Aerodynamic and aeroacoustic design of small unmanned aircraft system propellers at low Reynolds numbers.
… sUAS propulsion systems and specifically the propellers, largely responsible for noise generation and inefficiencies in power consumption at low Reynolds numbers. Experimental noise data compared stock, modified, and five bladed propellers reducing tip vortex strength and noise generation. …

Performance and slipstream characteristics of small-scale propellers at low Reynolds numbers
The low Reynolds number effects of small-scale propellers were investigated. At the Reynolds numbers of interest (below 100,000), a decrease in lift and an increase in drag is common making it difficult to predict propeller performance characteristics. A propeller testing apparatus was built to …
