Claim 0:
1. A wireless sensor system of a gas turbine engine of an aircraft, the wireless sensor system comprising:
a plurality of wireless sensors distributed within an engine core of the gas turbine engine;
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;
a data concentrator coupled to the gas turbine engine, the data concentrator configured to wirelessly receive a plurality of wireless sensor data from the wireless sensors and transmit the wireless sensor data 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; and
the communication adapter is configured to:
form an enhanced data set 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;
transmit the enhanced data set to the offboard system; and
transmit the enhanced data set to the engine control of the engine over a wired connection.
