This file contains a geometrical (CAD) model of Delft University of Technology's TUD-XPROP propeller. This six-bladed, 16”-propeller can be used for the validation of numerical tools because experimental data sets are available (shared separately). A single CAD model is provided that contains a simplified geometry suggested for numerical (CFD) analyses. It includes all components of our isolated propeller test setup. The geometry is constructed from separate components, that can be enabled/disabled by the user. The blades are set to a pitch angle of 30 deg at r/R=0.7. The gap between spinner and nacelle is filled with a separate part in the stp file, and hence can be deselected/hidden in case it is desired to include the gap in the simulation. The CAD files are available upon request and are intended for non-commercial use. When making the request, please include your affiliation and specify for what purpose you would like to use the geometry.
