This paper describes the survey results on major high speed rotorcraft development programs such as Sikorsky X2, Eurocopter X3, DARPA(Defense Advanced Research Project Agency)-Boeing DiscRotor, and Russian AHSH(Advanced High Speed Helicopter). Each development program is investigated especially in viewpoints of program status and technical achievement. And some technical issues are surveyed to develop a high speed rotorcraft without any penalty in VTOL(Vertical Takeoff or Landing) and hovering attributes.
