  2. 16. On Subscale Flight Testing : Applications in Aircraft Conceptual Design

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

    Abstract : 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.

  4. 17. On subscale flight testing : Cost-effective techniques for research and development

    Author : Alejandro Sobrón Rueda; Petter Krus; David Lundström; Mirko Hornung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Experiments with downscaled or subscale physical models have traditionally been an essential source of information in aerospace research and development. Physical models are very effective at revealing unforeseen issues and providing confidence in design predictions or hypotheses. READ MORE

  5. 18. The flight perturbation problem : operational aircraft rescheduling

    Author : Tobias Andersson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : When there is a perturbation in a carefully planned flight schedule, e.g. an aircraft breakdown, it is important to minimize the negative consequences of this disturbance. In this thesis, a model and a number of solution strategies for the Flight Perturbation Problem is presented. READ MORE

  6. 19. Power and Wake Dynamics of Hawkmoth Flight

    Author : Kajsa Warfvinge; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insect flight; Aerodynamics; Wind tunnel; Particle Image Velocimetry PIV .; tomo-PIV; Power; Manduca sexta; Macroglossum stellatarum; Hawkmoth;

    Abstract : Aerodynamic theory states that the power required to fly is related to flight speed with a ∪-shaped curve. This has been shown in vertebrates, but insects have been proposed to have a flat, or J-shaped power curve. READ MORE
