Effect of stabilizer location upon pitching and yawing moments in spins as shown by tests with the spinning balance
This is a 1933 NASA technical report, published in the United States by the National Advisory Committee for Aeronautics, for aeronautical engineers studying aircraft spin behaviour. The pictures are plain engineering line graphs with grid lines, labelled curves and markers for stabilizer positions plotted against angle of attack at centre of gravity, offering a designer little beyond the chart format itself.
