George Mason University students Nick Lanuzo and Tim Quann used our RCbenchmark Series 1580 thrust stand to compare the thrust, torque and efficiency of three different 3D-printed propellers. They also studied the vibration and acceleration properties of the propellers.
The propeller size as well as the cross-sectional airfoil and pitch were selected as the design parameters to analyze. The study included 10x5, 10x3 and 8x4 propellers 3D-printed by the students.
After several experiments, "it was determined that the airfoil and pitch have some effect on performance, while the size of the propeller matters much more. "
