DEVICE FOR DETACHABLE CONNECTION OF HOUSINGS OF AIRCRAFT COMPARTMENTS Russian patent published in 2024 - IPC B64G1/22 B64G1/64 

FIELD: machine building.

SUBSTANCE: invention relates to aircraft engineering. Proposed device comprises butt-jointed docking compartment and detachable compartment. They are connected by means of two or more cylindrical segments with symmetrical inner conical surfaces. On the segments there are symmetrically arranged threaded holes. Pyrobolt with an electric detonator is installed in the central threaded hole. There is an annular projection on the detachable compartment, which extends higher in diameter to the annular projection of the docking compartment, which is flat in the area of installation of explosive bolts. In the annular projection of the detachable compartment, in the installation zone of each explosive bolt, a recess is made, in each cylindrical segment there is a central cylindrical hole and an external cylindrical recess. Device is additionally equipped with bushings and nuts threaded on each explosive bolt. Each bushing is placed in the central cylindrical hole of the cylindrical segment and contacts by its end surface with the surface of the docking compartment. Nut is placed in the outer cylindrical recess of the cylindrical segment.

EFFECT: higher reliability.
