As a new idea and technical method

digital twin has become an important starting point for enterprises to implement digital transformation strategy. Combined with the development characteristics of aero-engine in China and the application status of digital technology in the industry

an application framework of digital twin technology for aero-engine development is proposed

and the digital twin element application modes of process design

production and manufacturing

product assembly maintenance support. And digital twin applied technology is researched and analyzed on the MBD-based manufacturability analysis

digital process design simulation

virtual manufacturing

virtual assembly delivery

remote maintenance

etc.

which provides digital capability for the advancement of aero-engine development.
