Kokelj, Gal (author), Čepon, Gregor (mentor)

V zaključni nalogi je obravnavan dinamski model elise helikopterja in njen dinamski odziv na udarno motnjo med obratovanjem. Najprej je v nalogi predstavljen poenostavljen fizikalni model elise helikopterja, ki sestoji iz sistema togih teles, ki so povezana s torzijskimi dušilkami in vzmetmi. Sledi izpeljava gibalnih enačb, katerih sistem predstavlja numerični model obravnavanega sistema. Rezultati naloge zajemajo simulacijo vrtenja lopatice elise helikopterja in analizo odziva lopatice na udarno motnjo med obratovanjem.

• Title: Dynamics model of helicopter propeller blade based on rigid body system dynamics

Abstract

This work deals with dynamic model of helicopter propeller and its dynamic response to shock load during operation. First, a simplified physical model of the helicopter propeller is developed as a system of rigid bodies, connected with torsional dampers and springs. This is followed by the derivation of the equations of motion, system of which represents a numerical model of the system under consideration. Results of our work include the simulation of rotation of the helicopter propeller blade and the analysis of blade response to shock load during operation.
