Excerpt from Aerodynamics: Constituting the First Volume of a Complete Work on Aerial FlightThe problems that arise in connection with the study of Aerial Flight are so numerous and of so diverse a character that, except for their relation to the title subject, they would scarcely find place in one volume. In the present work an attempt is made, it is believed for the first time, to treat the classification of the phenomena associated withthe study of Flight on a comprehensive and scientific basis, The origin of the present work may be said to date from some experiments carried out in the year 1894. These experiments, which were primarily directed as a test of certain theoretical views which the author then advanced, resulted In the production Of flying models of remarkable stability, whose equilibrium was not destroyed by an ordinary gale of wind.As originally formulated the theory was incomplete and in many ways imperfect, but it has been developed from time to time during the last twelve years to an extent that to-day renders the approximately correct proportioning of an aerodrome1 a matter of straightforward calculation.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1917 edition. Excerpt: ...Aerodynamic Laboratory at Gottingen, and by M. F. Eiffel, in Paris. A few results relating to strut sections are given in Fig. 31a. The graph a a is a plotting from National Physical Laboratory data,2 relating to the section A, 1 Report of the Advisory Committee for Aeronautios, 1912-1913, No. 83. Report of the Advisory Committee for Aeronautios, 1912-1913, p. 111. representing one of the best forms tested, graphs b and c relating to sections B and C as determined by M. Eiffel.1 In Fig. 31a ordinates represent resistance coefficient both in absolute units and in terms of normal plane (the normal plane unit being that of maximum section). In Fig. 316 are shown two strut-sections designed at the Royal Aircraft Factory. These were reported upon by the N.P.L. as giving less resistance for given strength than a number of others submitted. Approximately, strength for strength, Fio. 31a. these gave one-fourth the resistance of struts of circular section.2 The resistance of wires and ropes has been investigated both by the National Physical Laboratory and by Professor Prandtl of Gottingen. The position may be summarized here by saying that the resistance of a rope or stranded cable, at right angles to the direction of motion, is virtually equal to that of its area projected on a normal plane. The resistance of smooth wires is about 20 per cent. less. Both these results only hold good above a certain minimum value of LV, which may be taken at about 1-5; thus at 100 feet 1 "Resistance of the Air and Aviation," p. 184.! Report of the Advisory Committee for Aeronautics, 1911-1912, p. 95. per second, the rule may be taken as applying to cables or wires down to about T3 inch (= 0-015 foot) diameter.1 Another interesting set of determinations,...
