US Patent 10977877 Engine gateway with engine data storage

An engine gateway of a gas turbine engine of an aircraft includes a communication interface configured to wirelessly communicate with an offboard system and to communicate with an engine control of the gas turbine engine, a memory system, a data storage system isolated from the memory system, and processing circuitry. The processing circuitry is configured to establish communication with the engine control on a first communication bus using system credential authentication, establish communication between the engine control and the data storage system on a second communication bus, establish wireless communication with the offboard system using system credential authentication, and provide access from the offboard system through the engine gateway, from the engine gateway through the engine control, and from the engine control to the data storage system to enable one or more updates of the data storage system by the offboard system based on service credential authentication.
