General
Multiple Chinese sources are reporting that (a.k.a. Space Transportation) has carried out a test flight of its supersonic transport technology demonstrator named Yunxing (云行). Yunxing is envisioned to be a Mach 4 passenger transport. Lingkong is also known to be working on hypersonic transports.

Yunxing supersonic transport is intended to be powered by Jindouyun (筋斗云) engines (first image), which will be flight tested in about a month.

The test flight of the Jindouyun ramjet engine took place earlier today and was a complete success.
2024年12月17日9时,"筋斗云"(代号"JINDOU400")高速冲压发动机试飞圆满成功。该型发动机推力超过400公斤,在20公里以上高空实现了4倍音速飞行。发动机采用了爆震燃烧技术,引入模块化设计,在临近空间高速飞行领域拥有巨大的商业应用潜力,为"云行"系列超音速飞机的研制打下了坚实基础
At 9:00 on December 17, 2024, the test flight of the "Jindouyun" (codenamed "JINDOU400") high-speed ramjet engine was a complete success. The thrust of this type of engine exceeds 400 kg, and it can fly at 4 times the speed of sound at an altitude of more than 20 kilometers. It has huge commercial application potential in the field of near-space high-speed flight, laying a solid foundation for the development of the "Yunxing" series of supersonic aircraft.
