Kinetographic determination of airplane flight characteristics
A 1927 technical report from the NASA Technical Reports Server, a scientific paper on determining airplane flight characteristics by kinetographic methods, prepared for aeronautical engineers and researchers. The pictures are plain line diagrams and a photograph: a geometric figure of a flight path with labelled points, a triangular construction with lettered segments, a graph of curved traces crossing at a point, and a photograph of a camera-like instrument with labelled parts, suggesting technical reference imagery with clean line work a designer could borrow for schematic or instructional graphics.
