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

    University essay from KTH/Kraft- och värmeteknologi

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

    Abstract : 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.

  4. 3. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Hanna Grahn; Matilda Eriksson; [2023]
    Keywords : Large-scale heat pump; refrigerant; COP;

    Abstract : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

    Abstract : With the Paris agreement calling to limit global warming to 2°C below pre-industrial levels, with further efforts to ensure it stays below 1.5°C, the Finnish government passed the Lakihiilen energiakäytön kieltämisestä (416/2019), i.e. READ MORE

  6. 5. Digitalisation online condition monitoring and AI analysis in a vacuum pump

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Kim Daniel Muzito; [2018]
    Keywords : ;

    Abstract : Billerudkorsnäs is a good example of an industry that associated with a 24/7 production and where faults lead to downtime in the production process which in its turn generates substantial losses. Sustainability is essential for a prosperous future for Billerudkorsnäs, and with the growth of technologies and digitalization with big data that are in line with the coming Industry 4. READ MORE
