1. Development of a Low Noise Drone Propeller Using CFD Simulations
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : Noise pollution generated by drones has in recent years become a concern for humans and wildlife and has in some regions resulted in regulatory backlash. This thesis investigates the possibilities of developing a low noise drone propeller using computational fluid dynamics (CFD) simulations. READ MORE

2. Load Control Aerodynamics in Offshore Wind Turbines
University essay from KTH/Kraft- och värmeteknologiAbstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE

3. Conceptual design and construction of a UAV wing structure
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : This report presents the design of the wing structure for a UAV called Skywalker X8. A model of the UAV was given and analyzed to design a wing box structure that is twice the size of the current model, with "greener" technology and lightweight materials. READ MORE

4. Material Transfer Mechanisms during Interaction of Aluminium Alloy and Tool Steel at Elevated Temperatures
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Hot stamping of aluminium alloys allows for increased formability, decreased springback and the possibility of integrating age-hardening heat treatments into the process. However, it can be challenging due to the occurrence of material transfer of aluminium onto the tool, as aluminium is prone to adhesion even at low temperatures. READ MORE

5. Enabling high-fidelity measurements of turbulent boundary layer flow over wing sections in the MTL wind tunnel.
University essay from KTH/MekanikAbstract : 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).
