SEPARABLE COMPARTMENT OF THE AIRCRAFT Russian patent published in 2024 - IPC B64G1/64 

FIELD: aviation; rocket technologies; space technologies.

SUBSTANCE: invention relates to systems for separating products of aviation and rocket and space technologies. The divided compartment contains a shell (1), fastened to annular frames (2) with an internal and external annular groove, forming a zone of the smallest annular thickness (length L), in which the inner annular element (5) is mated with electric detonators (ED), annular shelf (7) and a detonating extended charge (DEC) (8). The diameters D of the location of the axes of the fastening holes (9) of the frames, the middle of the smallest annular thickness of the frame (5) and the middle line of the shell thickness are the same. On the frame, symmetrically to the DEC (8) and to a zone of length L, there are two external annular protrusions (10), the distance L₁ between which is determined based on the condition of the stability of the supported shells to axial operational loads. The annular shelf (7) and the element (5) are made in the form of annular segments attached to their annular projections (10). On the annular element (5) there is a groove (11) for the DEC, and the axes of the thruster pass through the middle of the DEC.

EFFECT: reducing stress in the area of the smallest thickness of the compartment frame due to the torque-free transmission of forces from the fastening points through the compartment, as well as reducing the power of the DEC.
