The performance criteria， such as flight speed and voyage， are restricted due to the configuration of conventional helicopter. High speed is one of the important trends in the development of helicopter. Euramerican countries have already invested massive resources in developing high-speed helicopter and obtained phased breakthroughs. In this paper， the essential reasons for the restriction of conventional helicopter flight speed and some different configurations which can improve flight speed are analyzed firstly. Then， detailed analysis is made focusing on the four high-speed configurations with great development potential， i.e.， coaxial-rigid-rotor high-speed helicopter， tilt rotor aircraft， dual thrust compound high-speed helicopter and multi-propeller tilt-rotor high-speed electric-driven helicopter. The special key technologies during the development of different high-speed helicopter， due to the differences in configuration， are analyzed systematically. Also， the technical approaches of these different key technologies are investigated. The difficulties and development direction among them are pointed out as well. Finally， some development strategies of the high-speed helicopter are presented.
