające się z piasty oraz co najmniej dwóch połączonych z nią łopat o zmiennym profilu od nasady po końcówkę, charakteryzuje się tym, że piasta (2) posiada wlot (2a) i przedni otwór a łopaty (1) posiadają wydrążony kanał wewnętrzny, ponadto piasta (2) wyposażona jest w otwór piasty (2) a łopata (1) posiada wlot korespondujący z otworem piasty (2) oraz wylot w postaci szczeliny, przy czym kanał wewnętrzny w nasadzie ma kształt kołowy, w ok. 25% rozpiętości przechodzi w przekrój profilu, tworząc profil cienkościenny aż do końca łopaty (1).
