From the Preface; "The fourth edition of a technical monograph written for an educated audience by G. Geoffrey Smith, M.B.E., editor of Flight magazine, the leadin "The essential objective of this book is to present a thorough and fundamental treatment of the thermodynamic principles, the elements of design, and the general construction features of the gas turbine. With this approach, the gas turbine becomes a power plant type which, through modification in design and construction, can be applied to various classes of service. Fundamentally there is no difference in principle between a stationary gas turbine and the power section of a jet engine.

In order to avoid duplication of treatment and at the same time give adequate coverage to the gas turbine field, the organization of the material is by topic or function rather than by type of plant. Thus the full discussion of a particular engine type will not be found under a single heading. For example, the special subject of jet propulsion is treated under several sectional headings throughout the book.

While aircraft gas turbine engines have not been selected for special or individual study, the distinguishing characteristics of these, together with other major types or applications of the gas turbine plant, have been emphasized under pertinent subject divisions. In every case an attempt has been made to refer to the most recent developments in the field through illustrations or design and operating data.

Sufficient theory of design is included to familiarize the student with the general principles that are employed in the field. Although students using this book are expected to have completed a course in the elements of engineering thermodynamics, a chapter covering the principles of this basic subject is included for review. Treatment of aerodynamics and gas flow has been minimized in favor of additional descriptive material to give the student a better idea of the construction and arrangement of gas turbine plants. Operating data are also included to indicate current performance. Because of their increasing use, special emphasis has been placed on the axial-flow compressor and turbine.

Examples are extensively used to illustrate all significant calculations, and problems for student solution are also included. Diagrams are used to supplement the text whenever such sketches are a means of clarification.

Although it is possible to cover this text in a one-semester course, it is believed that there is a sufficient amount of basic material available for a second-semester design course at the senior or graduate level."
