  1. 1. Evaluating the Performance of Propulsion System Elements in an Aerospace Company

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :David Fredouelle; [2023]
    Nyckelord :Turbomachinery; injector; test campaign; cryogenic; rocket engine; test bench; cold flow; Turbomaskin; injektor; testkampanj; kryogen; raketmotor; testbänk; kallt flöde;

    Sammanfattning : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions. LÄS MER

  3. 2. 3D Geological Modelling of the Subsurface Adjacent to Cementa’s Quarry in Skövde, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Minna Larsson; [2022]
    Nyckelord :3D model; limestone; cement production; resistivity; photogrammetry; Skövde; 3D modell; kalksten; cementproduktion; resistivitet; fotogrammetri; Skövde;

    Sammanfattning : Limestone is one of the main components of cement production. Limestone has been quarried in Skövde, Sweden, since the end of 19th century and Cementa AB has been operating the quarry since 1973. Aside from limestone, there are also Alum shale of Cambrian age, mudstones as well as bentonite layers of Ordovician age present in the quarry. LÄS MER

  4. 3. Jämförelse mellan Skogliga grunddata 2.0 och fältmätta beståndsvariabler i bestånd med huggningsklass S1 och S2

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Mats Remsö; [2020]
    Nyckelord :flygburen laserskanning; skattning av skogsegenskaper; fjärranalys; Svenska Riksskogstaxeringen;

    Sammanfattning : Den skattning av skogliga variabler som 2009 – 2015 för första gången genomfördes på nationell nivå, blev ett användbart och viktigt verktyg för skogsbruket. För att uppdatera de uppgifter som utvanns i första omgången, genomför nu Skogsstyrelsen tillsammans med Lantmäteriet och Sveriges lantbruksuniversitet, en andra skanningsomgång med start 2018.

  5. 4. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Mara Santaniello; [2020]
    Nyckelord :;

    Sammanfattning : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. LÄS MER

  7. 5. Direct multispectral photogrammetry for UAV-based snow depth measurements

    Master-uppsats, KTH/Geoinformatik

    Författare :Kathrin Maier; [2019]
    Nyckelord :Unmanned Aerial Vehicles UAV ; snow depth; direct photogrammetry; multispectral imagery; cryosphere;

    Sammanfattning : Due to the changing climate and inherent atypically occurring meteorological events in the Arctic regions, more accurate snow quality predictions are needed in order to support the Sámi reindeer herding communities in northern Sweden that struggle to adapt to the rapidly changing Arctic climate. Spatial snow depth distribution is a crucial parameter not only to assess snow quality but also for multiple environmental research and social land use purposes. LÄS MER
