  1. 1. Tolerance design approach to meet Zero defect requirements on aerospace components

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Carl Melldén; [2022]
    Nyckelord :;

    Sammanfattning : In manufacturing, variation is and will always be present. To control and define variationtolerances are of paramount importance. LÄS MER

  3. 2. Application of mass defect filtering and statistical analysis for non-target data mining of gas and soot data from a study testing different firefighting methods

    Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Danielle Ydstål; [2020]
    Nyckelord :;

    Sammanfattning : Due to the high temperatures during a fire event, a large variety of compounds are formed or released from burning materials, all of which have a varying degree of environmental effects. In an incidental fire there are several variables that are important for which and how much combustion products that are formed, including the burning material, ventilation (presence of air), and temperature.

  4. 3. Development of method for processing brittle-hard materials using Laser Metal Deposition (LMD)

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Alejandro Simó Vesperinas; [2018]
    Nyckelord :Additive Manufacturing AM ; Laser Metal Deposition LMD ; Direct Metal Deposition DMD ; High-temperature materials; Mo-Si-B alloy; Residual stress; Cracks;

    Sammanfattning : New materials capable of operating at ultra-high temperatures in gas turbine engines are highly desired. Materials such as silicides of refractory metals present great potential to substitute single crystal nickel-based superalloys. LÄS MER

  5. 4. Master thesis within light warhead for support weapon : Investigation of defects, methods and requirement specifications in order to get a shell body shatter free

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Adam Jansson; [2016]
    Nyckelord :warhead; support weapon; shell body; shatter free; defect; method; carbon fibre; epoxy; crack; delamination; porosity; CFRP; CFRE; NDT; verkansdel; understödsvapen; granathylsa; splitterfri; defekt; metod; kolfiber; epoxi; spricka; delaminering; porositet; OFP;

    Sammanfattning : At launching the shell body, especially the backplane of the shell body, will be exposed to very high stresses due to acceleration, pressure and increased temperature from the propellant combustion. Defects in the shell body could in worst case for example result in high temperature gas leakage into the warhead and thereby ignite the explosives before exiting the launcher. LÄS MER

  7. 5. Cheeses with blowing defect : problematics and preventable methods

    Kandidat-uppsats, SLU/Dept. of Food Science

    Författare :Amanda Alvenäs; [2015]
    Nyckelord :blowing defect; gas defect; cheese spoilage; cheese problems; feljäsning; sprängd defekt; ostförstörelse; ostproblem;

    Sammanfattning : Blowing defect of cheeses refers to undesirable openness of the cheeses interior. It is a result of unwanted microbial metabolism. Production of hard- and semi-hard chesses require methods and/or preservatives to make sure that blowing defect is prevented. LÄS MER
