Structural analysis of the MIT Micro Rocket Combustion Chamber
The micro rocket is one of several power microelectromechanical systems (MEMS) under development at MIT. The micro rocket is experiencing structural failures at operating parameters far below the designed performance level. The deterministic strength of brittle materials, such as silicon, is …

Numerische Simulation des Wärmeübergangs in einer kryogenen Raketenbrennkammer
… phenomena on the heat load of a hydrogen/oxygen rocket combustion chamber into the adjacent regenerative cooled wall. The heat transfer in turbulent flow is a result of turbulent vortices and the heat conductivity of the fluid. The turbulent effects were represented by the q-omega Low-Reynolds …

Early Plume Development and NOx Chemistry in LOx/H₂ and LOx/CH₄ Liquid Rocket Engines
Projected rocket launch demand in the next 10 years predicts an order-of-magnitude increase in CO₂-equivalent gasses. Despite this expected increase in launch frequency, the on-Earth environmental impacts of off-Earth missions is still understudied, partially due to the lack of combustion and …
