Abstract

Završni rad obrađuje temu aerodinamičkih karakteristika letećih krila. Objašnjena je njihova povijest u svrhu razumijevanja početaka i motivacije za njihov razvoj. Za obradu podataka korišten je računalni program XFLR5. U njemu su napravljene aerodinamičke analize na odabranim aeroprofilima i modelu letećeg krila temeljenog na stvarnom zrakoplovu. Objašnjeni su osnovni aerodinamički principi važni za razumijevanje analiza i prikazivanje posebnosti, prednosti i nedostataka letećih krila u odnosu na klasične zrakoplovne konfiguracije. Također su iznijeti razlozi njihove upotrebe u vojne svrhe te zašto još uvijek nisu zastupljeni u civilnom zrakoplovstvu. Na kraju su prikazana završna razmatranja s budućim izgledima razvoja letećih krila.

Abstract (english)

This paper deals with the topic of the aerodynamic characteristics of flying wings. A brief history of flying wings is first presented in order to understand their beginnings and the motivation behind their development. The program XFLR5 is used to perform aerodynamic analyzes on select airfoils and a flying wing model based on a real aircraft. The basic aerodynamic principles important to understanding the analyzes and showing the peculiarities, advantages and disadvantages of flying wings in comparison to normal aircraft configurations are explained. The reasons behind their use for military purposes and why they are still not present in civil sectors are also presented. In the end, the final considerations with the future outlook of the development of flying wings are presented.
