Abstract
Official abstract text for this publication.
A slinger combustor has an annular combustor shell defining a combustion chamber having a radially inner fuel inlet for receiving a spray of fuel centrifuged by a fuel slinger. The combustion chamber has a fuel atomization zone extending radially outwardly from the fuel inlet and merging into a radially outwardly flaring expansion zone leading to a combustion zone. A plurality of nozzle air inlets are defined in the fuel atomization zone of the combustor shell. The nozzle air inlets have a nozzle axis intersecting the stream of fuel and a tangential component in a direction of rotation of the fuel slinger. A plurality of dilution holes are defined in the combustor shell and have a dilution axis intersecting the combustion zone. The dilution axis of at least some of the dilution holes has a tangential component opposite to the direction of rotation of the fuel slinger.
First claim
Opening claim text (preview).
What is claimed is: 1. A slinger combustor for a gas turbine engine, the slinger combustor comprising: an annular combustor shell concentrically disposed about a central axis and defining an annular combustion chamber having a radially inner annular fuel inlet for receiving a spray of fuel centrifuged by a fuel slinger mounted for rotation about the central axis, the combustor shell having front and rear annular liners, a fuel atomization zone extending radially outwardly from the…
