Turbulence Control

Our Turbulence Control Structure design (TCS) reduces the level of turbulence in the airflow entering an aircraft engine. We accomplish this by arranging the special flow panels in a dome around the engine inlet, which is 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.

Description

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.
