  1. 1. CFD Optimization of Hydrofoiling Concept for A New Era of Sea Transports

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Anlun Li; [2022]
    Nyckelord :Optimization; Hydrofoil; FoilCart; Transportation; CFD; Optimering; Hydrofoil; FoilCart; Transport; CFD;

    Sammanfattning : The aim of this master thesis is to develop and optimize the main wing of a T-shaped hydrofoil for a small passenger vessel called FoilCart. The project is in collaboration with KTH Maritime Robotic Lab. The existing prototype of the hydrofoil is built by a company called ZPARQ\cite{Zparq}, but the efficiency of the main wing is not optimized. LÄS MER

  3. 2. Linear and non-linear FE-analysis of cracking behavior of wing walls in integral bridges

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Andreas Ekman; Christoffer Sandin; [2018]
    Nyckelord :Non linear FE-modelling; Concrete Damage Plasticity; Wing wall; Crack propagation; Serviceability Limit State; Slab Frame Bridge; Technology and Engineering;

    Sammanfattning : Wing walls on slab frame integral bridges has traditionally been designed for mainly earth pressure and its self-weight. It has also been designed separately from the rest of the bridge. Traditionally no 3D effects have been considered in the design of the wing walls. LÄS MER

  4. 3. Study of tip clearance flows

    Master-uppsats, KTH/Flygdynamik

    Författare :Camille Fournis; [2018]
    Nyckelord :turbomachine; compressor; tip leakage flow; vortex; turbomaskin; kompressor; gapflöde; virvel;

    Sammanfattning : The tip leakage vortex is responsible for the generation of stagnation pressure losses inside the compressor along with the outbreak of rotating stall and surge. The current paper analytically proved that a part of the losses is proportional to the vortex circulation squared. LÄS MER

  5. 4. Development of a Framework for Concept Selection and Design Automation : Utilizing hybrid modeling for indirect parametric control of subdivision surfaces

    Master-uppsats, Linköpings universitet/Maskinkonstruktion

    Författare :Adam Eklund; Jesper Karner; [2017]
    Nyckelord :Design Automation; Imagine and Shape; Aircraft Conceptual Design; Computer Aided Design; Knowledge-Based Engineering; Interactive Reconfigurable Matrix of Alternatives; Concept Selection; CAD;

    Sammanfattning : Saab Aeronautics’ section Overall Design and Survivability develops early aircraft concepts and utilizes Computer Aided Design (CAD) to ensure the feasibility of principal- and critical characteristics. Saab has over the years developed several start models of aircrafts in CAD from pre-defined aircraft configurations, which are to some extent non-generic. LÄS MER

  7. 5. Design and Analysis of the Controland Stability of a Blended WingBody Aircraft

    Master-uppsats, KTH/Aerodynamik

    Författare :Roberto Merino Martínez; [2014]
    Nyckelord :;

    Sammanfattning : Future aircraft generations are required to have higher performance and capacities. This achievement should be fulfilled with the minimum cost and environmental impact. LÄS MER
