The use of smart actuators, in a modular braking system architecture, offers the possibility of simplifying central braking control and of developing versatile standard components applicable to braking systems in different families of aircraft. The SAMBA (Smart Actuator and Modular Braking Application) project has investigated these possibilities together with techniques for control of brake torque instead of brake pressure.
Within the frame work of Brite-Euram programme CRASURV ‘Commercial Aircraft — Design for Crash Survivability’, technology is being developed for the design of composite air frames with respect to crashworthiness. A significant part of the project consists of the design, fabrication and drop-testing of two representative composite fuselage sections, to generate the experimental data needed for the validation of new energy absorbing structural concepts, validation of simulation tools to model and analyse these structures subjected to crash loads.
Research in normal operational environments indicates that the formal requirements for the aircraft maintenance system are frequently not fully or effectively implemented in practice. This gives rise to a pervasive ‘double standard’ with no effective means of reconciling official and unofficial operational practice. A systems strategy for human-centred management in aircraft maintenance is being developed in a number of European projects, which address issues of design, planning, operational practice, monitoring, change and competence.
In this paper a brief overview of the aircraft icing problem and EURICE project structure, objectives, results and exploitation of results will be presented. The EURICE project is part of the EC Fourth Framework Programme (research and technological development programme for the years 1994–1998).
This paper provides an overview of the aeronautics sector in Greece in its present status and its perspectives in a rapidly changing environment. It briefly makes a reference to the background which is important for understanding the factors that shaped the sector's development and describes the present situation with emphasis on existing research capabilities and recent R T D activities. Furthermore, the stimulating actions of the relevant public authority responsible for research and technology in Greece are highlighted in the context of its policy to promote development of high-tech sectors.
Conventional methods of repair for metallic aircraft structures usually include the use of bolted or riveted metallic reinforcement by introducing the cutting of damaged areas, which is not suggested in aging cases, due to the reduction of strength. Although today the bonded repairs are considered more efficient than the mechanically fastened, each repair is looked-upon as tailored made for each job. However, for the industrial engineering and maintenance production line, there is a lack of appropriate technical manuals - standards and specifications to control the implementation of the repair as integrated method - from the design phase, up to application and quality assurance.
