  1. 1. Design Automation of Air Intake Lips on an Aircraft : How to implement design automation for air intake lips in a later design concept phase

    Master-uppsats, Linköpings universitet/Produktrealisering

    Författare :Wilma Blixt; Hilda Schönning; [2023]
    Nyckelord :Design Automation; Imagine and Shape; Subdivided surface; 3DExperience; CATIA; Air intake; MOKA; Knowledge Based Engineering;

    Sammanfattning : Air intakes are complex components that are critical for the propulsion of the aircraft. The design has to consider requirements from several different departments, often contradictory. Additionally, the air intakes need to cooperate with other critical components. This makes testing of the models crucial, hence time-demanding. LÄS MER

  3. 2. Conceptual Design of an Ekranoplan UAV

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

    Författare :Sheng-An Yu; [2022]
    Nyckelord :Ekranoplan; Unmanned ground effect vehicle UGEV ; vertical take-off and landing VTOL ; aircraft design; Ekranoplan; Obemannad markeffektfarkost UGEV ; Vertikal Start och Landning VTOL ; Flygplansdesign;

    Sammanfattning : Unmanned aerial system (UAS) has developed into an important platform of high-altitude photography, which can be applied in animal studies, pollution forensics and geographic monitoring. This thesis work aims to design a unmanned ground effect vehicle (UGEV) in order to provide a much better and flexible solution to future applications. LÄS MER

  4. 3. En kvalitativ studie av laserskanning med drönare

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Johan Andersson; [2022]
    Nyckelord :drönare; laserskanning; mervärde;

    Sammanfattning : Fjärranalys och nyttjandet av olika sensorer har under det senaste decenniet fått allt större betydelse inom skogsbruket (Nordkvist & Olsson 2012). Bland annat genomför Lantmäteriet löpande en rikstäckande laserskanning med flyg. Den data som samlas in finns tillgänglig för allmänheten och används bland annat för skogliga syften. LÄS MER

  5. 4. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Sergi Tarroc Gil; [2021]
    Nyckelord :Zonal Model; Thermal Comfort; Fluid Simulation; Aircraft Cabin Design; NURBS; Morphing; Radial Basis Functions; Meshing; Co-located Mesh; Unstructured Mesh; Mesh Quality; Mesh Smoothing; Enlarged Orientation Theorem; Fractional Step Method; Boussinesq; Adam Bashforth; Helmholtz-Hodge Theorem; Rhie and Chow; Difference Schemes; Gradient Evaluation; Differential Heated Cavity; Driven Cavity; Draught Rate;

    Sammanfattning : The simulation of physical systems in the early stages of conceptual designs has shown to be a key factor for adequate decision making and avoiding big and expensive issues downstream in engineering projects. In the case of aircraft cabin design, taking into account the thermal comfort of the passengers as well as the proper air circulation and renovation can make this difference. LÄS MER

  7. 5. Utformning avlandningsbanors överbyggnad med hänsyn till slitlagrets bärförmåga

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Ali Al-anbagi; Dani Khalil; [2020]
    Nyckelord :Slitlager; Dimensionering; Landningsbana; Flygfält; Överbyggnad;

    Sammanfattning : n this study, the design of the runway structure of the runways is studied in order tocompare different material compositions in the pavement. This is done with the helpof a survey, the program FAARFIELD and peer reviewed studies. Generally, thereare two different types of road structures in an airfield, rigid and flexible (concreteand asphalt). LÄS MER
