The CarterCopter is an experimental compound autogyro developed by Carter Aviation Technologies in the United States to demonstrate slowed rotor technology. On 17 June 2005, the CarterCopter became the first rotorcraft to achieve mu-1 (μ=1), an equal ratio of airspeed to rotor tip speed,〔(Significance of μ-1 and the Technical Issues Involved ), ''Carter Aviation Technologies''.〕 but crashed on the next flight〔 and has been inoperable since.〔(Carter CarterCopter CC1 (United States), Aircraft - Rotary-wing - Civil ) ''Jane's all the world's aircraft'', 28 June 2007. Retrieved: 19 February 2012.〕 It is being replaced by the Carter Personal Air Vehicle. ==Design and development== The CarterCopter is a pusher configuration autogyro with wings and a twin boom tail, intended as a prototype and a technology demonstrator.〔(CarterCopter Technology Demonstrator )〕 The rotor is a two-bladed design weighted with depleted uranium at each tip, and it is mounted on a tilting mast, allowing the wing to stay at optimum wing efficiency at all speeds.〔 It is an all-composite design〔(''Flight International 10 - 16 April 2001 General Aviation p28 )〕 with a hull pressurized up to 0.69 bar. The tricycle undercarriage is retractable, and has a large travel to allow for landing at up to 20 ft/sec without bounce. The aircraft had been modified and rebuilt after an accident (a gear-up landing) in 2003.〔O'Brien, Kevin "Hognose". (CarterCopter Advances Towards Mu>1.0 (Part 1) ) ((Part 2) ) ''Aero-News'', April 2004. Accessed: 6 September 2011.〕 NASA had funded $1 million of the development using three research grants, and the aircraft managed to accomplish at least one of NASA's five goals.〔Howard, Scripps.
