Abstract

Zadatak ovog Završnog rada je usporediti procijenjene mase konstrukcije krila dobivene pomoću polu-empirijskih metoda koje se koriste u preliminarnom projektiranju zrakoplova i numeričkim proračunom čvrstoće. U radu je proračun proveden programom za numeričku analizu metode konačnih elemenata Abaqus/Standard. U prvom poglavlju opisane su specifikacije zrakoplova Airbus A-320 i Boeing 747 čije su torzijske kutije krila analizirane u ovom radu. Drugo poglavlje govori o polu-empirijskoj metodi, dok je u trećem objašnjena analiza čvrstoće torzijskih kutija. Zatim slijedi usporedba rezultata dvaju metoda te zaključak gdje je cijeli rad ukratko izložen.

Abstract (english)

The task of this Bachelor thesis is to compare the estimated wing structure masses obtained using semi-empirical methods used in preliminary aircraft design and numerical strength calculation. In this work, the calculation was performed by the program for numerical analysis using the finite element method Abaqus/Standard. The first chapter describes the specifications of the Airbus A-320 and Boeing 747 aircraft whose wing boxes are analysed in this work. The second chapter introduces the semi-empirical method, while the third explains the strength analysis of the wing boxes. This is followed by a comparison of the results of the two methods and a conclusion in which the complete work is briefly presented.
