Area of Science:
- Aviation Engineering
- Mechanical Engineering
- Data Science
Background:
- Military helicopter transmissions, like the H225M, face significant dynamic loads.
- Wear and fatigue in gearboxes cause ferromagnetic particle detachment, posing safety risks and increasing maintenance needs.
Purpose of the Study:
- To apply machine learning algorithms for predicting ferromagnetic particle detachment in helicopter transmissions.
- To enhance operational safety and maintenance efficiency for the Brazilian H225M fleet.
Main Methods:
- Utilizing data from the Flight Data Recorder (FDR) and Health and Usage Monitoring System (HUMS).
- Implementing pre-processing techniques for effective machine learning model application.
- Developing predictive models to forecast particle detachment events.
Main Results:
- Demonstrated the feasibility of using FDR and HUMS data for predicting particle detachment.
- Identified key indicators and patterns associated with gearbox wear and particle release.
