  1. 1. Wake analysis for NACA4412 in free-flight condition

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : William Nord Nilsson; Oskar Hedström; [2021]
    Keywords : ;

    Abstract : The purpose of this project is to evaluate the differences in the wake of a NACA 4412 airfoil in free-flight condition compared to wind tunnel and also investigate wall-interference. This was done using two sets of angles of attack, 5 degrees and 8 degrees. READ MORE

  3. 2. Numerical Study on Aerodynamic Drag Reduction on a Rear Wing of a Formula Student Car

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mahim Ahsan; [2021]
    Keywords : ;

    Abstract : The importance of aerodynamics in racing has increased substantially over the past decades. Racing vehicles utilize different aerodynamic devices, to redirect the airflow around the vehicle in a beneficial way. The increase in downforce using an aerodynamic wing package increases drag force. READ MORE

  4. 3. Vertical landing flight envelope definition

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Jack Charles Hooper; [2020]
    Keywords : trajectory optimization; pseudospectral; optimal control; re-entry; high speed aerodynamics; high angle of attack;

    Abstract : This paper will investigate the development of a landing footprint for a re-entry vehicle. Vehicles can re-enter the atmosphere with a range of orientations, velocities and flight path angles. READ MORE

  5. 4. Design of a drone system for maritime search and rescue missions

    University essay from KTH/Flygdynamik

    Author : Emil Pettersson; [2020]
    Keywords : Sea Rescue; Drone; Flying Wing; Blended Wing Body; SAR; Tailless; BWB; XFLR5; Search and Rescue; Drönare; Flygande Vinge; Sjöräddning; Eftersök; XFLR5;

    Abstract : The work summarized in this report aims to investigate how a drone airplane design can be optimized to create a safer and more efficient sea rescue by providing staff with an early picture, performing search missions and aiding communication through visual contact. A flying wing is in theory one of the most efficient designs for a fixed wing aircraft, at the same time as it also offers high structural efficiency for its given size. READ MORE

  6. 5. Enabling high-fidelity measurements of turbulent boundary layer flow over wing sections in the MTL wind tunnel.

    University essay from KTH/Mekanik

    Author : Fermin Mallor; [2019]
    Keywords : Fluid mechanics; aerodynamics; turbulence; RANS; wind-tunnel experiments; insert design; Strömningsmekanik; aerodynamik; turbulens; RANS; vindtunnel experiment; inlaga designen;

    Abstract : A reinforced fiber-glass model of a NACA 4412 wing profile is designed and set-up in the Minimum Turbulence Level (MTL) wind tunnel facility at KTH. The model has 65 pressure taps orifices, and the set-up includes two mounting panels designed to allow for particle image velocimetry (PIV) and hot wire anemometry (HWA) measurements of the boundary layer (to be performed in a future campaign).
