  1. 1. 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.

  5. 4. Nature-based Solutions for Flood Risk Reduction, Contamination Control and Climate Change Adaption

    University essay from KTH/Hållbarhet och miljöteknik

    Author : Hanna Nordin von Platen; Matilda Gustafsson; [2018]
    Keywords : Nature- based solutions; wetlands; flood risk mitigation; sediment connectivity;

    Abstract : Heavy precipitation events are expected to increase in the future, due to climate change. This predicted change will increase the risk of flooding, especially in urban areas.
