Der Vogelflug als Grundlage der Fliegekunst / Ein Beitrag zur Systematik der Flugtechnik

A systematic, experiment-based analysis of the mechanics of bird flight that synthesizes observations and measurements to explain how lift and air resistance arise and act on wings. The text examines the wing as a lever, the kinematics and energy cost of flapping, and the relationship between visible wing motion and effective aerodynamic speed. It compares flat and cambered wing shapes, cross-sections and contours using rotating-surface and wind measurements, and evaluates wind effects, hovering, gliding and the work required for various flight modes. The treatment concludes with practical calculations and design guidance for constructing flying apparatus, written to be accessible to educated non-specialists as well as practitioners.
