ItalyThe article discusses a Chinese breakthrough in hypersonic jet engine technology, specifically a variable geometry ramjet capable of adjusting its internal configuration during flight. The system was tested under simulated high-speed conditions and reportedly operated continuously from Mach 1.8 to Mach 6, surpassing traditional ramjets' capabilities. The innovation lies in its ability to dynamically adjust airflow in real-time, improving combustion efficiency and reducing reliance on auxiliary systems. Developed through collaboration between the Northwestern Polytechnical University and the Beijing Power Machinery Institute, the design uses a double-seal system involving ceramic fiber and graphite to minimize gas leakage, achieving up to a 1.9% reduction in losses compared to previous tests. The advancement highlights China's growing expertise in advanced aerospace technologies and underscores the strategic importance of materials like graphite, which the country controls significantly and has restricted exports of high-purity variants to the U.S.
