Wind tunnel research comparing lateral control devices, particularly at high angles of attack X : various control devices on a wing with a fixed auxiliary airfoil
A 1933 NASA technical report, issued as a numbered NACA technical report, presenting wind tunnel research on wing lateral control devices for engineers and aeronautical researchers. The pictures are plain line drawings of wing cross-sections with spoiler and fixture callouts, plus a dense lift, drag and pressure-centre graph, offering a designer little beyond the technical diagram style of mid-century engineering documentation.
