We are on the verge of a new revolution in aerospace and Advanced Rockets Corporation will remain at the forefront of innovation with its ground-breaking technology. Explore Leading the Way Our mission is to make space more accessible than ever before and, through our radical new propulsion system LEAPS and launch vehicle DELV , we will propel the aerospace industry into the future. Our design approach focused on rethinking the role of time-tested, tried-and-true technology for use within a cutting-edge system which is reliant on new, innovative solutions. We implement legacy technology into our cutting-edge technology to enable a practical path to market in the shortest possible time with the fewest hurdles. Ironically, it is this down to earth approach that will enable us to reach the heavens like.

Bertin, resulted from a series of discussions among faculty members of the Department of Aeronautics at the United States Air Force Academy in Upon completion of its orbital mission, the vehicle would re-enter the atmosphere and operate as an airplane during descent and landing on a runway. The single-stage-to-orbit concept envisioned in the NASP has, and will continue to require, the best efforts and intellectual talents the nation has available to make it a reality.

The advent of the NASP program was not the only factor that led to these volumes. The need for a modern treatment of hypersonic aerothermodynamics and airbreathing propulsion analysis and design principles for the academic, industrial and government communities was clear. We sincerely hope that these volumes will serve as up-to-date sources of information and insight for the many students, engineers, and program managers involved in the exciting study and application of hypersonic flight in the years ahead.

Hypersonic Airbreathing Propulsion is intended to provide a broad and basic introduction to the elements needed to work in that field as it develops and grows. It is, to the best of our knowledge, the first fundamental, comprehensive, integrated treatment of the subject. Hypersonic airbreathing propulsion can seem mysterious and forbidding at first because it deals with a regime of flight that lies far beyond ordinary experience and intuition.

Indeed, many unfamiliar phenomena, such as chemical dissociation and supersonic mixing and combustion, are involved. Nevertheless, there are special rewards ahead because hypersonic alrbreathing propulsion is subject to the usual laws of nature, and the desired results can be obtained once those laws are correctly applied to the situation at hand.

The results are often even more appealing and easily understood than their subsonic or supersonic counterparts. The journey through this textbook will therefore only reaffirm and extend your understanding and appreciation of the basics. We believe strongly that upper level engineering textbooks should empower the reader or student to actually do things they could not do before. To that end, you will find this textbook to be almost entirely self-contained.

For one thing, almost every example analytical result presented here can be reproduced using the tools provided. For another, homework problems that develop and stretch understanding are furnished for almost every individual subject. These codes are, in fact, so general that they have application far beyond the bounds of this textbook.

A special issue of hypersonic airbreathing propulsion is that most experimental data are classified for either military or proprietary reasons and are therefore scarce.

We have tried to compensate for this by squeezing the most out of the open literature and tailoring our approach so that future revelations are easily incorporated. Hypersonic Airbreathing Propulsion was written primarily for use in both undergraduate and graduate courses in airbreathing propulsion. Oates will find the flow of our development quite similar to his. This was not our initial concept but an evolutionary outcome that was probably inevitable because the technical content and intended audiences have much in common, vii and because of the undisputed success of his approach.

This has, in fact, been a voyage of discovery for us and, as a result, even the most experienced workers will find original and useful material throughout. In addition to the customary material of Chap. Chapter 1 contains general background, including brief and pointed summaries of the history of hypersonic airbreathing flight and the current situation.

Chapter 3 contains a complete development of the analysis of hypersonic aerospace vehicles, with special emphasis on the contribution of the airbreathing propulsion system to achieving success. Chapter 8 contains information and methods for the estimation of the performance of many types of hypersonic airbreathing propulsion systems. Chapter 9 contains a wide range of topics of special interest to the design and development of ramjet and scramjet engines.

Students taking courses based on this material should have completed at least compressible fluid mechanics and thermodynamics. It is preferable that they have also taken boundary layer theory, equilibrium chemistry, heat transfer, and mechanics and strength of materials. It would be ideal if they have also studied combustion reactions and aircraft or jet propulsion. There is enough material here to occupy a full academic year. However, the topics are sufficiently independent that a suitable selection can be made for an academic quarter or semester.

The treatment, in fact, invites the use of specific topics for individual study, as well as for the insertion of subjects of special interest to the instructor. Heiser, and Dauiel H. Daley, it was sponsored by the U. Air Force and written and field-tested on cadets at the U. Air Force Academy. No work of this magnitude is completed without large amounts and many kinds of help.

The most important are presented next. Robert R. Bart Barthelemy and Chief Scientist Dr. Keith Richey, respectively. Additional vital support and hospitality were furnished by the Department of Aeronautics of the U.

Air Force Academy, arranged primarily by Col. Michael L. Smith, Department Head, and Lt. Thomas R. The textbook benefited greatly from periodic meetings with a formal evaluation committee chaired by Dr. The propulsion reviewers were Dr. Edward T. Edward S. We are indebted to them not only for their conscientious committee work, but for their sincere personal interest and active participation in the project from beginning to end.

Brig Gen Ret Daniel H. Daley, former Head of the Department of Aeronautics of the USAF Academy and incomparable authority on thermodynamics, propulsion, teaching, writing, and, now, basic physical constants and systems of units, patiently read every word, offered innumerable constructive suggestions, artd improved everything he touched.
