  3. 2. OPTIMIZATION OF NOZZLE SETTINGS FOR A FIGHTER AIRCRAFT

    Master-uppsats, Mälardalens högskola/Industriell ekonomi och organisation

    Författare :Alexander Stenebrant; Nor Al-Mosawi; [2019]
    Nyckelord :Low-bypass turbofan; afterburner; convergent-divergent nozzle; afterbody drag; computational fluid dynamics.;

    Sammanfattning : Most fighters use the convergent-divergent nozzle configuration to accelerate into the supersonic realm. This nozzle configuration greatly increases the thrust potential of the aircraft compared to the simpler convergent nozzle. LÄS MER

  4. 3. Performance assessment of a hybrid electric-powered long-range commercial airliner

    Master-uppsats, KTH/Aerodynamik

    Författare :Thomas Zöld; [2012]
    Nyckelord :;

    Sammanfattning : Despite the recent increase in the amount of smaller electric general aviation aircrafts, a fully electric airliner is not likely to fly in the near future. Partially inspired by the automotive industry’s success with the hybrid car, this thesis investigated the feasibility of an electric-hybrid propulsion system for an Airbus A340-600 on a long-haul flight and its effect on the aircraft’s performance.
