PDF-(BOOS)-Aircraft Propulsion

Aircraft Propulsion is an engineering textbook written for students in aerospace and mechanical engineering The book covers aircraft gas turbine engine and rocket propulsion from its basic principles to more advanced treatments in engine components Propulsion system integration with aircraft plays an important role in understanding propulsion and is thus addressed in the book Extensive review material and derivations are intended to help students navigate through the subject with more ease Over 100 examples and 300 problems are designed to practice the principles learned in jet propulsion and compliment learning through applications In every engine component issues related to manufacturing material properties temperature limitations and cooling are included to give students an appreciation for the broader scope of propulsion engineering than just aerothermodynamics Component matching and offdesign analysis is detailed in a separate chapter to provide the physical and performance linkage between the components and their impact on aircraft engines Principles of chemical rocket propulsion are presented in the context of singlestage to orbit propulsion needs of a rocketbased combined cycle vehicle The broad treatment of the gas turbine engine cycles and components makes the book suitable as a reference for propulsion and turbomachinery engineers gas turbine industry and professional development courses.

Aerospace propulsion devices embody some of the most advanced technologies, ranging from materials, fluid control, and heat transfer and combustion. In order to maximize the performance, sophisticated testing and computer simulation tools are developed and used.Aerospace Propulsion comprehensively covers the mechanics and thermal-fluid aspects of aerospace propulsion, starting from the fundamental principles, and covering applications to gas-turbine and space propulsion (rocket) systems. It presents modern analytical methods using MATLAB and other advanced software and includes essential elements of both gas-turbine and rocket propulsion systems. Gas turbine coverage includes thermodynamic analysis, turbine components, diffusers, compressors, turbines, nozzles, compressor-turbine matching, combustors and afterburners. Rocket coverage includes chemical rockets, electrical rockets, nuclear and solar sail.Key features:- Both gas-turbine and rocket propulsion covered in a single volume- Presents modern analytical methods and examples- Combines fundamentals and applications, including space applications- Accompanied by a website containing MATLAB examples, problem sets and solutionsAerospace Propulsion is a comprehensive textbook for senior undergraduate graduate and aerospace propulsion courses, and is also an excellent reference for researchers and practicing engineers working in this area. This book is a self-contained introduction to the aerodynamic and thermodynamic design of modern civil and military jet engine design. Through two engine design projects for a large passenger and a new fighter aircraft, the text explains modern engine design. Individual sections cover aircraft requirements, aerodynamics, principles of gas turbines and jet engines, elementary compressible fluid mechanics, bypass ratio selection, scaling and dimensional analysis, turbine and compressor design and characteristics, design optimization, and off-design performance. The civil aircraft, which was the core of the Part 1 of earlier editions, has now been in service for several years as the Airbus A380. Attention in the aircraft industry has now shifted to two-engine aircraft with a greater emphasis on reduction of fuel burn, so the model created for Part 1 is the new efficient aircraft, a twin aimed at high efficiency. A complete investigation of the development and suppression of antigravity and field propulsion technologies • Reveals advanced aerospace technologies capable of controlling gravity that could revolutionize air travel and energy production • Reviews numerous field propulsion devices that have thrust-to-power ratios thousands of times greater than a jet engine • Shows how NASA participates in a cover-up to block adoption of advanced technologies under military development In Secrets of Antigravity Propulsion, physicist Paul LaViolette reveals the secret history of antigravity experimentation--from Nikola Tesla and T. Townsend Brown to the B-2 Advanced Technology Bomber. He discloses the existence of advanced gravity-control technologies, under secret military development for decades, that could revolutionize air travel and energy production. Included among the secret projects he reveals is the research of Project Skyvault to develop an aerospace propulsion system using intense beams of microwave energy similar to that used by the strange crafts seen flying over Area 51.Using subquantum kinetics--the science behind antigravity technology--LaViolette reviews numerous field-propulsion devices and technologies that have thrust-to-power ratios thousands of times greater than that of a jet engine and whose effects are not explained by conventional physics and relativity theory. He then presents controversial evidence about the NASA cover-up in adopting these advanced technologies. He also details ongoing Russian research to duplicate John Searl’s self-propelled levitating disc and shows how the results of the Podkletnov gravity beam experiment could be harnessed to produce an interstellar spacecraft.
