  2. 11. Novel, yet similar: A similarity-assisted product family design approach for structural aero-engine components

    Author : Julian Martinsson Bonde; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design support; aerospace; similarity metrics; aero-engine structures; design space exploration; engineering design;

    Abstract : The aviation industry is in a state of transformation. The climate crisis has amplified the need to innovate, and consequently manufacturers in the aviation industry need to investigate new and more sustainable design concepts. READ MORE

  4. 12. On the Design of Functionally Integrated Aero-engine Structures: Modeling and Evaluation Methods for Architecture and Complexity

    Author : Visakha Raja; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Product Architecture; Aero-engine Structures; Configurable Components; Load Paths; Design Product Complexity; Functionally Integrated Product Architecture; Product Development; Structural Complexity; Function–Means Modeling;

    Abstract : The drive for airplanes with radically reduced fuel consumption and emissions motivates engine manufacturers to explore innovative engine designs. The novelty of such engines results in changed operating conditions, such as newly introduced constraints, increased loads or rearranged interfaces. READ MORE

  6. 14. Influence of Microstructure on Chip Formation - Machining Aero Engine Alloys

    Author : Stefan Cedergren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Superalloy; Alloy 718; Ti-6Al-4V; Inconel 718; segmented chip; shear-localization;

    Abstract : Aero engine materials such as nickel-iron and titanium based alloys are known to be very difficult to machine. They are also known to produce shear-localized chips; a type of chip which is associated with both an increase of the tool wear and the vibration levels during machining. READ MORE

  7. 15. Experimental Aero Study on Turbine Rear Structures at Engine-Realistic Flow Conditions

    Author : Valentin Vikhorev; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clean Sky 2 Joint Undertaking European Union EU Horizon 2020 CS2-RIA EATEEM 82139; Turbine Rear Structure; Hot-wire anemometry; Outlet Guide Vanes; Experimental; Particle Image Velocimetry; Turbomachinery;

    Abstract : The aviation industry has made great progress in continuous improvements that reduce the key pollutants associated with aero engines. However, high demands on the aviation industry drive manufacturers and designers to develop even more efficient aero engines. READ MORE
