Ireland-based University of Limerick Aeronautical Society High-Powered Rocketry Team (ULAS HiPR) has announced the design and development of what it describes as the country’s first additively manufactured liquid rocket engine. Named Lúin of Celtchar, the engine is the product of a collaboration between the ULAS HiPR student team, the University of Limerick, and Irish Manufacturing Research (IMR). Reportedly, the propulsion system delivers 2 kilonewtons of thrust, burning isopropyl alcohol (IPA) and nitrous oxide, and features a water-cooled architecture. Crucially, all concept and design work was carried out entirely by students. Founded in 2022, ULAS HiPR now counts over 100 students across aeronautical, mechanical, software, and design engineering. The team designs, builds, and launch
