Elementary aeronautics; or, The science and practice of aerial machines
A 1911 technical textbook by Albert Peter Thurston, published in London and New York by Whittaker & Co. for engineering students and early aeroplane builders. Line diagrams show propellers on test rigs, airflow traced as streamlines around blades and planes, and halftone photographs of wing trusses and bracing wires, useful for arrow-flow schematics and skeletal airframe silhouettes.
