METHOD FOR MOUNTING THE CARGO AND PASSENGER CABIN OF THE HELICOPTER Russian patent published in 2021 - IPC B64C27/04 B64F5/00 B64C1/00 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the aircraft industry, in particular to methods for mounting replaceable cabin modules to a universal carrier, including a helicopter. The method for mounting the cargo and passenger cabin of a helicopter includes preparatory operations on the center section (2) and the bottom (3) of the helicopter, in which two rear bolts (11) fixed on the center section (2) and two internal bolts (14, 15) fixed on the bottom (3) are screwed on one technological guide cone (5). Then the cargo and passenger cabin (1) is installed on a stand, the cabin (1) is placed under the center section (2). The position of the passenger cabin is adjusted (1), the passenger cabin (1) is lifted up and the corresponding bolts and technological guide cones (5) on the passenger cabin (1) are combined with the corresponding holes on the center section (2) and the bottom (3). The passenger cabin (1) is fixed by means of nuts (19) screwed onto bolts (16, 17, 18) free from cones (5). Then all the technological guide cones (5) are removed. The crown nuts (19) are screwed onto the bolts (11, 14, 15), the nuts are tightened and their contouring is carried out.

EFFECT: simplification of the installation process is achieved, reducing the time for the installation of the cargo and passenger cabin on the helicopter.
