Abstract

This master thesis is a continuation of the work on a project of aerodynamic model development for a general aviation airplane, Piper PA-28, conducted by Centre for aviation at the Zürich University of Applied Sciences. After previous flight test data processing and organizing, a basic linear model was introduced. In this thesis its improvement was made, but before improvement itself, using flight path reconstruction it is necessary to develop sensor error model, as precisely as possible. Great attention is dedicated exactly to this part. Completion of the flight path reconstruction, with corrected sensor values, using linear regression aerodynamic parameters are estimated with ordinary least square method. Focus is put on longitudinal motion, such as stall, phugoid and short period manoeuvres.

Abstract (croatian)

Ovaj diplomski radi nastavak je rada na projektu razvoja aerodinamičkog modela zrakoplova generalne avijacije, Piper PA-28, Centra za zrakoplovstvo Sveučilišta primijenjenih znanosti u Zürichu. Nakon prethodne obrade i organizacije podataka snimljenih tijekom leta, predstavljen je osnovni linearni model. U ovom diplomskom radu napravljeno je poboljšanje, ali prije samog rada na poboljšavanju modela, putem rekonstrukcije putanje leta potrebno je što preciznije obraditi model pogrešaka senzora. Velika pažnja posvećena je upravo tom dijelu. Završetkom rekonstrukcije putanje lete, s korigiranim vrijednostima senzora, primjenom linearne regresije metodom najmanjih kvadrata procjenjuju se aerodinamički parametri. Fokus je stavljen na uzdužno gibanje, poput sloma uzgona, dugo periodičnog i kratko periodičnog moda.
