Results of extended tests of the Focke-Wulf F 19a "ente," a tail-first airplane
This is a 1933 NASA Technical Reports Server record of extended flight tests on the Focke-Wulf F 19a Ente, a tail-first aircraft, presented as a technical memorandum of engineering data rather than a book for general readers. The pictures are plotted graphs of climbing speed and elevator deflection, line drawings of the wing and tail with control forces labelled, and a three-view style sketch of the airframe with its propeller axis marked. A designer might take from them the clean, sparse plotting style and the labelled schematic conventions used in early aeronautical reports.
