Abstract

Rad obrađuje temu raspodjele uzgona na krilu uspoređujući dva oblika distribucije uzgona, zvonoliki i eliptični. Cilj je analizirati i usporediti zvonoliku i eliptičnu raspodjelu uzgona na krilima zrakoplova kroz njihove specifičnosti i utjecaj na inducirani otpor letjelice te navedenu analizu i rezultate prikazati kroz XFLR5 program. Razlozi zbog kojih zvonolika raspodjela još nije zaživjela u komercijalnom zrakoplovstvu te njene prednosti i mane također su iznijeti kao dio rada. Rad se također dotiće povijesnog razvoja izračuna raspodjele uzgona kao i geometrije krila općenito, što je neizbježno za shvaćanje principa stvaranja i formiranja uzgona kao glavne sile koja održava zrakoplov u zraku.

Abstract (english)

This paper elaborates the lift distribution along the wing of an aircraft by comparing two types of lift distribution, bell-shaped and elliptical. The aim of the paper is to analyse and compare these two types of lift distribution trough their specifics and influence on the induced drag of an aircraft, as well as to review the results and analisys of the work trough XFLR5 computer program. Reasons for not implying the bell-shaped spanload in commercial aviation today are also a part of the paper, along with its relevant positive and negative characteristics. The work as well covered the historical development of calculating the lift distribution along the wing and wing geometry in general, as it is inevitable for one to understand the whole idea and principles that stand behind the lift force of an aircraft, its forming and distribution.
