United States, Sept. 22 -- GE Aerospace announced the successful demonstration of two distinct rotating detonation combustion (RDC) engines at its Aerospace Research Center in Niskayuna, New York: a missile-scale ramjet and a dual-mode ramjet for high-speed aircraft. This achievement - which could enable high-speed flight and extended range across numerous multi-mission platforms - represents the latest milestone in GE Aerospace's diverse portfolio of hypersonic propulsion programs.The test campaign exceeded expectations, demonstrating robust operation and a threefold (3X) increase in engine airflow compared to previously flight-tested (legacy) hypersonic technology demonstrators. RDC enables higher thrust, and improved efficiency at a smal...
