  1. 1. On aircraft fuel systems : conceptual design and modeling

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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.

    Sammanfattning : 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. LÄS MER

  5. 5. Knowledge Based Integrated Multidisciplinary Aircraft Conceptual Design

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

    Sammanfattning : 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.
