Determinate/determinant assembly (DA) adopts the part-to-part connection scheme

reducing the use of the jigs and fixtures

avoiding the work of shimming

fettling and final-hole-size drilling

which is gradually employed by the aircraft assembly. With the extensive application of composite materials in aircraft monolithic component

full-size determinate assembly (FSDA) is being studied and experimentally applied. Firstly

the state-of-the-art and the development of aircraft determinate assembly technology at home and abroad are reviewed. Then

the key technologies for aircraft determinate assembly are summarized

including model-based definition

assembly process optimization based on digital twin technology

tolerance prediction and statistical analysis

flexible tooling technology. Finally

a technical scheme of full-size determinate assembly was proposed for the composite panel assembly.
