UIUC Propeller Database - Volume 3
This webpage compiled by Or Dantsker, UIUC Version 18/20/20
This webpage includes wind tunnel measurements for 40 Aero-Naut CAM carbon fiber folding propellers. 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.

Dantsker, O.D., Caccamo, M., Deters, R.W., and Selig, M.S., "Performance Testing of Aero-Naut CAM Folding Propellers," AIAA Aviation and Aeronautics Forum and Exposition (Aviation 2020), AIAA Paper 2020-2760, Virtual Event, June 2020.
Notes
- Unless otherwise noted, the propeller size is given in inches, e.g. AeroNaut CAM 9x4F is a 9-inch diameter propeller with a pitch of 4 inch/revolution. The diameter was achieved using a 42-mm yoke.
- Coefficients are based on the propeller diameter. All coefficient data is nondimensionalized using the unfolded manufacturer's stated diameter, e.g. for the 9x4F (that uses the 42-mm yoke), 9 inch was used. The 9 inch is the physical diameter between the blade tips when the propeller is unfolded.
- 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.
Explanatory Figures
Components: Aero-Naut CAM carbon folding 13x6.5 propeller, Aero-Naut 42mm Yoke, and Aero-Naut 40mm Turbo Spinner.
Assemblies: (Top) propeller blades mounted to yoke with one screw and locknut per blade; these screws are the pivot points for folding;
(Middle) propeller and yoke mounted to the spinner backplate using the spinner collet; this collet also mounts the assembly to the motor shaft.
(Bottom) complete in flight-state.
Note that the stated size of the propeller is 13", which is achieved using the 42mm yoke; i.e. with the propeller lying flat, the distance between the tips is 13".
Yokes: (top) 42mm and (bottom) 47mm.
Note: the size refers to the distance between the propeller blade mounting screw holes, which are the pivot points that the blades rotate about to fold.
