1. 1. Implementation of Flight Mechanical Evaluation Criteria in an Aircraft Conceptual Design Tool with focus on Longitudinal Motions

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Argyro Giota; Aleksandra Roszkowska; [2023]
   Nyckelord :flight mechanics; Pacelab APD 8.1; aerodynamic derivatives; equations of motion; B747; stability and control; longitudinal dynamics; phugoid mode; short period mode; DATCOM ; OpenVSP;

   Sammanfattning : This report focuses on the utilisation of flight mechanics in the context of aircraftconceptual design to assess stability, control, and motion characteristics. The pri-mary objective is to acquire the equations of motion and implement longitudinalstability and control criteria using Pacelab Aircraft Preliminary Design 8. LÄS MER

3. 2. Airspeed estimation of aircraft using two different models and nonlinear observers

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Alexander Roser; Anton Thunberg; [2023]
   Nyckelord :sensor fusion; flight mechanics; Kalman filter; extended Kalman filter; unscented Kalman filter; pitot tube; airspeed estimation; simulation;

   Sammanfattning : When operating an aircraft, inaccurate measurements can have devastating consequences. For example, when measuring airspeed using a pitot tube, icing effects and other faults can result in erroneous measurements. LÄS MER

4. 3. Utan flygtekniker lyfter vi inte! : Vad lyfter professionen?

   Kandidat-uppsats, Högskolan i Halmstad; Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Författare :Mattias Anger; Maria Lugn; [2023]
   Nyckelord :Swedish Air Force; aviation technician; flight engineer; skills supply; professionalism; Flygvapnet; flygtekniker; färdmekaniker; kompetensförsörjning; profession;

   Sammanfattning : För att få flygvapnets flygoperativa resurser i luften krävs underhåll och klargöring av flygmaskinerna – för detta behövs flygunderhållspersonal. I denna forskning har vi utforskat hur kompetensförsörjning av flygtekniker och färdmekaniker kan utvecklas samt vad som påverkar synen på professionen. LÄS MER

5. 4. Exterior ballistics analysis for rocket propelled KE-penetrator - A conceptual simulation study within fluid mechanics and flight mechanics

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

   Författare :Emil Wegberg; [2022]
   Nyckelord :Exterior ballistics; fluid mechanics; high-speed aerodynamics; CFD; RANS; conceptual design; Ytterballistik; strömningsmekanik; höghastighetsaerodynamik; CFD; RANS; konceptuell design;

   Sammanfattning : This study has investigated the conceptual feasibility of a rocket propelled kinetic energy penetrator (KEP), designed for the handheld recoilless rifle Carl-Gustaf® 84 mm calibre system, from an exterior ballistics perspective. The methodology is based upon evaluating the aerodynamic properties of different conceptual design proposals through CFD-simulations and then performing trajectory analysis to assess their exterior ballistic performance.

7. 5. Implementation of Machine Learning for Classification of Flight Simulation Data

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

   Författare :Karl Persson; William Josefsson Rudberg; [2022]
   Nyckelord :Machine learning; Classification; Flight mechanics; Flight simulations; FCAS; Gripen; Maskininlärning; Klassificering; Flygmekanik; Flygsimuleringar; FCAS; Gripen;

   Sammanfattning : The main objective of this thesis project is to explore the possibility of using machine learning as a way of categorizing flight simulation outcomes. If such a possibility exists, the process of analyzing whether a new configuration stays within given boundaries can be streamlined. LÄS MER
