  1. 6. How to Keep an Unbalanced Aircraft Balanced : Control Surfaces and Thrust Vectoring

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Adam Olsson; David Jacobsson; [2019]
    Nyckelord :;

    Sammanfattning : To balance and control different aircraft, it is often necessary to use some type of control system, the less stable the craft is without any control system, the more advanced the system is required to be. This project is an experiment which purpose is to attempt to control a very unstable craft using steerable rudders. LÄS MER

  2. 7. Optimal configuration of the mechanical structure and flap actuator for hydrofoils

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Stanislav Minko; [2019]
    Nyckelord :;

    Sammanfattning : Hydrofoil vessels are becoming more popular and driving marine development forward. Since the water friction is greatly reduced, they allow achieving higher speeds and electrification of the boats. FoilCart is a full electric active controlled hydrofoil boat designed as a research project at KTH. LÄS MER

  3. 8. Bärplan till 505-jolleHydrofoilHydrofoil

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Henrik Lindholm; Anders Fox; Henrik Larsson Sevon; [2019]
    Nyckelord :;

    Sammanfattning : Målet med detta kandidatexamensarbete var att studera möjligheten att använda hydrofoils på en 505-jolle. Detta gjordes genom att utforma en konceptlösning av ett hydrofoilsystem. Systemtypen som valdes för att utvärderas var ett bi-T-foliesystem. LÄS MER

  4. 9. Design Study of a Wing Rudder : Exploring the Possibility to Implement Additive Manufacturing

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :Marcus Ekman; [2017]
    Nyckelord :Additive manufacturing; Design for additive manufacturing; Aerospace industry; Design study; Engineers process aspects;

    Sammanfattning : Subtractive manufacturing are the most common methods in the aerospace industry to manufacture components. In these parts the buy to fly ratio is low and it needs accurate strengths analyses to static and dynamic loads especially were the different parts relate to each other with fasteners in the assembly work.

  5. 10. Accuracy of transient versus steady state forces on a rudder operating in a propeller slipstream

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Erik Löfgren; [2015]
    Nyckelord :Unsteady flows; rudders; propellers; fluid mechanics; performance prediction; unsteady aerofoils;

    Sammanfattning : In computational fluid dynamics (CFD), a transient simulation is in general more costly than computing the steady state of the system, if such a state exists. The velocity field produced by the propeller blades upstream of a rudder is transient in nature, and rudder design using CFD may therefore become very time-consuming. LÄS MER
