INSPEÇÃO POR LÍQUIDO PENETRANTE NA HASTE DE COMANDO E ANÁLISE DE VIBRAÇÃO DO ROTOR DE CAUDA DA AERONAVE AIRBUS AS350 ESQUILO

Abstract

The present work has the objective of accomplishing a dye penetrant inspection on the tail rotor actuating rod and subsequently analyze tail rotor vibration on the aircraft AIRBUS AS350 (Esquilo). Being the helicopter known as a machine that has high levels of vibration and noise. The process of balancing your axles and rotors, routine task performed mainly after maintenance interventions, becomes even more important. It is know that a vibration control maintenance must be performed to improve crew efficiency, to provide safe operation, to provide passenger comfort, to ensure reliability of electronic and mechanical equipment and minimize aircraft rotor and fuselage fatigue. For this a quantitative research was performed, which translates the numbers that correspond to the vibrations for the classification and analysis of information, using statistical resources and techniques, as well as a bibliographic and documentary research had its great importance in this work. The penetrating liquid used was Type I (fluorescent) and the method used for vibration analysis is the sum of vectors from the vibration level indicated by the appliance Aces Model 2020 Probalancer Analyser with the accelerometers of Aces Systems model 991D-1. In conclusion, both non-destructive testing and vibration analysis are powerful tools in helping to prevent failures, lowering maintenance cost, extending the life of a helicopter and preserving the greater good that is the human factor.
