A Semi-Quantitative Comparison of Wooden Warships
David Brown provides the reader with a wealth of insight on the workings of wooden ships. He emphasizes wooden warships. An extensive bibliography is provided for further reading.

Brown focuses on the works of Sir Robert Seppings, an early 19th century shipwright who wrote about the deficiencies of wooden shipbuilding. This eventually led to the use of diagonal planking. In an appendix, Brown compares wooden and iron ships: "In a wooden ship, it was the distortion of the sides of the hull which was the major problem. Seppings' analogy of a five-bar gate without the diagonal bar is a good one. Resistance to this change of shape came from friction between the planks which, up to a point, could be increased by hard caulking. Seppings' diagonal trusses were a great improvement but the rows of gun ports still weakened the side structure." (p. 204). Owing to the working of planking, it was impossible to incorporate effective watertight bulkheads (p. 74).

The labor requirements (man-days) for wooden ship construction are provided (p. 170). Brown also gives us statistics on various wooden ships (length, beam, draught, depths, armament, armor, speed, length/beam ratio, mid-section coefficient, prismatic coefficient, etc.) He also includes a graph of bare-hull weight as a function of the ship's dimensions and type (pp. 194-195). The reader may be amazed about how much wood went into wooden ships!

Product Description
When Francis Bacon wrote the New Atlantis in the early 17th century, he envisioned a state-supported research institution in which knowledge could be applied to 'enlarge the bounds of Human Empire, to the effecting of all things possible." Among the research facilities to increase the protection and material comforts of the inhabitants of his imaginary island, Bacon imagined an Engine House to study all types of motion, including flight. National aeronautical research laboratories in Europe and the United States in the early 20th century reflected Bacon's vision of science applied to the practical problems of flight. Commitment to innovation accompanied Bacon's belief in progress. His utopia honored inventors, not politicians or academics.In 1941 the same commitment to innovation and industrial progress won federal funding for a laboratory in Cleveland, Ohio. Local and national leaders expected the new laboratory to promote innovations in aircraft engine technology to help win the war against Germany. Contributions to the development of superior engines for military and passenger aircraft after World War II justified the large federal investment in research facilities and personnel. Today this laboratory is the NASA Lewis Research Center. In contrast to the isolation of the ideal research institution of Bacon's vision, Lewis took shape in a flesh-and-blood world of personalities, national security concerns, and postwar capitalism.Two transitions, both precipitated by advances in propulsion technology, provide the structure for my history: the revolution in jet propulsion during World War II, and the launch of Sputnik in October 1957. Each had significant national political, military, and economic repercussions. Each forced the laboratory to restructure its research program and to redefine its relationships with its three constituencies--the military, industry, and academia. Within this framework I have distinguished one theme that recurs throughout the laboratory's history--the tension between fundamental or basic research and development. In the process of writing my history I found that these terms could not be defined in any absolute sense. Their meaning is enmeshed in the history of Lewis, and the definitions of research and development changed as Lewis evolved. As an institution, Lewis engaged in a continuing reevaluation of its role within the American propulsion community and, after the formation of NASA in 1958, within a vastly expanded federal bureaucracy. ...

Product Description
On the demand side, exporters and strategic planners approaching the market in Africa face a number of questions. Which countries are supplying diesel or semi-diesel compression-ignition engines for marine propulsion to Africa? What is the dollar value of these imports? How much do the imports of diesel or semi-diesel compression-ignition engines for marine propulsion vary from one country to another in Africa? Do exporters serving the market in Africa have similar market shares across the importing countries? On the supply side, Africa also sells to the international market of diesel or semi-diesel compression-ignition engines for marine propulsion. Which countries in Africa supply the most exports of diesel or semi-diesel compression-ignition engines for marine propulsion? Which countries are buying their exports? What is the value of these exports and which countries are the largest buyers? This report was created for strategic planners, international marketing executives and import/export managers who are concerned with the market for diesel or semi-diesel compression-ignition engines for marine propulsion in Africa. With the globalization of this market, managers can no longer be contented with a local view. Nor can managers be contented with out-of-date statistics that appear several years after the fact. I have developed a methodology, based on macroeconomic and trade models, to estimate the market for diesel or semi-diesel compression-ignition engines for marine propulsion for those countries serving Africa via exports or supplying from Africa via imports. We do so for the current year based on a variety of key historical indicators and econometric models. ... Read more

History and Technology of Jets
The technology and the history-of-the-technology of jets from the mid 1930's to 1948. Scholarly, technical, historical, and a bit out of breath in tone.

This is a book very much of its time -- published in 1948, an era of victory, certainly, but also one of unease. With the United States aware of the fact that it did not lead in the application of jet airplanes during WWII, the authors look back at the accomplishments of the Germans and the British while looking forward in the hopes that the United States can dominate this new phase of aviation. This is not propaganda, but it does have a gung-ho optimism and an interest in the affairs of American corporations that are typical of America in the post-war period.

While this book is loaded with information about the nuts and bolts of aviation, it is not designed to simply be an engineering manual.

Details: cloth over hardback boards on glossy paper, 232 pp, about 50 black and white illustrations: photographs, schematics, charts, technical drawings, portraits. 2 over-sized foldout illustrations: Cross-Section drawing of a Junkers Jumo-004 Turbojet and a cross-section of a BMW-003.
