Effect of variation of chord and span of ailerons on hinge moments at several angles of pitch
This is a 1932 NASA technical report, published by NACA-era aeronautical researchers, presenting wind-tunnel test results on aileron hinge moments for aircraft wings. The record gives no further detail, so the pictures are the main guide. The charts are plain line graphs with dashed and solid curves labelled by aileron deflection angle, useful to a designer wanting a clean technical diagram style with simple labelled axes and grid structure.
