    Sammanfattning : Denna rapport beskriver ett examensarbete inom integrerad produktutveckling vid Högskolan i Skövde. Arbetet utfördes i samarbete med företaget The Best of Sweden AB där uppdraget var att utveckla ett fäste och skyltar för bakrutetorkare på personbilar. LÄS MER

  2. 2. Supersonic Retro Propulsion Flight Vehicle Engineering of a Human Mission to Mars

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Hanna Marklund; [2019]
    Nyckelord :Supersonic retro propulsion; SRP; Mars; Human mission; Inflatable heat shield;

    Sammanfattning : A manned Mars mission will require a substantial increase in landed mass compared to previous robotic missions, beyond the capabilities of current Entry Descent and Landing, EDL, technologies, such as blunt-body aeroshells and supersonic disk-gap-band parachutes. The heaviest payload successfully landed on Mars to date is the Mars Science Laboratory which delivered the Curiosity rover with an approximate mass of 900 kg. LÄS MER

  3. 3. A study on Friction Boundary Conditions with Unicorn/FEniCS-HPC

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Irene Natale; [2019]
    Nyckelord :;

    Sammanfattning : The aim of this thesis is to present and validate a boundary condition formulation for CFD problems that includes a friction parameter. In the first part of the thesis the incompressible Navier-Stokes system of equations and the friction boundary conditions are presented. LÄS MER

  4. 4. Enabling high-fidelity measurements of turbulent boundary layer flow over wing sections in the MTL wind tunnel.

    Master-uppsats, KTH/Mekanik

    Författare :Fermin Mallor; [2019]
    Nyckelord :Fluid mechanics; aerodynamics; turbulence; RANS; wind-tunnel experiments; insert design; Strömningsmekanik; aerodynamik; turbulens; RANS; vindtunnel experiment; inlaga designen;

    Sammanfattning : A reinforced fiber-glass model of a NACA 4412 wing profile is designed and set-up in the Minimum Turbulence Level (MTL) wind tunnel facility at KTH. The model has 65 pressure taps orifices, and the set-up includes two mounting panels designed to allow for particle image velocimetry (PIV) and hot wire anemometry (HWA) measurements of the boundary layer (to be performed in a future campaign).

  5. 5. Loosely coupled, modular framework for linear static aeroelastic analyses

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Aaron Dettmann; [2019]
    Nyckelord :Aeroelasticity; Simulation; CFD; FEM; VLM; Euler-Bernoulli beam theory III; Aeroelasticitet; Simulation; CFD; FEM; VLM; Euler-Bernoulli-balkmodell;

    Sammanfattning : A computational framework for linear static aeroelastic analyses is presented. The overall aeroelasticity model is applicable to conceptual aircraft design studies and other low-fidelity aero-structural analyses. A partitioned approach is used, i. e. LÄS MER
