1. Simulation of Combustion in a Hybrid Rocket Engine
University essay from KTH/Skolan för teknikvetenskap (SCI)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

2. Design of a modular small-scale PMMA/Air hybrid rocket research engine
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : 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.

3. Parametric study on hybrid rocket propulsion system performance measured by the system specific impulse
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : Hybrid rocket motors have become of great international interest during the last couple of years. A hybrid rocket motor is propelled by the use of a solid fuel and a liquid oxidizer. The fundamental principle of the hybrid propelled system is that the liquid oxidizer is injected into a combustion chamber to enable the combustion of the solid fuel. READ MORE

4. Formulation and Assessment of Hexamethylene-tetramine Filled Solid Fuel Grains
University essay from KTH/Fiber- och polymerteknologiAbstract : Hybridraketer har inte sett så mycket användning som dess motsvarigheter som använder flytande eller fasta drivmedel. De främsta orsakerna kan förklaras med att hybridraketer historiskt sett haft lägre regressionshastighet och bränsletäthet. Inverkan av nackdelarna har dock minskat tack vare fortsatt forskning rörande hybridraketer. READ MORE

5. Numerical study with computational fluid dynamics of hybrid rocket engine.
University essay from Luleå tekniska universitet/RymdteknikAbstract : In this thesis a Large Eddy Simulation (LES) of a hybrid rocket engine burning ethylene (C2H4) in nitrous oxide (N2O) is explored. This is done primarily using a solver and solution scheme provided by the Swedish Defence Research Agency (FOI) and an (at this date) unpublished chemistry model. READ MORE
