The Kiln Drying of Wood for Airplanes
A 1919 government technical report on kiln drying wood for aircraft construction, issued under the NASA Technical Reports Server's collection of historical aeronautics papers, most likely written for engineers and aviation manufacturers. Its four pictures show stacked oak timber, magnified microscopic sections of oak grain, and a cross-sectional diagram of a water spray dry kiln with steam jet pipes. A designer could draw on the stacked lumber grid and the cellular tissue patterns for textures, geometric repeats, or scientific diagram styling.
