  1. 1. Sense, Actuate and Survive : Ceramic Microsystems for High-Temperature Aerospace Applications

    Author : Peter Sturesson; Greger Thornell; Lena Klintberg; Peter Bull; Pelle Rangsten; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High temperature; ceramics; microsystems; aerospace; sensors; thrusters; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology; high temperature; Försvarssystem; Military Technology;

    Abstract : In aerospace applications, but also in manufacturing, mining, energy industry and natural hazards, high temperature, corrosion, erosion and radiation, challenge the performance and being of hardware.In this work, high-temperature co-fired ceramic (HTCC) alumina and platinum have been used for a range of devices intended for aerospace applications at up to 1000°C.

  2. 2. Towards defect free forming of multi-stacked composite aerospace components using tailored interlayer properties

    Author : Per Hallander; Malin Åkermo; Pascal Hubert; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Fibre; Composites; Prepreg; Forming; Aerospace Engineering; Flyg- och rymdteknik;

    Abstract : Use of lightweight materials is an important part of reduction of fuel consumption by commercial aircraft. A considerable number of structural aircraft parts are therefore built of thin layers of epoxy pre-impregnated carbon fibres stacked to laminates. READ MORE

  3. 3. Knowledge maturity as decision support in stage-gate product development : a case from the aerospace industry

    Author : Christian Johansson; Andreas Larsson; Marco Bertoni; Dave Randall; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knowledge Maturity; Knowledge Management; Stage-Gate; Decision Support; Product Development; Product-Service Systems; Aerospace; Funktionella produkter; Functional Product Development;

    Abstract : In today’s fast-paced industry where fight for market share is fierce and reaching the market ahead of competition imperative, product development is a target for lead-time reductions. In this context, in product development in stage-gate processes, decisions need to be made even though knowledge and information are scarce and flawed. READ MORE

  4. 4. Improving Forming of Aerospace Composite Components through Process Modelling

    Author : Jens Sjölander; Malin Åkermo; Per Hallander; Tonny Nyman; Göran Fernlund; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In the aerospace industry there is a constant effort to reduce the weight of aircraft. Since weight reduction has a direct impact on fuel consumption. Reducing the fuel consumption leads to botheconomical benefits through less money spent on fuel and environmental benefits through reduced CO2 emissions. READ MORE

  5. 5. Contributions to Variable Fidelity MDO Framework for Collaborative and Integrated Aircraft Design

    Author : Zhang Mengmeng; Arthur Rizzi; Leifsson Leifur; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace Engineering; Flyg- och rymdteknik;

    Abstract : The thesis develops computational tools for early stages of the aircraft design process. The work focuses on a framework which allows several design teams concurrently to develop a baseline concept into a configuration which meets requirements and whose aerodynamics has been assessed by flight simulation.
