Abstract

The project's goal was to examine, confirm and exploit the successful results of these techniques, using fundamental materials research on fatigue loading, and to apply them to the particular field of aeronautics. The project included progressive microdamage and fatigue monitoring of aircraft components and structures, sensor engineering, development of NEWS-based imaging methods, and fundamental research on the modelling of meso-scale damage phenomena. It aimed to investigate the relation of these studies to the macroscopic behaviour of progressively fatiguing materials, and formulate the design of a unique system for microdamage inspection, including remote control and communication tools, and the completion of a full-scale model validation. The long-term goal of the project (5-10 years) is to monitor while in operation, the integrity of airframes and aircraft engines, and helicopter rotor systems. The development of this innovative NEWS-based technology and its engineering applications to aeronautics, will result in an enhanced, reliable and integrated measurement system and protocol for microcrack diagnostics of aircraft components and structures. This development is expected to result in a significant increase in aircraft and passenger safety while contributing to substantial cost savings through a decrease in maintenance and operating times. Methodology The AERONEWS project integrated activities in three sections: fundamental and applied research technological development and innovation related activities validation and training. The emphasis of the project methodology is on the development and perfection of suitable techniques and knowledge enhancement of NEWS so that it can be used for both the current and extended non-destructive evaluation (NDE) methods and applications in the field of aeronautics. The working flow-chart of the project incorporates all the steps required for the practical implementation of NEWS technology. Activities dealt with: fundamental and applied research; technological developments; validation of the proposed product; dissemination activities.
