We provide an overview of the DAME project, and a discussion of the progress made to date on the development of a distributed aeroengine diagnosis environment as a proof of concept demonstration for grid computing. We discuss the development of a demonstration diagnosis workbench system for this complex, data intensive, diagnosis application that must be operated as a distributed 'virtual organisation'. We describe the core diagnosis applications that have been implemented as grid services, and explain how these services are being deployed within the overall diagnosis process

Aero engines are extremely reliable machines and operational failures are rare. However, currently great effort is being put into reducing the number of in-flight engine shutdowns, aborted take-offs and flight delays through the use of advanced engine health monitoring technology. This represents a benefit to society through reduced delays, reduced anxiety and reduced cost of ownership of aircraft. This is reflected in a change of emphasis within companies such as rolls-royce Plc where instead of selling engines to customers there is a fundamental shift to adoption of power-by-the-hour contracts. In these airlines make fixed regular payments based on the hours flown and the engine manufacturer retains responsibility for maintaining the engine. To support this new approach, improvements in in-flight monitoring of engines are being introduced with the collection of much more detailed data on the operation of the engine. At the same time advances have been made in Internet technologies providing a worldwide network of computers that can be used to access and process that data. The explosion of available knowledge within those large datasets also presents its own problems and here it is necessary to work on advanced decision support systems to identify the useful information in the data and provide knowledge-based advice between individual aircraft, airline repair and overhaul bases, world-wide data warehouses and the engine manufacturer. This paper presents a practical framework in which to build such a system that is inherent in the emerging Grid computing paradigm that provides the necessary computing resources. A demonstrator system already developed and implemented within the UK e-Science Grid project DAME is also introduced. © Springer-Verlag Berlin Heidelberg 2004.

Over the past 10 years there have been rapid advances in wireless and internet technologies. In the case of Fieldbuses many years of standardisation effort have failed to produce a single standard. However, the availability of cheap Ethernet-based networking hardware and PC technology driven by the huge office IT market coupled with the explosion of Internet has made Ethernet an attractive proposition for control and monitoring systems. This has led to parallel developments in Industrial Ethernet and standards specific to the aviation industry. Additionally, the advent of low cost mobile telephone technology and wireless interconnect for PC and electrical goods is driving interest in the adoption of this technology in other areas. Already products are appearing on the market which exploit this technology and many applications exist. This overview presents an introduction and overview of the current state of the technology as a result of studies performed by the author for rolls-royce into potential exploitation of these technologies in rolls-royce aircraft, marine and industrial systems. In particular, the application of Ethernet and wireless technologies for on-board systems, remote operational monitoring, testing and control will be considered.

This paper focuses on multi-objective optimisation of staged combustion control for aviation gas turbine engines. Pareto optimisation based multi-objective genetic algorithms are used to design the fuel distribution control laws of a staged combustor. The results of control system parameter optimisation over International Civil Aviation Organisation Landing and Take-off cycle and the typical engine operation condition are presented. An analysis of the control-related issues for optimal fuel distribution is presented. Copyright © 2002 IFAC.

A family-oriented software development process for engine controllers

This paper presents a software engineering process that includes family-based aspects for aero-engine control software. The process uses a "family capability" derived from family analysis of the embedding system. This analysis allows reuse capability to be designed into the process by exploiting prior knowledge of the differences between members of an engine family. The process described follows the traditional software lifecycle. However, the nature of the stages is modified to incorporate the use of the family capability, essentially to allow systematic application of both compositional and generational reuse throughout the development process. The process described was evaluated on a trial project to develop, and subsequently modify, a thrust reverser system for a small aero-engine. Initial results show that this process can reduce effort for both initial and subsequent developments through the use of the family capability. © Springer-Verlag Berlin Heidelberg 2001.

Multi-Disciplinary Optimisation Applied to a Vertical Lift control System

引用

IFAC Proceedings Volumes 2000年第26期33卷 729-734页

作者： H.A. Thompson P.J. Fleming Rolls-Royce University Technology Centre in Control and Systems Engineering Department of Automatic Control and Systems Engineering University of Sheffield Mappin Street Sheffield SI 3JD United Kingdom

The design of complex systems such as the Lift control System for a vertical take-off and landing aircraft poses challenging problems. It is necessary to consider the design of the system from the point of view of many design disciplines to optimise acquisition and operating support costs, weight, maintainability and availability of the system. A design process, based on multiobjective optimisation and employing evolutionary computing methods is described and its application demonstrated on this application.

A Smart Actuator for Fault-Tolerant control

引用

IFAC Proceedings Volumes 2000年第11期33卷 807-812页

Recent advances in smart actuator and fieldbus technologies are promoting changes in fault-tolerant control design issues. In this paper, a smart actuator scheme is implemented based on a low-cost stepper-motor and CAN bus interface. In order to enhance fault-tolerance capability of the control system, the proposed scheme is focused on self-diagnosis and self-compensation of undesirable actuator characteristics produced by faults. Experimental results with a distributed architecture demonstrator show that actuator faults can be accommodated successfully without a redundant actuator by using the proposed smart actuator scheme.
