2. 1. 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

4. 2. 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

5. 3. Optimization of Geometric Robustness of Aero Structures in Early Design Phases

   Author : Anders Forslund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometry Assurance; Uncertainty Quantification; Robust Design; Simulation; Geometric Variation;

   Abstract : Every manufactured product is different. This variation can be detrimental to quality and product functionality. In an aerospace context, this variation may even result in serious threats to the safety and reliability of aircraft. However, it is not the variation itself that is harmful, but the effects it has on functionality. READ MORE

6. 4. Modelling of Forming and Welding in Alloy 718

   Author : Lluís Pérez Caro; Mats Oldenburg; Eva-Lis Odenberger; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forming; welding; Alloy 718; damage; GISSMO; failure; Hållfasthetslära; Solid Mechanics;

   Abstract : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry due to major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the vehicle’s weight while increasing engine's efficiency. READ MORE

7. 5. On matrix-driven failure in unidirectional NCF composites - A theoretical and experimental study

   Author : Dennis Wilhelmsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NCF composite; aerospace; compressive testing; compressive failure;

   Abstract : With ever increasing traffic levels, the civil aircraft industry is in constant need of new technologies to make air travel environmentally sustainable. One such technology is light materials to reduce the energy consumption in flight. READ MORE
