Abstract

Pogonski sustav broda koji obuhvaća najmanje jedan brodski vijak, koji je postavljen na osovinu brodskog vijka (PA), jedan uređaj (10) za smanjenje snage potrebne za pogon broda, koji je čvrsto montiran na tijelo broda ispred brodskog vijka u smjeru kretanja broda, i jednu pred-mlaznicu (20), pri čemu navedena pred-mlaznica (20) ima unutarnji promjer koji je manji od 90 % promjera brodskog vijka, i pri čemu je pred-mlaznica (20) postavljena tako da je rotacijski simetrična s obzirom na svoju os (21) koja je postavljena tako da je pomaknuta u smjeru prema gore iznad osovine brodskog vijka (PA), naznačen time što su unutar pred-mlaznice postavljene peraje odnosno nosiva krila (30, 30a, 30b, 30c, 30d), pri čemu su peraje odnosno nosiva krila (30, 30a, 30b, 30c, 30d) postavljene nesimetrično u unutarnjem prostoru (20a) pred- mlaznice (20), a postavljene su radijalno u odnosu na osovinu brodskog vijka (PA). Patent sadrži još 7 patentnih zahtjeva.

Claims (8)
