Aerodynamics of lifting surfaces in propeller slipstreams
The high-speed flow in the wake of the propeller also known as propeller wash, or simply propwash, can severely affect the aerodynamic forces on a lifting surface. Steady-state computational results for a symmetric SD8020 airfoil with chord length of 1 ft in a propeller slipstream at a freestream …

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 …

An Experimental Investigation of Blown-Flap Airfoils
… both the performance and flow characteristics of propeller blown-flap airfoils. These surveys produced accurate estimates for the cₗ,cₓ,cₘ performance of these wings as a function of the test parameters of angle of attack, 𝛼, flap deflection, 𝛿 subscript f, and blowing power, Δcj. In proper …
