DEVICE FOR CONNECTING SEPARABLE ELEMENTS OF AN AIRCRAFT Russian patent published in 2022 - IPC B64G1/64 

FIELD: aviation, rocket and space technology.

SUBSTANCE: invention relates to the field of aviation and rocket and space technology and can be used in the design of various separable systems and devices. The device for connecting separable elements of the aircraft contains a compartment with a frame with a detonating elongated charge with a cumulative recess and electric detonators, an inner and outer casing, consisting of two mutually overlapping parts. In this case, the frame of the device is provided with an outer annular flange, and on the inside it is provided with a transverse annular flange directed to the axis of the compartment and perpendicular to it, on the inner side of the frame in the shelf an annular groove is made in the zone of the smallest annular thickness of the frame. The detonating elongated charge is placed in the groove, with the nominal position of the cumulative recess directed towards the smallest annular thickness, and the device itself is additionally equipped with an internal annular element in contact with the transverse annular shelf, and two external half-rings jointly fixed on the frame of the device. In this case, the electric detonators are installed on the inner annular element.

EFFECT: proposed device provides an increase in reliability in terms of preventing unauthorized operation of the device when exposed to gas-dynamic and aerodynamic heating of structural elements.
