FABRICATION OF LAMINAR MONOCOQUE SHAPED TO SINGLE CONTINUOUS SHELL Russian patent published in 2015 - IPC B29C63/00 B23K26/342 B23K101/04 

FIELD: process engineering.

SUBSTANCE: invention relates to production of laminar monocoque structure (versions) and can be used in aircraft and space engineering. First, layer-by-layer electronic drawing of the structure is made. Substrate is placed in vertical plane to build up, layer by layer, the shell with inner structural elements in compliance with said electronic drawing by at least one working laser head. Said head is displaced in vertical plane at vertical feed of wire composed of layers material and along the lengthwise axis of structure being made. In building up, said structure is locked by means of mechanized supports as it is constructed. In building up, built-up section width is varied by translation and lengthwise displacement of laser beam with preset amplitude. In compliance with second version, building up is realized along with the fed of polymerizing resin.

EFFECT: monocoque structure, say, aircraft frame, without single rivet, welding, gluing or use of connectors.
