This book was released on 2004-12 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Operational characteristics of a valveless pulse detonation engine system were characterized by experimental measurements of thrust, fuel flow, and internal gas dynamics. The multi-cycle detonation experiments were performed on an axis-symmetric engine geometry operating on an ethylene/air mixture. The detonation diffraction process from a small initiator combustor to a larger diameter main combustor in a continuous airflow configuration was evaluated during multi-cycle operation of a pulse detonation engine and was found to be very successful at initiating combustion of the secondary fuel/air mixture at high frequencies. The configuration was used to demonstrate the benefit of generating an overdriven detonation condition near the diffraction plane for enhanced transmission of the larger combustor. Results have shown that the addition of optical sensors, such as tunable diode lasers, to provide fuel profile data are invaluable for providing high fidelity performance results. The performance results demonstrated the ability of the valveless pulse detonation engine to run at efficiencies similar to valved pulse detonation engine geometries and may be a low-cost alternative to conventional air-breathing propulsion systems.

Book Synopsis Fundamentals of Aircraft and Rocket Propulsion by : Ahmed F. El-Sayed
Download or read book Fundamentals of Aircraft and Rocket Propulsion written by Ahmed F. El-Sayed and published by Springer. This book was released on 2016-05-25 with total page 1025 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive basics-to-advanced course in an aero-thermal science vital to the design of engines for either type of craft. The text classifies engines powering aircraft and single/multi-stage rockets, and derives performance parameters for both from basic aerodynamics and thermodynamics laws. Each type of engine is analyzed for optimum performance goals, and mission-appropriate engines selection is explained. Fundamentals of Aircraft and Rocket Propulsion provides information about and analyses of: thermodynamic cycles of shaft engines (piston, turboprop, turboshaft and propfan); jet engines (pulsejet, pulse detonation engine, ramjet, scramjet, turbojet and turbofan); chemical and non-chemical rocket engines; conceptual design of modular rocket engines (combustor, nozzle and turbopumps); and conceptual design of different modules of aero-engines in their design and off-design state. Aimed at graduate and final-year undergraduate students, this textbook provides a thorough grounding in the history and classification of both aircraft and rocket engines, important design features of all the engines detailed, and particular consideration of special aircraft such as unmanned aerial and short/vertical takeoff and landing aircraft. End-of-chapter exercises make this a valuable student resource, and the provision of a downloadable solutions manual will be of further benefit for course instructors.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the latest developments in detonation engines for aerospace propulsion, with a focus on the rotating detonation engine (RDE). State-of-the-art research contributions are collected from international leading researchers devoted to the pursuit of controllable detonations for practical detonation propulsion. A system-level design of novel detonation engines, performance analysis, and advanced experimental and numerical methods are covered. In addition, the world’s first successful sled demonstration of a rocket rotating detonation engine system and innovations in the development of a kilohertz pulse detonation engine (PDE) system are reported. Readers will obtain, in a straightforward manner, an understanding of the RDE & PDE design, operation and testing approaches, and further specific integration schemes for diverse applications such as rockets for space propulsion and turbojet/ramjet engines for air-breathing propulsion.

Book Synopsis The Detonation Phenomenon by : John H. S. Lee
Download or read book The Detonation Phenomenon written by John H. S. Lee and published by Cambridge University Press. This book was released on 2008-06-30 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the detonation phenomenon in explosives. It is ideal for engineers and graduate students with a background in thermodynamics and fluid mechanics. The material is mostly qualitative, aiming to illustrate the physical aspects of the phenomenon. Classical idealized theories of detonation waves are presented first. These permit detonation speed, gas properties ahead and behind the detonation wave, and the distribution of fluid properties within the detonation wave itself to be determined. Subsequent chapters describe in detail the real unstable structure of a detonation wave. One-, two-, and three-dimensional computer simulations are presented along with experimental results using various experimental techniques. The important effects of confinement and boundary conditions and their influence on the propagation of a detonation are also discussed. The final chapters cover the various ways detonation waves can be formed and provide a review of the outstanding problems and future directions in detonation research.

Book Synopsis Nonsteady, One-dimensional, Internal, Compressible Flows by : John A. C. Kentfield
Download or read book Nonsteady, One-dimensional, Internal, Compressible Flows written by John A. C. Kentfield and published by . This book was released on 1993 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first text devoted exclusively to the subject of nonsteady, compressible, internal flow theory and the application of this theory to practical devices. The need for such a text has become apparent with the availability of commercial equipment dependent upon this type of flow phenomena. The book is usable both as a text for graduate level courses and as an introduction for readers wishing to become familiar with nonsteady flow phenomena and their practical applications. This audience consists of mechanical, chemical, and aerospace engineers; and specialists in fluid mechanics. The first and second chapters are introductory in nature, aiming to assist readers conversant with the concepts of steady flow to adjust to unfamiliar events and circumstances while avoiding the finer details of algebraic manipulation. A generalized derivation of the classical method-of-characteristics as applied to one-dimensional, nonsteady, internal flows is included in chapter three. Chapter four is devoted to a study of the various boundary conditions necessary for handling a wide range of problems. Chapter five deals with methods of solution including both graphical and numerical procedures. The remaining five chapters explore specific fields of application. These include pipeline flows, dynamic pressure exchangers, pulse combusters and the tuning of the exhaust and induction systems of reciprocating, and Wankel type, internal combustion engines. Additional nonsteady flow devices are described in the last chapter. All the latter chapters are supported by appropriate references to available literature, including the basic material presented in the first half of the book. When necessary, additional specialized theoretical material is included in each of the special-topics applications-oriented chapters. In order to fulfill the needs of graduate students and their instructors, worked examples are included in addition to exercise problems.
Book Synopsis Pulse Reactor Lift-propulsion System Development Program by : Raymond Marshall Lockwood
Download or read book Pulse Reactor Lift-propulsion System Development Program written by Raymond Marshall Lockwood and published by . This book was released on 1963 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pulse Reactor Engine Program is aimed at developing efficient, high performance lift-propulsion systems that have no moving parts. The Pulse Reactor engine is unique in that it rejects foreign particles that are denser than air; therefore, it can operate in the interface between ground and air that is denied to other aircraft lift-propulsion systems. In particular, development has been concerned with the performance effects of (1) engine size, (2) new shapes, (3) forward flight and vertical flight performance, (4) engine controls and accessories, (5) pulse reactor materials, construction techniques and engine durability.
