This SAE Aerospace Recommended Practice (ARP) provides performance station designation and nomenclature systems for aircraft propulsion systems and their derivatives.

This SAE Aerospace Standard (AS) provides classical propulsion system performance parameter names for aircraft propulsion systems and their derivatives, and describes the logical framework by which new names can be constructed.

This SAE Aerospace Standard (AS) provides a performance station designation system for aircraft propulsion systems and their derivatives. The station numbering conventions presented herein are for use in all communications concerning propulsion system performance such as computer programs, data reduction, design activities, and published documents. They are intended to facilitate calculations by the program user without unduly restricting the method of calculation used by the program supplier. The contents of this document were previously a subset of AS755E. Due to the growing complexity of station numbering schemes and an industry desire to expand nomenclature descriptions, a decision was made to separate the “station numbering” and “nomenclature” contents of AS755 into two separate documents. AS755 will continue to maintain standards for station numbering. SAE Aerospace Standard AS6502 will maintain standards for classical nomenclature moving forward.

This SAE Aerospace Recommended Practice (ARP) specifies a set of functions and their expected behavior that constitute an Application Programming Interface (API) for gas turbine engine customer programs. The main body of this document contains a description of each of the API function calls and of the data that passes through these functions. Implementations of this API in specific programming languages are contained in separate appendices. These appendices include language specific details and the definitions for each function as required for the given language. AS681 is the parent document of ARP4868. All of AS681 applies to customer engine programs written to conform to this document.

The SAE Aerospace Standard document AS681 is the parent document of this SAE Aerospace Recommended Practice (ARP). AS681 applies to Engine programs written to conform to this document. This ARP specifies a set of functions and their expected behaviors that constitute a function based Application Program Interface (API) for gas turbine engine customer programs. The functions specified in this API are delivered by the Supplier as part of the Engine model.

This document defines generic language independent functions and specific appendices for implementations in C and Fortran.

The function based API specified in this ARP represents an alternative to the Fortran COMMON block structure, as specified in AS4191, historically used to communicate with an engine program. The customer may request emulation of the AS4191 interface if desired.

Engine test data reduction programs may range from programs which are limited to calculation of external performance, e.g. thrust, fuel flow, and airflow, to those which include an analysis of component performance for consistency checks.

This Aerospace Recommended Practice (ARP) describes a class of digital computer programs for use by organizations other than the engine supplier for reduction of engine test data relating to the interface of the engine in the airframe or test facility. This ARP also is intended as a guide for the preparation of such computer programs.

This SAE Aerospace Recommended Practice (ARP) provides guidance for the presentation of gas turbine engine transient performance models with the capacity to be implemented as digital computer programs operating in real time and is intended to complement ARP1257 and AS681. Such models will be used in those applications where a transient program must interface with physical systems. These applications are characterized by the requirement for real time transient response. These models require attention to unique characteristics that are beyond the scope of ARP1257. This document is intended to facilitate the development of mathematical models and the coordination of their requirements with the user. It will not unduly restrict the modeling methodology used by the supplier. The objective of this document is to define a recommended practice for the delivery of mathematical models intended for real time use.

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.
