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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Peter Sturesson; Uppsala universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

    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 automated conceptual design space exploration

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Jakob Müller; [2018]
    Keywords : HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Design; Model Abstraction; Function Modelling; Knowledge Based Engineering; Model Based Design; Function-Means Modelling; Geometry Modelling; Design Space Exploration; Product Development; Systems Engineering; Design Automation; Aerospace;

    Abstract : In mature and safety-concerned industries, such as the aerospace industry, product development is often incremental and design solutions are limited to improvements of an existing design. Radical changes to the known product architecture are avoided, for reasons of reliability, lack of technology or lack of design space exploration (DSE) methods. READ MORE

  3. 3. Compressive failure of unidirectional NCF composites

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Dennis Wilhelmsson; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace; Fibre misalignment; Compressive failure; NCF composite;

    Abstract : With more people flying every year, new technologies are needed to reduce our impact on the environment. One option is to reduce the energy used in flight by introducing lighter materials such as carbon fibre reinforced polymers (CFRP). READ MORE

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Per Hallander; KTH.; [2016]
    Keywords : 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

  5. 5. Uncertainty and Robustness in Aerospace Structures

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Anders Forslund; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; uncertainty quantification; geometry assurance; simulation; robust design; Geometrical variation;

    Abstract : Engineering is not an exact science. In fact, all engineering activity contain some degree of assumption, simplification, idealization, and abstraction. When engineered creations meet reality, every manufactured product behaves differently. This variation can be detrimental to product quality and functionality. READ MORE
