In this study, rotors space and number of the blade are examined in terms of the torque, power and thrust concept. Three-dimensional flow analysis was performed by using SolidWorks flow simulation. In aircraft propeller design, thrust, torque and power concept has a great deal of importance. The rotor can be defined as a propulsion system, which provides the thrust with a propeller. The pressure difference produces due to the velocity difference between the lower and upper surfaces of the airfoil. The thrust is obtained with this pressure difference. The rotor blades produce drag and thrust thanks to rotating airfoils. The number of the blade affects the amount of thrust directly. If the blade number of rotor increases, the produced thrust, torque by the rotor and the needed power to drive rotor will also increase. In this study, the effect of blade number (2, 3 and 4 blades) and distance between rotors (0.05*D, 0.1*D, 0.25*D, 0.5*D, 0.75*D, 1*D) on the thrust, torque and power are investigated.
