Research abstract
This proposal describes a compact fiber-optic strain interrogator and data logging system suitable for installation with the rotating components of helicopters. The system uses Brillouin scattering in an optical fiber to track fiber strain and the corresponding strain in material where the fiber is embedded. The objective is to monitor the mechanical condition of high-stress parts such as rotor blades while the aircraft is in flight. Rotor blade stress information accumulated this way will be available wirelessly to maintenance crews, and will support a condition-based maintenance program. The interrogator is highly self-contained and configurable to acquire as much data as possible using limited power available to it through energy harvesting.
