Abstract

Male bespilotne letjelice u novije vrijeme nalaze važnu ulogu u poljoprivredi. Opremljene fotografskim i senzorskim uređajima, agronomima i poljoprivrednicima omogućuju preciznije planiranje i upravljanje aktivnostima. U ovome radu aerodinamički se izučava jeftino i lako izradivo leteće krilo, potencijalna "open source" alternativa komercijalnim poljoprivrednim dronovima. Provodi se detaljna aerodinamička analiza letjelice, prvo osnovnog krila bez pogonskih elemenata, a zatim i pogonjenog leta. Opisuje se i implementira metoda za postprocesiranje cirkulacije krila i izračun induciranog otpora. Pokazuje se kako aktivni propeleri utječu na aerodinamičke karakteristike letjelice. Naposljetku, vrši se procjena performansi.

Abstract (english)

In recent times, small UAVs have assumed an important role in agriculture. Equipped with imaging and sensing devices, they enable agronomists and farmers to plan and manage their operations more accurately. This thesis studies the aerodynamics of a cheap and easily made flying wing, a potential "open source" alternative to commercial drones. A thorough aerodynamic analysis of the aircraft is conducted, first of the basic wing with no propulsion and then of powered flight. A method for wing circulation postprocessing and induced drag calculation is described and implemented. It is shown how active propellers affect the aerodynamic characteristics of the aircraft. Finally, a performance assessment is made.
