Pratt and Whitney: Turbulence Control Structure

West Virginia, USA

Turnkey design and supply of a Turbulence Control Structure (TCS) for engine inlet noise measurements and performance testing of turbofan engines.

Key features:

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, which are made of perforated stainless steel sheet bonded to an aluminium honeycomb substrate. The perforated sheet serves to attenuate stream-wise flow unsteadiness, while the honeycomb structure provides transverse flow uniformity.

• 4.2m geodesic dome comprising 241 polygonal frames with flow panels
• 1.4m engine inlet diameter
• Self supporting mobile structure to facilitate towing around an outdoor test site and easy alignment with an engine’s inlet cowling
• Height adjustable
• Designed for ease of assembly, disassembly, and transportation between various Pratt and Whitney sites
• Integrated pressure probes

Capabilities:

• Designed for use with PW545, PW305, PW306, PW308, PW-ATFI, PW6000

MDS scope of work:

• Turbulence control structure
• Integrated transportation cart
• Braking and locking mechanism
• Engine-specific annular sealing cloths
• Portable section reusable shipping containers
