Abstract
U ovom završnom radu izrađeni su modeli aviona jedrilice i njihovo analizirano strujanje zraka preko 3D modela. Modelirane su dvije avion jedrilice u 3D programu Blender približno jednakih dimenzija. Jedna jedrilica će biti modelirana na bazi aerodinamike pravih aviona (po zakonima avionske fizike) kako bi imala puno bolji i kvalitetniji otpor zraka te kako bi bolje letjela, odnosno duže padala. Druga avion jedrilica bit će modelirana proizvoljno. Nakon toga modele će se analizirat u programu „Openfoam“, kojim će se izračunati otpori zraka i sila uzgona za oba modela. Zatim će biti provedena analiza i usporedba modela, odnosno njihovi izračuni otpora zraka (sile uzgona i sile otpora). Iz izračunatih podataka analizirat će se potrebna poboljšanja.

| Abstract in english: | In this final work, glider plane models were created and their airflow was analyzed through a 3D model. Two gliders were modeled in the Blender 3D program of approximately equal dimensions with different bodies, wings and laws of airplane aerodynamics. One glider was modeled on the basis of the aerodynamics of real airplanes (according to the laws of aircraft physics) in order to have a much better quality, or lower coefficient of resistance, and a much better quality, or higher coefficient of lift. The second glider plane will be modeled arbitrarily. After that, the models will be compared and analyzed in the "Openfoam" program, which will calculate the coefficients of resistance and buoyancy for both models. Then the analysis and comparison of the models will be carried out, respectively their air resistance calculations (buoyancy and drag forces). During the calculation, the computer assumed that the surfaces of the model are 1 and we set the speed according to the real planes of the glider, which is about 100 m/s. From the calculated data, the necessary improvements will be analyzed and we will find out which model is of better quality. |
