(Washington, DC: National Advisory Committee for Aeronautics, June 13, 1925). Two volumes: 28 [introduction, rectos only], (approximately 500) pp.; (approximately 400) pp. Both volumes illustrated with numerous charts, tables, blueprints, diagrammatic sketches and drawings, many folding, volume two with 13 full-size photographs bound-in. The committee members included Goldmark as chairman, William Hovgaard, L.B. Tuckerman, Max m. Munk, and W. Watter Pagon as secretary; this is Pagon's copy, with his ownership signature on the front endpaper of each volume. All five members of the committee signed the introduction on the last page. The committee was charged with reporting on "the design of the semirigid airship RS-1, now being built by the Goodyear Tire & Rubber Company for the Air Service, U.S. Army." Special design and safety problems were studied by various members of the committee, and the results printed here in letters and individual reports. Included in volume two are three pamphlets: (1) The Aerodynamic Forces of Airship Hulls, by Max M. Munk (Washington, DC: GPO, 1924; 20 pp., Report No. 84 of the National Advisory Committee for Aeronautics; OCLC locates Ohio State and a copy in the Netherlands); (2) Water Tests for Semirigid Airships, by LB. Tuckerman (Washington, DC: GPO, 1925; 14 pp., Report No. 211 of the National Committee for Aeronautics; OCLC locates Ohio State and a copy in Germany); and (3) Inertia Factors of Ellipsoids for Use in Airship Design, by L.B. Tuckerman (Washington, DC: GPO, 1925; 7 pp., Report No. 210 of the National Advisory Committee for Aeronautics; OCLC locates a copy in Germany). Laid in is a fourth publication Full Scale Tests of the Semirigid Airship RS-1, prepared by Lt. Robert E. Robillard and Roy A. Miller (Washington, DC: GPO, 1929; 51 pp., Vol. VII, No. 619, Air Corps Information Circular; OCLC locates Washington and Wisconsin Historical Society). Very good. Contemporary blue three-quarter calf (spines and corners scuffed and bumped, joints show wear) and cloth, gilt spine titles. (7183). Item #59436
The RS-1 was the first American built semi-rigid airship, measuring 300 feet in length, 71 feet in diameter, and with a capacity of 700,000 cubic feet. The committe members each brought an area of engineering or aeronautical expertise to their study of the airship: Dr. Henry Goldmark was a well-known consulting engineer in New York, who had designed the great steel lock gates of the Panama Canal; Prof. William Hovgaard of Boston, was director of warship design at MIT, and internationally recognized as the foremost authority on the structural strength of ships; Dr. L.B. Tuckerman, a physicist at the Bureau of Standards; Dr. Max Munk, an aeronautical expert at the National Advisory Committee For Aeronautics; and Prof. Pagon, a member of the Civil Engineering Department at Johns Hopkins University in Baltimore. The RS-1 was in service during the late 1920's but the use of dirigibles for military purposes fell out of favor, and design problems with the nose cap on the RS-1 hastened its end.
