Customer:Pratt & Whitney CanadaFlorida, USAFacility Type:Turbulence Control Structure, Turbofan PerformanceEngine Types:PW545, PW305, PW306, PW308, PW-ATFI, and PW6000Description:Turnkey design and supply of a Turbulence Control Structure (TCS) for engine inlet noise measurements and performance testing of turbofan engines.A TCS reduces the level of turbulence in the airflow entering an aircraft engine. This is achieved by the special flow panels arranged in a dome around the engine inlet, composed of perforated stainless steel sheet bonded to an aluminum honeycomb substrate. The perforated sheet serves to attenuate streak-wise flow unsteadiness, while the honeycomb structure provides transverse flow uniformity.
