  1. 21. Lifting body design and CFD analysis of a novel long range pentacopter, the TILT LR drone

    University essay from KTH/Mekanik

    Author : Daniel Cagatay; Haoqian Yuan; [2016]
    Keywords : Lifting body; CFD; Mesh; Multi-rotor; Drone; Aerodynamic; Simulation;

    Abstract : In the thesis, a lifting body has been designed aiming to generate lift force for the pentacopter, called TILT LR (Long Range), at higher velocities during flights to improve the aerodynamic performances. The configuration, which is used as the skeleton of the long range drone for up to 75 kilometers flights, is based upon a tilting system allowing the rotors to rotate around their own axis in both pitch and roll angles.

  5. 24. Exploitation of Digital Surface Models from Optical Satellites for the Identification of Buildings in High Resolution SAR Imagery

    University essay from KTH/Geoinformatik

    Author : Rebecca Ilehag; [2016]
    Keywords : SAR; DSM; GeoRaySAR; nDSM; building detection;

    Abstract : Interpreting a Synthetic Aperture Radar (SAR) image and detecting buildings can be a difficult task visually. In order acquire an overview of an area that has been affected by a disaster, such as an earthquake, SAR is useful due to its independence of weather conditions and the time of the day. READ MORE
