Turbulence Control Structure – Pratt & Whitney Canada, Florida, USA

Project


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 stream-wise flow unsteadiness, while the honeycomb structure provides transverse flow uniformity.

Features

  • 4.2m geodesic dome comprising 241 polygonal frames with flow panels
  • Accommodates up to 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 & Whitney Canada sites
  • Integrated pressure probes

Capabilities

  • Designed for use with PW545, PW305, PW306, PW308, PW-ATFI, PW600

MDS Project Scope
