Abstract
Cilj ovog rada je analizirati performanse bespilotne letjelice u utjecaju tla, te dobivene rezultate usporediti s performansama bespilotne letjelice bez utjecaja tla. Utjecaj tla je zanimljiva pojava koja se manifestira pri niskim visinama leta. Može imati povoljan utjecaj na aerodinamičke karakteristike letjelice, uz određena ograničenja. Najčešće je prisutan u fazama polijetanja i slijetanja, no može biti od interesa razmatrati ravnotežni let i ostale performanse bespilotne letjelice u utjecaju tla, za primjer možemo uzeti let bespilotne letjelice u blizini mora. Promatrana bespilotna letjelica dio je prošlogodišnjeg projekta ACC 2019 imena HUSZ Jaeger te su podaci o letjelici prikupljeni iz pripadajuće dokumentacije. Korištenjem programskog paketa MatLab provedena je analiza aerodinamičkih značajki s utjecajem tla i performanse stavljajući naglasak na ravnotežni let odabrane letjelice. Aerodinamičke značajke bit će procjenjene metodom noseće linije te uspoređene s nekoliko empirijskih jednadžbi.
Abstract (english)
The aim of this paper is to analyse performance of unmanned aerial vehicle under ground effect, and to compare obtained resaults with the performance of an unmanned aerial vehicle without the influance of ground effect. Ground effect is an interesting phenomenon that manifests al low altitudes. It can have a positive effect on aerodynamic characteristics of aircraft, with certain limitations. It is most often present in the take-off and landing phases of the flight, but it may be of interest to cosider trim and other performances under it's influence. For example we can take the flight of a drone near the sea. The observed unmanned aerial vehicle is part of last year's project ACC 2019 named HUSZ Jaeger and data of the aircraft is collected from the relevant documentation. Using MatLab software package, analysis was performed related to aerodynamic features, emphasizing trim, endurance and rage of the selected aircraft. The aerodynamic features will be estimated by lifting line theory and compared with several empirical equations.
