Speech Title:
Innovation and Prospects in Ramjet and Combined Cycle Engines
 
Abstract:
Ramjet engines and combined cycle propulsion are pivotal technologies for advancing aerospace science and enabling spaceflight, serving as key development hotspots and strategic frontiers for global powers. These systems can operate across aviation, near-space, and even outer space in terms of altitude, while achieving speeds ranging from zero to hypersonic or even the first cosmic velocity. As integrated propulsion devices combining aviation (aerodynamic) and aerospace (rocket) characteristics, they are primarily applied in three major domains: "hypersonic/ultrahypersonic missiles, near-space high-speed aircraft, and aerospace vehicles." This report outlines domestic and international research progress in ramjet and combined cycle propulsion, innovative practices addressing the critical demands of high-altitude, high-speed, highly maneuverable, and wide-speed-range operation for hypersonic/ultrahypersonic vehicles, and presents future development prospects.
