Sikorsky begins testing of Active Rotor System
As part of an effort to improve helicopter performance, Sikorsky has begun whirl testing a demonstration rotor system with active flaps.
"We have reached full speed of 450 rpm and commenced testing flap integrity and functionality," said Jim Kagdis, program manager for Sikorsky Advanced Programs. "Now we will investigate rotor reconfiguration capabilities to demonstrate the potential to reduce rotor vibration and noise, and increase blade loading, which enables higher maneuverability and speed."
Testing is expected to continue through the month of August. Wind tunnel testing at the National Aeronautics and Space Administration is planned in 2010. The effort is jointly funded by Sikorsky and the Aviation Applied Technology Directorate (AATD). Development partners on the project are United Technologies Research Center (UTRC) for the blades and Hamilton Sundstrand Claverham for the flap actuators.
