The 40-mm shot VOG-25 (7P17) is unitary in its design and is made according to a "sleeveless" scheme, i.e. the propellant charge, together with the means of ignition, is located in the bottom of the grenade body. Shot grenade - fragmentation grenade with a steel case. Inside the grenade body there is a grid of cardboard for rational crushing of the body into fragments. The grenade fuse is a head, percussion, instantaneous and inertial action, semi-safety type. The cocking distance is from 10 to 40 meters from the muzzle of the grenade launcher. This spread depends on temperature range(from -40 C to 50 C). The response time of the self-liquidation mechanism is 14-19 s.
Slide 19
40 mm shot with fragmentation grenade VOG-25P ("Foundling"). An expelling charge and a pyrotechnic retarder were introduced into the design of the VMG-P fuse, providing a "bouncing" of the grenade after hitting the ground and its rupture in the air when firing at all ranges combat use grenade launcher. The height of the grenade burst when firing at the ground of medium hardness was 0.75 m, which made it possible to increase the efficiency of the fragmentation action in comparison with the VOG-25 grenade: - at lying targets by 1.7 times; - for targets located in the trenches by 2.0 times.

Hand grenades: purpose, types. A grenade is an explosive weapon designed to
destruction of enemy manpower and equipment with the help of
hand throw.
A modern hand grenade consists of a body,
explosive charge and fuse (fuse).
The defeat is inflicted by fragments of the hull,
shock wave or cumulative jet, and
also, as an option, ready-made striking
elements (shrapnel). Made from
light alloys, materials of high specific
strength and plastics.
A trained soldier throws a fragmentation
grenade at 40-50 meters, anti-tank -
about 20 meters.
Fuse
Grenades may have a fuse,triggered on different principles of detonation
- dynamic (detonation upon impact with the target),
or with a delay (detonation by a fuse with
given delay).
Undermining with a delay is carried out
as follows: when pulling out
safety pin and clip release
cocked in advance
spring mechanism, and the striker hits with force
per capsule from shock-sensitive
substances, (by analogy with the product
hand-held shot firearms).
UZRG
Exploding capsuleignites gunpowder in a thin fuse
tube. Gunpowder burns at speed
approximately 1 cm per second and does not require
oxygen, so the grenade can
explode underwater. When the fire is in
ignition tube reaches the detonator,
it explodes and causes detonation
explosive, which
equipped with a grenade.
Depending on the design,
the fuse of the grenade turns on the fuse
a tube with a primer and a detonator, and
may also include a spring
mechanism with striker, pin and trigger
bracket.
Classification

Among the hand-held anti-personnel grenades are:
Among hand anti-personnel grenadesallocate:
defensive grenades with a large radius
damage (more explosive power, quantity, quality and
fragmentation distance).
Defensive grenades are supposed to be used only because of
shelters, otherwise they are dangerous for the grenade launcher himself.
A typical defensive grenade - F-1 (explosive charge -
trotyl, 60 g; weight 600 g);
offensive (small explosive charge, scattering of fragments and
damaging effect). Offensive range
pomegranate guaranteed smaller medium range throw
hand, so they can be used while in the open
space.
Offensive includes, for example, RGD-5 (charge
BB - TNT, 110 g; weight 310 g.).
F-1 grenade
F-1 - manual anti-personnel defensivegrenade.
defensive battle.
Due to the significant radius of fragmentation
you can only throw it from behind cover, from
armored personnel carrier or from a tank. The F-1 grenade has the following tactical and technical
characteristics.
Throw range: 50-60 m
Fragment damage radius: 7 m
200 m - safe distance
Ignition deceleration time: 3.2-4.5 sec
Number of fragments up to 300 pieces
F-1 grenade refers to hand-held anti-personnel fragmentation
defensive remote-action grenades.
Its design turned out to be so successful that without
fundamental changes have existed up to the present
time. Several changes and improvements were made to
increase the reliability of operation of the design of the fuse.
Like most anti-personnel grenades, the F-1 consists of 3 main parts:
Fuse. The grenade has a universal fuse UZRGM (or UZRG). fuseUZRGM differs from UZRG by changes in the shape of the trigger guard and
striker design, which made it possible to reduce the failure rate of weapons.
Explosive. Explosive charge - 60 g of TNT.
Such grenades have an increased lethality, but the duration
storage in warehouses is strictly limited, after the expiration of the grenade
represents a significant hazard.
Metal shell.
Externally, the grenade has an oval ribbed
cast iron body.
Slicing the body makes it easy to tie
grenades to the peg and also performs
ergonomic function, contributing to
better holding grenades in hand.
The total weight of a grenade with a fuse is 600 g.
RGD-5 (hand grenade, remote)
RGD-5 - Soviet offensive manual
grenade, refers to anti-personnel fragmentation
remote hand grenades
offensive type. This means that she
designed to damage personal
the composition of the enemy with fragments of the hull with his own
explosion.
The grenade reaches its target by throwing it with the hand.
Remote action - means that the grenade
will explode after a certain time (3.2-4.2
seconds) after it is released, regardless
from other conditions. offensive type -
means that grenade fragments have a small
mass and fly at a distance less than
possible throw distance. Externally, the grenade has an oval body made of thin steel.
The streamlined body is assembled from the upper and lower parts,
each of which includes an outer shell and an insert.
Igniter hole closes during storage
plastic stopper. .
Explosive charge - TNT weighing 110
grams.
The range of fragmentation is 30 meters.
The fuse of the grenade is universal, suitable also for
grenades RG-42 and F-1.
Brand fuse: UZRG, UZRGM (since the second half of the 1950s
years), or UZRGM-2. All of these fuses are interchangeable.
Mass of a grenade with a fuse 310 g
RGO (defensive hand grenade)
RGO (defensive hand grenade) - hand
anti-personnel defensive strike-remote.
Designed to defeat manpower in
defensive battle. The grenade is delivered to the target only
due to her throw with the hand of a soldier.
The radius of destruction by fragments of a grenade is 50 meters, the radius
possible defeat 100 meters. According to performance characteristics in general
similar to the F-1 grenade, but unlike it has
combined shock-remote fuse.
Self-destruction time 3.2-4.2 sec.
Long-range cocking time 1.3-1.8 sec.
Weight 530 g
Detonation mechanism: UDZS fuse with
deceleration time 3.2-4.2 sec. A grenade explosion occurs when a grenade meets
surface. For the fuse, it does not matter which
part of the grenade hit the surface. Has the meaning
only the deceleration speed of the grenade when meeting with
surface.
In order to improve the safety of the grenade launcher during
random encounter of a grenade with an obstacle at close range
distance from the grenade launcher, the fuse is cocked
only after 1.3-1.8 sec. after being released
safety lever (grenade thrown). That is, if
the grenade at this time will hit something, then the explosion will not
will happen at all.
If the grenade explosion did not occur from a percussion fuse
actions (grenade is not thrown, but the lever is released; grenade
is still in flight; the grenade fell into the water or
loose snow) then after 3.2-4.2 seconds after
the safety lever is released, the
self-destruction of a grenade by its detonation.
RGN (offensive hand grenade)
RGN (offensive hand grenade) anti-personnel
fragmentation shock-remote.
Designed to defeat manpower in combat.
The radius of destruction by fragments of a grenade is 15 meters, the radius
possible defeat 35 meters.
The RGN fuse is cocked only 1.3-1.8 seconds after
when the safety lever is released.
Weight 290 g
Detonation mechanism UDZS fuse with deceleration time
