APPARATUS FOR CONNECTING THE HULLS OF COMPARTMENTS Russian patent published in 2022 - IPC F16B2/06 B64C1/32 

FIELD: aviation.

SUBSTANCE: invention relates to the field of general mechanical engineering, namely, to systems for detachable connection of the hulls of compartments of an aerial vehicle. The system comprises two or more cylindrical segments with symmetrical internal conical surfaces coupled in the plane of the joint with the outer surface of the frames of a pair of butt-connected compartments, wherein one frame comprises an annular ledge with holes for the threaded connections provided to secure the joint; the joints themselves are at the ends of the segment, with axes thereof passing along the coupling surface perpendicular to the axes of the compartment hulls. The threaded connections provided to secure the joint are made as explosive bolts with an electric detonator, a nut, and a washer; the bolts are installed on the inside of the compartments in the holes of the frame with an annular ledge, recesses are made on the outer surface of the frames in the area of the holes for each bolt perpendicular to the axes thereof, and the cylindrical segments are equipped with threaded sleeves with collars mounted on the segments coaxially to each explosive bolt enabling axial movement thereof and coming in contact with the surface of the frame recesses; wherein the end surface of each sleeve is matched with the separation plane of the bolt, and each washer for a bolt fastening nut is provided with an annular protrusion in the inner diameter of the sleeve.

EFFECT: higher reliability and improved operating characteristics of the system due to the fault-free operation of the explosive bolt and the reduced disturbance to the structural elements of the aircraft.
