From Mach 0 to 6: this engine may power China’s future fighter jets and missiles
A single engine prototype, 30 years in development, could power next-gen fighters and missiles from standstill to hypersonic speeds.
Chinese researchers have completed and experimentally verified a prototype for a revolutionary 'contra-rotary ramjet engine,' a project over three decades in the making. The engine is designed to operate seamlessly from a stationary start-up to speeds exceeding Mach 6, a capability that could allow it to replace the combined turbine-ramjet systems currently used in high-speed aircraft and missiles. This development represents a significant step toward engineering applications for next-generation fighter jets and hypersonic weapons.
Conventional hypersonic propulsion requires separate systems: a turbine engine for sub-Mach 3 speeds and a ramjet or scramjet for higher velocities. The new Chinese engine prototype aims to unify this process into a single, continuous system. According to researchers, the next phase involves adapting the engine to various aircraft platforms and conducting real-world flight tests. Academician Xu Jianzhong framed the development as a strategic choice to break the Western monopoly on advanced propulsion technology and potentially achieve superiority.
- Prototype engine operates from standstill to over Mach 6 in a single system, eliminating the need for separate turbine and ramjet engines.
- The project represents over 30 years of development and has now reached the experimental verification stage.
- Next steps are platform adaptation and flight tests, aimed at powering future Chinese fighter jets and hypersonic missiles.
