中国航天公司航天运输公司成功测试了其爆轰冲压发动机，在65600英尺以上的高度实现了4马赫（3106英里/小时）的速度。该发动机是为金斗400飞机开发的，旨在使北京和纽约之间的航班在短短两个小时内完成。
清华大学设计的创新型冲压转子爆震发动机（RRDE）结合了旋转爆震发动机和冲压喷气发动机技术，通过冲击波产生推力，提高了效率并减小了发动机尺寸。这一突破消除了对压缩机和涡轮机零件的需求。
太空运输公司的成功测试标志着其开发云星超音速民用飞机的努力迈出了重要一步，10月份的原型飞行验证了控制系统和耐热性等关键技术，使该公司更接近高超音速旅行能力。
A Chinese aerospace company, Space Transportation, has successfully tested its detonation ramjet engine, achieving speeds of Mach 4 (3,106 mph) at altitudes over 65,600 feet. The engine, developed for the JinDou400 aircraft, aims to enable flights between Beijing and New York in just two hours.
The innovative Ram-Rotor Detonation Engine (RRDE), designed by Tsinghua University, combines rotary detonation engine and ramjet technology to produce thrust through shock waves, improving efficiency and reducing engine size. This breakthrough eliminates the need for compressors and turbine parts.
Space Transportation's successful tests mark a significant step in its efforts to develop the Yunxing supersonic civilian plane, with a prototype flight in October validating key technologies like control systems and heat resistance, moving the company closer to hypersonic travel capabilities.
