摘要： An engine gateway (102) of a gas turbine engine (104) of an aircraft (108) includes a communication interface (216) configured to wirelessly communicate with an offboard system (106) and to communicate with an engine control (122) of the gas turbine engine (104), a memory system (212), a data storage system (236) isolated from the memory system (212), and processing circuitry (220). The processing circuitry (220) is configured to establish communication with the engine control (122) on a first communication bus (232) using system credential authentication, establish communication between the engine control (122) and the data storage system (236) on a second communication bus (234), establish wireless communication with the offboard system (106) using system credential authentication, and provide access from the offboard system (106) through the engine gateway (102), from the engine gateway through the engine control (122), and from the engine control (122) to the data storage system (236) to enable one or more updates of the data storage system (236) by the offboard system (106) based on service credential authentication.

摘要： A communication system of a gas turbine engine for an aircraft includes an engine control system configured to generate engine data and a communication device. The communication device includes a memory system and a communication interface configured to wirelessly communicate with an offboard system external to the aircraft and to communicate with the engine control system and the memory system. The communication interface is further configured to receive the generated engine data from the engine control system. The communication device further includes processing circuitry configured to selectively record the generated engine data, determine a location of the gas turbine engine, determine a data management strategy based on the determined location, and transmit, using the communication interface, a first portion of the recorded engine data to the offboard system. A data content of the first portion of the recorded engine data is based on the data management strategy.

摘要： A wireless sensor system (205) of a gas turbine engine (104) of an aircraft (108) can include a plurality of wireless sensors (207) distributed within an engine core (115) of the gas turbine engine (104) and an energy harvesting system (213) including one or more energy harvesting devices (215) configured to convert mechanical or thermal energy within the gas turbine engine (104) into electric power and provide the electric power to the wireless sensors (207). The wireless sensor system (205) can also include a data concentrator (209) coupled to the gas turbine engine (104). The data concentrator (209) can be configured to receive a plurality of wireless sensor data from the wireless sensors (207) and transmit the wireless sensor data to a communication adapter (102) of the gas turbine engine (104).
