Document Type: Book (Technical Reference). Purpose: Informational. Authority: Author Expertise.

Scope: Technical monograph written for a knowledgable audience by Dr. Sanford A. Moss ("Consulting Engineer, General Electric Co."), a foremost expert on aeroplane engine superchargers.

From the Foreword: "Supercharging has such an important place with the modern internal combustion engine that the publication of the present book seems most timely. The material originally appeared in the weekly numbers of the aviation publication Aeronautics, issued under the auspices of the present publishers in 1941, but the author has considerably revised and extended this matter for the present book.

As the author states in Chapter 1, the book is written "not from the point of view of a designer, with a lot of mathematics, but for the benefit of those who are interested in superchargers in a general way, and want to know their how and why, and their historical background."

The publishers consider themselves very fortunate in being able to arrange with such a distinguished authority as Dr. Sanford A. Moss for the publication of this material. He has been a prolific author of scientific and engineering publications for forty years, and is particularly qualified in the present case. The development of the supercharger in the United States has been due to the cooperation of the Army Air Forces, the National Advisory Committee for Aeronautics, the engineers of the various airplane and engine companies, and the experts of the General Electric Company. But Dr. Moss has played a leading part in the development so that he writes from first hand knowledge of his subject.

The whole career of Dr. Moss has been a training for his achievement of the combination of rotary air compressor and turbine wheel driven by combustion gases which is known as the turbosupercharger. As a boy he was machinist apprentice in a shop making compressed air machinery, and later he was draftsman and engineer on several types of internal combustion engines. Interspersed with this work were periods as student, graduate student, and instructor at the University of California and Cornell University with specialization in internal combustion engines and turbine machinery."
