Boragh armored infantry fighting vehicle

The Chinese version of the BMP-1 is called the WZ 501. The WZ501 family is a derivative of the the Soviet BMP-1, with a slight reduction in weight and maximum road speed. It features a similar low pressure 73mm gun and the Sagger ATGM, along with six roadwheels per side. The Type 86 IFV is fully amphibious and is fitted with an NBC system and infra-red night vision equipments for commander, driver, and gunner.

China maintains roughly 1,000 Type-86 IFV's in operation.

Variants

  • WZ501 (BMP-1) IFV 73mm gun, Red Arrow 73 (ATGM)
  • WZ503 (WZ501) No turret, taller hull Type
  • WZ504 (WZ501) ATGM Red Arrow 73
  • WZ505 (WZ501) Armored Ambulance - Raised rear compartment
  • WZ506 (WZ503) Armored Command Post (4 radios) Boragh - Iranian-made modification of the Chinese Type WZ 501/503 armored infantry fighting vehicle. It was reported in early May 2002, that three additional variations of the Boragh had been unveiled by the Iranian Defence Industries Organisation (DIO) of Iran's Vehicle and Equipments Group (VEIG). These consisted of a 120mm self-propelled mortar variant, of an ammunition resupply vehicle and of an APC fitted with improved armaments.

The Soviet BMP-1, which was born in 1967, is the world's first tracked mechanized infantry fighting vehicle, and its birth kicked off the development of the Army infantry fighting vehicles worldwide. Infantry vehicle is designed to meet the mechanization of the regiment with the rise of tank operations. It was completely different from any previous armored personnel transport vehicles. It combined the high mobility, protective and firepower of armored combat vehicles.

Before the advent of infantry fighting vehicles, infantry usually moved on foot, by vehicle or armored transport vehicles. These vehicles found difficult to achieve effective cooperation with the mobility, speed, protection and firepower and other aspects of the tank. The advent of infantry fighting vehicles, the end of the thousands of years of infantry walking or riding assault, achieved the real sense of the Army mechanization. At present, infantry fighting vehicles have become the main combat forces of various national forces.

The vehicle known as WZ-501, was put into operation in 1992. It retained the structure of BMP-1, using 73mm smoothbore and red arrow-73 anti-tank missiles. Although it has a simple structure, it featured low cost, good mobility, and the advantages of amphibious combat. But after all, the former Soviet Union 1960s design was unable to adapt to the requirements of modern war environment. In particular, its firepower was seriously inadequate the artillery and missile range was low, the power was small.

The Type 86 infantry fighting vehicles use a power capsule front structure, the middle of the turret, the rear for the crew cabin. As the Type 86 infantry fighting vehicles are light armored vehicles, the design and emphasis on firepower and mobility, so they have weak armor protection. In order to improve the protective force as much as possible, the vehicle body structure was transformed, with its low profile, streamlined, and has a better protection than the general vehicles.

The body, according to the possibilities of attack, has different parts according to different angles and thickness. The material is selected with different thickness of the special alloy steel plate, local use of special aluminum alloy. The whole body has 77 pieces of armor plate welded together. The inclination angle of the head tilt armor is larger, and the power tank cover is an aluminum alloy plate with seven horizontal tendons. In addition to pay attention to improve the armor protection, the vehicle is also equipped with a reliable agent and radiation alarm, automatic shut-off and virus control and other three anti-virus system; the same time with a hot smoke device, fire extinguishing system, to further improve the vehicle's viability.

The power system of the Type 86 infantry fighting vehicle mainly consists of an engine, a transmission system, a mobile system and a steering system. The engine and the transmission are located on the right side of the front of the vehicle. The engine uses V-shaped 120 degrees angle, 4-stroke 6V150 water-cooled direct injection high-speed diesel engine, power 293 horsepower. The engine is characterized by small size, light weight, height of only 770 mm, for the vehicle to achieve low profile to create the conditions, the unit power of about 22 horsepower / ton.

