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.
