BIG-ROHU: BIG Data - Rotor Health and Usage Monitoring

In the BIG-ROHU project, a Health and Usage Monitoring System (HUMS) is being developed in collaboration with Kopter Germany GmbH and Prof. Straub’s Engineering Risk Analysis Group. The system aims to provide detailed insights into both the condition and the operational usage of helicopter components.

To achieve this, the project investigates data-driven and physics-based methods, using rotor components of Leonardo’s AW169 helicopter as a case study. The analysis is supported by experimental certification flights, operational flight data, and maintenance event statistics.

The overarching objective of the project is to reduce extraordinary maintenance activities, thereby enabling improved maintenance planning, strengthening customer confidence, and increasing fleet and aircraft availability for operators. Moreover, the enhanced HUMS system developed within the project is intended to support longer product life cycles as well as greater material and resource efficiency.
