Consolidating engine related sensor interfaces in a data concentrator, located on the main engine strut, reduces wire weight from the engine to the fuselage.

The Main Engine Data Concentrator will provide up to 100 electrical interfaces to engine sensors, which include: temperature, pressure, fire, speed, proximity, resistance and discrete interfaces.

In addition to providing sensor interfaces, the Main Engine Data Concentrator performs two functions, Engine Anti-Ice and Engine Fire Detection. Engine Anti-Ice is a closed loop control system that utilizes pressure sensor inputs to control a torque motor that varies the amount of bleed air sent to the engine cowling. Engine Fire Detection uses resistive loops mounted on the engines while the Main Engine Data Concentrator determines if there is an engine fire based on their dynamic characteristics.

Each Main Engine Data Concentrator will be designed with a dual architecture providing complete separation to meet high integrity requirements. This includes separate circuit cards, separate connectors, separate power supplies and separate communication busses. A single, dual architecture Main Engine Data Concentrator will be mounted on each main engine.
