2. 1. Aircraft Systems Modeling : Model Based Systems Engineering in Avionics Design and Aircraft Simulation

   Author : Henric Andersson; Petter Krus; Olof Johansson; Fredrik Berglund; Linköpings universitet; []
   Keywords : MBSE; MBD; Avionics; Simulation; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Aircraft developers like other development and manufacturing companies, are experiencing increasing complexity in their products and growing competition in the global market. One way to confront the challenges is to make the development process more efficient and to shorten time to market for new products/variants by using design and development methods based on models.

4. 2. Aircraft composites and aeroelastic tailoring

   Author : Jakob Kuttenkeuler; KTH; []
   Keywords : polymer composites; testing; resin; transfer molding; RTM; process parameters; mechanical properties; aircraft; impact damage; BVID; modal; inverse method; uncertainties; aeroelasticity; optimization; wind tunnel; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis treats various aspects of structural polymercomposites in aircraft applications. The mechanical performanceand quality of resin transfer molded (RTM) carbon fiberreinforced epoxy composites is studied. READ MORE

5. 3. Knowledge Based Integrated Multidisciplinary Aircraft Conceptual Design

   Author : Venkata Raghu Chaitanya Munjulury; Petter Krus; Roland Stolt; Linköpings universitet; []
   Keywords : Knowledge-base; Aircraft; Conceptual Design; CAD; XML Database; Multidisciplinary; Optimization;

   Abstract : With the ever growing complexity of aircrafts, new tools and eventually methods to use these tools are needed in aircraft conceptual design. To reduce the development cost, an enhancement in the conceptual design is needed.This thesis presents a knowledge-based aircraft geometry design tool RAPID and the methodology applied in realizing the design.

6. 4. Fighter Aircraft Maneuver Limiting Using MPC : Theory and Application

   Author : Daniel Simon; Johan Löfberg; Torkel Glad; Jan Maciejowski; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model predictive control; flight control;

   Abstract : Flight control design for modern fighter aircraft is a challenging task. Aircraft are dynamical systems, which naturally contain a variety of constraints and nonlinearities such as, e.g., maximum permissible load factor, angle of attack and control surface deflections. READ MORE

7. 5. A few aspects of aircraft noise

   Author : Crispin Dickson; Shafiquzzaman Khan; Mendel Kleiner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paired comparison; sorting based paired comparison; sorting algorithms; mergesort; quicksort; aircraft sound synthesis; aircraft noise; sound quality; tonal effects; angle positions; flight conditions; methods of equalization; cognition; Acoustics; Akustik;

   Abstract : A few aspects of aircraft noise were evaluated. These were (i) methods of subjective evaluations, (ii) effects of equalization and (iii) the effects of cognitive aspects.In the first paper, sorting algorithms were used instead of conventional paired comparison method in order to reduce the number of pairs in the evaluation of subjective judgments.
