Abstract
A gas turbine engine may include a fuel manifold extending circumferentially around a diffuser case of the gas turbine engine. The fuel manifold may include a fuel supply inlet interface for receiving fuel into the fuel manifold and a plurality of fuel delivery outlet interfaces for delivering fuel to a combustor of the gas turbine engine. The gas turbine engine may also include a valve coupled to the fuel manifold. The valve may be configured to control fuel distribution in the fuel manifold. The valve may be disposed between two fuel delivery outlet interfaces of the plurality of fuel delivery outlet interfaces. The valve may be configured to at least decrease fuel flow to one of the plurality of fuel delivery outlet interfaces. The valve may be configured to at least decrease fuel flow to half of the plurality of fuel delivery outlet interfaces.
