Active Noise Control Facility (ANCF)


  • Highly configurable 4-foot diameter ducted fan
  • TRL level 2-3 for turbofan engine representation
  • Fan speeds from 100-2400 RPM (corrected)
  • Rotor tip speeds up to 500 ft/sec (150 m/s)
  • Inlet duct Mach numbers up to 0.16
  • Fundamental blade passing frequency of 250 Hz – 2.5 kHz
  • Unique Rotating Rake system. The Rotating Rake provides a complete map of the acoustic duct modes present in a ducted fan
  • Adjustable fan blade pitch
  • Inflow Control Device (ICD) integrated into inlet lip, used for static engine testing to break up ground vortices
  • Variable count stator hub, to test rotor/stator interactions. Stator counts can vary and be set at any angle.
  • Integrates with multiple additional aero-acoustic measurement and/or control capabilities
