1. 16. On aircraft fuel system design : concept evaluation and system modeling

   Författare :Hampus Gavel; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : THE LARGEST AND most important fluid system in an aircraft is the fuel system. Obviously, future aircraft projects involve the design of fuel system to some degree. In this project design methodologies for aircraft fuel systems are studied, with the aim to shortening the system development time. LÄS MER

4. 18. Capturing Value in Conceptual PSS Design : Perspectives from the Automotive Supply Chain

   Författare :Massimo Panarotto; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Design; Product Development; Conceptual Design Phases; Product-Service Systems; Business Model Innovation; Simulation Driven Design; Value Assessment;

   Sammanfattning : Manufacturing companies have traditionally focused their design and development activities on realizing technical and engineered aspects of physical artifacts based on performance requirements. The ever-changing business climate, with its increased pace during the past decades, has forced industries to continuously innovate their approach toward the development of new products. LÄS MER

5. 19. On Subscale Flight Testing : Applications in Aircraft Conceptual Design

   Författare :Alejandro Sobron; Petter Krus; David Lundström; Zdobyslaw Goraj; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Downscaled physical models, also referred to as subscale models, have played an essential role in the investigation of the complex physics of flight until the recent disruption of numerical simulation. Despite the fact that improvements in computational methods are slowly pushing experimental techniques towards a secondary role as verification or calibration tools, real-world testing of physical prototypes still provides an unmatched confidence.

7. 20. Cost Optimization of Aircraft Structures

   Författare :Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; Vehicle engineering; Farkostteknik;

   Sammanfattning : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. LÄS MER
