In this study, a low Reynolds flow around a blade is studied by experimental and numerical methods and characteristic curves are extracted. In the experimental static test, the results of thrust force, engine power, current and voltage in different speed for a rotor were recorded. Considering the importance of the flow field around the blade, the static and dynamic numerical simulations of the flow through a blade of Quadrotor are investigated. In addition to the blade aerodynamic results, the statistical of the computational domain are also analyzed. For the numerical simulation, a commercial software (Fluent) is used with the assumption of compressible viscous flow and turbulence model simulations. In this study, the characteristic curves of the rotor blade are extracted by the two mentioned methods. Comparison of numerical and experimental results show good agreement and confirm the accuracy of the measurement. According to the simulation of the flow field around the blade using the numerical method, the effective distance of the blades in order to find the optimum Quadrotor structure is studied.
