In the background of that: the new round science and technology revolution and global industry upgrading is expeditiously advancing

the innovation-driven development is erected as state strategy by China and traditional equipment manufacturing industry is under transformation and update

how to realize the transform of the aero-engine assembly from the traditional manufacturing mode characterized by labor-intensified and experience-dominated to the advanced manufacturing mode characterized by digitization

automation and intelligence

increase the assembly accuracy

consistency

reliability and efficiency at upper level

create more and larger value of final manufacturing in the product life cycle

it is not only an important strategic development issue for aero-engine industry

but also a commitment for the ‘pearl on industry crown’ to lead as a model for assembly manufacturing upgradation of other high-tech equipment product. Based on the aero-engine assembly process technology development condition

this paper presents the main gap between China and other country

analyzes the issues wherein

refines the research requirement of fundamental technology and engineering application technology

makes the prospect and suggestion for later assembly technology development. Hopefully

this paper provides the enlightenment and reference for aero-engine assembly process optimization and upgradation

related R D project planning and establishment.
