Abstract:V diplomskem delu se je analiziralo aerodinamično obnašanje preobraznega krila pri različnih vpadnih kotih. S programom ANSYS FLUENT so bile izračunane spremembe koeficienta upora in vzgona ter primerjane pri pogojih lebdenja in križarjenja. Dodatno je bil preučen vpliv gostote računske mreže na koeficiente vzgona, pri čemer je bila določena optimalna velikost mreže – 1,7 milijona elementov, pri kateri so se vrednosti stabilizirale. Na tej osnovi so bili analizirani različni vpadni koti in spremljane so bile spremembe aerodinamičnih lastnosti. Ugotovljeno je bilo, da režim letenja vpliva minimalno, medtem ko ima največji vpliv vpadni kot (preboj pri 14°). Rezultati so se stabilizirali pri 1,7 milijona elementov mreže in so sledili trendom analitičnega izračuna ob ohranjeni stalni razliki.

Title:Cfd numeric simulation of a morphing wing
Abstract:In the thesis, the aerodynamic behavior of the morphing wing at various angles of attack was analyzed. Using ANSYS FLUENT, changes in the drag and lift coefficients were calculated and compared under hovering and cruising conditions. Additionally, the influence of the computational mesh density on the lift coefficients was examined, with the optimal mesh size determined to be 1.7 million elements, at which the values stabilized. Based on this, different angles of attack were analyzed and changes in aerodynamic characteristics were monitored. It was found that the flight regime has a minimal effect, while the angle of attack has the greatest influence (with a critical point at 14°). The results stabilized at 1.7 million mesh elements and followed the trends predicted by line lifting theory with a constant offset maintained.
Keywords:morphing wing, ANSYS Fluent, angle of attack, drag, lift
