    Abstract : Accurately modeling aerodynamic forces and moments are crucial for understanding thebehavior of an aircraft when performing various maneuvers at different flight conditions.However, this task is challenging due to complex nonlinear dependencies on manydifferent parameters. READ MORE

  3. 2. Splitting a Platoon Using Model Predictive Control

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

    Author : Albin Gustafsson; Emil Vardar; [2021]
    Keywords : Model Predictive Control MPC ; Platooning; Splitting; Linearized air drag; Constraints.;

    Abstract : When multiple autonomous vehicles drive closelytogether behind each other, it is called a platoon. Platooningprovides several benefits, such as decreased congestion andreduced fuel consumption. In order for more vehicles to takeadvantage of these benefits, the platoon should be able to openup a space for other vehicles to merge into. READ MORE

  4. 3. High Altitude Glider Solution for Returning From Space

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

    Keywords : Aerodynamics; aeronautics; gliding flight; nearearth space research; sounding rocket; KTH; REXUS; XFLR5; Simscale; CFD;

    Abstract : Space exploration drives the human expansion inthe universe. Succeeding in this challenge demands familiarityof the near earth space environment, achieved through soundingrocket experiments that often are lost upon return from space. READ MORE

  5. 4. Undertray Design and Development Procedure with CFD : An Optimization Study of Different UndertrayDesigns with CFD Computations

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Aaron Poutiainen; [2021]
    Keywords : ;

    Abstract : Race car aerodynamics has played a vital part to improve lap times over the years of motor racing. Having good road adhesion with slick tires and aerodynamic downforce will increase the vehicles maximum lateral force and thus higher cornering speeds can be achieved. READ MORE

  6. 5. Design and Qualification of a Gimbal Suspension for Attitude Control System Testing of CubeSats

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