Large Turbojet Engine â 400 kgf / 420 daN Class
A single-shaft turbojet engine independently developed for high-speed target drone and large UAV applications. Delivers 420 daN (â400 kgf / 882 lbf) take-off thrust at only 69 kg dry weight â a thrust-to-weight ratio of 6.09:1. Transonic envelope up to Mach 0.95 and 13,000 m service ceiling.
Complete ground-test performance and subsystem parameters from the manufacturer datasheet.
Why the XX400WP stands apart in the 400 kgf thrust class.
6.09:1 thrust-to-weight ratio â among the highest in its class. More thrust per kilogram means greater payload fraction and longer endurance for your platform.
Full acceleration and deceleration in 10 seconds. Critical for target drone manoeuvring and dynamic mission profiles where throttle response matters.
Operates up to 13,000 m at Mach 0.95. The performance band where high-speed target drones and large reconnaissance UAVs operate.
Single continuous operation of â¥2 hours, with â¥120 seconds at maximum thrust. Designed for realistic, extended target presentations.
Rated for â¤8 g rms steady-state and â¤15 g rms transient vibration across 0â1200 Hz. Built for the harsh reality of catapult launch and recovery.
Runs on RP-3 aviation kerosene (GB6537-2006), widely available at military and civilian airfields. 4050 synthetic oil lubrication with <150 mL/h consumption.
Platforms where 400 kgf-class turbojet power makes the difference.
Subsonic-to-transonic aerial targets for air-defence training, weapons evaluation and threat simulation. The 30-hour design life aligns with expendable/recoverable target drone operational profiles.
Heavy-payload and long-endurance unmanned aircraft requiring jet propulsion for speed, altitude and mission flexibility beyond what piston or electric power can deliver.
University laboratories, defence research establishments and propulsion integrators requiring a production-grade 400 kgf-class turbine for demonstrator programmes.
The XX400WP is classified as a dual-use item. All international shipments require an end-user certificate (EUC) and are subject to the export control regulations of the People's Republic of China. Sheng-Fang Technology assists buyers throughout the licence application process.
Every engine ships with a complete instrumented test-cell report, manufacturer's certificate of conformity, and full shipping documentation. Typical lead time is 45â60 working days, plus 30â45 days for export licence approval.
