The maximum headway of this unmanned plane reaches 225 miles per hours (about 360,000 ms/h), 6 hours cruising time, the highest flies to 6096 meters. Compared with fixed-wing unmanned plane, " hawkeye " can VTOL, hovering, flexible operation. Compared with depopulated helicopter, " hawkeye " cruising speed is fast, boat duration, flight envelope are big. Obviously, compared to helicopter and fixed-wing, tilting rotor advantage is a lot. Technical problem can but become the key factor hindering its development. These technological difficulties relate generally to the composite of the conversion between helicopter and fixed wing airplane pattern, flight control system, blade and fuselage and the electromotor of aircraft. The V22 osprey tilt rotor aircraft of American R & D just has rotor and fixed-wing simultaneously, it be one can landing, hovering, again can the farther type aircraft of voyage, prospect is very good. But it yet suffers from shortcoming, such as the fixing wing section obstruction to propeller downdraught, aircraft is made to lose the power of about 1/10th in the VTOL stage needing most power.
