Title:: ROTORBLADE SHAPE ESTIMATION WITH FIBER-OPTICAL SENSORS FOR A HEALTH AND USAGE MONITORING SYSTEM
Abstract:: The increasing maturity and decreasing size of the measurement equipment enables Fiber Bragg Grating (FBG) sensors to be used for structural monitoring of complex structures. FBGs applied on helicopter rotor blades are used to identify blade movements, which will serve as a valuable data source to supply Usage Monitoring Systems for rotorcraft. In this paper, a modified approach is presented that calculates the displacement of a rotor blade with nonuniform cross sections in two dimensions, based on surface strain measurements with FBGs. Furthermore, the effect of different boundary conditions and sensor combinations is analyzed. «
