Safran Ardiden 3C turboshaft variant, also designated WZ16 in the Chinese certification and production context. Safran specifies a 1,700–2,000-shp class twin-spool centrifugal-compressor design with next-generation FADEC, joint development with AECC, EASA and CAAC certification, and AC352 installation/test context. CAAC records 1,249 kW takeoff power, production approval in 2021, and four WZ16 deliveries for Z15 helicopters by the end of 2023; active production evidence is now established, while an exact Z15 relationship remains outside this row until a canonical vehicle-family ID is available.
