CTF-3 Turbofan Engine (650 kgf)

CTF-3 turbofan engine is independently developed by Beijing Power Machinery Institute, China. CTF-3 is a two-spools turbofan engine with a thrust level of 650 kgf. It was designed for small unmanned aerial vehicles (UAV) with high-altitude, long-endurance. The engine has outstanding characteristics of high performance and compact structure, and it has adopted advanced electrical, control system and safety-health management system. With its superior performance, CTF-3 can satisfy various power requirements of small unmanned aerial vehicles with high ceiling and large range. The engine performance has achieved the domestic leading level.
