Jianyuan Technology said it completed joint gimballed hot-fire tests of
Yuanxingzhe-1 stage 1 and 2 engines with their servo mechanisms and has
delivered the units to final assembly. Test results showed engines operated
normally, servos executed the full gimbal sequence as commanded, and measured
parameters met design specifications. The trial validated engine–servo
coordination, matching and reliability under ignition conditions and confirmed
first-stage continuous variable-thrust accuracy, underpinning the vehicle’s
maiden flight, orbital insertion and recovery plans.
