Nearly Silent Helicopter Blades, Cool!

Posted: March 1, 2010 in Info News

was never a big fan of real helicopters (I do fly two R/C choppers though), but this story caught my eye because I’m big on technology. Helicopter blades generally are very loud because of something called blade-vortex interaction. Eurocopter engineers have developed a new kind of rotor blade that fixes this problem. It’s called Blue Edge, take a listen to how the new blades sounds compared to the ones on copters now.
