本SAE航空航天推荐规程（ARP）为燃气涡轮发动机瞬态性能模型的呈现提供了指导，该模型能够实现为实时运行的计算机程序，旨在补充AS681。 这种模型将用于瞬态程序必须与物理系统接口的那些应用中。这些应用的特点是需要实时瞬态响应。 这些型号需要注意AS681范围之外的独特特征。本文件旨在促进数学模型的开发以及与用户协调其要求。它不会过度限制供应商使用的建模方法。 本文件的目的是定义用于实时使用的数学模型交付的推荐实践。本申请中使用的模型也可以包含在AS681涵盖的可交付计算机程序中。

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.
