This webpage includes wind tunnel measurements for 17 APC Thin Electric 2-bladed, fixed propellers with diameters of 12 to 21 in with various pitch values. Measurements include thrust and torque coefficient data over a range of advance ratios for specific RPMs. Also measurements were taken in static conditions for a sweep over RPMs.

Notes

Unless otherwise noted, the propeller size is given in inches, e.g. APC 12x6 is a 12-inch diameter propeller with a pitch of 6 inch/revolution.
Coefficients are based on the propeller true diameter, which might differ from the manufacturer's list value. See the geometry plot for diameter value used.
The four digit numbers below in the 'Data' category represent the propeller RPM values of each run.
The power coefficient data below were obtained from the measured torque and rotational speed.
