DETACHABLE AMMUNITION Russian patent published in 2023 - IPC F42B15/00 

FIELD: rocket technology; detachable warheads (DEW).

SUBSTANCE: detachable ammunition contains a cylindrical body (1) with a bottom cut and a blunt nose (2) and a length of 1-5 body diameters (1), a parachute (3) with a round dome, a pole hole (4) and an annular belt (5) connected by slings (6) with a brace (7), an external swivel (8). The diameter of the parachute dome (3) is equal to (2.0-4.0)dmStF(λ ). The distance from the bottom section of the housing (1) to the inlet section of the annular belt (5) of the dome is 5-10 diameters of the housing (1). The brace (7) is connected to the body (1) of the ammunition by means of at least 3 connecting links and a length of 0.7-2.0 of the body (1) diameter. The external swivel (8) is located between the connecting links (9) and the brace (7), the length of which is taken equal to 1.0-3.0 of the length of the slings (6), where St=Xc.t./L is the relative coordinate of the center of gravity of the detachable ammunition; Khts.t. is the distance from the front of the cylindrical body to the center of gravity; L is the length of the cylindrical part of the body; dm is the case diameter; λ =L/dm is elongation of the cylindrical body; F(λ )=1+0.05λ is a function that takes into account the effect of elongation of a cylindrical body with a blunt nose on the diameter of the parachute canopy.

EFFECT: creation of a missile launcher with a parachute with an increased volume and weight of the damaging substance by obtaining the minimum dimensions and weight of the parachute while ensuring the necessary stability and reliable parrying of angular disturbances when separating the missile from the jet engine by eliminating the twisting of the lines.
