In a series of controlled explosions, scientists tested a bomb proof lining technology to avoid explosions in aircrafts, which showed positive results.
Developed by an international team of scientists, including academics from the University of Sheffield, the Fly-Bag lining technology, successfully contained blasts in a series of controlled explosions in the luggage hold of a Boeing 747 and an Airbus 321.
The technology which lines an aircraft's luggage hold with multiple layers of novel fabrics and composites, was tested under increasing explosive charges on disused planes at Cotswolds Airport, near Cirencester, this week.
Fundamental to the design of the bag is a combination of fabrics which have high strength and impact and heat resistance. The fabrics include Aramid, which is used in ballistic body armour.
Lead researcher Dr Andy Tyas at the University of Sheffield said that the key to the concept was that the lining was flexible which added to its resilience when containing the explosive force and any fragments produced. It helped to ensure that the Fly-Bag acted as a membrane rather than as a rigid-walled container which might shatter on impact.
Hardened luggage containers (HULD) have been developed to deal with bombs hidden in passenger luggage, but these containers are heavier and more costly than conventional equivalents.
A European consortium working on the Fly Bag project includes Blastech, a spin out company from the University of Sheffield, as well as partners from Greece, Spain, Italy, Germany, Sweden and the Netherlands.
