Abstract:Za magistersko nalogo smo izvedli proceduro za izračun geometrije lopatice vetrne turbine v Excelu. Izračun geometrije lopatice temelji na metodi »Blade element theory«, ki je del BEM metode. Razika med našo proceduro in omenejima metodama je le v tem, da je v omenjenih metodah geometrija lopatice vetrne turbine že dana. Preračunano geometrijo s pomočjo izvedenega programa prenesemo v program SolidWorks tako, da program najprej izriše krivulje profilov in jih podem s funkcijo »Loft« poveže v lopatico. Program izračuna optimalno geometrijo lopatice z upoštevanjem rotirajoče brazde, ki je modelirana v SolidWorksu. Geometrijo lopatice preračunamo le s kliki na gumbe v programu, prav tako jo s kliki na gumbe tudi modeliramo v SolidWorksu. V nalogi je natančneje predstavljeno delovanje programa.

Title:Geometry calculation of blade and transfer in cad system
Abstract:For final work we made calculation procedure for geometry of wind turbine blades in Excel. Calculation of geometry of the blade is based on »Blade element theory«, which is a part of the BEM method. The difference between this procedure and calculation procedure based on mentioned methodes is only in the fact that in calculation with BEM method, the geometry is already given. Converted geometry using the program is transferred into SolidWorks so that the program initially plotted curve profiles and then with operation "Loft" curves of profiles on sections are connected to the blade. The program calculates the optimal geometry of the blade with wake rotation and also model it in the SolidWorks. Geometry of the blade is calculated by only pressing the buttons in program and also model it in SolidWorks by pressing the buttons. The project will specifically present the work of program.
Keywords:calculation, wind turbine blade geometry, modeling
