Carter Copter Breaks Mu-1 Barrier
tyler_larson writes "Just over a week ago, Jay Carter's CarterCopter managed to break a significant rotorcraft barrier, traveling at a mu ratio of 1. This 1-to-1 ratio (sometimes called the mu-1 barrier) represents a condition where the forward speed of the craft is the same as the speed of the tip of the rotor. This means that at a certain point, the tip of the retreating blade is "standing still" relative to the wind and producing no lift, while the rest of the blade is actually moving backwards through the air. Such a condition is normally impossible for a rotorcraft, and so the forward speed of a helicopter is limited by the the speed of the rotors. This accomplishment by the CarterCopter, which some insisted couldn't be done, proves that this new craft is not subject to that limitation." -

Fabulous Flying Machine Progress
HobbySpacer writes "A SoloTrek video shows a recent tethered hover test of the one person VTOL vehicle.The company has DARPA and NASA support and has carried out a number of sucessful wind tunnel and power tests. Meanwhile, the CarterCopter RotorWing demonstrator may soon show for the first time that a vehicle with a rotor can safely achieve very high airspeeds (e.g.400-500 mph) where the tip speed is actually slower than the vehicle speed. This has been a great project to follow since they are so open and honest about the various problems and fixes during the development. Just wish Moller was as transparent about the Skycar. At least a video and some images were recently posted showing the nose of the craft lifting off under its own power." -
