Abstract
A gas turbine engine () having a pressure-rise combustor () and the pressure-rise combustor () is positioned upstream of a stage of turbine nozzle guide vanes (). The vanes () of the stage of turbine nozzle guide vanes () forms an ejector and each of the vanes () has an upstream portion () and a downstream portion (). The upstream portions () of the vanes () have leading edges () and the upstream portions () are arranged substantially straight and parallel to define constant area mixing passages () for a flow of gases there-through. The downstream portions () of the vanes () are arranged at an angle to the upstream portions () of the vanes () to turn the flow of gases there-through.
