Programmes\/ Activities<\/strong><\/h3>\nAeronautics-related research can be found in most of FOI\u2019s Research Divisions, but with focus in two Departments; The Aeronautics and Autonomous Systems and the Systems Technology Department. Advanced training of Gripen pilots is another FOI core area with the operation of the Swedish Air Force Combat Simulation Centre (FLSC). It is a world-leading simulation facility for manned air combat, many-to-many, combining both manned simulators and computer generated forces (CGF). The Aeronautics and Autonomous Systems department upholds basic disciplines such as aerodynamics, structures and signatures. Research is based on numerical simulations with decades of experience in advanced methodology. The System Technology department maintains and develop the simulation models used in FLSC, but also provides research on new methods and models for system-of-system effectiveness.<\/p>\n
The aeronautical research at FOI was restructured in 2015 into a system and air combat assessment focus. These new research areas have been added to the previous platform, threat analysis and survivability with countermeasures domains. Method development remains a strong and important part of the aeronautical research at FOI together with academia and industrial partners within Sweden.<\/p>\n
FOI maintains and builds aeronautical competence within the following groups:<\/p>\n
Aerodynamics<\/strong><\/p>\nConceptual design and performance assessment of manned and unmanned vehicles including weapon and missiles provides aero data for simulation models. A range of numerical in-house tools, from basic panel methods to state-of-the-art CFD software including meshing are maintained to the highest standard. Incorporating unique capability for flow control, aero-elasticity, store separation, propulsion integration and countermeasure aerodynamics.<\/p>\n
Structures and materials<\/strong><\/p>\nLarge-scale structural design and analysis of aircraft to predict static strength, fatigue life and damage tolerance of real aircraft structures made from both metallic and composite materials. A variety of commercial and in-house numerical tools. Expertize in high performance computing (HPC) to scale efficiently up to many thousand cores and sustained Tera-FLOP speed. Crack growth and failure analysis with experience of accident investigations of aircraft and industrial applications.<\/p>\n
Signatures<\/strong><\/p>\nMultidisciplinary RCS and IR signature predictions for detection and (NCTI) identification using in-house and commercial software for full scale analysis including specular and diffuse reflections, cavities and RAM\/RAS material characterization and with background modelling.<\/p>\n
Flight dynamics<\/strong><\/p>\nStability, control and non-linear concepts from fighter jets, including pilot input, down to fine caliber munition. With unconventional actuation using MEMS, plasma, micro-jets or morphing. Mission planning and combat performance metrics.<\/p>\n
Environmental impact<\/strong><\/p>\nEmission estimation of both commercial and military air transport including ATM using statistical or databased methods. Provide knowledge of regulations both on national and international levels.<\/p>\n
Combat analysis and assessment<\/strong><\/p>\nEvaluation of weapon systems at combat and tactical level for land, naval and air\/space domain using computer based simulation framework, such as surface to air missiles for national air defence, air to air missiles, air or surface to surface missiles for land and naval targets, counter rockets and mortar systems, and missile defence systems. Aggregation of multiple levels system-of-systems for scenario evaluation and materiel acquisition purposes.<\/p>\n
Guided weapons<\/strong><\/p>\nUphold expertise in guidance, navigation and control of autonomous and unmanned systems. Means of delivery for weapons, damage tolerance and vulnerability of warheads and propulsion techniques with models of varying fidelity.<\/p>\n
Simulation tool development<\/strong><\/p>\nModelling, software architecture and development of real time simulation systems for FLSC as well as planning and mission tools for pilots. Tactical behaviour modelling of CGF for training and evaluation.<\/p>\n
Space for Defence & Security<\/strong><\/p>\nProvides and builds knowledge within orbital mechanics, satellite technology with insight into the military possibilities and practical use for space technology, global growth and trends in the space sector including global security, political and policy developments. Responsibilities of arms control issues in space.<\/p>\n
Sensors and EW systems<\/strong><\/p>\nEvaluate, demonstrate and develop new or increased sensor capability in the fields of radar, IR and optics with advanced image and signal processing including data fusion and counter measure.<\/p>\n
