  1. 1. 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

  3. 2. Jet Engine Recycle Model : A Case Study to Design a General Model to be Used on Jet Engines

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

    Author : Felicia Dyberg; [2023]
    Keywords : Jet Engine Recycling; Recycling of Aircraft; End-of-life Engines; End-of-life Aircraft; Sustainable Recycling; Innovative Recycling; Engine Materials; Circular Economy; 3D-printing.; Jetmotoråtervinning; Återvinning av Flygplan; Uttjänta Motorer; Uttjänta Flygplan; Hållbar Återvinning; Innovativ Återvinning; Motormaterial; Cirkulär Ekonomi; 3D-Utskrift.;

    Abstract : The focus on sustainability development together with the growing market of end-of-life jet engines is a reason for performing research on how to improve the recycling of jet engines. The reuse and recycling of the jet engines contributes to decreasing the need for new extracted material and processing and manufacturing new parts. READ MORE

  4. 3. External powder feed

    University essay from Mittuniversitetet/Institutionen för ingenjörsvetenskap, matematik och ämnesdidaktik (2023-)

    Abstract : Printed circuit boards (PCBs) are essential components in various electronic devices, playing a vital role in their functionality. Over time, PCBs have evolved significantly, becoming smaller, more complex, and multi-layered to meet the demands of advancing technology and consumer preferences. READ MORE

  6. 5. Tether-free Driveline Control for Water Propulsion Devices

    University essay from Lunds universitet/Ergonomi och aerosolteknologi; Lunds universitet/Certec - Rehabiliteringsteknik och Design

    Author : Isak Marklund; Axel Müller; [2023]
    Keywords : Dead man’s switch; electric surfboard; jet surfboard; machine learning; user experience; usability testing; neural network; decision tree; bootstrap aggregating; time series; Technology and Engineering;

    Abstract : For many machines, safety requires the constant presence of an operator, with the risk of damage or danger if the operator is unintentionally absent. Dead man’s switches (DMS) are commonly used to halt operations if this absence is detected, often relying on physical elements like leashes or buttons. READ MORE
