Rotor/Fuselage Interaction remains as an important problem for engineers and scientists working on helicopter aerodynamics. A model rotor test stand (JAXA Multi-purpose Rotor Test Stand, JMRTS) is used to build an experimental database for CFD code validations. Four blades are connected to an articulated rotor hub. Feathering, flapping and lead-lag angles at the hinges are measured using Hall-sensors which give high accuracy. Miniature Kulite pressure sensors are installed on the cowling surface which simulate a type of helicopter fuselages. Time-averaged and ensemble-averaged periodic data are obtained. Good correlations were obtained in the measured results between the blade angles and six-component forces and moments as well as the pressure fluctuations on the fuselage and blade surfaces. Datasets of several selected test cases are presented together with geometric descriptions of the blade and the fuselage to enable CFD validations by other parties.
