  1. 6. μSPL - Proprietary Graphics Language Transpiler : Asserting translation correctness using runtime verification

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Henrik Andersson Glass; [2021]
    Nyckelord :Cockpit Display System; Compiler Correctness; Compiler; Transpiler; Computer Graphics; Cockpitpresentationssystem; Kompilatorkorrekthet; Kompilator; Transpilator; Datorgrafik;

    Sammanfattning : The Swedish Armed Forces are currently considering extending the operational life of the Saab JAS 39 Gripen C/D multirole fighter aircraft by an additional 10 to 20 years. This has resulted in a need to upgrade many of the hardware components originally developed in the late 1980s and early 1990s. LÄS MER

  3. 7. Conceptual Design of an Air-Launched Three-Staged Orbital Launch Vehicle

    Master-uppsats, KTH/Rymdteknik

    Författare :Måns Rasmussen; [2021]
    Nyckelord :Air-launched; Launch Vehicle; Three-staged; Rocket; Sun-Synchronous orbit; Solid propellant; Liquid propellant; Trajectory optimization; Nonlinear programming; JAS 39 Gripen; Fighter aircraft; Luftlanserad; Trestegsraket; Solsynkron bana; Fast bränsle; Flytande bränsle; Bananalys; Icke-linjär optimering; JAS 39 Gripen; Jaktflygplan;

    Sammanfattning : The objective of this study was to design a launch vehicle capable of deploying a nanosatellite into a Sun-synchronous orbit at 500 km orbital altitude from the JAS 39E/F Gripen fighter aircraft. This was achieved by first performing theoretical calculations for the required nozzles and solid propellant grain configurations for the first two solid stages, followed by the necessary liquid propellant configuration for the third stage.

  4. 8. Aeroelastic flutter analysis with varying level of accuracy

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Nils Voigt Dahl; [2020]
    Nyckelord :flutter; aeroelasticity; aeroelastic; aerodynamics; Technology and Engineering;

    Sammanfattning : Flutter prediction is a vital part of aircraft development which requires efficient and accurate analysis methods. Saab AB Aeronautics is currently using linear analysis based on the panel method and nonlinear analysis using their in-house CFD software program. These methods are in contrast to one another in terms of computing time and accuracy. LÄS MER

  5. 9. Predictive Maintenance for RM12 with Machine Learning

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Lotta Karlsson; [2020]
    Nyckelord :;

    Sammanfattning : Few components within mechanical engineering possess the fatigue resistance as of high-pressure turbine blades found in jet engines. This as they are designed to perform in extensively high temperatures under severe loading which causes degradation to be an important aspect despite a design, optimized for its environment. LÄS MER

  7. 10. Influence of Design Parameter Variation on Fighter Agility Metrics

    Master-uppsats, KTH/Flygdynamik

    Författare :Albin Karlsson; [2020]
    Nyckelord :;

    Sammanfattning : Metrics that quantify fighter aircraft performance is an active research topic, and agility metrics seek to measure performance previously not captured with classic point performance metrics. Agility metrics are researched to be used in analysis with an advanced desktop simulator and investigate the effects of design parameter variation. LÄS MER
