COMBUSTOR FOR GAS TURBINE ENGINE

摘要

A combustor comprises an annular combustor chamber formed between the inner and outer liners, the annular combustor chamber having a central axis. Fuel nozzles are in fluid communication with the annular combustor chamber to inject fuel in the annular combustor chamber. The fuel nozzles are oriented to inject fuel in a fuel flow direction having an axial component relative to the central axis of the annular combustor chamber. Nozzle air inlets are in fluid communication with the annular combustor chamber to inject nozzle air generally radially in the annular combustor chamber. A plurality of dilution air holes are defined through the inner and outer liner downstream of the nozzle air inlets, the dilution holes configured for high pressure air to be injected from an exterior of the liners through the dilution air holes generally radially into the combustor chamber, a central axis of the dilution air holes having a tangential component relative to the central axis of the annular combustor chamber.

1. A combustor comprising:
an inner liner; an outer liner spaced apart from the inner liner; an annular combustor chamber formed between the inner and outer liners, the annular combustor chamber having a central axis; fuel nozzles in fluid communication with the annular combustor chamber to inject fuel in the annular combustor chamber, the fuel nozzles oriented to inject fuel in a fuel flow direction having an axial component relative to the central axis of the annular combustor chamber; nozzle air inlets in fluid communication with the annular combustor chamber to inject nozzle air in the annular combustor chamber; and a plurality of dilution air holes defined through the inner and outer liner downstream of the nozzle air inlets, the dilution holes configured for high pressure air to be injected from an exterior of the liners through the dilution air holes into the combustor chamber, a central axis of each of a plurality of the dilution air holes having a tangential component relative to the annular combustor chamber, the tangential component of the central axes of the dilution air holes being oriented in a same common direction.
