    In terms Development of a new grenade

    to replace RPG-2 was launched in 1958 at the state enterprise "Basalt".

    In 1961, a new launcher, designated RPG-7, was adopted by the Soviet Army.

    Its design was so successful that after adopting it almost never exposed to any significant refinements.
    Grenade launcher consists of the following parts and tools:
    - Barrel with mechanical (open) eye;
    - The trigger fuse;
    - Boikova mechanism;
    - Optical sight.

    Parts and mechanisms

    barrel grenade launcher for guiding the flight grenades and removal of powder gases during firing is a smooth tube in the middle of which is the expansion chamber. Trunk and branch pipe connected thread. Nipple in front of the nozzle is formed in the form of two converging cones, at the rear - with fuse socket tarel protecting breech from contamination. The trunk has a cutout for the front latch grenades top - folding front sight and the sight on special grounds, attached below a trigger mechanism, assembled in the pistol grip fire control to facilitate retention when firing a grenade launcher. On the trunk of the left strap has to install the scope mount. Right mounted swivel belt anchorages with grips and shoulder strap. With the loading RPG-7 / RPG-7D

    In terms

    Active-reactive 85mm PG-7V, created by designers FSUE "SSPE" Basalt ", consists of nadkalibernoy PG-7 grenades and gunpowder (propellant) charge. Antitank grenade PG-7 includes: a head portion with a shaped charge, and conductive cone fairing (the head and bottom parts are connected in a single strand through the cowl and cone), powder jet nozzle with six holes, stabilizer with four collapsible and feathers impeller. Jet length of 250 mm is attached to the back of the head of the grenade. In the engine compartment is reactive charge - a sword of nitroglycerin powder (between the diaphragm and focus), as well as pirozamedlitel igniter of smoky gunpowder (ANC). Flowing out of the nozzle to jet engine propellant gases with a high temperature, not damaged stabilizer nozzle unit is located at the front end of the motor housing (near the center of gravity), and nozzles have a small inclination to the axis of the engine. For a message to garnet initial velocity jet engine when loading joins starting powder charge placed in paper pencil case for protection from moisture and mechanical damage during storage and transport. Stabilizer provides stable flight grenades on the trajectory. Placed around the tube stabilizer belt nitroglycerin powder inside it - the igniter of smoky gunpowder. Stabilizer is on the tube retainer for loading included in the notch on the muzzle of the barrel grenade launcher. In this position, the primer is against the firing pin hole. The flexible tail is bent around the grenade and the stabilizer tube in a position fixed ring. In the impeller located tracer to observe the flight grenades.

    To make a shot, you need to: put the hammer cocked, remove the grenade with fuse and push the index finger on the trigger. Under the action of the mainspring vigorously trigger pivots up and hits the firing pin. The striker moves up, breaking the primer grenades located in the bottom of the jet engine. Beam fire from the primer goes on T-shaped channel, igniting a sample of smoky gunpowder gunpowder and tape. High pressure of gases breaks cardboard core, and gases fill the volume grenade firing chamber. When the pressure in the chamber reaches a certain limit, sufficient for pushing the wad through the foam nozzle grenade begins expiration gases. Appointment firing chamber and the wad is that even before the expiration of the required pressure gases arose under the influence of which the energy of powder gases will be more fully utilized for useful work on post-garnet movement. Since the beginning of the expiration gas grenades forward movement begins on the trunk and its rotation (as a result of the impact of emissions on the impeller). Maximum pressure of powder gases in the barrel grenade launcher does not exceed 900 kg/cm2, which is 3-4 times less than in the trunk of weapons with the shutter closed. Since the beginning of the movement occurs grenades pinned capsule pirozamedlitelya jet engine starts burning zamedlitelnogo composition pirozamedlitelya.

    Departing grenades from the bore by centrifugal force and air flow are disclosed stabilizer blades. After removal from the firing grenades at a safe distance of 15-20 m - from the igniter lights pirozamedlitelya ANC and saber jet engine. The resulting gases ejected from the nozzles dock; starts motor operation. Flowing out of the nozzle of the engine gases create a reactive force that tells garnet extra speed. Engine run time - from 0.4-0.6. During this time the grenade flies 100-120 m (active phase of the trajectory). Speed grenade 120 m / s at the time of departure increases burnout path up to 300 m / s.

    In flight, Rotation

    grenades around its longitudinal axis in flight supported by the oncoming airflow impacts on slants of the stabilizer blades on the impeller and mounted in the rear stabilizer and a few tens of revolutions per second. Stable flight grenades ensured by its tail - four blades stabilizer. Rotation grenades around its longitudinal axis is applied to improve the accuracy of fire, since the rotation of the grenade with reduced impact on the error diffusion in the symmetry of the blades of the stabilizer, and a nozzle block housing grenades, unavoidable tolerances in mass production.

    distance 2,5-18 m from the muzzle of the barrel is cocked fuse - EB is included in the circuit. When meeting with grenades barrier drummer dramatically moving forward under the force of inertia, stabs his sting detonator cap. There is an explosion of the detonator and explosive grenades gap. If the grenade misses the target in 4-6 seconds after the shot is triggered self-killer.

    antitank grenade launcher RPG-7 in combat service two rooms calculation - thrower and assistant grenadier. But the construction of the RPG-7 is so easy and reliable that it can serve and one man.

    Especially for airborne troops has created a variation of the RPG-7D, having split trunk.

