Geometry creation of water turbine spiral casing

Završni rad prikazuje način na koji se konstruiralo spiralno kućište vodne turbine. Postupak modeliranja je objašnjen korak po korak, kao i teorijske osnove vodnih turbina i samog spiralnog kućišta. Prikazane su i formule za osnovne veličine, koje su bile potrebne pri konstrukciji. Za provedbu praktičnog dijela završnog rada korišten je program CATIA. CATIA je CAD/CAM program koji uvelike olakšava inženjerski posao. Završni model je na kraju rada grafički prikazan.This thesis shows the way in which the spiral casing of the water turbine was constructed. The modeling process is explained step by step, as well as the theoretical foundations of water turbines and the spiral housing itself. The formulas for the basic quantities, which were needed during the construction, are also presented. The program CATIA was used to execute the practical part of the final work. CATIA is a CAD / CAM program that greatly facilitates engineering work. The final model is graphically presented at the end of the paper
