UIUC Propeller Database - Volume 2
This webpage compiled by Robert Deters, UIUC
Version 15/27/15
This webpage includes wind tunnel measurements for nearly 70
small-scale propellers. Thirty-five propellers
were purchased off-the-shelf from retail outlets and were
balanced for these tests. The remaining propellers are different configurations
of four propellers that were manufactured using a 3D printer (DA4002, DA4022, DA4052, NR640).
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. The propellers have been digitized (approximately)
and these data are included below.

Notes
- Unless otherwise noted, the propeller size is given in inches,
e.g. APC 9x4 is a 9-inch diameter propeller with a pitch of 4 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 and five 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.
