An effective GSS is vital to the successful implementation of an EMS and is a fundamental part of the total monitoring system design, including asset management. Unlike the on-board part of the EMS which principally uses real time data to indicate when engine maintenance is required, a GSS can offer much greater processing power to comprehensively analyze and manipulate EMS data for both maintenance and logistics purposes. This document reviews the main EMS functions and discusses the operating requirements used to determine the basis design of a GSS, including the interfaces with other maintenance or logistic systems. A brief discussion is also included on some of the more recent advances in GSS technology that have been specifically developed to provide more effective diagnostic capabilities for gas turbine engines.

The objective of any organization, as part of continual improvement, is to reduce the number of issues (i.e., undesirable conditions, defects, failures) and to minimize their impact on quality, delivery performance, and cost. This includes having processes in place to detect and eradicate significant and recurrent issues, which implies having well identified problems, a common understanding of their impact and associated root causes, and having defined and implemented adequate actions so that these problems, including similar issues will not happen again.

ARP7998
This is a recommended practice for an interface to supplier simulations that utilize traditional interprocess communication (IPC) methods of shared memory and semaphore communications. These IPC methods are fairly standard practice in the computer science world, that allow for communication by separate processes running on a computer without any common runtime requirements of each process being run. So 32bit applications can talk with 64 bit applications as well as any other compiler or runtime dependency being needed by the calling program to interface with the called system. This also allows the calling program and the called program to be run on separate CPUs to allow parallel execution of the called program as well as multiple instances of the called program to execute all on separate processors.

This document provides a review of published methods that have been used to provide estimates of the levels of distortion and/or the concomitant loss of stability pressure ratio that can occur when the recommended full complement of aerodynamic interface plane high-response instrumentation is not used when obtaining inlet data. The methods have been categorized based on the underlying mathematical representation of the aerophysics. Further, the use of maximum value statistics, which has been used to further improve the results where short-duration time records have been employed, is discussed.

Three levels of fan structural analysis are included in this practice: 1. Initial Structural Integrity 2. In-vehicle Testing 3. Durability Test Methods The Initial Structural Integrity section describes analytical and test methods used to predict potential resonance and, therefore, possible fatigue accumulation. The In-vehicle (or machine) section enumerates the general procedure used to conduct a fan strain gage test. Various considerations that may affect the outcome of strain gage data have been described for the user of this procedure to adapt/discard depending on the particular application. The Durability Test Methods section describes the detailed test procedures that may be used depending on type of fan, equipment availability, and end objective. Each of the previous levels builds upon information derived from the previous level. Engineering judgment is required as to the applicability of each level to a different vehicle environment or a new fan design.

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.

This SAE Standard specifies a method for measuring the deflection of friction materials, noise insulators, and disc brake pad assemblies to be used in road vehicles with a Gross Vehicle Weight Rating below 4336 kg. This part of the SAE J3079 includes the test for deflection and creep at various pressures under ambient temperature conditions. This SAE test method differs from SAE J2468 and ISO 6310 in the preload and maximum load applied to the test sample when deflection is measured. It also introduces additional measurements such as for deflection offset, hysteresis, and creep.

This recommended practice describes a process for testing the comprehension of static (i.e., fixed or non-dynamic) symbols for all ground vehicles, for both OEM and aftermarket products. With advancing display technology, it is now possible to display dynamic symbols (e.g., a spinning beach ball to show that a process is ongoing, or a diagram showing energy distribution in hybrid vehicles). Such graphics are outside of the scope of this recommended practice, though extensions of this process may be useful for testing them. However, several symbols which occupy the same space on a display may change state without movement (e.g. play/pause button); these are within the scope of this recommended practice. The process described in this recommended practice includes criteria that are used to identify how well the perceived meaning matches the intended meaning for a representative sample of drivers.

The increase in the number of silicon foundries and CAD/CAE system and workstation companies, and the problem of movement of data among in-house design systems has made a standard interchange format for electronic design data essential. The benefits of the general adoption of a standard interchange format are important and far reaching. The customer receives a much wider variety of feasible choices, and free competition in both CAEYCAD system/tool businesses and foundry businesses is enhanced. The electronic circuit designer and customer of CAE/CAD system and foundry service can expect compatibility among these products. The designer can choose equipment and services best suited for a particular task with a minimum of overhead. Foundries can work with customers regardless of the CAE/CAD equipment that the customer is using.
