Long-standing and important research is conducted in the Alfred Gessow Rotorcraft Center, as a U.S. Army Center of Excellence in Helicopter Technology. One of only three such centers in the country, the center conducts leading-edge research in rotorcraft aerodynamics, dynamics, acoustics, structures and flight mechanics. Unique experimental facilities such as two fully-instrumented rotor rigs, a hover tower and a 10-foot vacuum chamber are funded by the Army and by an industry consortium.
