Download or read book Second Generation Gas turbine Engines Discussion of Turbofan Engines written by Hsiao Ling and published by . This book was released on 1968 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbojet aircraft fly at a speed exceeding 2000 km/hr and have a higher rate of fuel consumption. Mig-15 and Tu-104 aircraft powered by turbojet engines have a fuel consumption rate of 0.8-1.0 kg per 1-kg thrust per hr. Turboprop engines were developed for the purpose of fuel economy. Turboprop engines have similar construction and operate on the same principle as a turbojet engine. The only difference in a turboprop engine is the addition of a propeller outside the compressor. Turboprop engines are built for long-range civil transport airplanes flying at a speed of 800-900 km/hr. Turboprop engines can also be used in military aircraft having a flying speed of 4-4.5 mach if an afterburner is added. Tests showed that the fuel consumption of turboprop engines is reduced 16-20% under the same internal flow condition. Takeoff thrust is also increased 30-40% and engine noise is reduced 10-15 db. Turboprop engines, however, are more complicated in construction, heavier, and larger in diameter (30-40%) than turbojet engines. More than 40 types of turboprop engines have been developed recently. A small turboprop engine capable of producing a thrust of only 300 kg is in process of development. A large turboprop engine having a thrust of 9000-10000 kg and a fuel consumption rate of 0.51-0.54 kg per 1-kg thrust per hr has been developed. Middle-range Tu-124 passenger airplanes powered by turboprop engines have a fuel consumption rate 15-25% lower than Tu-104 airplanes. (Author).

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.

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.

Download or read book Modern Gas Turbine Systems written by Peter Jansohn and published by Elsevier. This book was released on 2013-08-31 with total page 849 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern gas turbine power plants represent one of the most efficient and economic conventional power generation technologies suitable for large-scale and smaller scale applications. Alongside this, gas turbine systems operate with low emissions and are more flexible in their operational characteristics than other large-scale generation units such as steam cycle plants. Gas turbines are unrivalled in their superior power density (power-to-weight) and are thus the prime choice for industrial applications where size and weight matter the most. Developments in the field look to improve on this performance, aiming at higher efficiency generation, lower emission systems and more fuel-flexible operation to utilise lower-grade gases, liquid fuels, and gasified solid fuels/biomass. Modern gas turbine systems provides a comprehensive review of gas turbine science and engineering. The first part of the book provides an overview of gas turbine types, applications and cycles. Part two moves on to explore major components of modern gas turbine systems including compressors, combustors and turbogenerators. Finally, the operation and maintenance of modern gas turbine systems is discussed in part three. The section includes chapters on performance issues and modelling, the maintenance and repair of components and fuel flexibility. Modern gas turbine systems is a technical resource for power plant operators, industrial engineers working with gas turbine power plants and researchers, scientists and students interested in the field. Provides a comprehensive review of gas turbine systems and fundamentals of a cycle Examines the major components of modern systems, including compressors, combustors and turbines Discusses the operation and maintenance of component parts
