  2. 11. On Exergy and Aero Engine Applications

    Author : Oskar Thulin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Installed propulsion unit performance; Turbofan; Aero engine; Performance modelling; Exergy analysis;

    Abstract : Aero engine performance analysis is highly multidimensional using various measures of component performance such as turbomachinery and mechanical efficiencies, and pressure loss coefficients. Using conventional performance analysis, relying on only the first law of thermodynamics, it is possible to understand how the performance parameters affect the component performance, but not how the component performance relates to the system performance.

  6. 14. Recyclable self-reinforced ductile fiber composite materials for structural applications

    Author : Christof Schneider; Dan Zenkert; Sohrab Kazemahvazi; Malin Åkermo; Ignace Verpoest; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-reinforced polymer; Composite; sandwich structure; mechanical properties; impact behaviour; finite element; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Lightweight structures in vehicles are a proven way to reduce fuel consumption and the environmental impact during the use. Lower structural weight can be achieved by using high performance materials such as composites or using the material efficiently as a sandwich structure. READ MORE

  7. 15. Technical cost modelling and efficient design of lightweight composites in structural applications

    Author : Mathilda Karlsson Hagnell; Malin Åkermo; Dan Zenkert; Gerhard Ziegmann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technical cost modelling; composite materials; carbon fibre; lightweight design; optimization; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : A lightweight transport design reduces fuel costs and emissions and can be achieved through the use of fibre-reinforced composite materials. Although lightweight, the composite raw material can be expensive and the sequential component production challenging and costly. READ MORE
