  1. 11. Optimering av flyghastighet för flygplan

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

    Author : Louise Larsson; [2023]
    Keywords : Aircraft flight speed; flight operations; speed optimization; Cost Index; ECON speed; Flyghastighet; flygverksamhet; hastighetsoptimering; kostindex; ekonomisk hastighet;

    Abstract : Optimization of flight operations is a way to reduce the impact of aviation on the environment and make the use of airspace more effective. Reductions in fuel consumption and flight time are further desired by airlines to minimize operational costs. READ MORE

  3. 12. The Operational Strategy Optimization of Distributed Energy System Based on MATLAB : A case study in Northeast China

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yujun Han; [2023]
    Keywords : Distributed Energy System; CCHP; operational strategy; Distribuerat energisystem; CCHP; operativ strategi;

    Abstract : China is the largest energy consumer worldwide, with a fast-growing rate. But the energy and environmental problems brought by its unbalanced energy structure and low energy efficiency restrict the sustainable development of China. The Distributed Energy System (DES) is one of the internationally recognized solutions to the problems. READ MORE

  4. 13. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Fritjof Nilsson; Yanjun Peng; [2023]
    Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

    Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

  5. 14. Ventilation for reduced indoor spread of Covid 19 and similar diseases : A literature review focusing on hospital environments

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Cyrus Ourak Pour; [2023]
    Keywords : COVID-19; SARS-CoV-2; Ventilation system; Mixing ventilation MV ; Displacement ventilation DV ; Under floor air distribution UFAD ; Ultraviolet light UV ; HEPA filter; COVID-19; SARS-CoV-2; Ventilationssystem; Blandningsventilation; Deplacementventilation; Luftfördelning under golv; Ultraviolett ljus; HEPA-filter;

    Abstract : Today, a significant portion of individuals’ time is spent indoors, estimated at approximately 90% of their total time. This raises concerns about the transmission of Coronavirus Disease 2019 (COVID-19) instigating Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and similar viruses and highlights the critical role of ventilation systems in indoor environments, which this study aims to investigate.

  6. 15. Small scale VTOL aircraft using only one lift-producing motor : A study of lift capacity for a Vertical Take-Off and Landing capable aircraft

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

    Author : Daniel Milenkovic; [2023]
    Keywords : Aircraft; VTOL; EDF; Mechatronics; Ardupilot; Luftfarkost; VTOL; EDF; Mekatronik; Ardupilot;

    Abstract : The usage of unmanned aerial vehicles in applications such as terrain mapping and surveillance is proliferating in the modern world. This project aims to investigate the feasibility, in terms of payload capacity and stability, of small scale winged aircraft that have the ability to lift and land vertically, while also being able to transition to normal forward flight using wings for primary lift.
