A RECENTLY concluded UK project has shown the potential of monitoring rotor blade behaviour in real time, researchers say. The £2m BladeSense development involved Airbus Helicopters UK and two Cranfield University departments, the Dynamics, Simulation and Control Group and the Centre for Engineering Photonics. Fibre-optic sensors measuring only microns in diameter, were put onto each blade of H135, G-POLU (c 215), for a series of ground tests. These sensors transmitted data to a remote ground station through a Wi-Fi link, using specially designed instrumentation mounted on top of the rotor hub. Information extracted from the sensors enabled the blade's shape and loads to be measured in real time.
