  1. 1. An overview of the development and potential of ceramic materials for use in micro gas turbines

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

    Författare :Alexander Ahlqvist Fehr; [2023]
    Nyckelord :Gas Turbines; Ceramics; Micro Gas Turbines; Gas Turbiner; Keramik; Mikro Gas Turbines;

    Sammanfattning : This paper presents an analysis of the potential of Micro Gas Turbines (MGT) with regards to performance, economic and durability considerations. The performance potential was assessed by calculating the cycle efficiency based on the Brayton cycle and the mechanical efficiency of the expansion turbine. LÄS MER

  3. 2. An integrated brake disc and electric drive for vehicle propulsion : A FEASIBILITY STUDY

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Johan Linder; [2016]
    Nyckelord :Axial flux; brake disc; core less rotor; in wheel motor; hub motor; quarter car model; segmented rotor; switch reluctance machine; single teeth winding.; Axialflödes; bromsskiva; enkeltandad lindning; hjulmotor; hub motor kvartfordonsmodell; rygglös rotor; segment rotor; variabel reluktansmaskin;

    Sammanfattning : In this thesis, the feasibility to integrate an brake disc and electric machine is investigated. In wheel motors (IWMs) have several advantages, such as saving space in the vehicle, individual and direct control at the wheels and the absence of a mechanical transmission. LÄS MER

  4. 3. Fiber optics communication failure modes

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Jonathan Rosenqvist; [2014]
    Nyckelord :Fiber optic cables; ESS; mechanical and thermal stress; fiber; singlemode; SM; multimode; MM; crushing; twisting; force; attenuation; dB; standard; nuclear power plant; nuclear radiation; fiber optiska kablar; mekaniska och termiska påfrestningar; krossande; vridande; kraft; dämpning; standarder; kärnkraftverk; nukleär strålning.; Technology and Engineering;

    Sammanfattning : This report examines fiber optic cables and their ability to transmit data when exposed to fire conditions. By performing various experiments the study aims to widen the knowledge base in an area that at the moment is scarce in information. LÄS MER
