Abstract

Cilj ovog završnog rada je izvršiti analizu optjecanja zraka oko noseće površine primjenom metode vrtložne rešetke. Analiza podrazumijeva proračun koeficijenata aerodinamičke sile uzgona i sile induciranog otpora za noseću površinu odabrane geometrije i profila. Do spomenutih koeficijenata se dolazi računalnom implementacijom, u radu i teorijski opisane, metode vrtložne rešetke u programskom jeziku MATLAB. Provedena je usporedba rezultata dobivenih na temelju analize različitih geometrija nosećih površina u MATLAB-u s rezultatima koji se dobivaju korištenjem programskog paketa XFLR5. Također, provedena je i analiza aerodinamičkih koeficijenata noseće površine odabrane geometrije s otklonjenom upravljačkom površinom.

Abstract (english)

The aim of this paper is to perform an analysis of airflow around a lifting surface using the vortex lattice method. The analysis involves calculating the aerodynamic coefficients of lift and induced drag for a lifting surface with a selected geometry and airfoil. These coefficients are obtained through the computational implementation of the vortex lattice method, which is theoretically described in the paper, using the MATLAB programming language. A comparison was conducted between the results obtained from the analysis of different geometries of lifting surfaces in MATLAB and those obtained using the XFLR5. Additionally, an analysis was conducted on the aerodynamic coefficients of the lifting surface with a deflected control surface for the selected geometry.
