Not sure for sure this is true but claim is here that WS9YZ (no AB version) has thrust of 5.6t with MTBO of 3000 hours and total service life of 8000 hours.

Those numbers weren't a claim; those were straight up part of the video advertisement for Jiutian back at Zhuhai last year (picture three of that post)

cute engine for the low altitude economy. Looks to be a piston engine. its rated speed reaches 6500 rpm, and its output power can exceed 53 kW. It is also simultaneously developing naturally aspirated and turbocharged rotary engine products, which will be gradually expanded to power medium-to-high altitude drones, supporting independent or random airworthiness certification; the product displacement covers 0.5L-1.5L, with power ranging from 50kW to 150kW, and can be applied to diverse fields such as urban air mobility, medium-to-long-distance logistics distribution, and aerial tourism.
