THE MODAL ANALYSIS OF A CARBON FIBER HELICOPTER BLADE
Journal Title: Journal of Industrial Design and Engineering Graphics - Year 2015, Vol 10, Issue 2
Abstract
The blade and the rotor’s components belong to the helicopter’s vital parts, parts that if they fail or if they malfunction it will result inevitably in the total destruction of the flying machine. The vibrations are dynamic phenomena usually encountered in the aerospace area, especially for blades and wings in use. The scope of the paper is to determine the characteristic frequencies in order to establish the occurrence possibility of the resonance phenomena. The modal analysis allows for quite a precise investigation of the behavior of a helicopter blade accounting for aspects like specific geometry of the blade, the coupling between the blade and the rotor hub and also for the blade material.
