- Summary:
- Lift and drag comparisons were based upon flap settings that would trim the model with the center of gravity placed as far back as possible without producing instability in the airplane under any conditions of level flight.
- The auxiliary airfoil increased the maximum lift of the model about the same percentage as it increased the drag for high-speed flight over that of the model without the auxiliary airfoil. The lift obtained in the trimmed condition with the auxiliary airfoil compares favorably with that for a conventional airplane.
- The improvement of the model obtained through the application of the auxiliary airfoil in the position tested was not sufficient to justify the necessary complication.
- Wind-tunnel tests were made of a model wing having an aspect ratio of 3, a tapered plan form with a straight trailing edge, and a fixed auxiliary airfoil of constant chord. Trimming moments were obtained through the upward deflection of a full-span, constant chord trailing-edge flap.
