Project Summary
The purpose of this project was to determine if multiple rotors would increase the torque of a horizontal axis windmill. Torque is the force created by a rotating shaft and is measured in Newton-Meters. Since mechanical power (watts) is the product of torque and rotational speed, revolutions per minute (RPM) were also measured.
Multiple rotors produced more torque and mechanical power at every fan speed tested. The best rotor variation produced more than double the torque and mechanical power at medium and high fan speeds.
