| 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. |

| 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. |

| AI-Enabled Research on Rotating Detonation Combustion |
| Abstract: |
| This talk presents a review and discussion of the application of artificial intelligence (AI) to research on Rotating Detonation Combustors (RDCs). Rotating detonation combustion offers several advantages, including quasi-constant-volume combustion, high specific impulse, and wide operational adaptability, making it a promising technology for next-generation aerospace propulsion systems. However, the strongly unsteady and multi-scale coupled flow structures within RDCs, together with extreme high-temperature and high-pressure environments and complex reactive flow processes, pose significant challenges to conventional approaches in modeling, measurement, and numerical simulation. To address these challenges, this paper highlights representative applications of AI in RDC research through several case studies. In the modeling of RDC, models like CAE-LSTM, DeepONet, and self-attention-based temporal prediction networks are employed for real-time combustion mode identification and multi-step forecasting, providing new data-driven approaches for investigating mode bifurcation, wave competition, and instability transition mechanisms. In the measurement of RDC, DDPM and GAN are utilized to reconstruct spatiotemporal flow fields within the combustor from sparse sensor measurements and limited optical observations, enabling super-resolution flow field reconstruction. In the numerical simulation of RDC, a GPU-accelerated differentiable reactive flow solver is developed and integrated with an adjoint optimization framework to improve the efficiency of inverse parameter identification and optimization. n addition, a wide-operating-condition detonation characteristic database is established by integrating experimental and simulation data. Finally, considering recent advances in computational power and large-scale AI models, future prospects are discussed, including foundation models for fluid dynamics and combustion, intelligent CFD simulation platforms, and data-driven design methodologies. The rapid development of AI provides new technical pathways and opportunities for overcoming limitations in rotating detonation research. |

| Research Progress and Reflections on Ultra-Wide-Range Aerospace Combined Propulsion |
| Abstract: |
| Hypersonic aerospace flight platforms represent a strategic high ground for technological competition among major powers, and ultra-wide-range aerospace combined propulsion is the core power solution supporting reusable horizontal take-off and landing vehicles covering full flight speed domains. The US, Europe and Japan have advanced technical routes including RBCC, TBCC and pre-cooled SABRE, while domestic research institutions led by Northwestern Polytechnical University have achieved a series of key technological breakthroughs. Focusing on five major research orientations: high performance, adaptive flow channels, lightweight structures, intelligent control and low cost, this presentation systematically introduces advances in core technologies such as thermodynamic cycle optimization, high-efficiency flame stabilization, deformable flow passages, active thermal cooling and intelligent combustion regulation, and presents flight verification results of Feitian-1. It analyzes current bottlenecks restricting the development of combined propulsion, and puts forward development ideas centered on the PEALS technical system and building an industry-university-research collaborative innovation ecosystem under the new nationwide system, providing references for the engineering research of domestic aerospace combined propulsion and the construction of a powerful aerospace nation. |
