Aircraft maintenance is crucial to make flying a safe experience. Even a thin crack in a component can lead to an air crash. CIT's NDT Filmfree Digital Radiography enables you to carry out NDT Inspection of majority of aerospace components.
Digital Radiography has the ability to inspect metals, non metals as well as low and high density materials. Therefore, with respect to aerospace, it is appropriate for inspecting the following components:
> Turbine blades
> Air craft wings
> Landing gears
> Box sections
> Honeycomb structures
The use of advanced composite materials in aircraft has drastically increased over the last two decades and is now including the production of safety critical parts. Composites suffer from defects, which are considerably different from those found in traditional aerospace materials. Similarly, Non-Destructive Testing (NDT) inspection techniques required to detect these defects will vary considerably from traditional methods. The major hurdle in the development of NDT techniques specifically for composites is the inhomogeneous structure of composites, which inhibits the use of NDT methods in their current form that rely on the material being homogeneous and a defect representing an inhomogeneous entity.
A number of NDT techniques, that overcome the limitations of current NDT techniques, will be developed to inspect composites at the manufacturing stage and then in service as components of an assembled aircraft. The consortium proposes to develop new and novel NDT techniques, sensors and systems for the inspection of advanced composites in aircraft. The novel NDT techniques developed will be based on ultrasonic, X-ray, thermography, resonance and laser shearography NDT methods. Hence, the project will develop a suite of NDT sensors and techniques capable of delivering solutions to the total inspection requirements of the aerospace composite industry.
