Description
Technical field
The utility model belongs to equipment training field more particularly to a kind of controllable safety training antitank grenade.
Background technology
In antitank grenade live grenade throw training process, can all occur safety accident every year, cause serious personnel's economic loss.To the greatest extent
Before live grenade throw, trainee had received certain imitating shell and has thrown training pipe, but still can be by throwing field
In overstretched, generate antitank grenade and the dangerous situations such as slip out of the hand, miscarry, cause antitank grenade drop point too close, explosion accidental injury.
Antitank grenade training of safety problem is all the difficult problems in terms of army of various countries training of safety all the time.Currently, antitank grenade
Live grenade throw method for protecting mainly has：
1. the antitank grenade training method that my army uses is first to carry out imitating shell to throw training, it is laggard to grasp certain skill in soldier
Row live-fire training.During live-fire training, operation generally is carried out in the top of foxhole, by a more rich guarantee of experience
Personnel ensure, once miscarrying, support personnel coorinated training person hides rapidly hides explosion into foxhole.This training effect
Although fruit is close to actual combatization, effect is preferable, when antitank grenade, which occurs, in trainer throws error, if support personnel and training
Person's reaction is not prompt enough, or slips up for the walking direction of miscarrying, may result in accident, there are prodigious safety is hidden
Suffer from.
2. and a kind of training antitank grenade that U.S. army once developed, replace real steel with solid rubber, bomb body is transparent, plays built-in
There is one piece of flashing light operated with 9 voltaic elements, after antitank grenade is launched, timer starts timing, and the flashing light flicker in bullet indicates hand
Fulminating is fried, it might even be possible to indicate which soldier is hit by shocking by electricity.But this antitank grenade is particularly suited in manoeuvre, and
It is non-training.Because this antitank grenade is in appearance with live shell, there are prodigious difference, secondly, in antitank grenade throwing, often caused by
Trainer is since the factors such as psychological stress result in miscarrying, and this trained antitank grenade can not provide the tension of live-fire training, because
And it has a greatly reduced quality on training effect.
3. separately there is a kind of trained antitank grenade to draw fire by word bomb cylinder, thin river sand, the iron powder that turns blue, clay, fireworks explosive, fuse cord Ji
Device feature is constituted, although this dummy round relatively live shell in appearance, is but differed greatly, is lacked on explosive effect
Due live shell experience, still there are no small gaps with live practice on training effect.
Either at home or at abroad, in antitank grenade throws training program, safety and training are not handled properly always
The relationship of effect often excessively focuses on training effect and results in prodigious security risk, or ensured good safety but
The training effect of actual combatization is not achieved.
