FOI engages in research covering launch and propulsion technology, warhead technology focusing mainly on their explosive effect, high-power microwave (HPM) electromagnetic warheads and underwater technology (hydrodynamics, signatures, weapons and protection). The scientific work makes use of the development of theoretical and numerical models supported by broadly based experimental activities.
The research into warheads and propulsion systems, which are fundamental components of weapon systems, provides the Swedish Armed Forces with tools for the assessment of how new technology can be applied in future weapon systems. Among FOI’s essential areas of competence are propellant combustion, explosive detonations and pulsed electrical power, as well as effects on, and flow round, military vehicles and weapon systems. These activities have access to unique experimental facilities and well developed trials methods. 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.
FOI’s assignments come largely from the Swedish Armed Forces and the Swedish Defence Materiel Administration but also from civil authorities such as the Swedish Space Corporation and the Swedish Radiation Safety Authority. FOI has a broad range of collaborative arrangements with Universities, Colleges and other research organisations both in Sweden and internationally.
