Sikorsky Aircraft Completes Active Rotor Wind Tunnel Testing

Noise And Vibration Reduction Through High-Authority Flaps Concept Validated

Helicopters normally make a lot of noise, and a great deal of that noise comes from the movement of the aircraft's' rotors through the air. This week, Sikorsky Innovations said it has completed wind tunnel testing of its active rotor system equipped with high authority flaps. The effort is jointly funded by Sikorsky and the U.S. Army Aviation Applied Technology Directorate (AATD).

"We have validated the concept of properly controlled, high authority flaps to favorably impact external rotor noise, and vibration," added Jim Kagdis, program manager for Sikorsky Advanced Programs. "Our test results show reductions in vibration, rotor hub and controls loading, and a reduced acoustic emission."

"The AATD/Sikorsky Active Rotor Team has accomplished a lofty goal: to demonstrate the functionality of a trailing edge flap and closed loop control system," said Chris VanBuiten, Director of Sikorsky Innovations. "The system performed extremely well over a variety of forward flight conditions up to 140 knots."

Mark Miller, Sikorsky vice president, research & engineering, added: "The completion of this wind tunnel testing provides valuable data to guide future programs such as AATD's Reconfigurable Rotor and DARPA's Mission Adaptable Rotor (MAR) programs. Sikorsky remains committed to the maturation of game-changing technologies such as active control features on helicopter blades to maximize aircraft performance and effectiveness."
