The maximum flight Mach number is extended compared to other turbine-based cycles by removing the turbine from the hot airflow path. This combination of properties makes them particularly well suited for high-speed supersonic aircraft or the air-breathing ascent stage of spaceplanes. This work re-examines architectures previously studied in on-design steady conditions by including the off-design behaviour in fully transient simulations. The implementation of the required control mechanisms to stabilise and regulate the engine is included, which allows for assessing the feasibility of a more practical engine implementation and for examining the operability margins along the acceleration phase of a high-speed cruiser aircraft.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/05\/HiSST-2024-131.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Karel VAN DEN BORRE, F.
