"How I Make Wood Propellers" by Al Schubert, Part 1 Part 2 Simplified Wing Stress Analysis (10Mb PDF) I Beam Analysis Good article on built up spars vs. solid wood spars. (2.5Mb PDF) Strength of Metal Aircraft Elements (8.2mb PDF) Army-Navy Aeronautical Specification, Spruce 1942, reprinted 1950. MIL-S-6073 (0.5Mb PDF) ANC-18 Design of Wood Aircraft Structures. It is split into 3 parts for easy download. I think this might be the first edition, for what it's worth my second edition is dated June 1951.
I don't have the complete ANC-19 in PDF but here are some information from ANC-19 concerning "Requirements for Wood in Specific Parts". ANC-19 pg 118-126 (9.5mb) Three PDF documents that can be used to determine the size and location of the large registration numbers on wings.
