Developed in the firm’s Edinburgh, Scotland, office through a companywide R&D initiative, JASSO allows for the safe and cost-effective testing of individual pieces of equipment and live explosive ordnance of up to 5 tonnes and 6 meters long.
Testing of ship structures and equipment against underwater shocks is a well-established practice. However, it is affected by high costs, low number of facilities and the consequences associated with failed testing. The JASSO portable shock test machine solves these issues. Named after a god of thunder, JASSO uses seismic airguns arranged in an array to simulate the explosive shock wave from an underwater explosion.
It provides a realistic, tuneable and environmentally friendly underwater dynamic shock pulse without the use of live explosives. Unlike conventional shock testing facilities, it can also be delivered and used essentially in any location. The machine was primarily developed for use in defence and security sectors, but its capabilities expand to non-standard shock testing, such as in the aerospace, transport and environmental sectors.
The Institute of Physics (IOP) is the professional body and learned society for physics, and the leading body for practising physicists, in the UK and Ireland. With a rich history of supporting business innovation and growth, it is committed to working with ‘physics-based’ businesses, and companies that apply and employ physics and physicists.
Thornton Tomasetti Principal & European Regional Leader Phillip Thompson said: “JASSO was the brainchild of three teams at Thornton Tomasetti: CORE Research and Development, Defence, and Applied Science. The patented technology removes barriers that have historically prevented effective ordnance testing, as the portable functionality offers lower costs, lower risks and higher capacity, unlike any other products on the market.”
