摘要

The goal of this study was to characterize the effect of propeller variables as relevant to the design of a flight vehicle with numerous distributed propulsors. The impact of propeller radius, quantity, airfoil section characteristics, and blade count is examined. The test case is a small general aviation aircraft evaluated at a condition corresponding to cruise, such that thrust is constrained and propeller slipstream effects are negligible. From the perspective of power required, a minimal number of large-radius propellers are preferable. Increasing the number of propellers or blade count reduces the individual loading on each blade, which can lead to a significant drop in efficiency if the airfoil characteristics of the blade's section are not well matched to the operating conditions. Reducing propeller radius is associated with a reduction in estimated range and endurance for a battery-powered aircraft.
