Abstract

The present application provides a pilot manifold system for a combustor of a gas turbine engine. The pilot manifold system may include a casing with a casing manifold, an end cover connected to the casing and having an end cover passage in communication with the casing manifold, and a fuel nozzle mounted about the end cover. The fuel nozzle may include a pilot system in communication with the end cover passage.

First claim

We claim:

1. A pilot manifold system for a combustor of a gas turbine engine, comprising:
a casing extending along and surrounding a combustion chamber, the casing comprising a first internal casing manifold connected to a second internal casing manifold by a pass-through hole configured to send air from the first to the second internal manifold;
an air inlet in communication with the first internal casing manifold and configured to receive air from outside the casing;
an end…
