T1  - The impact of guide tubes on flow separation in rocket nozzles
T2  - Aerospace Europe Conference 2023 - 10th EUCASS - 9th CEAS
N2  - Rocket engine test facilities and launch pads are typically equipped with a guide tube. Its purpose is to ensure the controlled and safe routing of the hot exhaust gases. In addition, the guide tube induces a suction that effects the nozzle flow, namely the flow separation during transient start-up and shut-down of the engine. A cold flow subscale nozzle in combination with a set of guide tubes was studied experimentally
to determine the main influencing parameters.

T1  - Design study of a 30kN LOX/LCH4 aerospike rocket engine for lunar lander application
T2  - Aerospace Europe Conference 2023 - 10th EUCASS - 9th CEAS
N2  - Based on lunar lander concept EL3, various LOX/CH4 aerospike engines were studied. A distinction was made between single and cluster configurations as well as ideal and non-ideal contour concepts. It could be shown that non-ideal aerospike engines promise a significant payload gain.
