Book excerpt: The objective of this study was to develop and/or improve correlations of fuel properties and engine design with combustion performance and hot section durability. The data base consisted primarily of fuel effect data obtained over the past four years under a number of DoD contracts. The approach taken was first to develop fuel effect correlations for specific combustor configurations, then to tie together these correlations using engine design parameters thereby allowing prediction of fuel effects in any current or future aircraft gas turbine combustion system. In most cases statistical analysis was used to identify the correlating variables. The relationships developed for individual combustors were then correlated with combustor design and operating parameters that were influence by fuel differences.

This book was released on 2005 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers gas turbine users and manufacturers a valuable resource to help them sort through issues associated with combustion instabilities. In the last ten years, substantial efforts have been made in the industrial, governmental, and academic communities to understand the unique issues associated with combustion instabilities in low-emission gas turbines. The objective of this book is to compile these results into a series of chapters that address the various facets of the problem. The Case Studies section speaks to specific manufacturer and user experiences with combustion instabilities in the development stage and in fielded turbine engines. The book then goes on to examine The Fundamental Mechanisms, The Combustor Modeling, and Control Approaches.

Available in PDF, EPUB and Kindle. Book excerpt: November, 2008 Anna Schwarz, Johannes Janicka In the last thirty years noise emission has developed into a topic of increasing importance to society and economy. In ?elds such as air, road and rail traf?c, the control of noise emissions and development of associated noise-reduction techno- gies is a central requirement for social acceptance and economical competitiveness. The noise emission of combustion systems is a major part of the task of noise - duction. The following aspects motivate research: • Modern combustion chambers in technical combustion systems with low pol- tion exhausts are 5 - 8 dB louder compared to their predecessors. In the ope- tional state the noise pressure levels achieved can even be 10-15 dB louder. • High capacity torches in the chemical industry are usually placed at ground level because of the reasons of noise emissions instead of being placed at a height suitable for safety and security. • For airplanes the combustion emissions become a more and more important topic. The combustion instability and noise issues are one major obstacle for the introduction of green technologies as lean fuel combustion and premixed burners in aero-engines. The direct and indirect contribution of combustion noise to the overall core noise is still under discussion. However, it is clear that the core noise besides the fan tone will become an important noise source in future aero-engine designs. To further reduce the jet noise, geared ultra high bypass ratio fans are driven by only a few highly loaded turbine stages.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of variations in properties and characteristics of liquid hydrocarbon-base fuels in gas turbine engine combustors was investigated. Baseline fuels consisted of military-specification materials processed from petroleum and shale oil. Experimental fuels were comprised of liquid petroleum blends that were prepared specifically to exhibit desired physical and chemical properties. These fuels were assessed for their influence on ignition and performance characteristics in combustors of the F100, TF30, and J57 (TF33) engines at simulated operating conditions. In general, during relatively short duration tests, combustor ignition and performance became increasingly poorer as fuel quality deviated from specification or historical values. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Combustion and Heat Transfer in Gas Turbine Systems is a compilation of papers from the Proceedings of an International Propulsion Symposium held at the College of Aeronautics, Cranfield in April 1969. This compilation deals with research done by academic and scientific institutions and of industrial organizations, with some research papers covering atomization, fuels, and high-temperature materials. One paper describes the combustion system of the Concorde engine used in commercial flights, temperature of metal parts, and some design modifications to increase the mechanical life of the combustion system. Another paper discusses the evolution of the RB 162 combustion system that is used in the vertical takeoff and landing aircrafts. The RB 162 has many design features of the earlier single reversal chamber and differs in only one or two points. The book then notes the necessity of a plenum chamber burning to further development of supersonic engines and flight. One paper also proposes an alternative theory to the traditional ignition theory of altitude relighting such as those developed by Lewis and von Elbe. Another paper reposts on some observations made of the atomizing characteristics of air-blast atomizers and proposes simple changes to improve the performance of the atomizer by prefilming and allowing air to both sides of the fuel. This compilation will prove very helpful for aeronautical engineers, aviation designers, physicists, students of engineering, and readers who are interested in the design and development of jet engines and supersonic aircrafts.

Available in PDF, EPUB and Kindle. Book excerpt: This program is an analytical study correlating fuel properties and engine design and operating parameters with engine combustion performance and hot section (combustor and turbine) durability. Standard fuel specification data and fuel composition data are considered, along with special fuel properties and characteristics not routinely measured. Engine combustor design parameters considered are fuel injection and atomization, fuel/air mixing, residence times, temperatures and pressures, and flow velocities and other important design parameters. Engine performance parameters include low temperature starting and high altitude relight, flame stability (i.e. lean blow-off limits), combustion efficiency, exhaust emissions including smoke, and thermal loading of the combustor liner and turbine nozzles. Data for this program were obtained from recent and current Aero Propulsion Laboratory sponsored programs, NASA programs, and similar work performed by other Government agencies and industry.
