Airbus is a leading aircraft manufacturer with the position as technology driver and a distinct customer orientation, broad commercial know-how and high production efficiencies. It is constantly working on further and new development of its products from ecological and economical points of view. Fuel Cell Systems (FCS) on board of an aircraft provide a good opportunity to address both aspects. Based on existing and upcoming research results it is necessary to find trend-setting measures for the industrial implementation and application of this technology. Past and current research efforts have shown good prospects for the industrial implementation and application of the fuel cell technology. Being an efficient source of primarily electric power the fuel cell would be most beneficial when used in conjunction with electrical systems.

The introduction of Fly-By-Wire (FBW) and the increasing level of automation contribute to improve the safety of civil aircraft significantly. These technological steps permit the development of advanced capabilities for detecting, protecting and optimizing A/C guidance and control. Accordingly, this higher complexity requires extending the availability of aircraft states, some flight parameters becoming key parameters to ensure a good behaviour of the flight control systems. Consequently, the monitoring and consolidation of these signals appear as major issues to achieve the expected autonomy. Two different alternatives occur to get this result. The usual solution consists in introducing many functionally redundant elements (sensors) to enlarge the way the key parameters are measured. This solution corresponds to the classical hardware redundancy, but penalizes the overall system performance in terms of weight, power consumption, space requirements, and extra maintenance needs.

Reducing Energy Use in Aircraft Component Manufacture - Applying Best Practice in Sustainable Manufacturing

Rising energy costs and increased regulation in recent years have caused industrialists to investigate how to apply ‘energy efficiency’ to their manufacturing operations. As well as reducing operating costs, the benefits of a ‘green’ image as a market differentiator are beginning to be realised. The literature describes the successful implementation of a variety of approaches to energy reduction, with particular focus on energy intensive industries (such as foundries) and on improvements to building services (such as lighting). However, a systematic approach to applying sustainable practices to the manufacturing processes involved in the production of high value products, such as aircraft, is noticeably absent. This paper describes how a number of sustainable manufacturing approaches have been combined, enhanced and applied to the shop floor of a manufacturing facility in the UK responsible for the production of large component assemblies for the aerospace industry.
