数学模型是包含代数方程和布尔逻辑的一系列算法。在肯尼迪航天中心,航天飞机系统的数学模型利用Honeywell 66/80数字式计算机、ModcompⅡ/45小型计算机及特殊用途的硬件模拟器(微型计算机)进行。航天飞机地面操作模拟器(SGOS)为记录、维护和执行模型提供系统语言格式、子程序、排队方案和执行方法的应用软件。本文阐述的地面系统主要包括液氧和液氢低温推进剂系统、液氧外贮箱(ET)氧气排放防护罩/支架以及飞行器装配大楼(VAB)高跨间等。数学模型的用途是模拟地面硬件系统及用更优越的方法提供模拟试验环境。这就使工程技术人员可能用它来验证飞行器加注和发射的应用软件,用它来验证发射操作系统(LPS)内测试、控制和监视分系统(CCMS)的正确性。数学模型也用于操作人员的训练以及预测系统在各种状态下的反应和状况(正常操作、紧急和临时操作状态),其中包括未经验证的状态或那些在真实状态下进行尝试是太危险的状态(即故障状态)。
The mathematical model is a series of algorithms that contain algebraic equations and Boolean logic. At the Kennedy Space Center, mathematical models of the space shuttle system were made using Honeywell 66/80 digital computers, Modcomp II / 45 minicomputers, and special-purpose hardware simulators (minicomputers). The Space Shuttle Ground Simulator (SGOS) is a software application that provides system language formats, subroutines, queuing schemes and execution methods for recording, maintaining, and executing models. The ground systems described in this paper include liquid oxygen and liquid hydrogen cryogenic propellant systems, ET Oxygen exhaust hoods / brackets, and the VAB high rise span. The purpose of the mathematical model is to simulate terrestrial hardware systems and to provide simulated test environments in a superior way. This allows engineers and technicians to use it to validate aircraft filling and launching applications and use it to verify the correctness of the Test, Control and Surveillance Subsystem (CCMS) within a Launch Operating System (LPS). Mathematical models are also used for operator training and for predicting system reactions and conditions in various states (normal operation, emergency and temporary operating conditions), including unverified conditions or those that are attempted in real conditions are too dangerous State (ie fault status).
