Abstract
U radu su određene odgovarajuće komponente propulzije i značajke brodskoga vijka za zadanu ribaricu kojoj je osnovna svrha prijevoz što veće količine ulovljene ribe. Objašnjena su dva karakteristična režima plovidbe i to su slobodna vožnja tijekom koje se dolazi do zadane pozicije za ribarenje i režim vuče pri kojemu se lovi riba po dnu mora pomoću mreže. Opisane su dvije vrste određivanja otpora broda prema Holtropu i prema van Oortmensenu. Opisane su i razlike u dvjema metodama te kako se razlikuju rezultati proračuna otpora za zadani ribarski brod. Napravljen je proračun za odabir optimalnog brodskoga vijka za zadanu ribaricu. Pri tom proračunu uzete su u obzir dvije vrste brodskoga vijka i to vijak s nepomičnim krilima (FPP – fixed pitch propeller) te vijak upravljivog uspona (CPP – controllable pitch propeller). Rezultati su se analizirali i izabran je vijak koji ima najveću iskoristivost za zadane režime rada te manju potrošnju goriva čime se automatski povećava mogućnost većeg ulova.
Abstract (english)
In this thesis the appropriate propulsion components and the characteristics of the ship`s propeller are determined. The main purpose of the fishing vessel is to transport as much fish as possible. Two characteristic modes of navigation have been explained and they consist in the free-riding mode, during which a given fishing position is reache, and a towing mode whereby fishing is done at the bottom of the sea by means of a net. Two methods of ship resistance are described, which are Holtrop and van Oortmensen methods. The differences between the two methods are also described and the differences in the results of the resistance calculation are analyzed for a given fishing vessel. A calculation was also made to select the optimal ship`s propeller for the default fishing vessel. In this calculation, two types of propellers are considered: the fixed pitch propeller (FPP) and the controllable pitch propeller (CPP). The results were analyzed and a propeller was selected as the one with the highest eficiency for the given operating modes and reduced fuel consumption, which automatically increases the possibility of a better performance.
