Annual report - National Advisory Committee for Aeronautics
This is an annual report of the United States National Advisory Committee for Aeronautics, published in Washington in 1915 by the Government Printing Office for government, military and technical readers. Its pages show dense engineering graphs of aerodynamic coefficients, tabulated wind tunnel data and flight-test traces of a SPAD-VII takeoff and landing, with airspeed, elevator and rudder curves plotted against time. A designer might take from them the sparse grid-and-curve style of early technical diagrams, with clean line plots and labelled axes that work as minimal graphic texture.
