| 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. |

| Reuasble Liquid Rocket Engine Technology |
| |
| Abstract: |
| Reusable liquid rocket engines have evolved into a core technology pursued by spacefaring nations across the globe. This report conducts an in-depth analysis of the major technical challenges confronting reusable engines, covering structural reliability, service life evaluation, multi-time ignition, deep throttling, reentry process control, fault diagnosis, inspection and maintenance, and other aspects. In response to the application requirements and technical bottlenecks of reusability, it puts forward key technical research tasks to be carried out, and further discusses the future development pathways for reusable engines. |

| The Principle of Uniformity of Machining and Measurement |
| |
| Abstract: |
| The development of manufacturing has progressed through mechanization, automatization, digitalization, and intelligentization. Machining and measurement are two aspects of manufacturing that have remained separate despite the increasing adoption of in-situ/on-line measurement applications. This report will discuss the principles of uniformity between machining and measurement from the perspective of atomic-scale manufacturing. |
