Abstract

Cilj ovog završnog rada je analizirati uzdužnu statičku stabilnost i ravnotežni let ultra-lakog zrakoplova za različite uvjete leta. Analizom se ostvaruje uvid u dio mogućnosti uporabe zrakoplova. Ultra-laki zrakoplov, koji se razmatra, predstavlja repliku zrakoplova Zlin XII. Nakon definirane geometrije, određeni su ukupni stacionarni koeficijenti normalne sile i momenta propinjanja čime je određen aerodinamički model. Određivanjem koeficijenata, omogućena je provjera statičke stabilnosti i analiza ravnotežnog leta. Osim toga, napravljena je procjena maksimalnog koeficijenta sile uzgona i maksimalnog napadnog kuta krila.

Abstract (english)

The aim of this thesis is to analyze the longitudinal static stability and trimmed flight of ultra-light aircraft for different flight conditions. The analysis gives us better insight into some possibilities of the aircraft. Ultra-light aircraft, which is being considered, is a replica of the aircraft Zlin XII. After the geometry of the aircraft is defined, a total steady normal force and pitching moment coefficients are determined. This defined aerodynamic model for this work. Determined coefficients allows verification of static stability and trim analysis. In addition, the maximum lift coefficient and maximum angle of attack of wing is also determined.
