Annual report - National Advisory Committee for Aeronautics
This is an annual report issued by the United States National Advisory Committee for Aeronautics, printed in Washington by the Government Printing Office in 1915 for government, military and aviation readers. Its pages carry technical graphs of airfoil lift and drag, propeller performance curves and charts of aircraft test data. A designer could draw on the clean, dense plotting grids, fine curve families and labelled axes as a source of technical diagram styling.
