Measurements of Small-Scale Propellers Operating in the Vortex Ring State
… operating in vertical descent and through the vortex ring state (VRS) was measured. In particular, a total of 26 propellers with varying diameters (9 to 11 in) were tested in the UIUC 2.8 x 4 ft wind tunnel at low Reynolds numbers to measure the propeller thrust over a range of advance ratios …
