Aeroplane Construction and Operation

Many aeronautical books of a purely descriptive nature have been written for the average man, but as a rule they contain little interest for the more serious student of the subject. Other books of a highly technical and mathematical class have also been published, but their contents are all but unintelligible to anyone but a trained engineer. It is the purpose of the author to compromise between these two extremes, and give only that part of the theory and description that will be of practical use for the builder and flyer. The scope of the subjects covered in this volume has been suggested by the questions asked by students and clients and is the result of many years' correspondence with beginner aviators and amateur aeroplane builders. The author has endeavored to explain the principles of the aeroplane in simple, concise language, starting with the most elementary ideas of flight and finishing with the complete calculations for the surfaces, power, weight, etc. When mathematical operations are necessary they are simple in form, and are accompanied by practical problems worked out numerically, so that a man with even the most elementary mathematical knowledge will have no difficulty in applying the principle to his own work.
