    摘要: A flameholder for an augmentor rotates about an axis radially positioned with a turbine engine. The flameholder is in a streamlined position when the augmentor is not operating to minimize pressure loss and radar cross-section and a turbulent position when the augmentor is operating. A linkage connects the flameholder to an actuator to control the rotational position of the flameholder on the axis. Bypass airflow from the fan cools the flameholders and linkages. The length of the linkages can be varied from one flameholder to another to create asymmetric heat release within the augmentor to avoid screech.

    摘要: A gas turbine or rocket engine hot section includes a first duct case, a second duct case, a plurality of vanes arranged about an axial centerline, and an igniter located with a first of the plurality of vanes. The first of the plurality of vanes extends axially between a leading edge and a flame holder surface at a trailing edge. The flame holder surface extends radially between a first vane end connected to the first duct case and a second vane end connected to the second duct case. The flame holder surface includes a first section that tapers towards the first vane end, and a second section that tapers away from the first section and towards the second vane end.
