Abstract JAXA is proposing a concept of a high speed EMS compound helicopter with the maximum cruise speed 500 km/h which is twice as fast as conventional helicopters. In order to realize this high speed within an envelope of the existing propulsion system, it is essential to develop a very low drag airframe. Furthermore, the compound helicopter has several rotor/propellers and lifting surfaces in the vicinity, which may cause the aerodynamic interference problems. This paper describes the review to the mechanism of the high drag of helicopter airframe followed by the resolution proposals for the airframe with the low drag and the less severe aerodynamic interference.
