Wind-tunnel investigation of tapered wings with ordinary ailerons and partial-span split flaps
This is a 1937 NACA technical report from NASA's Technical Reports Server, presenting wind-tunnel test results for tapered wings fitted with ordinary ailerons and partial-span split flaps, written for aeronautical engineers. Its pictures are engineering graphs of rolling-moment and yawing-moment coefficients plotted against aileron deflection in degrees and percent wing semispan, with labelled curves, dashed and solid lines, and grid rulings in black and white, offering a designer little beyond clean line-chart conventions and tidy axis labelling.
