Measurement of profile drag on an airplane in flight by the momentum method. Part II
This is a 1930 technical report from NASA's Technical Reports Server, a series of engineering measurements of airplane profile drag taken in flight by the momentum method. It is aimed at aerodynamicists and test engineers. The pictures are plain line graphs of pressure ratios, drag coefficients and integrals plotted against dimensionless variables, with labelled curves and gridded axes, offering a designer little beyond a sparse diagrammatic rhythm of straight and curved lines on white ground.
