HIGH ALTITUDE STARTING OF A GAS TURBINE USING FUEL PULSATION AND STARTER ACTIVATION

摘要

A system for starting a gas turbine engine includes an engine controller and a fuel controller. The engine controller varies the engine speed between a minimum start speed and a maximum start speed until light-off of the engine occurs. The fuel controller operates a fuel command to vary fuel provided to a combustion chamber of the engine until light-off of the engine occurs.
