  1. 6. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Erik Axelsson; Sebastian Fagerstedt; [2023]
    Nyckelord :Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Sammanfattning : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. LÄS MER

  3. 7. Optimering av flyghastighet för flygplan

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

    Författare :Louise Larsson; [2023]
    Nyckelord :Aircraft flight speed; flight operations; speed optimization; Cost Index; ECON speed; Flyghastighet; flygverksamhet; hastighetsoptimering; kostindex; ekonomisk hastighet;

    Sammanfattning : Optimization of flight operations is a way to reduce the impact of aviation on the environment and make the use of airspace more effective. Reductions in fuel consumption and flight time are further desired by airlines to minimize operational costs. LÄS MER

  4. 8. Risk Analysis and Cybersecurity Implementation for UTM : Implemented in UTM50

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Inge Hannson; Fredrik Nääs; [2023]
    Nyckelord :UTM; U-space; UTM50; Drone; Drones; Cybersecurity; ZeroMQ; CurveZMQ;

    Sammanfattning : With the increasing usage of Unmanned Aerial Vehicle (UAV)s and the prediction of becoming applicable to more industries within the next decade there is a need for a controlling authority in the lower airspace. An Unmanned Aircraft System Traffic Man- agement (UTM) provides multiple solutions to how such a system should operate and what services it should provide. LÄS MER

  5. 9. Small scale VTOL aircraft using only one lift-producing motor : A study of lift capacity for a Vertical Take-Off and Landing capable aircraft

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Daniel Milenkovic; [2023]
    Nyckelord :Aircraft; VTOL; EDF; Mechatronics; Ardupilot; Luftfarkost; VTOL; EDF; Mekatronik; Ardupilot;

    Sammanfattning : The usage of unmanned aerial vehicles in applications such as terrain mapping and surveillance is proliferating in the modern world. This project aims to investigate the feasibility, in terms of payload capacity and stability, of small scale winged aircraft that have the ability to lift and land vertically, while also being able to transition to normal forward flight using wings for primary lift.

  7. 10. Machine Learning for State Estimation in Fighter Aircraft

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Axel Boivie; [2023]
    Nyckelord :State estimation; machine learning; fighter aircraft; neural networks; long short- term memory; LSTM; sensor fusion; air data system; ADS.; Tillståndsestimering; maskininlärning; stridsflygplan; neurala nätverk; sensorfusion; luftdatasystem.;

    Sammanfattning : This thesis presents an estimator to assist or replace a fighter aircraft’s air datasystem (ADS). The estimator is based on machine learning and LSTM neuralnetworks and uses the statistical correlation between states to estimate the angleof attack, angle of sideslip and Mach number using only the internal sensorsof the aircraft.
