Claim 6:
7. 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 wirelessly 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, wherein the communication adapter is configured to communicate with an engine control of the gas turbine engine and to communicate wirelessly with an offboard system using a different frequency spectrum than the data concentrator and the wireless sensors;
storing a data set in the communication adapter based on the wireless sensor data;
transmitting the data set wirelessly from the communication adapter to an offboard system based on a transmit condition;
forming an enhanced data set at the communication adapter based on the wireless sensor data, a plurality of internal sensor data of the communication adapter, and a plurality of engine control parameters from the engine control of the gas turbine engine;
transmitting the enhanced data set to the offboard system; and
transmitting the enhanced data set to the engine control of the engine over a wired connection.
