This book was released on 2013-07 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: In support of the Fundamental Aeronautics Program, Subsonic Rotary Wing Project, further gas turbine engine studies have been performed to quantify the effects of advanced gas turbine technologies on engine weight and fuel efficiency and the subsequent effects on a civilian rotary wing vehicle size and mission fuel. The Large Civil Tiltrotor (LCTR) vehicle and mission and a previous gas turbine engine study will be discussed as a starting point for this effort. Methodology used to assess effects of different compressor and turbine component performance on engine size, weight and fuel efficiency will be presented. A process to relate engine performance to overall LCTR vehicle size and fuel use will also be given. Technology assumptions and levels of performance used in this analysis for the compressor and turbine components performances will be discussed. Optimum cycles (in terms of power specific fuel consumption) will be determined with subsequent engine weight analysis. The combination of engine weight and specific fuel consumption will be used to estimate their effect on the overall LCTR vehicle size and mission fuel usage. All results will be summarized to help suggest which component performance areas have the most effect on the overall mission.

Book excerpt: This book is for students, teachers, and practicing engineers and describes an industrial approach to gas turbine engine simulation, mainly for aircraft propulsion. The principles of performance model creation are covered, and the viability and accuracy of model-based performance analyses are demonstrated by their application to real-world examples, where measured data are scarce. Clear distinctions are made between design and off-design models, the keys to success being the recognition of the importance of scaling and validating compressor and turbine maps. This topic is discussed in more detail than in other sources. New descriptions of turbomachinery basics are offered, and it is shown how velocity diagrams can capture the quality of a compressor or turbine stage and the effects of changes. Non-dimensional performance is explained in an unusual way, without referring to higher mathematics. The influence of inlet flow distortion and heat transfer on engine operability during transient operation is also characterized. This second edition contains new material about engine starting and windmilling, supported by how to extend existing compressor and turbine maps down to speeds as low as 1%. Unique material on map interpretation is included. The design and operation of hybrid propulsion systems are also addressed. Not only a valuable engineering textbook but also a good read!

This book was released on 2019-01-13 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, preliminary studies on two turbine engine applications relevant to the tilt-rotor rotary wing aircraft are performed. The first case-study is the application of variable pitch turbine for the turbine performance improvement when operating at a substantially lower shaft speed. The calculations are made on the 75 percent speed and the 50 percent speed of operations. Our results indicate that with the use of the variable pitch turbines, a nominal (3 percent (probable) to 5 percent (hypothetical)) efficiency improvement at the 75 percent speed, and a notable (6 percent (probable) to 12 percent (hypothetical)) efficiency improvement at the 50 percent speed, without sacrificing the turbine power productions, are achievable if the technical difficulty of turning the turbine vanes and blades can be circumvented. The second casestudy is the contingency turbine power generation for the tilt-rotor aircraft in the One Engine Inoperative (OEI) scenario. For this study, calculations are performed on two promising methods: throttle push and steam injection. By isolating the power turbine and limiting its air mass flow rate to be no more than the air flow intake of the take-off operation, while increasing the turbine inlet total temperature (simulating the throttle push) or increasing the air-steam mixture flow rate (simulating the steam injection condition), our results show that an amount of 30 to 45 percent extra power, to the nominal take-off power, can be generated by either of the two methods. The methods of approach, the results, and discussions of these studies are presented in this paper. Chen, Shu-cheng, S. Glenn Research Center

This book was released on 2018-07-20 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aerodynamic performance of the compressor-drive turbine of the DOE upgraded gas turbine engine was determined in low temperature air. The as-received cast rotor blading had a significantly thicker profile than design and a fairly rough surface finish. Because of these blading imperfections a series of stage tests with modified rotors were made. These included the as-cast rotor, a reduced-roughness rotor, and a rotor with blades thinned to near design. Significant performance changes were measured. Tests were also made to determine the effect of Reynolds number on the turbine performance. Comparisons are made between this turbine and the compressor-drive turbine of the DOE baseline gas turbine engine. Roelke, R. J. and Haas, J. E.
