Abstract

A propulsion system (20) includes a propulsor (26), an engine (22), an electrical assembly, a controller (28), and an uncontrollable high thrust (UHT) protection assembly. The engine (22) includes a fuel system (38). The engine (22) is coupled with the propulsor (26). The fuel system (38) includes a fuel control unit. The electrical assembly includes an electric motor (62) and a motor control unit (64). The electric motor (62) is coupled with the propulsor (26). The motor control unit (64) is electrically connected with the electric motor (62). The controller (28) includes a first controller channel. operable to control the fuel control unit to direct fuel to the combustor (40) and to control the motor control unit (64) to direct electrical power to the electric motor (62). The UHT protection assembly includes a first protection circuit operable to identify a presence or an absence of a UHT condition of the propulsor (26) and, in response, generate a shutdown signal for the fuel control unit and the motor control unit (64).
