Rotor Spacing and Blade Number Effect on the Thrust, Torque and Power of a Coaxial Rotor

Abstract

In this study, thrust, torque and power concepts are investigated according to different blade number and rotor spacing for coaxial rotors. The computational fluid dynamic (CFD) analysis of three-dimensional (3D) flow over coaxial rotors is used for this investigation. Power and torque concepts are the important parameter for the design of aircraft and airfoil. Thrust is also another critical parameter for the aircraft performance. A rotor is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade. This pressure difference produce a thrust. Each rotor blade is a rotating airfoil, which produces thrust and drag. Thrust parameter is directly proportionate with blade number. If the blade number increase, thrust will increase. If the blade number of rotor increase, the produced torque by 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 is investigated.
