This study documents the research, design, and analysis of a supersonic plug nozzle concept that could be integrated to the refrigerant-based cold-gas propulsion system to possibly improve its performance.As documented in this thesis, CFD analysis showed that the outlined nozzle design method resulted in a feasible nozzle concept that has the ability to out-perform a conventional nozzle of the same area ratio.

To predict structural massof a launch vehicle more accurate at a conceptual design phase, a structural mass model was developed.
The modelpredicts a launch vehicle’s structural mass, thickness, center of mass and mass moment of inertia. Unlike a liquid rocket-engine, it is not possible to actively throttle the overall combustion of a solid rocket-motor.
However, such systems are still in an early development phase and one of the key areas requiring further investigations is the operation of the magnetic nozzle, the device meant to...
In Liquid Rocket Engine (LRE) design, knowledge of how the propellant atomization quality varies with respect to some injector design variables would be useful in predicting LRE performance.
Preliminary design optimal techniques were adopted to reduce nozzle length while keeping the exit area constant in the design.
Optimization produced a smooth flow by generating a parallel and uniform flow at the exit. in Aeronautical Engineering from Seoul National University in 19, respectively. D from the University of Illinois in Urbana-Champaign in 1992. Lee is currently a Professor at the Department of Aerospace Engineering in Konkuk University in Seoul, Korea.Some of these investigations are focused on the heat flux to the chamber walls, changes in which can cause a significant shift in chamber wall...Accurate dry mass prediction is essential in early design phases of a launch system.Based on the information presented in this thesis, university-based satellite teams can manipulate the inputs of the design and analysis methods to investigate the use of an aerospike nozzle design concept to meet their design goals"--Abstract, page iii.The German Aerospace Centre (DLR) has in the past years been performing test runs with their experimental sub-scale combustion chambers to measure and investigate the effects of unstable combustion.The flow-fields and thrust of the aerospike nozzle, for the full and truncated nozzles, were investigated.The purpose of this study is to investigate other rocket nozzles that might have the ability to improve performance of a propulsion system without a large penalty on vehicle mass or cost.An igniter for a LOX/CH4 rocket engine is designed and a CFD model is developed which is used to model the designed igniter.Verification and validation methods are discussed.... To launch a rocket to the edge of space using a pressure fed rocket system with liquid oxygen as propellant, you need to know exactly how much pressurant gas (helium) you need to take along.Then the optimal trajectory for thrust limited rockets, the...Pulsed fusion propulsion might finally revolutionise manned space exploration by providing an affordable and relatively fast access to interplanetary destinations.
