  1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Nipon Roy; [2023]
    Nyckelord :Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Sammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER

  3. 2. Empirical Verification of an Acoustic Estimation of a Rocket Engine : A Comparison Between Estimated and Measured Noise of a Rocket Engine

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Elina Arvidsson; [2022]
    Nyckelord :Esrange Space Centre; Flame deflector; Acoustic estimation; Liquid rocket engine; Rocket Factory Augsburg; Jet acoustics; Esrange Space Centre; Flammdeflektor; Akustisk estimering; vätskedriven raketmotor; Rocket Factory Augsburg; strömningsakustik;

    Sammanfattning : The noise of a rocket engine is a complex and complicated phenomenon which has been studied for more than half a century [1]. There are many sources to this noise, but due to its great potential impact to the surrounding structures, including the vehicle itself, it is important to have a model to estimate the acoustic environment the engine produces.

  4. 3. Design of an Incubator Platform for Biological ISS Experiments

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Anne Sophie Hartmann; [2021]
    Nyckelord :ICE Cubes; BioCube; SpaceMaster; ISS; Space System Engineering; Space Applications Service; Space Experiment; Rapid Prototyping;

    Sammanfattning : The first European commercial research facility aboard the ISS, Space Applications Services' ICF, provides a platform for standardized plug-and-play experiments called ICE Cubes. The ICE Cubes Service provides engineering and operational support for ICE Cubes missions. LÄS MER

  5. 4. MOSFET Packaging for Low Voltage DC/DC Converter : Comparing embedded PCB packaging to newly developed packaging

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Emil Dahl; [2020]
    Nyckelord :embedded components; embedded MOSFETs; MOSFET packaging; power module;

    Sammanfattning : This thesis studies the options of using PCB embedding bare die power MOSFET and new packaging of MOSFET to increase the power density in a PCB. This is to decrease the winding losses in an isolated DC/DC converter which, according to "Flex Power Modules", can be done by improving the interleaving between the layers of the transformer and/or decreasing the AC loop.

  7. 5. Impact of Surrounding Objects on Inductive Wireless Power Transfer

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Brenda Odhiambo; [2019]
    Nyckelord :Wireless power transfer; inductive coupling; Qi Specification; effect of metals; Technology and Engineering;

    Sammanfattning : Many new models of smartphones and small electronic devices are using their wireless charging feature as a key selling point. This is due to the convenience of cable-free charging as well as not requiring multiple power adapters for charging different devices. LÄS MER
