Análise Vibracional do Rotor Principal do Helicóptero Airbus H225M

Abstract

This work focuses on investigating the vibrational behavior of the fundamental rotational components of the Airbus H225M helicopter. The introduction to the study offers a comprehensive overview of the aircraft's key systems, providing a context for understanding its vibrational behavior. The main objective of the research is to explore and understand the balance of the main rotor, altering possible unwanted vibrations that could impact the aircraft's performance and safety. The methodology employed includes the use of the Rotation and Vibration Monitoring System (MARM’S) for a detailed analysis and collection of important data on rotor vibrations. Throughout the investigation, the results of the vibrational analysis are presented, highlighting the crucial role of MARM’S in identifying irregularities and guiding corrective maintenance actions. The conclusion of the study emphasizes the results obtained after the adjustments, indicating that the final vibration values were reduced to acceptable normal levels as per the design. These positive outcomes attest to the effectiveness of corrective maintenance in balancing the main rotor, successfully concluding the process of normalizing unwanted vibrations. Furthermore, the study contributes to a deeper understanding of the specific vibrational behavior of the Airbus H225M and highlights the relevance of MARM’S as an advanced tool in optimizing vibrational performance and predictive mainte-nance of helicopters in this category.
