From the Preface: "With the advent of jet-propelled and other high speed airplanes, the power - plant has become increasingly important in all phases of aviation. The need for an up-to-date textbook covering these modern powerplants has been obvious to the authors for some time.

Aircraft Propulsion Powerplants has been written to provide the background which will enable the student maintenance engineer and the aircraft engine mechanic to explore and grasp with greater clarity the facts pertaining to the more involved aspects of the airplane engine and its operation. This book stresses fundamentals and operating principles. It is intended not only to give the reader a foundation in all phases of engine and accessory design, construction, and operation, but also in those systems which are related to the operation of the engine, such as external oiling systems, fuel systems, and electrical systems. No attempt has been made to give detailed information about specific makes and models of engines and engine accessory and related equipment, except where such information can be used to enhance the reader's understanding of the phase of the material under discussion.

The book should be of considerable value to mechanics studying for their C.A.A. aircraft engine mechanics rating, to instructor personnel teaching air-craft engine subjects, to students studying aviation subjects in technical high schools, to students in colleges offering aeronautical and mechanical training, and to aviation personnel in general as a convenient reference manual.

It is the opinion of the authors that engines in commercial aircraft will continue to be of the conventional, reciprocating type for some time to come. However, the turbine-propeller engine and turbojet engines will be used in in-creasing numbers not only in military aircraft, but also in commercial aircraft in the near future. Accordingly, the gas turbine engines have been discussed and explained in this book with the idea of preparing the student for these modern engines."

From the Foreword: "This work meets a long standing need for a text which bridges the gap between the largely practical treatment of the subject on one hand, and the largely theoretical treatment on the other. Thus the book lends itself to teaching not only students having little preparatory background and aiming at vocational training, but also those planning further study in the field.

From the standpoints of scope, coverage, and teachability, it ranks far ahead of anything I have seen. It not only incorporates detailed information on the latest equipment, including jet propulsion, but it also covers the various types of powerplants being used for instructional purposes in most schools today. Every part of the engine and its related equipment has been included.

Each is discussed extensively with particular emphasis on fundamental principles. Possibly its most outstanding attribute is the practical slant in all discussion. Both authors are themselves certificated mechanics, and, having taught thousands of students, are able to anticipate certain questions that inevitably arise in students' minds. Having participated in the stepped-up program for the training of mechanics for the Air Forces during the last war, the authors have been able to emphasize those fundamentals which usually need to be reviewed in order to refresh the students' background.

Even in its technical accuracy, the language is simple and understandable, with more than five hundred illustrations to aid in visualization of the construction, function, and operation of the many component parts of the aircraft powerplant. This text will, I am certain, be welcomed by teachers and students alike as a valuable forward step in training and developing technicians who are able to understand and deal intelligently with all types of powerplants now in use as well as those which will be built in the near future utilizing these basic principles."
