Prediction of the rotor blade performance is important for determining design factors such as weight and size in development of a small-scale helicopter. Generally, prediction of helicopter performance means the estimation of the power required for a given flight condition. However, due to lack of test data and analyzed results for small-scale rotor blade (Re ? 3×10?) this is not an easy task. As an initial research, this work performed a modeling of a single rotor configuration with FLlGHTLAB, a representative commercial comprehensive helicopter simulation tool. Where the experimental data of the induced power factor and the average profile drag coefficients of the blades from rotor test stand was used. Rotor test stand was constructed to investigate aerodynamic characteristics of small rotors, for the test bed operation, the thrust and torque were measured with varying collective pitch angle and fixed RPM. An extra emphasis of the work was on the correction effort that applies experimental aerodynamic data to the existing airfoil data improving reliability of the simulation. In this process, we performed small-scale isolated single rotor by experimental and numerical method and achieved good agreement of the hover performance on the test data and simulation results.
