Investigation of the variations in the velocity of the air flow about a wing profile
A 1930 NASA technical report, issued through the NASA Technical Reports Server, presenting engineering research on airflow around aircraft wing profiles for aeronautical engineers. Its pictures are a page of numbered technical plots: a circular diagram, curved streamline families, a wing section with flow lines, and sharp-tipped curve graphs drawn in fine black line on cream paper, offering a designer a clean model of scientific diagram layout and fine-line graphic structure.
