Abstract:

The present application provides an acoustic nozzle for an inlet bleed heat system using a flow of compressor discharge air. The acoustic nozzle may include an outer casing, an acoustic attenuation medium within the outer casing, a number of exit apertures positioned in the outer casing, an air pipe in communication with the outer casing, and a reduced flow area positioned about the outer chamber and the air pipe for the flow of compressor discharge air.
