Abstract

Dostupnost materijala za izradu letjelica s izrazito vitkim krilima povećava njihovu potražnju. Vitka su krila sklona značajnoj elastičnoj deformaciji koja utječe na letne karakteristike. U sklopu ovoga rada implementiran je Euler-Bernoullijev gredni model sa stupnjevima slobode savijanja i torzije. Implementirana je korekcija za aksijalan pomak uzrokovan rotacijom krila. Osnovna stacionarna aeroelastična zadaća napravljena je pomoću metode konačnih elemenata (MKE) implementacije Euler-Bernoullijeva grednoga modela te dostupne numeričke implementacije Pistolesi-Weissingerove metode noseće linije.

Abstract (english)

Availability of materials needed for highly slender wings is widening their demand. Slender wings are prone to significant elastic deformation which affects flight characteristics. In scope of this work Euler-Bernoulli beam has been implemented, with bending and torsion degrees of freedom. Correction for axial displacement caused by wing rotation has been implemented. Basic stationary aeroelastic analysis has been made using finite element method (FEM) implementation of Euler-Bernoulli beam model and available numerical implementation of numerical Pistolesi-Weissinger lifting line method.
