The demonstrator will be used to help validate the engine's advanced technologies, China's Ministry of Industry and Information Technology (MIIT) says in a news release.
China plans to build 24 more CJ-1000A prototype engines to support an airworthiness certification campaign, with entry into service targeted after 2021.
The news release reveals two new dimensions of the indigenous Chinese rival to the CFM International Leap-1C to power the C919.
The CJ-1000AX has a diameter of 1.95m (76.8in) and a length of 3.29m (10.7ft), the release says. That compares to the 1.98m diameter and 3.32m length of the Leap-1C. The shorter length of the CJ-1000AX is likely explained by a design that compared to the Leap-1C uses one fewer stage of rotating blades in the low pressure turbine.
