  1. 21. Simulation of electric machine in test rig

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Marcus Hagström; Peter Jaris; [2023]
    Keywords : Simulation; electrification; test rigs;

    Abstract : Electrification is a trend that is on the rise within the aviation industry. Electrifying more systems in airplanes leads to increased efficiency and safety. GKN Aerospace intends to simulate electric machines as a preliminary step before conducting real-world experiments for the purpose of testing different machine designs. READ MORE

  3. 22. Application of Lamb waves using piezoelectric technique for structure health monitoring

    University essay from KTH/Hälsoinformatik och logistik

    Author : Simon Mauritz; [2023]
    Keywords : Structural health monitoring SHM ; damage detection; Lamb waves; piezoelectric PZT ; printed circuit board PCB ; circuit simulation; Strukturell hälsoövervakning SHM ; skadedetektering; Lambvågor; piezoelektrisk PZT ; printed circuit board PCB ; kretssimulering;

    Abstract : Structural health monitoring (SHM) is damage detection strategy for aerospace, civiland mechanical infrastructure. This project tries to show that Lamb waves, that are being generated and sensed with piezoelectric transducers, can be used for damage detection in a SHM system. READ MORE

  4. 23. Experimental study on the effect of rocket nozzle wall materials on the stability of methane

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

    Author : Thomas L. Holmboe; [2023]
    Keywords : Methane; pyrolysis; catalysis; nickel; coke deposition; chemical modelling; GRI3.0; rocket nozzle; regenerative cooling;

    Abstract : There has recently been an increased interest in methane as a rocket propellant due to its physical properties as well as the possibility of in-situ resource utilization in places like Mars. As part of ESA’s Future Launcher Preparatory Program, KTH in cooperation with GKN Aerospace has started the MERiT program, which seeks to study the characteristics of methane under conditions found in rocket nozzle cooling channels.

  5. 24. Using Reinforcement Learning to Correct Soft Errors of Deep Neural Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yuhang Li; [2023]
    Keywords : DNN; Soft errors; Redundancy; DRL; DQN; Transfer learning; Training time; DNN; Mjuka fel; Redundans; DRL; DQN; Överföringsinlärning; Utbildningstid;

    Abstract : Deep Neural Networks (DNNs) are becoming increasingly important in various aspects of human life, particularly in safety-critical areas such as autonomous driving and aerospace systems. However, soft errors including bit-flips can significantly impact the performance of these systems, leading to serious consequences. READ MORE

  6. 25. Mechanical and thermal buckling analysis of laminated composite plates

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Aswin Paremmal; Roopak Kuruthukulangara Varghese; [2023]
    Keywords : composite material; Mechanical Buckling; Buckling analysis;

    Abstract : Composite laminated structures have many application fields such as aerospace, civil, marine, bio medical, transportation, and mechanical engineering because of their convenience in handling, and very good mechanical properties. Buckling behavior of laminated composite plates subjected to plane loads is indeed an important consideration in the primary design of aircraft and launch vehicle components. READ MORE
