Experimental facilities at the University of Maryland are unique among U.S. universities, include articulated and bearingless rotor rigs, a small-scale high-speed rotor for aeroacoustic investigations, composite fabrication and testing labs, a 3D laser Doppler anemometer, a vacuum chamber, a hover tower, various structural dynamic and smart structures labs, and the Glenn L. Martin (GLM) Wind Tunnel. These facilities were upgraded by the addition of a unique 16'x16'x23' anechoic chamber with recirculation for acoustic testing of rotors in hover with microphone arrays and other supporting equipment.
