Fuel supply and engine control system (fig. 9.1):
supplies fuel to the engine combustion chamber;
controls TC and free turbine (MR) RPM within required for operational power settings range;
limits maximum indicated TC RPM;
limits maximum reduced TC RPM parameter;
controls air bypass valves operation;
controls engine automatic start up;
synchronizes engines power;
controls position of engine compressor variable geometry vanes;
prevents free turbine over speeding;
automatically readjusts engine electronic governor for emergency power setting in case of single engine failure;
controls TC RPM at idle power setting.
