Abstract
U ovom diplomskom radu izvršena je CFD analiza strujanja zraka oko elisa drona sa dvije različite geometrije kako bi se usporedio utjecaj oblika lopatice obzirom na aerodinamičku efikasnost. Geometrija prve lopatice je dobivena uzimanjem uzoraka aeroprofila na 5 različitih presjeka već postojeće lopatice, te su digitalizacijom dobivene točke pomoću kojih se modeliraju aeroprofili i cijela elisa drona. Izvršene su 2D i 3D CFD simulacije u svrhu određivanja sile uzgona. Zadnji korak je generiranje modificirane geometrije i uspoređivanje rezultata s onom već postojećom. Ovakva istraživanja se provode zbog povećanja mogućeg vremena leta i jako je zanimljivo što postojeća geometrija korištena u ovom radu ima tako specifičan oblik što upućuje na to da se prilikom razvoja iste napravio veliki broj simulacija ili eksperimenata jer takav oblik nije slučajan. 3D simulacija je bliža stvarnosti pa su i rezultati dobiveni modelom simulacije koji je primijenjen bolji od rezultata dobivenih 2D simulacijom.
Abstract (english)
In this thesis, a CFD analysis of the air flow around the propeller of a drone with two different geometries was performed in order to compare the influence of the blade shape with regard to aerodynamic efficiency. The geometry of the first blade was obtained by taking airfoil samples on 5 different cross-sections of the already existing blade, and the points used to model the airfoils and the entire propeller of the drone were obtained by digitalization. 2D and 3D CFD simulations was performed in order to obtain the lift force. The last step is to generate the modified geometry and compare the results with the existing one. Such research are done to increase the possible flight time and it is very interesting that the existing geometry used in this work has such a specific shape that indicates that during its development a large number of simulations or experiments were made because such a shape is not random. 3D simulation is closer to reality, so the results obtained by the applied simulation model are better than the results obtained by 2D simulation.
