Available in PDF, EPUB and Kindle. Book excerpt: The unsteady flow within wave rotor passages is influenced by the rotor blade, hub, and tip shroud surface profiles. By averaging from hub to shroud and from blade to blade, a reduced set of the governing equations is obtained that is appropriate for design studies and parametric analyses. The application of these equations requires closure models for force integrals and for correlation terms that arise when the density averages of products of the flow field variables are expanded in terms of products of the density-averaged variables. The force integrals and the correlation terms depend on the instantaneous pitchwise and spanwise flow field distributions established by unsteadiness relative to the rotor, flow turning induced by blade, hub, and tip-shroud profiling, and rotation. Two approaches to model the force integrals are described. The influence of relative unsteadiness and flow turning on the correlation terms is discussed by considering the propagation of gas dynamic waves in rotor passages defined by uncambered, staggered blades and by unstaggered, cambered blades.

Book excerpt: The U.S. Army Research Laboratory, NASA Glenn Research Center, and Rolls-Royce Allison are working collaboratively to demonstrate the benefits and viability of a wave-rotor-topped gas turbine engine. The self-cooled wave rotor is predicted to increase the engine overall pressure ratio and peak temperature by 300% and 25 to 30%, respectively, providing substantial improvements in engine efficiency and specific power. Such performance improvements would significantly reduce engine emissions and the fuel logistics trails of armed forces. Progress towards a planned demonstration of a wave-rotor-topped Rolls-Royce Allison model 250 engine has included completion of the preliminary design and layout of the engine, the aerodynamic design of the wave rotor component and prediction of its aerodynamic performance characteristics in on- and off-design operation and during transients, and the aerodynamic design of transition ducts between the wave rotor and the high pressure turbine. The topping cycle increases the burner entry temperature and poses a design challenge to be met in the development of the demonstrator engine.

Available in PDF, EPUB and Kindle. Book excerpt: Explore the latest edition of a leading resource on sustainable aviation, alternative jet fuels, and new propulsion systems The newly revised Third Edition of Aircraft Propulsion delivers a comprehensive update to the successful Second Edition with a renewed focus on the integration of sustainable aviation concepts. The book tackles the impact of aviation on the environment at the engine component level, as well as the role of propulsion system integration on fuel burn. It also discusses combustion emissions, including greenhouse gases, carbon monoxide, unburned hydrocarbons (UHC), and oxides of nitrogen (NOx). Alternative jet fuels, like second generation biofuels and hydrogen, are presented. The distinguished author covers aviation noise from airframe to engine and its impact on community noise in landing and takeoff cycles. The book includes promising new technologies for propulsion and power, like the ultra-high bypass (UHB) turbofan and hybrid-electric and electric propulsion systems. Readers will also benefit from the inclusion of discussions of unsteady propulsion systems in wave-rotor combustion and pulse-detonation engines, as well as: A thorough introduction to the history of the airbreathing jet engine, including innovations in aircraft gas turbine engines, new engine concepts, and new vehicles An exploration of compressible flow with friction and heat, including a brief review of thermodynamics, isentropic process and flow, conservation principles, and Mach numbers A review of engine thrust and performance parameters, including installed thrust, rocket thrust, and modern engine architecture A discussion of gas turbine engine cycle analysis Perfect for aerospace and mechanical engineering students in the United States and overseas, Aircraft Propulsion will also earn a place in the libraries of practicing engineers in the aerospace and green engineering sectors seeking the latest up to date resource on sustainable aviation technologies.

This book was released on 2018-07-17 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the program was to determine a wave rotor demonstrator engine concept using the Allison 250 series engine. The results of the NASA LERC wave rotor effort were used as a basis for the wave rotor design. A wave rotor topped gas turbine engine was identified which incorporates five basic requirements of a successful demonstrator engine. Predicted performance maps of the wave rotor cycle were used along with maps of existing gas turbine hardware in a design point study. The effects of wave rotor topping on the engine cycle and the subsequent need to rematch compressor and turbine sections in the topped engine were addressed. Comparison of performance of the resulting engine is made on the basis of wave rotor topped engine versus an appropriate baseline engine using common shaft compressor hardware. The topped engine design clearly demonstrates an impressive improvement in shaft horsepower (+11.4%) and SFC (-22%). Off design part power engine performance for the wave rotor topped engine was similarly improved including that at engine idle conditions. Operation of the engine at off design was closely examined with wave rotor operation at less than design burner outlet temperatures and rotor speeds. Challenges identified in the development of a demonstrator engine are discussed. A preliminary design was made of the demonstrator engine including wave rotor to engine transition ducts. Program cost and schedule for a wave rotor demonstrator engine fabrication and test program were developed. Snyder, Philip H. Glenn Research Center...

Available in PDF, EPUB and Kindle. Book excerpt: Written by an author who has devoted the past twenty-five years ofhis life to studying and designing shock wave engines, this uniquebook offers comprehensive coverage of the theory and practice ofshock wave engine design. The only book treating the completepreliminary design of shock wave engines, it provides engineerswith practical step-by-step guidelines applicable to the design andconstruction of small, light- weight, low-powered industrialturbines as well as high performance jet aircraft engines. In his discussions of the advantages and disadvantages of shockwave versus other types of combustion engines, Dr. Weberdemonstrates how and why shock wave engines can be made to workmore efficiently than conventional gas turbines. Among otherthings, he shows quantitatively why combustion temperatures can besignificantly higher in shock wave engines than conventional gasturbines. He evaluates temperatures of moving parts in terms ofcombustion and engine inlet temperatures, and explores the effectof shock coalescence, expansion fan reflections and intersectionson port sizes and locations. And throughout, real and imaginedperformance problems are posed and proven solutions given for shockwave engines--alone and in conjunction with conventional gasturbines or reciprocating internal combustion engines. Designed to function as a practical guide, Shock Wave Engine Designoffers concise step-by-step design techniques in a readily usableformat. Engineers will find precise, detailed directions on suchessentials as how to size wave rotor blade lengths and heights andthe correct rotor diameter for a specified power, and materialselection for rotor and stator. And one entire chapter (Chapter 12)is devoted exclusively to a detailed example design for a 500 hpengine. An authoritative, highly practical guide to state-of-the-art shockwave engine design, this book is an important resource formechanical and aerospace engineers who design aircraft engines orvirtually any type of turbomachinery.