    RPG-7D - pipe and pipe suharno connected by pipe sector projections, corresponding recess pipe and fixed assembled latch. This design allows you to parse and add a grenade launcher in preparation for dropping. In addition, the RPG-7D in the trigger mechanism additionally introduced translator with lever and spring bushing and pin, as well as redesigned fuse that eliminates the possibility of a shot in the case of an incomplete connection pipe stem with a socket.

    If he

    RPG-7 over the years has changed very little, the grenade to him have undergone significant growth in combat performance.

    Spectrum ammunition for it is very broad, and includes, besides the cumulative anti-tank grenades, and even high-explosive antipersonnel grenades, thermobaric (FAE), incendiary, and other types of training:

    - PG-7V (7P1) - cumulative.
    Warhead: with cumulative warhead. Weight: 2.6 kg. Caliber: 70.5 mm. Penetration: about 330 mm.
    - PG-7VM (7P6) - cumulative (modernized PG-7V), with higher armor penetration, accuracy and windproof. Upgraded fuse, which became known as VP-7M, his work became more stable. Changes were starting powder charge shot, which became known as the PG-7pm. On the device, the action, handling, packing and color same with PG-7V, but starting powder charges PG-7L and PG-7pm are not interchangeable. Produced until 1976. Leading designer VI Medvedev.
    - PG-7VS/PG-7VS1 - cumulative, with a more powerful charge of Phlegmatized HMX (okfol). In PG-shot stabilizer 7VS were reduced azimuth angles of the blades, leading to a reduction in the speed of rotation of the grenades and reduce cumulative spray jet under the influence of centrifugal forces. Completed fuse VP-7M and powder charge PG-7pm. During 1972-1976 produced shot PG-7VS1, warhead which equips cheaper explosive. Leading designers VP Zaitsev and O. Dzyaduh.
    - PG-7VL (7P16) "Ray" - cumulative, designed to destroy tanks with composite armor. Towards a new grenade was designed fuse enhanced safety and reliability - VP-22 with reduced weight, dimensions. Name in the mining "Ray." Leading designer VM Lenin.
    Warhead: with cumulative warhead. Weight: 2.6 kg. Caliber: 93 mm. Penetration: about 500 mm.
    - PG-7VR (7P28) "Summary" - cumulative, with a tandem warhead. Designed to defeat armored vehicles with dynamic protection. Warhead grenades consists of two coaxially mounted and spaced charges: front (precharge) 64 mm caliber with a piezoelectric fuze and warhead main 105mm. Unlike previous rounds, due to the great length of the warhead stowed shot PG-7VR disconnected by a threaded joint warhead assembly and jet engine propelling (starting) charge. The design of the jet engine and propellant shot PG-7VR similar PG-7VL round, but has some design improvements. For more reliable opening of blades stabilizer, given the slower cranking grenades impeller due to its greater weight, the design of the stabilizer were introduced spring. Leading designer AB Kulakovskii.
    Warhead: a tandem warhead. Weight: 4.5 kg. Caliber: 65/105 mm. Penetration: 600 mm.
    - TBG-7V "Tanya" - shot with a thermobaric warhead (fuel-air explosives). Grenade is designed to engage manpower in the trenches, bunkers, shelters, field type, and other areas in contact with the ammunition inside, as well as at break warhead at distances up to 2 m from the windows or loopholes. Provides defeat manpower within a radius of 10 m To the strength of action, this is comparable to a grenade or mine artillery shell 120mm. Besides manpower, using shot TBG-7V can also marvel at unarmored or lightly armored vehicles. When meeting with the barrier is triggered bottom fuse inertial undermining first igniter-breaking, and then the main charge thermobaric mixture. During the interaction with the target, due to deformation of the shell programmable warhead with the filling, forming a ring shaped charge. As a result, light armored combat vehicle with a homogeneous steel armor 15-20 mm diameter hole is cut 150-170 mm, and through him into a fighting machine recorded the explosion products. In the military machine creates extreme pressure disrupting the hatches with latches. The maximum amount of space in which to create reliably affecting pressure - up to 300 cubic meters. Weight ognesmesi TB - 1.8 kg. Using thermobaric (TB) mixture gives a velocity increment of fragments grenades 1.5 times more than conventional fillers. Leading designer AB Kulakovskii.
    Warhead: thermobaric. Weight: 4.5 kg. Caliber: 105 mm. Damage radius: 200 m
    - OG-7V (7P50) "Shard" ("Pencil") - fragmentation. Designed to suppress manpower, including having personal protective equipment (body armor), located in the open countryside, in shelters and field-type buildings to destroy unarmored vehicles. Creates about 1,000 fragments optimum mass, total lesion area - 150 square meters. Explosive m - A-IX-1 (0.4 kg). A distinctive feature is the absence of a jet engine. Leading designer M. farrier.

    RPG-7 can justly be considered one of the best examples of "artillery little man", which is largely due to both the simplicity of the design and use of the grenade launcher, and the successful creation of a diverse and highly effective ammunition for him.

    High efficiency

    RPG-7 is proved in many conflicts, including Afghanistan, Iraq and Chechnya.
    Wide geography of its combat use in the Middle East, the African continent, South-East Asia, Latin America indicates the reliability of this grenade launcher in any geographical area. It is trouble free in the jungle, alpine, mountain-desert and desert areas - a significant impact in terms of adverse environmental factors.

    RPG-7 for a long time was in service not only of the Russian army, but armies are at least 50 states thus became the most famous and one of the best in the world grenade.

    Production

    RPG-7 has been established in many countries, including Bulgaria, Iraq, China, Romania and others.
