Abstract:
1. A method for wirelessly monitoring an aircraft propulsion system, comprising: providing a plurality of rotor blades for the aircraft propulsion system, at least some of which rotor blades have an internal compartment; providing a primary transducer having a primary coil, and a plurality of secondary transducers, each secondary transducer having a secondary coil connected to a sensor, wherein the secondary transducers are respectively disposed within the internal compartments; wirelessly powering the secondary transducers using a magnetic field generated by the primary transducer; monitoring at least one operational parameter from within each internal compartment using a respective sensor; transmitting a synchronization signal from the primary transducer to the secondary transducers through the magnetic field; and transmitting output signals from the secondary transducers to the primary transducer through the magnetic field as a function of the synchronization signal, wherein the output signals are indicative of the monitored parameters.
