  1. 11. Variability and Customization of Simulator Products : A Product Line Approach in Model Based Systems Engineering

    Author : Henric Andersson; Petter Krus; Johan Ölvander; Lars Hvam; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Abstract : AIRCRAFT DEVELOPERS, like other organizations within development and manufacturing, are experiencing increasing complexity in their products and growing competition in the global market. Products are built from increasingly advanced technologies and their mechanical, electronic, and software parts grow in number and become more interconnected. READ MORE

  2. 12. Ideals and Interests in Swedish Foreign Policy : Explaining the South African Gripen Deal

    Author : Wayne Stephen Coetzee; Isabell Schierenbeck; Jan Aart Scholte; Douglas Brommesson; Högskolan Väst; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Foreign Policy; Ideals; Interests; Arms Trade; Gripen; Sweden; South Africa; Political science; Statsvetenskap;

    Abstract : This dissertation explores ideals and interests (and their interrelation) in foreign policy. An in-depth case study of this issue examines Sweden’s 1999 JAS-39 Gripen fighter aircraft deal with South Africa. READ MORE

  3. 13. Iterative solution of Maxwell's equations in frequency domain

    Author : Martin Nilsson; Per Lötstedt; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Abstract : We have developed an iterative solver for the Moment Method. It computes a matrix–vector product with the multilevel Fast Multipole Method, which makes the method scale with the number of unknowns. The iterative solver is of Block Quasi-Minimum Residual type and can handle several right-hand sides at once. READ MORE

  4. 14. Flight Test System Identification

    Author : Roger Larsson; Martin Enqvist; Lennart Ljung; Roy Smith; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With the demand for more advanced fighter aircraft, relying on unstable flight mechanical characteristics to gain flight performance, more focus has been put on model-based system engineering to help with the design work. The flight control system design is one important part that relies on this modeling. READ MORE

  5. 15. Realistic simulations of delta wing aerodynamics using novel CFD methods

    Author : Stefan Görtz; Arthur Rizzi; Miguel Visbal; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; CFD; aerodynamics; flow physics; steady; unsteady; delta wing; vortical flow; Rymd- och plasmafysik; Space physics; Rymdfysik;

    Abstract : The overall goal of the research presented in this thesis is to extend the physical understanding of the unsteady external aerodynamics associated with highly maneuverable delta-wing aircraft by using and developing novel, more efficient computational fluid dynamics (CFD) tools. More specific, the main purpose is to simulate and better understand the basic fluid phenomena, such as vortex breakdown, that limit the performance of delta-wing aircraft. READ MORE
