Sikorsky Tests Active Rotor; DARPA Kicks Off Adaptive Rotor Effort

Sikorsky is whirl testing a helicopter rotor system with active blade flaps as the Pentagon’s research arm prepares to launch a program to flight-demonstrate an adaptive rotor offering dramatic improvements in performance, noise and vibration.

The active flaps are being tested on a Schweizer S-434 four-blade rotor mounted on a whirl stand simulating hover flight. Wind tunnel tests simulating forward flight are planned for mid-2010 in the 40 x 80-foot tunnel at NASA’s Ames Research Center in California, says Jim Kagdis, Sikorsky’s advanced programs manager.
