Additional test data on static longitudinal stability
This is a 1934 aeronautical technical report from the British Aeronautical Research Committee, issued as a NASA Technical Reports Server scan, presenting test data on an aircraft's static longitudinal stability. It is written for engineers and aerodynamicists. The pictures are plotted graphs of lift, moment and elevator angle against airspeed and throttle setting, with a small wing and tail diagram, so a designer might take only the clean line-graph styling, with its labelled axes, dashed and solid curves and sparse grid.
