  2. 2. Affordable automation for airframe assembly : developing of key enabling technologies

    University dissertation from Gothenburg

    Author : Henrik Kihlman; Mats Björkman; Giorgos Nikoleris; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Building aircraft is a challenging field. An aircraft has a life expectancy of 40 years, compared to just 10 years for a car. Given the vibrations of flying at close to Mach one at an altitude of 10,000 meters, these machines must function flawlessly in a tough environment. This demands high quality in the assembly processes. READ MORE

  3. 3. Cost Optimization of Aircraft Structures

    University dissertation from Gothenburg

    Author : Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Abstract : 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. READ MORE

  4. 4. Turbulence-resolving simulations for engineering applications

    University dissertation from Gothenburg

    Author : Bastian Nebenführ; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; Aeroacoustics; Forest canopy; Airframe noise; hybrid RANS LES; Turbulence-resolving simulation; Wind-turbine fatigue loads; Wind power;

    Abstract : Most fluid flows of industrial interest are turbulent and their accurate representation may be of vital importance for the design process of new products. To date, steady RANS methods are usually employed for the simulation of turbulent flows of everyday engineering problems. READ MORE

  5. 5. Static and Fatigue Failure of Bolted Joints in Hybrid Composite-Aluminium Aircraft Structures

    University dissertation from Linköping University Electronic Press

    Author : Zlatan Kapidzic; Hans Ansell; Kjell Simonsson; Larsgunnar Nilsson; Michael Wisnom; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid structures; Composites; Bearing failure; Bolted joints;

    Abstract : The use of fibre composites in the design of load carrying aircraft structures has been increasing over the last few decades. At the same time, aluminium alloys are still present in many structural parts, which has led to an increase of the number of hybrid composite-aluminium structures. READ MORE
