Abstract : This report presents a summary and an evaluation of the meetings held to review the status of aerodynamic loads prediction for rotorcraft. A broad review of helicopter aerodynamics was accomplished during the meeting. The level of prediction methods and their verification varied throughout the helicopter community. Considerable progress was reported on airfoil development and the description of non-linear airfoil behavior. Large analyses/computer programs appeared to be the most common mode for prediction of loads. It did not seem, however, that fully adequate verification of the predictions was being made. Specific weakness were evident in the verification of the flow models used.
