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. On aircraft fuel systems : conceptual design and modeling

   Author : Hampus Gavel; Petter Krus; Johan Ölvander (Andersson); Dieter Scholz; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft; morphological matrix; simulation; Saab; Gripen; Construction engineering; Konstruktionsteknik;

   Abstract : The largest and most important fluid system in an aircraft is the fuel system. Obviously, future aircraft projects involve the design of fuel system to some degree. In this project design methodologies for aircraft fuel systems are studied, with the aim to shortening the system development time. READ MORE
