1. Evaluating the Performance of Propulsion System Elements in an Aerospace Company
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : 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. LÄS MER
2. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : 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. LÄS MER
3. Simulation of Combustion in a Hybrid Rocket Engine
Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : 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. LÄS MER
4. Design of a modular small-scale PMMA/Air hybrid rocket research engine
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : 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. LÄS MER
5. Development and Analysis of a Gaseous Hydrogen-Oxygen Rotating Detonation Combustor
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : Theory suggests that more efficient rocket propulsion can possibly be achievedby utilizing a pressure-gain detonative combustion process instead of conventional deflagration combustion. To demonstrate this, rotating detonation engines that sustain one or several detonation waves in an annular enclosure havebeen a subject of research for decades. LÄS MER
