METHOD TO ASSEMBLE WING FROM POLYMER COMPOSITE MATERIAL Russian patent published in 2017 - IPC B64C3/26 F16B5/02 

FIELD: transportation, aviation.

SUBSTANCE: invention relates to aircraft industry. Method to assemble a wing from polymer composite material consists in connection of nose, tail middle parts (1,2,3) of the wing by spar booms (4) with upper and lower panels by bolts (7) and nut shapes (6) with floating self-locking nuts from aluminium alloys. At first bolted or bonded-bolted joint of spars (4) and panels (5) of the middle part (3) of the wing is made by bolts (7). Simultaneously they install nut shapes (6) and fix spar booms (4) with panels (5), thus performing and completing assembly of the middle part of the wing 3, and then in the same manner by means of bolts 8. On the remaining part of floating self-locking nuts of shapes (6) they install bolts (8), performing connection of nose and tail parts (1,2) of the wing with the middle part of the wing (3). Bolts (8) are installed into the remaining part of nut shapes (6) in gaps between bolts (7) with nuts of fixation of spars (4) and panels (5) of the middle part of the wing.

EFFECT: invention is aimed at simplification of the assembly process by reduction of process operations.
