At 9:00 am on December 17,MK sports 2024, the "JINDOU" (codenamed "JINDOU400") ramjet engine successfully completed its scheduled test flight. The engine achieved over 400 kilograms of thrust and reached Mach 4 speeds at altitudes exceeding 20 kilometers. Featuring detonation combustion technology and a modular design, the engine is compact, functionally independent, and easy to maintain, offering immense commercial potential for high-speed flight in near-space environments.

This test flight yielded in-flight performance data for the engine and included integrated assessments of critical technologies and systems, including the fuel supply, electrical, and control systems. The results fully validated the engine's stability and reliability, marking its transition from prototype to product. This milestone lays a solid foundation for the development of the "YUNXING" supersonic aircraft.
