The Aero Engine Corporation of China (AECC) has announced the successful maiden flight of its 3D-printed micro turbojet engine, a first for the Chinese aerospace sector. Named Minimalist Lightweight Micro Turbojet, the engine was tested in the Inner Mongolia Autonomous Region in northern China.

AECC Performance Claims

  • Maximum thrust: 160 kg;

  • Altitude: 4,000 meters;

  • Technology: 3D printing (process not officially specified, but most likely laser powder bed fusion);

  • Software: Topological optimization used

  • Weight: significantly reduced thanks to additive manufacturing

Strategic Interest in Additive Manufacturing

Additive manufacturing is becoming a major asset for the aerospace sector. Its advantages include:

  • Reduced component weight, essential in aerospace;
  • Design of complex geometries, impossible to produce with traditional processes;
  • Shorter production cycles, with finer digital control;
  • Optimization of operating costs through overall weight reduction and functional integration.

International Context and Competition

Similar projects are underway in other countries, notably in the United States, where several initiatives are aimed at integrating 3D printing into rockets, satellites and VTOL aircraft. The market is growing fast, with increasing global competition.

A Strategic Statement from AECC

AECC has not released details of the materials used or the exact process, but the organization claims that this maiden flight:

  • Lays a solid technical foundation for the future development of advanced engines;
  • Confirms the potential of 3D printing for drones, aviation platforms and clean energy systems;
  • Represents a milestone in China’s national aerospace strategy.
