FLY-BAG 2 - Nuovi dispositivi anti-esplosione pronti per essere installati su tutti gli aerei

It took place on 30 September in Brussels, at the headquarters of the European Commission on the search, the final meeting of the project "FLY-BAG2 - Advanced technologies for bombproof cargo containers and blast containment units for the retrofitting of passenger airplanes" in they collaborated, in addition to CETMA, 12 Partners from 7 different European countries, including research centers, enterprises and Italian airline Meridiana.

FLY-BAG2 was the natural continuation of the project "FLY-BAG - Blastworthy textile-based luggage containers for aviation safety", co-funded in 2009 by the European Community under the Seventh Framework Programme and inherent the development of an innovative system to be installed in the cargo hold of the aircraft for the containment of explosions in case of hidden weapons.

Starting with the excellent results achieved in 2012 with "FLY-BAG2 "it was decided to continue and extend the research activities of more containment devices, in hold versions, cabin and cargo.

the idea behind both projects was to create device in technical fabrics , properly combined with panels composite , unable to resist the different phenomena that occur during an explosion: (a) impulsive dynamic load, called 'shock-holing', which manifests itself in the first milliseconds after the event; (B) quasi-static pressure, which is generated after the phenomenon of shock-holing of the duration of a few seconds; (C) screening of any fragments caused by the presence of luggage and (d) ignition and flame propagation. In addition, the system must be as light and inexpensive as possible.

The CETMA has played a key role in both projects, having personally managed all numerical simulation activities, which are essential for proper and efficient design of different devices. In addition, it performed extensive mechanical characterization campaign, using low and high speed impact test (using "drop tower"), the technical textiles and composite panels, by identifying the best performing combinations. All the demonstrators were supported tests and compared with the results of numerical calculation activities carried out specifically from the "Modeling and Simulation" to allow proper development of numerical models of the materials.

The simulations on virtual prototypes of container allowed to study and analyze the behavior during the explosion, before the open and then inside the fuselage of the A321 and MD80-87 aircraft.

The intense and complex simulation work has enabled us to assess the contribution of the devices in terms of blast mitigation and, therefore, damage induced on the aircraft structure without resorting to numerous experimental tests, particularly expensive due to their technical complexity and the considerable security restrictions.

The final test of explosion, carried out at the airport of Cotswold, historical basis of the RAF (Royal Air Force Aerobatic Team) in Wales, confirmed the provisions by means of numerical simulations, demonstrating the effectiveness of the devices mitigation developed and the entire work done by all the project partners.

The excellent work has made it possible to file a European patent (EP2492217 A1) and the launch of numerous contacts with companies interested in acquiring such technology, hoping to soon see FLY-BAG in ordinary equipment of all aircraft in the world.
