1. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System
University essay from Luleå tekniska universitet/RymdteknikAbstract : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. READ MORE

2. Functionnal Modelling and Simulation of the Off-Design Operation of a Cryogenic Engine
University essay from KTH/Kraft- och värmeteknologiAbstract : The Exploration Company is a French and German start-up that develops and operates Nyx, anorbital vehicle that also has a lunar version. This thesis focuses on the modeling and simulationof the o-design operation of the cryogenic engine of Nyx. READ MORE

3. Life Cycle Assessment of Electric Road Systems - Climate impact in comparison with battery electric vehicles, biogas vehicles and fuel cell electric vehicles
University essay from Lunds universitet/Miljö- och energisystemAbstract : One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where vehicles are charged dynamically.

4. Evaluation of Models and Optimisation Methods for Energy Minimisation of Drill Riggs
University essay from Linköpings universitet/FordonssystemAbstract : There are many benefits from using electrical powertrains over diesel powertrains within the mining industries, where some of these benefits come from reducing the pollution within the mines and therefore improve the working environment as well as reduce the ventilation costs required from ventilating these pollution. It is also desired to optimise the use of the vehicle to increase the efficiency and reduce fuel consumption of the vehicle. READ MORE

5. Optimal Control and Thermal Managementof Heavy-Duty FCHEV Powertrains : Minimizing hydrogen consumption of an FCHEV using numerical optimal control and an integrated energy and thermal management system
University essay from Linköpings universitet/FordonssystemAbstract : The CO2 emissions from road vehicles must be reduced in order to avoid a 1.5 ◦C global warming. To reduce tailpipe emissions, a strong trend is to electrify powertrains to shift away from the use of fossil fuel. Among alternatives, the fuel cellhybrid electric vehicle (FCHEV) is seen as a promising configuration. READ MORE
