Fibre Bragg grating (FBG) and interferometric direct fibre-optic shape sensing (DFOSS) instrumentation were deployed on helicopter rotor blades during a full-speed ground run to provide insights into the blade dynamics. Data were streamed wirelessly from the rotor hub-mounted sensor interrogators. Changes in strain and vibration signatures in response to a series of pilot test inputs were successfully identified and high-resolution blade shape change data has been acquired.
