The airta对 government institutions in some countries have focused on the development of the rotorcraft. NASA is funding the development of the rotorcraft Carter Copter,allegedly the maximum level flight speed of which is 804.5 km/h or higher.GBA company recently got the government funding in developing large jet engine type rotor machine.Carter Copter is an aircraft and rotorcraft composite aircraft.Rotor can be simple gearing peroration,with about 27 kg weight on the blade tip,so the rotor in the peroration can reserve more energy for harrier jump after take-off,and allow the rotor still have a good stability in cruise state when at low speed.Cruise flight rotor total distance is reduced,so that the resistance is reduced to be as little as possible,most ofthe lift of which are from fixed wings on the sides. In October 2005,MV-22 osprey project was approved to enter full-rate production, and initial effective in 2007,ending this trial for a period of 18 years.The U.S. defense department official announced that the first five V-22 OSPREY tilt rotorcrafts will be used in the United States Marine Corps.Then the advanced model will be equipped with U.S.Army all around. ●N121CC Figure 1 Carter Copter aircraft 1The air taxi 7 government institutions in some countries have focused on the development of the rotorcraft.
