Approximate Calculation of the Static Longitudinal Stability of Airplanes
This is a 1926 NACA technical report on approximating the static longitudinal stability of aircraft, issued by the NASA Technical Reports Server collection for aeronautical engineers and researchers. Its pictures are line diagrams of biplane and monoplane wing sections, angle-of-attack and downwash geometry, and a graph of moment coefficient against angle of attack for wing and tail, offering a designer a clean schematic vocabulary of airfoil profiles and stability curves.
