Abstract

Ovaj završni rad analizira uzdužnu statičku stabilnost i ravnotežni let bespilotne letjelice konfiguracije letećeg krila. Usvojena je geometrija i za nju su primjenom metodologije projektne aerodinamike i empirijskih metoda procijenjeni stacionarni aerodinamički koeficijenti normalne sile i momenta propinjanja, uzdužna statička stabilnost te ravnotežni let za različite konfiguracije i uvjete leta. U svrhu verifikacije proračuna provedena je numerička analiza u programu XFLR5, gdje su dobiveni rezultati uspoređeni s proračunom provedenim metodom projektne aerodinamike. Cilj ovog rada je pružiti uvid u stabilnost i uvjete ravnotežnog leta letjelice u različitim konfiguracijama i uvjetima leta.

Abstract (english)

This final thesis analyzes the longitudinal static stability and equilibrium flight of an unmanned aerial vehicle with a flying wing configuration. The adopted geometry was evaluated using aerodynamic design methodology and empirical methods to estimate the steady aerodynamic coefficients of normal force and pitching moment, as well as longitudinal static stability and equilibrium flight for different configurations and flight conditions. To verify the calculations, a numerical analysis was conducted using the XFLR5 software, where the obtained results were compared with the calculations performed using the aerodynamic design method. The aim of this thesis is to provide insight into the stability and equilibrium flight conditions of the aircraft in various configurations and flight conditions.
