  1. 16. Lifting body design and CFD analysis of a novellong range pentacopter, the TILT LR drone

    University essay from KTH/Mekanik

    Author : Daniel Catagay; Haoqian Yuan; [2016]
    Keywords : Lifting body; CFD; Mesh; Multi-rotor; Drone; Aerodynamic; Simulation; y-plus; Aspect ratio;

    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 aerodynamicperformances. The configuration, which is used as the skeleton of the long range drone for upto 75 kilometers flights, is based upon a tilting system allowing the rotors to rotate around theirown axis in both pitch and roll angles.

  3. 17. Numerical modelling of deformation within accretionary prisms

    University essay from Institutionen för informationsteknologi

    Author : Ting Zhang; [2012]
    Keywords : Discrete Element Method; accretionary wedge; basal friction; compression force; area loss; displacement;

    Abstract : A two dimensional continuous numerical model based on Discrete Element Method is used to investigate the behaviour of accretionary wedges with different basal frictions. The models are based on elastic-plastic, brittle material and computational granular dynamics, and several characteristics of the influence of the basal friction are analysed. READ MORE

  4. 18. Spillage Drag Estimation and Drag-Thrust Accounting for a Missile with Air Breathing Propulsion

    University essay from KTH/Flygdynamik

    Author : Jon Olsen; [2012]
    Keywords : ;

    Abstract : Air intake related aerodynamic aspects of an air breathing cruise missile are analyzed. A method for thrust and drag accounting is established, and, based on that, a partial simulation model for the thrust and intake spillage drag force of the missile is developed. The model combines wind tunnel data with analytical data. READ MORE

  5. 19. Analysis, design and control aspects of linear machines using co-simulation

    University essay from KTH/Elektrisk energiomvandling

    Author : Muhammad Salman; [2012]
    Keywords : ;

    Abstract : This research work describes the permanent magnet linear machines, their characteristics, control and applications. It aims to develop a linear machine model in finite element based software, Flux2D. The Finte Element Method (FEM) model consists of 8 poles and 9 slots where periodicity of poles is used to simulate inifinite travel length. READ MORE

  6. 20. The performance of an iced aircraft wing

    University essay from Institutionen för ingenjörsvetenskap

    Author : Daniel Andersson; [2011]
    Keywords : Airfoil; ice layer; in-flight icing; wind tunnel; rapid prototyping; lift force;

    Abstract : The goal of this thesis work has been to develop and manufacture an ice layer which was to be mounted on the tip of a scaled down wing model. The iced wing should be tested in a wind tunnel and aerodynamic comparisons should be made to the same wing without ice.The development of the ice was carried out as a modified product development process.
