Zhuhai Shengfang Technology builds the XX400WP, our 400 kgf-class turbojet engine, and is an authorized distributor for SWIWIN turbine platforms — covering 6 to 400 kgf for high-speed unmanned aircraft and large industrial platforms.
XX400WP · 400 kgf
Large Turbojet Engine — 400 kgf Class
A single-shaft turbojet engine independently developed for high-speed UAV and large unmanned aircraft applications. Delivering 420 daN (≈400 kgf / 882 lbf) of take-off thrust at only 69 kg dry weight, the XX400WP achieves a thrust-to-weight ratio of 6.09:1 — a benchmark in its class.
Rated for 30 hours / 10 start-stop cycles with a 6-year storage life, it is engineered for operators who demand transonic performance, rapid response and mission reliability.
The 400 kgf thrust class sits in a niche where only a handful of manufacturers worldwide compete. We built the XX400WP to give high-speed UAV integrators a credible, production-ready option.
400 kgf thrust from a 69 kg package. The 6.09:1 thrust-to-weight ratio enables larger payload fractions and longer loiter time for your platform.
Certified for Mach 0.95 at up to 13,000 m — the performance band where high-speed UAV and long-endurance unmanned platforms operate.
Complete test reports, spec sheets and shipping documentation. Dual-use item export compliance handled end-to-end — you get a cleared shipment.
Sixteen SWIWIN turbine platforms from 5.5 to 80 kgf, plus our 400 kgf flagship. Every engine ships with a complete instrumented test-cell report and a published datasheet.
