1. 1. Temporary Halting of Wind Turbine Rotors toMitigate Effects on Birds

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Ola Hedberg; [2024]
   Keywords : Bird; mitigation; effect; wind farm; turbine; wind power; halting; collision; risk; birds; power; generation;

   Abstract : This study assesses the viability of temporarily halting wind turbine operations as amitigation measure to protect bird populations during migration periods. Conducted in thenorthern Baltic, it examines the migration patterns, timings, and altitudes of various birdspecies, aiming to identify the most critical times for implementing turbine stoppages.

3. 2. Dynamic Consequences of Bearing Radial Clearance in Jeffcott Rotors

   University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

   Author : Marcus Bohman; [2023]
   Keywords : ;

   Abstract : Earlier research on bearing radial clearance on a vertical Jeffcott rotor is rare, but an interesting and realistic point of view in a rotor system. Applying this force to the system produces interesting results for a vertical Jeffcott rotor. READ MORE

4. 3. Compressor Surge: Simulation, Modeling and Analysis

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Robin Massiquet; [2022]
   Keywords : Turbo compressor; Surge; Simulation; Modelling;

   Abstract : The master thesis subject takes place in the automotive industry and specifically in the internal combustion engine area. The need of improving the efficiency of the engines leads to develop new technologies like turbo compressors. Some of the challenges to overcome are high rotational speed difficulties or extreme load and fatigue in the rotors. READ MORE

5. 4. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Simon Pääjärvi; [2022]
   Keywords : Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

   Abstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE

6. 5. Design, Modelling and Control of a Space UAV for Mars Exploration

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Akash Patel; [2021]
   Keywords : ;

   Abstract : Mars : The red planet has been on top in the priority list of interplanetary exploration of the solar system. The Mars exploration landers and rovers have laid the foundation of our understanding of the planet atmosphere and terrain. READ MORE
