AIRCRAFT MODULES CONNECTION UNIT Russian patent published in 2019 - IPC B64D1/08 

FIELD: aviation.

SUBSTANCE: invention relates to systems for connecting aircraft (AC) modules. Unit for connection of aircraft modules consists of three cylindrical modules with end frames joined in series with each other by means of threaded pins and nuts. Extreme modules are connected to the carrier by side disintegrating assemblies mounted on the outer surface. On the external surface of the frames of the middle module, oppositely to the lateral disintegrating attachment units, there are two brackets with ledges extending beyond the ends of the middle module. Each ledge is fixed with two screws installed in walls of slots of adjacent modules and oriented perpendicular to plane passing through disintegrating attachment assembly and aircraft axis. In each joint between modules an annular plate is installed, which repeats end surfaces of connected frames with holes for threaded pins. On each surface of the annular plate there are microprojections, wherein one of threaded pins in each module joint is located opposite ledges of brackets, is made by sliding fit.

EFFECT: higher stability of joint to shifts at long sign-alternating loads.
