3. 2. Gear Modifications for Optimal Load Distribution

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Raghunath Adimoolam Ganesan; [2023]
   Keywords : Lead correction; Profile correction; Even load distribution; Thermal distortion.; helixkorrigering; profilkorrigering; jämn belastningsfördelning; termisk distorsion.;

   Abstract : In the early days of gear manufacturing, engineers aimed to produce teeth as close to the theoretical shape as possible. As machinery advanced and demand for high-speed, high-torque, and quieter transmissions grew, optimizing gear teeth became increasingly important [1]. READ MORE

4. 3. Conceptual design of the next generation gas turbines : Modelling of a hybrid electric mixed turbofan for a trainer aircraft

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Sophia Fisher; Michael Åkerström; [2023]
   Keywords : Hybrid propulsion; mixed turbofan; parallel configuration; performance;

   Abstract : To mitigate climate change, all sectors must contribute their part. Electric propulsion system is a promising approach to reduce emissions from the aviation industry. A major challenge is however the low energy density in today’s battery technology. READ MORE

5. 4. Fuel Transition for Gas Turbines : In a Changing European Energy Landscape

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Lovisa Langerak; [2023]
   Keywords : energy technology; gas turbine; energy transition; Europe; green fuels; hydrogen; ammonia; biofuels; energiteknik; gasturbin; energiomställning; Europa; gröna bränslen; vätgas; ammoniak; biobränslen;

   Abstract : The transition to renewable energy sources is vital to mitigate global warming and achieve the climate targets set by the EU. The availability of natural gas in Europe is challenged due to the Russian invasion of Ukraine, leading to a shift towards fossil-free alternatives. READ MORE

6. 5. Microstructural design and optimization of Nickel-based superalloys for gas turbines

   University essay from KTH/Materialvetenskap
