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

    University essay from Linköpings universitet/Fluida och mekatroniska system

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

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Fordonssystem

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

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

    Abstract : 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.

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

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

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

    Abstract : 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. READ MORE

  6. 5. Oil Autonomy of a Turbojet

    University essay from KTH/Flygdynamik

    Author : Florian Steiner; [2022]
    Keywords : Fluid Mechanics; Turbojet; Oil circuit; Fluid Mekanik; Turbojet; Oljekrets;

    Abstract : The oil circuit of a jet engine is required to lubricate and cool mechanical parts. The oil is pumped from the oil tank and flows through heat exchangers. Then it is injected on the bearings for lubrication and cooling, before being scavenged at the bottom of the sumps and finally flows back to the oil tank. READ MORE
