Introduction of RPG-7

abstract

With the continuous improvement of the armor performance of the world's main battle tanks, the рпг-2 rocket launcher equipped by the former Soviet Union has obviously insufficient power, short range and large flame, and can only shoot on the right shoulder. Therefore, in the late 1950s, the Soviet Union developed the рпг-7 40 mm rocket launcher. This is a new anti-tank weapon developed on the basis of рпг-2. Its launching principle, caliber, sight, launching and firing mechanism are the same as рпг-2, but the barrel structure is improved, the main optical sight and the rocket extended range engine are added, and the warhead is redesigned. The penetration thickness of the matched пг-в and пг-вм armor-piercing projectiles to the rolled homogeneous armor is 350 mm and 400 mm respectively, and the direct distance is 300 mm. In addition, it is equipped with ог-7 anti-personnel Grenade to enhance its combat function.

The rocket launcher was mass-produced around 196 1 and reached 1966, completely replacing the рпг-2 type and becoming the standard anti-tank weapon of infantry squad. In addition to the Soviet army, it also equipped a large number of troops from Warsaw Pact countries, Arab countries, African countries, the Middle East, Asia and many other countries. 1968, Soviet airborne troops were also equipped with a collapsible рпг-д 40mm rocket launcher.

1992 10 From June 6 to June10, two new types of ammunition рпгвв-в were also exhibited at the Seventh National Defense Weapons Expo held in Athens, Greece: one was an assault Grenade; The other is a series warhead rocket extended-range armor-piercing projectile with a caliber of 105mm, a mass of 4.5kg and an effective range of 200m·m m. It is said that it can destroy all kinds of modern tanks, including the main battle tank equipped with reactive armor, and can penetrate reinforced concrete with a thickness of 1.5 m, and the penetration thickness of field fortifications of civil structures is as high as 2.7 m or more.

design feature

рпг-7 rocket launcher has the advantages of thin wall, small mass, great power, long range, small afterspray flame, strong and durable structure, and can be fired from left and right shoulders.

A rocket launcher consists of a launcher, a sight, a handle, a guard plate, a shoulder strap, two end sheaths, a handle, a launching mechanism, a firing mechanism and a safety device. The launcher is made of alloy steel, including barrel and nozzle. The front end of the positioning pin of the rocket has a notch, and the rear end has a guard plate to prevent debris such as mud and sand from blocking the tail nozzle when accidentally landing. The upper part of the barrel body is provided with a quasi-constellation and a ruler seat, and the lower part is provided with a handle connecting ear, a handle fixing convex wall and an injection seat chamber; The left side of the barrel body is provided with an optical sight fixing plate, and the right side is provided with two fixing straps and a shoulder strap ring; The wooden guard board is fastened with guard board hoop, which plays the role of heat insulation. The launching mechanism is located in the handle. The firing mechanism consists of a rebound needle striking component located in the cavity of the needle striking seat, and the safety mechanism is used to lock the trigger to prevent firing.

The early locking mechanism was wire rope type, and later it was changed to lever locking machine. Because the transfer button with lever and spring is adopted in the launching mechanism, and the structure of the safety device is changed accordingly, the trigger can be automatically in the safety state before the tail nozzle part and the barrel are combined in place. When disassembling, the left hand holds the barrel, the thumb presses out the lever of the locking mechanism, and the right hand unscrews the tail nozzle assembly counterclockwise, then folds it under the barrel and fixes it with the locating pin and spring bracket, thus becoming an airborne container weapon. If you need to use the night vision sight, you can install a bipod between the quasi-constellation and the grip.

2. Sight

The rocket launcher adopts an optical sight mainly for aiming and measuring, with a magnification of 2.7 times and a field of view of 13. On the crosshair of the sight, there are four horizontal lines with corresponding distances of100m, 200m, 300m and 400m respectively.

In addition, the rocket launcher is also equipped with a folding mechanical sight; Low light sight and infrared night vision sight, used in starlight or other low light conditions.

3. Ammunition

Rocket launches пгв and пгвм extended-range armor-piercing projectiles, including hollow charge warhead, вп-7 piezoelectric fuze, rocket engine and tail assembly. The propellant tube is screwed behind the rocket engine, and the tail tube, tail wing and turbine of the tail wing assembly are contained inside. The warhead has a mass of 866g and contains 388 Ga-ⅸ- 1 explosive. The fuse head mechanism is screwed into the hood insulation sleeve, and the hood insulation sleeve is equipped with a protective cap to prevent the piezoelectric element from being accidentally hit in use. The bottom mechanism of fuze with delayed self-detonation device is located behind the explosive. The rocket extended-range engine adopts single-hole tubular double-base propellant.

The пг-вм rocket is an improved version of the пг-в missile, with a diameter of 70.5mm, a slightly smaller weight, and strong armor-piercing ability, shooting accuracy and wind deflection resistance.

In the пгв. In addition, the ог-7 anti-personnel Grenade with the same caliber was developed, with a fighting length of 250mm, a trigger fuse and a killing radius of15 mm.
