Abstract

U ovom radu prikazana je numerička analiza NACA laminarnih aeroprofila. Svođenjem
debelih aeroprofila na srednju liniju pomoću teorije tankih aeroprofila određena je vrijednost idealnog napadnog kuta. Zatim, koristeći metodu kontrolnih volumena i 2D panelnu metodu implementiranu u XFOIL-u, određena su aerodinamička svojstva ispitnih aeroprofila s naglaskom na drag bucket. Konačno, numerička rješenja svojstava aeroprofila uspoređena su s dostupnim eksperimentima, a interpolacijom radijalnim baznim funkcijama i polinomijalnom linearnom regresijom obrađeni su prikupljeni podaci.

Abstract (english)

This thesis focuses on numerical analysis of NACA laminar airfoils. First of all, thick airfoils are reduced to main line by thin airfoil theory in order to analytically determine the ideal angle of attack. The aerodynamic properties of airfoils are determined using the Finite Volume Method and the 2D panel method implemented in XFOIL with emphasis on drag bucket analysis. Finally, numerical solutions of aerodynamic properties are compared to available measurements and gathered data is processed by means of radial basis function interpolation and polynomial linear regression.
