It is the purpose of this book to enter into the distinctive features of the internal combustion engines used in flight, their construction and the peculiar demands made upon them by flight conditions. These engines are not necessarily confined to use on the aeroplane but are engines equally adapted for use on dirigibles or for other flight apparatus that may be developed in the future. All of the engines described have seen actual service, and by far the greater number of them are what may be described as "Standard" constructions. While the basic principles of the automobile and aeronautic motor are identical, there are very many constructional differences that require individual treatment, and a book dealing exclusively with automobile engines is not in the least of value as a reference work on aeroplane engines. The working conditions of the two engines are entirely different, in fact the requirements of the aeronautic engine more nearly approach those of the marine engine that an automobile engine. The question of weight has again divided aeronautic engines into various sub classes which have no equivalent in either marine or automobile service, the radial and rotary types being prominent examples. Diagrams, illustrations, and line drawings accompany every example for ease of understanding. Chapters: 1. The Aeroplane Engine 2. Gasoline Engine Principles 3. Aeronautic Engine Requirements 4.
