UIUC Propeller Database
John Brandt, Robert Deters, Gavin Ananda, and Michael Selig
This webpage includes wind tunnel measurements for propellers used
on small UAVs and model aircraft.
The propeller database includes two volumes:
- Volume 1 - UIUC MS
thesis by John Brandt and following tests
(2005-2008). Refs 1 and 2. Last updated 2/3/15
- Volume 2 - UIUC PhD
dissertation by Robert Deters and following tests (2009-2015).
Refs 3 and 4.
Last updated 5/27/15 (ver 1).
The UIUC data use the standard definitions for propeller aerodynamic coefficients:

Propeller Measurements Comparison - UIUC and Ohio State University
The figures below show a comparison
between UIUC Volume 1 (V3)
data and measurements taken at Ohio State (Ref 5). The results show good
agreement, especially considering that the thrust and torque
measurement techniques differ. For the UIUC data, the thrust is
measured directly with a load cell attached to a pivot arm. The
torque is measured through a torque cell attached to the fixture that
holds the motor. For the OSU data, the measurements were taken using
a multi-axis load cell attached directly to the motor (Ref 6).
APC 10x5E and 10x7E "thin electric" propellers.
