China’s Aero Engine Corporation (AECC) has successfully conducted the maiden flight of its 3D-printed minimalist turbojet engine, demonstrating a major breakthrough in advanced propulsion technology.
The 30-minute flight powered a drone to 6,000 meters and a speed of Mach 0.75, with stable performance throughout. Over 75 percent of the engine’s components by weight were 3D-printed, reducing part count and achieving high efficiency and lightweight design.
Experts highlight the cost-efficiency and rapid production capabilities of 3D-printed engines, making them ideal for drones, loitering munitions, and other platforms that require large-scale, expendable use in complex operational scenarios.
AECC officials said additional flight tests are planned to examine performance under extreme conditions and optimize processes for mass production, ensuring reliable application in future aerospace and defense systems.
This success underscores the potential of 3D printing to revolutionize engine manufacturing, combining innovation, speed, and scalability for modern aviation and unmanned systems.
