Abstract

A method is provided for wirelessly monitoring an aircraft propulsion system having a plurality of rotor blades (20, 36), at least some of which rotor blades (20, 36) have an internal compartment (22, 38). The method includes: providing a primary transducer (42) having a primary coil (48), and one or more secondary transducers (44), each secondary transducer (44) having a secondary coil (74) connected to a sensor (78), wherein the secondary transducers (44) are respectively disposed within the internal compartments (22, 38); wirelessly powering the secondary transducers (44) using a magnetic field generated by the primary transducer (42); monitoring at least one operational parameter from within each internal compartment (22, 38) using a respective sensor (78); and transmitting output signals from the secondary transducers (44) to the primary transducer (42) through the magnetic field, wherein the output signals are indicative of the monitored parameters. The propulsion system may be a gas turbine engine (10) or a rotor of a rotary wing aircraft (24).
