Abstract
A centrally disposed vent is positioned adjacent the low pressure region of recirculating gases in a combustor or augmentor of the type used in gas turbine engines, allowing gas to be abstracted from the core of the recirculating region, thereby causing a reduction in static pressure, and a strengthening and stabilizing of the recirculating flow pattern. Combustion occurring in the recirculating gas is intensified by virtue of higher mixing rates, and flame stability is enhanced by virtue of increased stability of the recirculating flow pattern. The vent is shown employed in a premixing tube device for use in gas turbine engine main combustors. Alternative main combustor and augmentor combustor configurations are shown.
