Download or read book Gas Turbine Engine Performance Presentation and Nomenclature for Digital Computers Using Object-Oriented Programming written by S-15 Gas Turbine Perf Simulation Nomenclature and Interfaces and published by . This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides recommendations for several aspects of air-breathing gas turbine engine performance modeling using object-oriented programming systems. Nomenclature, application program interface, and user interface are addressed with the emphasis on nomenclature. The Numerical Propulsion System Simulation (NPSS) modeling environment is frequently used in this document as an archetype. Many of the recommendations for standards are derived from NPSS standards. NPSS was chosen because it is an available, production system. The practices recommended herein may be applied to other object-oriented systems.While this document applies broadly to any gas turbine engine, the great majority of engine performance computer programs have historically been written for aircraft propulsion systems. Aircraft and propulsion terminology and examples appear throughout. Gas turbine engine manufacturers (suppliers) have long provided their customers with computer programs which simulate engine performance. Application manufacturers and others (customers) use these programs, often called models or simulations, in design studies, mission analysis, life cycle analysis, and performance prediction of their products. These models are used throughout the life of a product, from conceptual design through production, deployment, field use, maintenance, and overhaul. Communication between suppliers and customers is more productive and less error prone if all engine models adhere to common guidelines with respect to presentation of data and interface with other computer programs. No guidelines or reccommended parctices currently exist for Object-Oriented models.

Book Synopsis GAS TURBINE ENGINE STEADY STATE PERFORMANCE PRESENTATION FOR DIGITAL COMPUTER PROGRAMS by : S-15 Gas Turbine Perf Simulation Nomenclature and Interfaces
Download or read book GAS TURBINE ENGINE STEADY STATE PERFORMANCE PRESENTATION FOR DIGITAL COMPUTER PROGRAMS written by S-15 Gas Turbine Perf Simulation Nomenclature and Interfaces and published by . 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.

This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Standard (AS) provides the method for presentation of gas turbine engine steady-state and transient performance calculated using computer programs. It also provides for the presentation of parametric gas turbine data including performance, weight and dimensions computed by computer programs.This standard is intended to facilitate calculations by the program user without unduly restricting the method of calculation used by the program supplier. This standard is applicable to, but not limited to the following program types: data reduction, steady-state, transient, preliminary design, study, specification, status & parametric programs. Due to the trend towards program implementation in object-oriented languages, this document has been revised to become language independent. Also, the specifics of the traditional FORTRAN implementation have been transferred to ARP4191. Several other updates were made: additions of new engine ratings, ram pressure recovery equations, introduction of ARP5571, rewrite of sections and revision of the units. Also the power definition hierarchy is not specified anymore. It is now left for coordination between the supplier and the user.
