Chengdu-built F918 turbofan engine successfully ignited, designed for high-altitude drones
On December 26, Sichuan media reported that the F918 turbofan engine-developed under the leadership of Tianfu Light Power Technology Co., Ltd.-has successfully completed ignition testing in Chengdu. The engine delivers 2,000 kg (4,409 lb) of thrust and is designed for high-end unmanned aerial vehicles (UAVs) and mid‑to‑lightweight utility aircraft.
The F918 marks a major breakthrough in China's independent aerospace propulsion development, filling a domestic gap in medium‑to‑large aircraft engine technology. It is optimized for low‑altitude operations in the 5-15 ton class and supports high‑altitude flight up to 20 km (12.4 miles). The engine enables sustained transonic cruise at Mach 0.9, providing strong propulsion for high‑performance UAVs.
The engine incorporates advanced combustion and sealing technologies, allowing for long-duration operation under extreme conditions. It can support single flight missions exceeding 30 hours, making it suitable for strategic reconnaissance, surveillance, and extended‑range drone operations.
The upgraded version of the F918 includes a rights‑managed control system and a health management system powered by intelligent algorithms. These systems monitor engine status in real time, provide fault alerts, and enable automatic fault handling, significantly improving operational safety and reliability.
Tianfu Light Power Technology Co., Ltd., based in Chengdu, focuses on the development of lightweight propulsion systems for aerospace applications. The company plays a key role in China's push to advance domestic jet engine technology, particularly for unmanned platforms and specialized aircraft. Its work supports national efforts to reduce reliance on foreign propulsion systems and expand capabilities in high‑altitude, long‑endurance flight.
