GAS TURBINE ENGINE INTERFACE TEST DATA REDUCTION COMPUTER PROGRAMS

1990-11-01
HISTORICAL
ARP1210B
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.

Function-Based API for Gas Turbine Engine Performance Programs

WIP
ARP4868D

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.

ARP4868
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.

Gas Turbine Engine Real Time Performance Model Presentation

2015-03-09
CURRENT
ARP4148C
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 computer programs operating in real time and is intended to complement 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 AS681. 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. Models used in this application may also be contained in deliverable computer programs covered by AS681.
