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.
