Obid, Štefan (author), Boltežar, Miha (mentor), Čepon, Gregor (co-mentor)

Helikopterska elisa je ključen del helikopterja, ki generira dvižno silo potrebno za letenje. Cilj zaključne naloge je analiza dinamskega odziva elise pri različnih vrstah vzbujanja. Postavili smo poenostavljen fizikalni model elise, ki sestoji iz končnega števila togih teles. Na podlagi metode, ki temelji na Lagrange-d'Alembertovem principu virtualnega dela, smo izpeljali gibalne enačbe ter izvedli simulacijo. V rezultatih so obravnavane hitrosti in deformacije helikopterske elise, ki se pojavijo pri različnih vrstah vzbujanja.

• Title: Dynamic response of the Helicopter Propeller

Abstract

Helicopter propeller is key part of helicopter, which generates lift force needed for flying. Main objective of final thesis is dynamic response analysis of propeller for different types of excitations. A simplified physical model of the propeller was set, which consists of the final number of rigid bodies. On the basis of the Lagrange-d'Alembert principle of the virtual work, we derived equations of motion and performed a simulation. In the results the speed and deformation of helicopter propeller is demonstrated that occurs due to the different types of loads.
