New real-time structural health monitoring microsystem for aircraft propeller blades

This presents work done on the project “Blade Parameters Recording Microsystem” funded by the French research program FUI. It resulted in a fully operational recorder that can be embedded on a plane. This system allows blade monitoring to be conducted using computing algorithms. Using a top-down modelling method, this recorder can be adapted to any kind of blade. Herein, recorder was devised for a Transall plane blade. This device was used to record data in order to subsequently compute a real-time blade monitoring algorithm. The algorithm takes several blade parameters into account. The top-down modelling easily allows the algorithm parameters to be adapted to various blades.