At the same time using the vertical installation, through the main clutch and the axis of the commonly engaged gearbox connected, two planetary steering gear installed in the transmission end, so that the entire power transmission device to form a whole, easy to install and adjust. The main clutch is a single-piece friction clutch, hydraulic control; if necessary, can also be used to manipulate compressed air. The gearbox is a mechanical gearbox with a fixed shaft and a synchronizer shift, with 5 forward gears and 1 reverse gear. Which 2 to 3 files and 4 to 5 stalls with synchronizer, the use of hydraulic servo power control; 1 file and reverse without synchronizer, with mechanical control. The two-stage planetary steering clutch is operated by the steering lever and the hydraulic system to achieve stepless sliding steering, and the side reducer is a planetary type that ensures increased drive wheel torque under compact conditions.

Accomodation is provided for a crew of three, including the driver, gunner and driver. The driver is located on the left side of the front of the vehicle body, with a right-turn open hatch, with three daytime observation periscopes. Night driving can be done with a periscope for infrared night driving instrument.

Steering system uses liquid, gas, mechanical joint, steering steering for the steering wheel. In the process of driving, if the oil circuit failure, the gas can be immediately through the solenoid valve into the working state, to avoid the vehicle out of control. If the oil, gas road failure, the driver can use the mechanical way to manipulate the vehicle, so as to be foolproof. Located to the rear of the driver, there is a forward opening of the vehicle door, which can be rotated, with three periscopes, the middle one for the day and night with a light observation mirror (also available day and night infrared observation mirror - this should be with infrared light).

The Type 86 infantry fighting vehicle the middle of the turret shape is very low. Turret rotation and gun pitch are operated by the console and are manually operated. Turret maximum pitch speed greater than 6 degrees / sec, turret maximum speed greater than 20 degrees / sec. The turret is equipped with a small body of 73 mm low-pressure smooth-bore gun (The Type 86 infantry fighting main source of fire), artillery full weight of 110 kg, a total length of 2.185 meters, the maximum pitch angle of -3 degrees 30 minutes to +30 degrees 30 points, due to low chamber pressure, so the artillery has a simple structure, light weight characteristics.

On the right side of the gun there is a 7.62 mm parallel machine gun, prepared for 2000 rounds; in the artillery and artillery shield with a Red Arrow -73 anti-tank missile launchers; turret bottom of the basket; turret top of the right side with a white searchlight. The gunner is located in the turret, with 4 guns with periscope and a day and night light night vision sight.

The sight daytime system has field of view is 15 degrees, magnification 6X; night system field of view is 6 degrees, magnification 6.7X, night vision distance of about 400 to 900 meters. There are two types of armor and grenade in the sight.

The rear of the body crew cabin can carry eight fully armed infantry, sitting back to sit in the cabin. The middle of the vehicle houses the main diesel fuel tank and electrical support. There are four hatches in the service compartment, two in the left and right, connected to the roof deck by hinges. Infantry off the main entrance for the two cars back door, the two back door also as a diesel tank, left rear door volume of 60 liters, the right rear door volume of 70 liters.

Carrying infantry is not the only way the battle can be fought. In order to facilitate the infantry fighting, in the vehicle body on both sides and left rear door with a total of nine shooting holes and observation aimed at the device for the infantry class shooting. On both sides of the first front of the first perforation for class machine guns, 30 degrees to the front of the vehicle direction. The other 6 perforations are used to assault rifles or submachine guns, with a spherical bearing in the perforation that allows the gun upside down 12 degrees or so and 15 degrees to the left and right. Waste shells are collected in the cartridge case, the powder can be exhausted by the exhaust fan. In addition, the vehicle also has a 40 mm rocket launcher, 10 grenades.

The Type 86-type infantry fighting vehicle, without any preparation, can directly cross rivers, lakes, and water travel with tracks, the speed of 7-8 km. Water should be closed before the doors and windows, open the wave board and raised the air intake, the driver should be replaced by the middle of the periscope gyroscope. Water driving conditions for the wave height is not greater than 25 cm, the flow rate of not more than 1.2 m / s. The vehicle is also equipped with gyro semi-compass direction indicator, in order to facilitate the desert and water to determine the direction of driving.

When loading the artillery must return to the loading position, the time equivalent to the artillery into 3 degrees 30 minutes elevation angle, automatically controlled by the angle controller, firing rate of 7 to 8 rounds / min. If the automatic loading machine fails, it can be manually loaded. The turret is equipped with a 73mm tail stabilized rocket extended range of armor and tail stabilized steel bead grenades each 20, of course, can also be based on combat mission needs.
