Title

Materials and analyses imposed in helicopter rotor blade vibrations: Review

Abstract

The aerospace industries focus on the vibration analysis of the components; it causes malfunction of the system and, in extreme condition, causes catastrophic failure. The helicopter comprises several issues primarily caused due to vibrations. In the vibrations issue, the failure due to resonance phenomena is a significant concern. The other problems caused due to vibration are fatigue failure, operator discomfort, components, uneven wear, and poor stealth performance. The primary source of vibration in a helicopter is the primary rotor system (i.e., rotor blade). The resonance depends on the natural frequency of the material, and natural frequency depends on material stiffness and mass. In order to reduce the occurrence of resonance, the rotor blade must be designed with low mass and high stiffness principle. The composite materials comprise the high strength to weight ratios, which makes them ideal for application in the rotor blade. This paper provides a review of the materials applied and vibration analyses utilized for the helicopter rotor blade. The purpose of vibration analyses is to measure or evaluate the vibrational characteristics of any components, so the methods applied for it are included in the review. The methods for vibration analysis, such as modal analysis, operational modal analysis (O.M.A.), Fast Fourier Transform (FFT) analysis, Spectral Power Density (S.P.A.) Analysis, spectrum analysis, and other experimental analyses are studied for the review. It was discovered that the composite materials consist of higher natural frequencies than the metal alloys, and the modal analysis was the most utilized method for vibration analysis.
