Xinghe Power Aerospace completed a 130-second long-duration rated test of the
CQ-90 (Cangqiong-90), a new-generation 100-ton-class liquid oxygen/kerosene main
engine for the reusable Zhishenxing-2 launcher, at the Niutoushan test stand.
The run was stable and met design performance; the engine has recorded more than
20 developmental test firings and has entered a reliability-verification phase
toward engineering standardization and flight application, supplying core
propulsion for stage vertical recovery and reuse.
