This book was released on 1971 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Present and near-future requirements for the addition of digital computer simulation of gas turbine engine steady-state and transient performance to the present Engine Test Facility and Propulsion Wind Tunnel Facility digital data capability were determined based on information and guidance provided by the Air Force Aero Propulsion Laboratory and various gas turbine engine manufacturers. During Phase I of this study, digital computer high-speed core memory size and throughput times were determined and are presented for several modern steady-state and transient mathematical model simulation programs. Display requirements were also determined and are presented for full utilization of the mathematical model results, off-line and on-line. Some preliminary results on dynamic compressor mathematical models are discussed. (Author).

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The research study focuses on the idea of simulation of an Integrated FullElectric Propulsion System. The simulation required the development of a gasturbine performance model that could predict the dynamic behaviour of theengine in response to a fluctuation of electrical load. For this purposes it wasnecessary to evaluate the thermodynamic working process of the gas turbineand a computer code was created. A design point model written in FORTRAN77 had been transformed to predict the steady state and transientperformance of a two-shaft gas turbine and single shaft gas turbine. Themodels were based on the thermodynamic law of conservation of mass. Forthe model of the two-shaft gas turbine controls system equations had beenderived from off-design analysis and implemented as handles for operation. Both the models were then transformed to a direct link library for theSIMULINK? package. They were further implemented with an electricalnetwork model to form a high-fidelity prime mover-electrical networkpropulsiondrive interface with which a complete systems analysis was doneto understand the response of the three systems in parallel. In a second part heat exchanger modelling had to be performed so as tocreate a gas turbine model of an intercooled-recuperated engine. This wasdone for the steady state behaviour and sizing problem of heat exchangers. The models were run parallel to the steady state code as a validationexercise. Due to time and project restraints the complete incorporation of themodels with the gas turbine code was not performed and only a uni-directionalsystem of heat exchanger was created. Over all the period of researchparametric studies had been done for comparison of various aspects ofperformance. The high fidelity model of the prime mover-electrical network highlighted thereasons for studying the impact of the propulsion drive and electrical networkload dynamics on the operation of the prime movers and vice versa. The loss-of-propulsion-load scenario case study has demonstrated the capabilities ofthe integrated model, showing clear interactions between the individualsubsystems. The interface can now be used to analyse novel types of gasturbine engines in the future. The method adopted to simulate transientperformance of gas turbines was useful in understanding the impact of bleedair on current and novel cycles. Finally the task of heat exchanger simulationemphasized the need to create better and accurate models to understand theimpact of its behaviour on the gas turbine.

This book was released on 2019-11-25 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second revised and enhanced edition of the book Gas Turbine Design, Components and System Integration written by a world-renowned expert with more than forty years of active gas turbine R&D experience. It comprehensively treats the design of gas turbine components and their integration into a complete system. Unlike many currently available gas turbine handbooks that provide the reader with an overview without in-depth treatment of the subject, the current book is concentrated on a detailed aero-thermodynamics, design and off-deign performance aspects of individual components as well as the system integration and its dynamic operation. This new book provides practicing gas turbine designers and young engineers working in the industry with design material that the manufacturers would keep proprietary. The book is also intended to provide instructors of turbomachinery courses around the world with a powerful tool to assign gas turbine components as project and individual modules that are integrated into a complete system. Quoting many statements by the gas turbine industry professionals, the young engineers graduated from the turbomachinery courses offered by the author, had the competency of engineers equivalent to three to four years of industrial experience.

This book was released on 1974 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steady state engine performance programs discussed in this Standard will be confined to two basic performance categories: preliminary design or specification. Preliminary design programs may vary in scope, but will be representative of the defined engine performance until the engine is defined by a specification. A specification program will accurately represent the engine described by the specification and will identify the appropriate model specification. Normally, the computer program will be the primary source of performance data.Two additional categories of program are status and data reduction interface programs, which are covered by ARP 1211 and 1210 respectively.
