Engine wireless sensor system with energy harvesting

A method comprising:

• providing electric power to a plurality of wireless sensors in an engine core of a gas turbine engine using an energy harvesting system in the gas turbine engine, wherein the energy harvesting system comprises one or more energy harvesting devices configured to convert mechanical or thermal energy within the gas turbine engine into electric power;
• transmitting a plurality of wireless sensor data from the wireless sensors to a data concentrator coupled to the gas turbine engine;
• transmitting the wireless sensor data from the data concentrator to a communication adapter of the gas turbine engine;
• storing a data set in the communication adapter based on the wireless sensor data;
• and
• transmitting the data set wirelessly from the communication adapter to an offboard system based on a transmit condition.

A gas turbine engine of an aircraft, the gas turbine engine comprising:

• a fan section comprising a fan case;
• an engine control mounted on the fan case, the engine control configured to monitor and control operation of the gas turbine engine in real-time;
• a communication adapter mounted on the fan case;
• an engine core;
• a plurality of wireless sensors distributed within the engine core;
• an energy harvesting system comprising one or more energy harvesting devices configured to convert mechanical or thermal energy within the gas turbine engine into electric power and provide the electric power to the wireless sensors;
• and
• a data concentrator configured to receive a plurality of wireless sensor data from the wireless sensors and transmit the wireless sensor data to the communication adapter.
