Hysteresis assumptions for propeller in yaw in close stall conditions

Rozehnal D., Nguyen V.B., Hnidka J.
pages 721 - 724, full text

For small unmanned aerial vehicles (UAVs), which typically feature a fixed-pitch propeller, the appropriate selection of the propeller design can lead to increase of thrust and flight efficiency. The current analytical models of propeller display inherent uncertainty, which close to stall conditions is dominated by the dynamic stall phenomenon. The paper presents oscillating airfoil theory and Joukowsky vortex theory, and discusses problems of oscillations close to the stall conditions.
