The aerodynamic characteristics of a wing-propeller combination with the propeller rotating in the wing-chord plane of a two-dimensional wing were investigated. The wing had a 4-1/2-foot chord length. Total static lift was measured with and without the wing for a 3-foot-diameter propeller; the effects of a ground plane on the static lift of the wing-propeller combination were measured with a 2-foot-diameter propeller. Lift and pressure distributions at several angles of attack and free-stream airspeeds from 0 to 93 feet per second were obtained with the 3j-foot diameter wing-propeller combination.
