A 1925 technical report from the NASA Technical Reports Server, catalogued from a NASA technical library scan with no further publication detail, so its audience and place are not stated. Its two pictures are a force-vector diagram of glide, level and climb angles with thrust and lift vectors, and a plotted curve of flight path angle against indicated airspeed in miles per hour. A designer could borrow the layered vector-diagram structure for showing forces, or the sparse plotted-point line chart style for showing performance data.
