Abstract
Methods and systems for starting an engine are described. The method comprises a manifold purging phase where the at least one fuel manifold is filled with an inert gas; a manifold fuel filling phase, where fuel flows into the at least one manifold and blends with the inert gas as the engine rotates, and the inert gas is subsequently turned off; and an ignition phase, where the fuel flowing from the at least one manifold into the combustor is ignited and light-up is detected.
Claims22
A method for starting an engine coupled to a fuel system having at least one fuel manifold configured to supply fuel to a combustor of the engine, the method comprising:
- a manifold purging phase where the at least one fuel manifold is filled with an inert gas;
- a manifold fuel filling phase, where the fuel flows into the at least one manifold and blends with the inert gas as the engine rotates, the inert gas and the fuel allowed to flow into the at east on fuel manifold during the manifold fuel filling phase, and the inert gas is subsequently turned off;
- and
- an ignition phase, where the fuel flowing from the at least one manifold into the combustor is ignited and light-up is detected.
(canceled)
A system for starting an engine coupled to a fuel system having at least one fuel manifold configured to supply fuel to a combustor of the engine, the system comprising:
- a processor;
- and
- a non-transitory computer-readable medium having stored thereon program code executable by the processor for:
- a manifold purging phase where the at least one fuel manifold is filled with an inert gas;
- a manifold fuel filling phase, where the fuel flows into the at least one manifold and blends with the inert gas as the engine rotates, the inert gas and the fuel allowed to flow into the at least one fuel manifold during the manifold fuel filling phase, and the inert gas is subsequently turned off;
- and
- an ignition phase, where the fuel flowing from the at least one manifold into the combustor is ignited and light-up is detected.
