Abstract

Cilj ovog rada bio je izraditi geometrijski model u programskom paketu MATLAB koji bi u kombinaciji s izrađenom računalnom implementacijom metode vrtložne rešetke davao koeficijente aerodinamičke sile uzgona, induciranog otpora i momenta valjanja noseće površine složene geometrije i/ili noseće površine s otklonjenim upravljačkim površinama. Kontrolne površine uvedene su kao deformacija mreže u geometriji. Nakon izrade modela geometrije, analiza je provedena za odabrano krilo složene geometrije noseće površine bez otklonjenih kontrolnih površina, a zatim s otklonom istih. Iz analize su se dobili aerodinamički koeficijenti, te koeficijenti tlaka prikazani na način prikladan za proračune čvrstoće. Dobiveni rezultati uspoređeni su s koeficijentima dobivenim iz već postojećih i dostupnih podataka dobivenih eksperimentalnim putem i analitičkim metodama.

Abstract (english)

The aim of this thesis was to create a geometry model in the MATLAB software package, which would, in return, combined with a created MATLAB implementation of vortex lattice method give the user aerodynamic lift coefficient, induced drag coefficient and rolling coefficient of a lifting surface with complex geometry and/or lifting surface with deflected control surfaces. Control surfaces were introduced in the form of deformation in the geometry grid. After the geometrical model was built, an analysis was carried out on the chosen complex geometry lifting surface with control surfaces not deflected, and then with the surfaces deflected. Aerodynamic and pressure coefficients, suitable for further strength analysis, were obtained from this analysis. The results were compared with already existing ones obtained by experiments and analytical methods.
