Water Pressure Distribution on a Twin-Float Seaplane
A 1930 NASA technical report on water pressure distribution across the hull floats of a twin-float seaplane, prepared for aeronautical engineers and researchers. The pictures show the aircraft's instrument layout and cockpit, a side view of the floatplane on water, and the pressure-recording apparatus with its accelerometer, mirror and drum recorder; a designer might take from them the crisp black-and-white technical photography and labelled schematic diagram style of early aviation reports.
