초록

An electronic control system for regulating the amount of torque applied by a starter/generator to a gas turbine engine during startup. The control system senses engine speed, compares the engine's actual acceleration with a predetermined acceleration, and adjusts the torque to the engine so that the engine accelerates along the predetermined schedule. The predetermined schedule is a function of the engine's speed or time, inlet conditions and oil temperature.
