While developing a turbofan for the Comac C919, China's state propulsion company plans to scale up the core to create an engine for the Craic CR929 Sino-Russian widebody airliner. The company evidently aims to do this alone, since it is working on research hardware for the big engine despite the signing of a cooperation agreement with Russia last year.The C919's turbofan, the CJ-1000, took a big step forward in the past few weeks with a hot test of a demonstrator engine. The propulsion company, Aero Engine Corp. of China (AECC), now aims at certifying the CJ-1000 in 2027 and putting it into service in 2030, about eight years behind the original schedule, says an industry source with insight into the program.The engine for the CR929 is the C J-2000. Its schedule calls for demonstration of a core-comprising the high-pressure spool and combustor-to be completed by 2023. The CR929 is due to go into service no later than 2027 with a Western engine, probably a derivative of the General Electric GEnx or Rolls-Royce Trent 7000. Craic is a consortium of Comac and United Aircraft Corp.
