  1. 1. Conceptual design of the next generation gas turbines : Modelling of a hybrid electric mixed turbofan for a trainer aircraft

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

    Author : Sophia Fisher; Michael Åkerström; [2023]
    Keywords : Hybrid propulsion; mixed turbofan; parallel configuration; performance;

    Abstract : To mitigate climate change, all sectors must contribute their part. Electric propulsion system is a promising approach to reduce emissions from the aviation industry. A major challenge is however the low energy density in today’s battery technology. READ MORE

  3. 2. Simulation of Combustion in a Hybrid Rocket Engine

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Oscar Andersson; [2023]
    Keywords : Thesis; Hybrid Rocket Engine; CFD; computational fluid dynamics; combustion;

    Abstract : A numerical investigation on the combustion mechanics of a hybrid rocket engine is performed through unsteady Reynolds-averaged Navier-Stokes simulation. The hybrid rocket engine model is based on an experimental laboratory scale engine design operating on GOX and HDPE as a propellant. READ MORE

  4. 3. Performance Evaluation of Kubernetes Autoscaling strategies on GKE clusters

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Johanna Nilsen; [2023]
    Keywords : Cloud Computing; Containerisation; Kubernetes; Google Kubernetes Engine; Autoscaling; Horizontal Pod Autoscaling; Vertical Pod Autoscaling; Hybrid Pod Autoscaling; Molntjänster; Containerisering; Kubernetes; Google Kubernetes Engine; Autoskalning; Horisontell Pod-autoskalning; Vertikal Pod-autoskalning; Hybrid Pod-autoskalning;

    Abstract : Cloud computing and containerisation have experienced significant growth in recent years. With cloud providers requiring users to specify resource limits and requests, the need for performance and resource optimisation has emerged in the cloud computing domain. READ MORE

  5. 4. Design of a modular small-scale PMMA/Air hybrid rocket research engine

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Gustaf von Platen; [2023]
    Keywords : hybrid rocket engine; PMMA combustion; rocket engine design; combustion diagnostics; rocket engine; regression rate; preliminary design definition; hybrid rocket engine simulation; gaseous oxidizer; transparent rocket engine;

    Abstract : Rocket propulsion using the hybrid-propellant scheme is a technology that offers much promise in applications where high-performance liquid rocket engines are deemed too complex and solid rocket motors are considered to lack performance or safety. However, despite extensive research, there is still a lack of knowledge in the theoretical aspects of hybrid rocketry, especially in the area of fuel-oxidizer mixing and fuel regression rate.

  6. 5. Electrically Assisted Turbocharger: Modelling And Control Strategy

    University essay from Linköpings universitet/Fordonssystem

    Author : Erik Vandor; Gabriel Ehlin; [2022]
    Keywords : EAT; VGT; VNT; Hybrid powertrain; electric turbocharger;

    Abstract : A major cause of CO2 emissions today is fossil fuel vehicles, and lowering these emissions is of key importance, resulting in increasing electrification and hybridisation nowadays. Turbochargers have been used for a long time to recycle exhaust gas heat losses to improve engine performance by compressing the intake air. READ MORE
