Eurocopter Blue Edge rotor blade noise reduction Eurocopter video showing the reduction in rotor noise acheived in flight tests of its Blue Edge blade on an EC155 helicopter. Compared with a conventional blade, the Blue Edge has a tip with both forward and rearward sweep. Eurocopter says this gives the blade more time to interact with the vortex shed by the rotor, reducing the characteristic impulsive (slap-slap) blade-vortex interaction noise generated by a helicopter.
