Project description
Third-cycle subject: Energy Technology
A propulsion system using hydrocarbons, liquid or hybrid, is a grand challenge for today’s rocket and space propulsion systems. As a consequence of the good performance in specific thrust (~380 s) in combination with operating benefits such as low toxicity, availability, storage stability and low production cost, high methane-content liquid biogas/natural gas (LNG) is one of the most interesting future solutions as propellant for rocket engines with liquid fuel. This in combination with the good cooling capabilities of methane makes it ideal for rocket engines and is therefore brought forward as an alternative fuel in European rocket engines. Quantitative information is missing in the open literature of the heat transfer characteristics for nickel alloy steels under the influence of hydrocarbon fuels at high temperatures and pressure. The project will experimentally and numerically study the heat transfer characteristics and material influence for typical cooled nozzles.
During the last years a research group has been built at the Department of Energy Technology in collaboration with the Swedish industry regarding heat transfer research in cooled rocket nozzles, and an advanced test rig has been established that will be used within the project. The research project is a part of the national space research program (NRFP4) with funding from the Swedish National Space Agency (SNSA) and the Swedish industry. Project reporting is towards the SNSA and collaborating company. The research project is an associated project within the KTH Space Centre.
