Abstract
An assembly for a turbine engine includes a vane structure, a wall and an air delivery device. The vane structure includes an inner platform, an outer platform and a plurality of vanes arranged circumferentially about an axis. The inner platform extends circumferentially about the axis and forms an inner peripheral boundary of a flowpath through the vane structure. The outer platform extends circumferentially about the axis and forms an outer peripheral boundary of the flowpath through the vane structure. The vanes extend across the flowpath from the inner platform to the outer platform. The wall extends circumferentially about the axis. The wall is radially outboard of the vane structure with a cavity formed by and radially between the outer platform and the wall. The air delivery device is disposed within the cavity. The air delivery device is configured to direct cooling air into the cavity along the outer platform.
