  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. A final drive device for torque vectoring in small racing cars

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Sven Kalkan; [2023]
    Keywords : Torque vectoring; differential; formula student; racecar; racing; BorgWarner; product development; Technology and Engineering;

    Abstract : The agility of the car can be improved by distributing the longitudinal tire forces unevenly between the wheels. The resulting yaw moment helps the car to steer in transient driving scenarios, like on a slalom course. The available grip in steady state cornering can also be increased along with stability.

  4. 3. Control of an Over-Actuated Vehicle for Autonomous Driving and Energy Optimization : Development of a cascade controller to solve the control allocation problem in real-time on an autonomous driving vehicle

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gianmarco Grandi; [2023]
    Keywords : LTV-MPC Linear Time-Varying Model Predictive Controller ; Trajectory following; Energy consumption; Vehicle stability; Vehicle model; Real-time performance; LTV-MPC Controllo a predizione del modello lineare tempo variabile ; Inseguimento di traiettoria; Consumo energetico; Stabilità del veicolo; Modello del veicolo; Prestazioni in tempo reale; LTV-MPC Linjär tidsvariabel modellförutsägande styrning ; spårföljning; energiförbrukning; fordonsstabilitet; fordonsmodell; prestanda i realtid;

    Abstract : An Over-Actuated (OA) vehicle is a system that presents more control variables than degrees of freedom. Therefore, more than one configuration of the control input can drive the system to a desired state in the state space, and this redundancy can be exploited to fulfill other tasks or solve further problems.

  5. 4. 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.

  6. 5. The Impact of Violence on Interpersonal and Institutional Trust : Evidence from Mexico

    University essay from Uppsala universitet/Nationalekonomiska institutionen

    Author : Mårten Randau; [2022]
    Keywords : trust; interpersonal trust; institutional trust; violence; battles; violence against civilians; riots;

    Abstract : Beyond the material consequences, violence can have a great psychological impact on the individual. Violence can cause institutional and interpersonal distrust, and in turn harm economic growth and political stability. As of today, there is more knowledge about the consequences of trust than its determinants, and longitudinal studies are scarce. READ MORE
