  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.

  3. 2. Battery storage implementation in Sweden and sizing software development

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Santiago Moreano Rojas; [2023]
    Keywords : ;

    Abstract : Due to the rampant growth of the penetration of renewables into the electrical grids across the world, more challenges appear in the way to assure the optimal operation of the energy system. More particularly, in the case of Sweden, the nuclear power decommissioning tendency and the 100% renewable energy target by 2040, set two strong additional motivations for the rise of issues regarding variability, uncertainty, stability, balancing and quality in the grid.

  4. 3. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Tanmmay Rout; [2023]
    Keywords : Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

    Abstract : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

  5. 4. Electrification and implementation of an uninterruptable power supply system at a medical center in the Talara Province, Peru

    University essay from KTH/Kemiteknik

    Author : Johnny Hagelin; [2023]
    Keywords : Photovoltaic engineering; Minor Field Study; Energy Resilience; UPS system; Energy poverty; Solcellsteknik; fältstudie; energiresiliens; UPS-system; energifattigdom;

    Abstract : Marginalisering gällande tillgång till elektricitet utgör en betydande utmaning i avlägsna områden i Peru. Elnätets stabilitet är låg och detta utgör ett hot mot viktig infrastruktur såsom sjukhus och vårdcentraler. READ MORE

  6. 5. Tools and Challenges in Evaluating Control Surface Airworthiness for a Blended-Wing-Body UAV

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Anton Åkesson; [2023]
    Keywords : ;

    Abstract : For transport aeroplanes the Blended-Wing-Body (BWB) configuration shows promise in improving aerodynamic efficiency. The Green Raven project strives to demonstrate hydrogen fuel-cell-electric propulsion on a 4 m wingspan BWB. READ MORE
