Abstract (Croatian)

Sadržaj ovog rada sastavljen je od dvije cjeline. Prva cjelina prikazuje osnovne konstrukcijske elemente krila. Naglasak u prvoj cjelini je na prikazu različitih izvedbi osnovnih konstruktivnih elemenata krila, njihovoj povezanosti i materijalu od kojeg su izrađeni. Druga cjelina se sastoji od numeričkog proračuna pojednostavljene konstrukcije strelastog krila. Proračun je proveden u programskom paketu Abaqus/Standard, dok je geometrija konstrukcije napravljena u programskom paketu Solidworks. Prilikom numeričke analize, u razmatranje su uzete inercijske sile kao i rasterećenje od goriva i motora. Pri tome su provedene analize za kritične točke u Vn dijagramu u pozitivnom i negativnom području, a procijenjena je mogućnost pojave plastičnih deformacija s obzirom na Von Mises ekvivalentno naprezanje.

Abstract

The content of this work is divided into two logical units. The first section shows the basic wing structural elements. The emphasis in the first part will be to illustrate the different designs of the basic structural elements, their details of the assembly and the material from which they are manufactured. The second section consists of the numerical structural simulation of the simplified structure of the swept wing. The analysis was performed in the Abaqus/Standard program package, while the geometry was made in the Solidworks program package. The numerical analysis includes the effects of inertia forces, as well as the effect of stress release due to the weight of the fuel and engine. The structural analyses were performed at the critical-points in the Vn diagram in the positive and negative loading. Furthermore, the possibility of occurrence of plastic strains using Von Mises equivalent stress was performed in this work.
