An Advanced Structural Integrity System for Air Transport Composites using NDT Evaluation and Damage Tolerance Methods

Automatic Rail Inspection InRail

It is well known that aircrafts’ safety is of great importance, resulting in thorough inspections by the aerospace industries for possible defects /flaws, both during the assembly and in service life stages. Part of the maintenance procedures implies the structural integrity inspection through the aid of Non Destructive Testing (NDT) techniques, aiming to detect structural defects in damaged or flaw components and prevent a catastrophic failure by substituting or repairing them. Airworthiness authorities casually refer these inspections as “Checks” categorised in a scale from A to D Checks. The main disadvantage of these Checks is that they require a lot of time and they can only be performed in large hangars or into appropriate modulated spaces where NDT facilities can be accommodated.

Aim of the TRACE-IT project is to build a new and novel method focused upon the development of an innovative inspection system, with automated and manual capabilities, for any type of composite aircraft structures. The structural integrity system is comprised by a qualified ultrasonic Phase Array (PA) method attached to a mobile manipulating system and a Damage Tolerance (DT) assessment numerical technique.

The aim of the project was to develop an integrated NDT system to improve risk and integrity assessment of rail systems. In particular Visual and Magnetic AC-Susceptibility methods for fast and reliable assessment of track failure and damage were combined with State of the art Acoustic and Ultrasonic portable devices to gain critical information and performance of critical rail components. In parallel an innovative and in-situ chemical analysis system was developed, which was used in combination with modern established analytical techniques to charactrise in-situ degradation of rail materials.

PROJECT - Blast Modelling

Vapour Cloud Explosion Modelling

We have been involved in modelling a Vapour Cloud Explosion for a large multinational Oil and Gas industry. The goal was to address and estimate damage in buildings subject to  blast loads. Our analysis involved a multi-physics simulation where the shock wave induced large deformation and damage to the buildings. A careful analysis was carried out to assess blast loads and fragment generation. Potential damage and injury were predicted using state-of-the-art computational fluid dynamics and transient structural analysis.

We developed a tailored mitigation and protection strategy with a novel blast resistant structural design.
