An opening (34) for accommodating the front end of the advancing rod (4) is formed on the rear end surface of the warhead (30), and a rack and pinion are provided on the inner bottom wall in the opening (34). A clock mechanism (12) (not shown) built in the main body (12a) for measuring a predetermined time (for example, 2 seconds) is fitted, and the clock mechanism (12) is connected to the rack to be connected to the main body ( 12a) has an operating pin (12b) which is recessed, the operating pin (12b) extending rearward in the opening (34) and being formed in an engaging hole (4b) formed in the front end face of the rod (4). Is fitted to. Therefore, the small diameter portion (4a) of the rod (4) is attached to each warhead after a predetermined time has elapsed from the time when the loading cylinder (F) is separated from the shell (1) of the shell (B) by the timepiece mechanism (12). The warhead separating mechanism (33) is operated by advancing to a position corresponding to the fixing pin (6).

When the electric gun (E) ignites the explosive (D) in the shell (C) of the completed ammunition (A) loaded in the barrel of the tank to explode, the explosive pressure causes the shell (F) and the shell (B)
This causes the shell (B) to be fired from the barrel together with the shell (F), and immediately after this shot, the shell (F) is divided by the wind pressure acting on its front center (F 1 ). Is separated from the shell (B), and only the shell (B) flies toward the shooting target. During the flight of this shell (B), the rotary auxiliary wing (44) receives wind pressure and rotates relative to the ammunition body (1), and with the rotation of the rotary auxiliary wing (44), the front end of its base (45) The male screw part (47) and the female screw hole (43) in the fixed blade (40) are loosely screwed together, and the rotation assisting blade (44) retracts with respect to the fixed blade (40).

Then, when a certain time has elapsed from the firing of the cannonball (B) and the cumulative number of rotations of the rotary auxiliary wing (44) reaches a predetermined value,
The male screw part (47) of the rotary auxiliary wing (44) is the fixed wing (40).
The parachute member (14) connected to the rotary auxiliary wing (44) is separated from the fixed auxiliary blade (40) by slipping out from the female screw hole (43) inside and the rotary auxiliary wing (44) is separated from the fixed blade (40). ) Is pulled out from the inside of the opening (13) by the urging force of the push-out spring (16) and expanded by the wind pressure, and the bullet (1) is spread by the braking effect of the open parachute member (14).
That is, the shell (B) suddenly stalls and falls.

Also, in parallel with the expansion of the parachute member (14),
By separating the bullet loading cylinder (F), each ejection pin (10) of the bullet body (1) is ejected to the outside of the bullet body (1) by the urging force of the spring (11), and the rod in the rod insertion hole (3). The lock on (4) is released. Along with this, the rod (4) receives the biasing force of the warhead separating spring (8) and moves forward while receiving the movement resistance by the clock mechanism (12) in the warhead (30), and is set by the clock mechanism (12). After a predetermined time has passed, the small diameter portion (4a) of the rod (4) reaches a position corresponding to each warhead fixing pin (6), and by this positioning, the warhead fixing pin (6)
The movement restriction by the outer circumference of the rod (4) of the above is released, and the warhead fixing pin (6) is retracted into the rod insertion hole (3) by the urging force of the spring (7) and the warhead (30) and the projectile (1). And the warhead (30) is separated from the bullet (1).

Therefore, in this case, when a certain time elapses after being fired from the barrel, the parachute member (12) automatically expands from the bullet (1), the bullet (1) stalls and falls, and the bullet ( Since the warhead (30) is separated from 1), even if the shell (B) flies without hitting the target, or if it rubs against the target and jumps, the shell (B) Can be automatically dropped, so that the cannonball (B) can be reliably prevented from flying to an area away from the target.

In the above embodiment, the parachute member (12) is expanded after a certain time has elapsed from the firing of the cannonball (B) to stall and drop the cannonball (B), and the warhead (30) is used as a bullet ( Although it is separated from 1), only the parachute member (14) may be expanded. However, it is preferable to separate the warhead (30) as in the above embodiment because the effect of preventing the flight of the cannonball (B) from other than the target can be obtained more reliably.
