The present invention relates to a 40mm practice bullet for marking a landing site of a grenade launcher, and more particularly, to identify the landing site easily by continuous smoke smoke caused by an explosion of a warhead during shooting training on a target landing site with a grenade launcher. And a 40mm practice bullet for marking a landing site of a grenade launcher that can be used for signaling purposes.

In general, 40mm grenade (high bomb) is a type of military weapon that can kill lives, destroy light armored vehicles, and serious positions by using a grenade launcher, and the 40mm grenade (high bomb) for the same training effect when training. A 40mm drill is used instead.

Looking at the state of use of the conventional 40mm drill grenade as follows.

First, when the ball hits the primer 2 provided on the casing 1 side in the state where the grenade launcher is equipped with a 40 mm exercise grenade, the propellant 4 is combusted.

When the propellant 4 generates a propellant gas by instantaneous combustion and flows into the casing 1, the propellant 4 launches the warhead 5 at the expansion pressure of the propellant gas, and the warhead 5 collided with the landing site is impacted. When the ball 6 hits the primer 7 by the explosive force of the primer 7, the detonating agent 9 filled in the head body 8 explodes, destroying the injection warhead 5, causing the detonation and binge drinking. By the combustion of the ninth, an instant smoke film is formed. Reference numeral 3 in the drawings is a primer housing for receiving the primer 2 and the propellant (3).

However, the conventional 40mm exercise bomb has a problem that it is difficult to determine whether the trainee hit the target impact point accurately by the instantaneous smoke generation. In particular, when the wind is severe, there is a problem that it is more difficult to identify the impact point.

The present invention is to solve the problems as described above, in order to enable the continuous smoke smoke, the smoke emitting space in the inside of the smoke pipe to secure the space and the contact area between the lead wire and the ignition agent by bending the ends of the pair of wires The purpose of the present invention is to provide a 40mm exercise cartridge for the grenade launcher's impact point marker that increases the ignition power, maintains the combustion of smoke agent uniformly, prevents discoloration of smoke smoke, and smokes.

The sink 224 is released from the restraint of the safety pin 226, but does not strike the detonator primer 223 due to the setback action of the sink spring 225 and the sink.

3. Collision of the target impact area.

When the warhead assembly 200 is flying and collides with the target landing place, the ozave 240 is destroyed, and by the law of inertia, the sinking 224 overcomes the elastic force of the sinking spring 225 and continues to advance, thereby detonating the detonating primer ( 223).

The detonator primer 223 ignites the ignition agent 223, and the first and second conductive lines 234 and 235 ignite the ignition agent 223. At this time, the first and second conductive lines 234 and 235 are perfectly ignited even by small ignition by the ignition parts 234b and 235b in contact with the ignition agent 223.

The combustion units 234a and 235a of the first and second conductive lines 234 and 235 burn the smoke agent 232 while igniting.

Combustion portions 234a and 235a of the first and second conductive lines 234 and 235 are configured to have different lengths, so that after the combustion of the combustion portion 235a of the second conductive line 235 is finished, the combustion portion of the first conductive line 234 ( 234a) continues. Accordingly, the inside of the smoke pipe 232 is burned only by the first conductive line 234, so that the discoloration phenomenon of the smoke agent 232 does not occur.

The smoke screen by the smoke agent 232 is discharged through the smoke hole 231a via the smoke discharge space 231b behind the ignition agent 233, and the smoke monitor visually checks the smoke screen in a training bottle or an observer or an aircraft.
