Book excerpt: Design studies and an experimental test program were conducted to provide basic technology and preliminary flight-weight designs for a small (2-5 lb/sec total engine airflow) high temperature rise combustor with a 3000F exit temperature, as a first step towards demonstration in an advanced engine. Tests were conducted to evaluate the combustor design parameters developed in the initial design study phase of the program pertaining to liner cooling techniques, primary-diluent air mixing, fuel introduction and patternization, and primary zone performance. The preliminary designs optimize the technology developed in this program and comprise both annular and can end-mounted combustor configurations incorporating an annular vaporizer fuel introduction system and transpirationally cooled liners.

This book was released on 2020-04-19 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leadership in gas turbine technologies is of continuing importance as the value of gas turbine production is projected to grow substantially by 2030 and beyond. Power generation, aviation, and the oil and gas industries rely on advanced technologies for gas turbines. Market trends including world demographics, energy security and resilience, decarbonization, and customer profiles are rapidly changing and influencing the future of these industries and gas turbine technologies. Technology trends that define the technological environment in which gas turbine research and development will take place are also changing - including inexpensive, large scale computational capabilities, highly autonomous systems, additive manufacturing, and cybersecurity. It is important to evaluate how these changes influence the gas turbine industry and how to manage these changes moving forward. Advanced Technologies for Gas Turbines identifies high-priority opportunities for improving and creating advanced technologies that can be introduced into the design and manufacture of gas turbines to enhance their performance. The goals of this report are to assess the 2030 gas turbine global landscape via analysis of global leadership, market trends, and technology trends that impact gas turbine applications, develop a prioritization process, define high-priority research goals, identify high-priority research areas and topics to achieve the specified goals, and direct future research. Findings and recommendations from this report are important in guiding research within the gas turbine industry and advancing electrical power generation, commercial and military aviation, and oil and gas production.

This book was released on 2016-08-09 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.

Book excerpt: Gas turbine engines have long used fuel on its way to the combustor as a coolant for engine components. Advanced aircraft and engine technologies are demanding more cooling capacity than conventional fuel delivery systems can offer. To meet these new cooling requirements, technologies are being pursued to allow fuel to reach significantly higher temperatures without the traditional limitations associated with coking. A compact fuel/air heat exchanger is a critical component in these new high-temperature fuel systems. Both tubular metal foam and hollow-truss cellular metal heat exchangers were examined for performance, size, and weight benefits as compared to conventional shell-tube technology. The tubular metal foam heat exchanger behavior was characterized with scaled laboratory and full-scale rig experiments. The data were used to calibrate an analytical model based on data in the open literature. The results indicate that sintered metal foam can provide as much as twice the heat transfer as a plain bank of staggered tubes. However, the corresponding 4X increase in pressure drop almost neutralizes the heat transfer benefit. Furthermore, it was determined that metal foam manufacturing constraints combined with the small high pressure fuel tubes would result in a design which has no size/weight or performance benefit. However a 40 % reduction in the number of tubes may provide improved reliability. A preliminary investigation of a hollow-tube cellular metal heat exchanger found that when elliptical non-flowing rods are used to augment the tube-bank they can increase the heat transfer by as much as 1.5X over a plain staggered tube-bank without a significant increase in pressure drop. It is projected that 10 % weight and 30 % size reductions can be achieved with hollow-truss cellular metal as compared to shell-tube heat exchanger. However, realization of hollow-tub cellular metal may require a costly manufacturing process.

Available in PDF, EPUB and Kindle. Book excerpt: A joint Army/NASA program was conducted to design, fabricate, and test an advanced, reverse-flow, small gas turbine combustor using a compliant metal enhanced (CME) convection wall cooling concept. The objectives of this effort were to develop a design method (basic design data base and analysis) for the CME cooling technique and tben demonstrate its application to an advanced cycle, small, reverse-flow combustor with 3000 F (1922 K) burner outlet temperature (BOT). The CME concept offers significant improvements in wall cooling effectiveness resulting in a large reduction in cooling air requirements. Therefore, more air is available for control of burner outlet temperature pattern in addition to the benefit of improved efficiency, reduced emissions, and smoke levels. Rig test results demonstrated the benefits and viability of the CME concept meeting or exceeding the aerothermal performance and liner wall temperature characteristics of similar lower temperature-rise combustors, achieving 0.15 pattern factor at 3000 F (1922 K) BOT, while utilizing approximately 80 percent less cooling air than conventional, film-cooled combustion systems.
