Excerpt from The Design of Aeroplanes The present volume is the outcome of an endeavour to fulfil an aeronautical need, which must have been experienced by most designers, draughtsmen, and students, in entering the field of aeronautics - namely, the absence of collected data and design methods. In other branches of engineering one finds numerous design and pocket books containing a compendium Of useful information, and fulfilling most of the ordinary requirements. In aeronautical engineering, however, although there are numerous works of a more or less popular and romantic nature, yet the absence of similar design and pocket books is marked, no doubt on account of the more recent development of this branch. The chief Object of the present work is to present in a simple yet brief form the principles underlying the design of aeroplanes from the standpoint of the mechanical engineer, and to collect and tabulate some of the data which experience has shown to be useful in design work. A chapter has been included dealing with the more important mechanical principles involved in aeronautical design, with an indication as to their utility and application. Obviously, the subject Of aeroplane design is now so wide that it is impossible either to treat each branch of the subject in full, or to embrace every branch, but it is hoped in the complete series of aeronautical manuals to cover most of the ground; the author, for these reasons, seeks the indulgence Of the reader for any apparent incompleteness in the present work.
