The Advancing Blade Concept (ABC) is a relatively new type of helicopter rotor system that has been flight tested 67 hours. Flight results in a basic helicopter configuration have confirmed several important advantages of the concept and have identified some shorcomings. The background and current status of the program are presented in this paper. Rotor and test aircraft features are briefly described. Flight-test data are compared with similar data from other helicopter flight tests. A qualitative assessment based upon 2 hours of US Government flying is presented. It is noted that this concept is feasible and Army contract objectives have been satisfied. It is concluded that rotor and control system weight fractions must be reduced to achieve the full potential of this concept. This would involve design and development of a lighter weight rotor system utilizing high-modulus material and redesign of the control system. (DePo)
