Sound transport in low-pressure turbines

As a result of the growing volume of air traffic worldwide, noise pollution has become an increasingly important factor in the development of aircraft engines. In order to be able to relieve the environment through ever quieter engines, precise knowledge of sound transport in the final engine stages is required. To this end, experiments are conducted at the Aeroacoustic Wind Tunnel (AWT) in which defined sound fields are introduced into a bladed duct. The measurement of reflection and transmission helps to validate models that can be used to estimate sound transport in engines at an early stage of development.
