Weapons, Protection and Security

Research is the primary activity at Grindsjön. Various kinds of investigations and test activities are also conducted, in support of the Swedish Armed Forces and other commissioning organisations. Research in a wide range of fields is undertaken, from studies of physical and chemical phenomena to finding solutions in the form of complex technical systems. The ready access to shooting ranges and explosive materials-certified laboratories is a prerequisite for all the activities in which theory and experiment interact.

Test facilities

At Grindsjön, methods for designing and evaluating physical protection against military weapon effects, terrorism and sabotage are developed. The unique experimental resources available there allow everything from standardised testing to qualified studies of correlations between today’s warheads and protection technologies and those of the future. Having accessible test facilities also enables large-scale firing and explosion trials. Via model development and with the aid of modern computational and evaluation tools the results are converted into technical data to support both decision-making with regard to the vulnerability of people, buildings, and so on, and assessment of the potential of new weapons and protective techniques.

Research

Research is undertaken on explosive materials, launch and propulsion technologies, warhead technology, electromagnetic weapons and protection as well as underwater technology (hydrodynamics and underwater weapons). Core competences are propellant combustion and explosive detonations, pulsed electrical power, as well as effects on military vehicles and weapons systems. The research is based on expert knowledge of rapid deformations in solid materials, measuring techniques capable of recording such deformations, interactions between fluids, gases and solid materials, turbulence modelling, electrodynamics, combustion and plasma physics, numerical methods and computer technology.

Explosive materials programme

The explosive materials programme comprises research, development, testing, demilitarisation and small-scale fabrication of explosive materials. FOI’s competence in areas such as synthesis, formulation, analysis, characterisation and initiation of explosives, propellants and pyrotechnics has all been brought together in Grindsjön. Development in space applications and anti-terrorism is also underway. Also conducted here are classification and functional testing of explosive materials, risk analysis associated with inflammable and explosive materials as well as education and training within the field of explosive materials.

Security of explosives

Tests of the security and safety of ammunition are carried out through, among other things, missile engine testing, and stability and aging studies.
