中國航天公司航天運輸公司成功測試了其爆轟沖壓發動機，在65600英尺以上的高度實現了4馬赫（3106英里/小時）的速度。該發動機是為金斗400飛機開發的，旨在使北京和紐約之間的航班在短短兩個小時內完成。

清華大學設計的創新型沖壓轉子爆震發動機（RRDE）結合了旋轉爆震發動機和沖壓噴氣發動機技術，通過沖擊波產生推力，提高了效率并減小了發動機尺寸。這一突破消除了對壓縮機和渦輪機零件的需求。

太空運輸公司的成功測試標志著其開發云星超音速民用飛機的努力邁出了重要一步，10月份的原型飛行驗證了控制系統和耐熱性等關鍵技術，使該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.
