Abstract

U ovom završnom radu analiziraju se performanse zrakoplova nove generacije kojega pokreće električna energija. Za primjer zrakoplova na kojemu će se zasnivati analiza uzet je poslovni električni zrakoplov Alice iz izraelske tvrtke Eviation. U početnom djelu rada istraženi su dostupni podaci te se pomoću njih oblikuje tražena geometrija koja je od važnosti za daljnje proračune. Podatke koji nisu nađeni bilo je potrebno procijeniti pomoću literature te usporedbom sa zrakoplovima sličnih... More performansa. Definiranom geometrijom kreće se u proračun procjene otpora koji se vrši superpozicijom otpora za pojedine dijelove modela zrakoplova. Osim procjene otpora pažnja se posvećuje opisu pogonskog sustava propelerskog električnog zrakoplova. Iznos otpora te karakteristika pogonskog sustava važna su stavka drugog djela završnog rada. U njemu se analiziraju performanse u horizontalnom letu temeljene na određenim pretpostavkama i provodi se analiza pomoću teorije ukupne energije. Konačno, u dijagramskim prikazima vide se dobiveni rezultati ovojnice sposobnosti djelovanja zrakoplova u horizontalnom letu. Less

Abstract (english)

In this bachelor thesis, the performance of a new generation aircraft powered by electricity is analyzed. The Alice business electric aircraft from the Israeli company Eviation was taken as an example of the aircraft on which the analysis will be based.
In the initial part of the work, the available data are researched and used to form the required geometry, which is important for further calculations. Data not found had to be assessed using the literature and compared with aircraft... More of similar performance. With the defined geometry, it moves to the calculation of the drag estimate, which is performed by the superposition of the drag for individual parts of the aircraft model. Except the drag assessment, attention is given to the description of the propulsion system of the propeller electric aircraft. The amount of drag and the characteristics of the drive system are an important item of the second part of the final work. It analyses horizontal flight performance based on certain assumptions and performs analysis using total energy theory. Finally, the diagrams show the obtained envelope results of the aircraft’s ability to operate in horizontal flight. Less
