  1. 1. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Björn Jarfors; [2023]
    Nyckelord :Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Sammanfattning : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. LÄS MER

  3. 2. Dynamic response of damped attachments in fighter applications

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

    Författare :Katja Nordström; [2023]
    Nyckelord :Vibration isolator; printed circuit board; vibrations; natural frequency; Vibrationsisolator; kretskort; vibrationer; resonansfrekvenser;

    Sammanfattning : This thesis investigates the impact of vibration isolators on circuit boards during harsh vibrationenvironments that occur when they are mounted on the wings of a fighter jet. To examine thisphenomenon, a mathematical model and a simulated model were developed to determine theresonant frequencies of the circuit board under various boundary conditions. LÄS MER

  4. 3. Development of a Rule Based Decision Support System for Pilots : Using Network Analysis, Label Propagation and Association Rule Mining

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Joel Henneberg; [2023]
    Nyckelord :;

    Sammanfattning : Maneuvering a fighter jet is not easy, and new methods for minimizing the risk of pilots experiencing information overload are constantly under development. Saab is currently looking into the possibilities of creating a decision support system (DSS) for pilots in situations where multiple independent system failures occur simultaneously. LÄS MER

  5. 4. Politics in the Skies - A Qualitative Analysis of Global Jet Fighter Sales and the Struggles of Sweden's Gripen, compared with offers from France and the United States

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för marknadsföring och strategi; Handelshögskolan i Stockholm/Institutionen för företagande och ledning

    Författare :Anders Grandien; Carl-Johan Lindström; [2023]
    Nyckelord :Procurement; Fighter Jet; Offset-agreements; Corruption; Geopolitics;

    Sammanfattning : The complex dynamics of the worldwide jet fighter market are examined in this paper, with a special emphasis on the factors that influence procurement choices and Sweden's disproportionate representation in corruption cases. Our research reveals a market environment dominated by geopolitical power, financial incentives, and superior products. LÄS MER

  7. 5. Risk of fragment hit on aircraft after releasing a bomb

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

    Författare :Hedberg Joakim; [2022]
    Nyckelord :Flightmechanics; probability; aerodynamics; Flygmekanik; sannolikhet; aerodynamik;

    Sammanfattning : An aircraft is exposed for a certain risk during warhead deployment. If the distance is too short between the aircraftand warhead during burst, fragments may hit the aircraft with fatal consequences. The warhead consists not onlyof fragments created during burst but also parts to attach it to the aircraft such as mounting plates and fasteningloops. LÄS MER
