可能這是一個新的超燃沖壓發動機
The January test of the Wu-14 hypersonic vehicle signaled the beginning of what analysts say is the start of a new high-technology arms race to build high speed maneuvering strike vehicles.
The United States is developing both scramjet-powered and glide-hypersonic missiles. Russia’s government has made development of hypersonic missiles a priority.
The Chinese report outlines in technical detail how a scramjet-powered cruise vehicle operates at speeds greater than Mach 5 and discusses how to integrate airframe design with scramjet propulsion.
A scramjet is an engine that uses supersonic airflow to compress and combust fuel, creating a highly efficient propulsion system with few parts.
The report analyzed “preliminary design methods for airframe/engine integrative configuration.”
The analysis “may serve as a basis for quick preliminary design and performance evaluation of airframe/engine integrative configuration” for a future Chinese hypersonic cruise vehicle, the report said.
The scramjet cruise vehicle was described in a technical military journal called Command Control & Simulation. The article was published by the 716 Research Institute of the state-run China Shipbuilding Industry Corp., China’s largest maker of warships, submarines, and torpedoes.

The study by China’s major naval weapons builder is a sign the PLA may be considering the strike vehicle for use against U.S. aircraft carriers and warships as part of what the Pentagon calls “anti-access, area denial” weapons.
China’s hypersonic weapons are among the most secret programs within the Chinese military, along with anti-satellite weapons and cyber warfare tools. However, China’s Defense Ministry confirmed the test asserting that it was “normal” scientific experiment and not aimed at any foreign state.
Military experts said the disclosure of the scramjet cruise missile is unusual and part of China’s large-scale high-technology arms buildup.
“China long ago identified hypersonics as a critical future military technology and has invested heavily in its development for future weapons,” said Rick Fisher, with the International Assessment and Strategy Center. “The old Bush administration concept of Prompt Global Strike using hypersonic non-nuclear warheads may be dormant in Washington, but it is very much alive and flourishing in Beijing.”
Fisher said a scramjet vehicle would have advantages over the Wu-14 glide vehicle, including better-sustained speeds, some maneuvering, and a depressed trajectory that would complicate efforts by U.S. missile defenses to intercept the ultra-fast maneuvering strike missile.
China’s Chengdu Aircraft Corporation has been leading the development of a hypersonic scramjet engine test platform similar to the decade-old Pentagon-NASA X-43, Fisher said.
