NFV-1 infantry fighting vehicle
In June 1986 NORINCO negotiated with the American Food Machinery Corporation (FMC), and agreed to use the 86-type track infantry fighting vehicle chassis and the US FMC 25mm (M242 type) single electric drive turret, jointly developed NFV-1 infantry Chariot. The prototype was officially exhibited at the Beijing International Defense Exhibition in 1986, followed by driving and live-fire shooting at the Beijing test site. In September 1987, at the invitation of Egypt, it participated in the International Defense Exhibition held in Egypt in November 1987, and conducted a comprehensive vehicle performance and shooting test.
The NFV-1 inherited from the Type 86 infantry fighting vehicles a dexterous, smooth, elegant structure, the chassis was streamlined, shape is very low, front like a sharp knife, its beautiful posture is still so compelling. NFV-1 vehicle and the biggest difference between the Type 86, that is, from the original round-shaped turret for the square wedge-shaped turret, the gun from the original short and thick 73 mm caliber artillery, for the new 25 mm small caliber machine gun, Turret slender and sophisticated; then the turret "Red Arrow" 73 anti-tank missiles have also been canceled, the turret is more clean and neat.
The vehicle mounted a new turret, its beautiful shape closer to the world's mainstream infantry fighting the elegant design, more in line with people's modern infantry fighting aesthetics. In addition, the vehcile had another significant feature, that is, the location of the machine gun significantly on the right, with the general infantry fighting vehicles in the middle of the installation of the turret in the center of the formation of a sharp contrast. The following focus on the vehicle that the unique combination of Chinese and Western taste.
The chassis inherited the excellent structure of the Type 86 as the Type 86 with a low body, the body streamlined, motor speed, easy operation and many other advantages, therefore, in the joint development process, the chassis part is basically intact. To adapt to the US turret, the original turret seat was changed directly to the chassis of a loaded, basically completed this piece of Chinese and Western "works".
It can be said, NFV-1 vehicle chassis is the same as the authentic Type 86 chassis. The overall layout of the chassis is this: the whole vehicle for the three crew, eight players, the crew were the driver, coach, gunner (still single turret structure, gunner also known as gunner); The staff consisted of two classes of machine gunmen, a 40-mm rocket launcher, and five assault gunmen (the original Type 86 had an air defense missile, which was replaced by a submachine gunman). Of course, if exported abroad, the set of players may be different. The vehicle is divided into cab, vehicle room, power transmission room, fighting room, left infantry room and right infantry room.
The cab is located on the left side of the front, the power transmission chamber on the right side of the front, separated by a composite panel (the partition has good sound insulation, heat insulation and sealing performance), the fighting room in the middle of the body. The gunner in this operation machine gun and parallel machine gun (the original vehicle for the 73 mm artillery and anti-tank missiles).
The car's carrying room has two distinctive features compared to other armored vehicles. First, it does not use a large loader's structure, but divides the rear space of the vehicle into two left infantry and right infantry seats. The second is the general armored vehicle infantry is sitting face to face, and the vehicle is back to back sitting, the advantages of this method of sitting is easy for infantry in the vehicle to shoot. The downside is that the cabin is separated and the interior space is very small. In the two infantry rooms installed between the group of diesel fuel tank (main fuel tank), batteries and distribution boxes and other components, in order to facilitate the maintenance of batteries and the use of external power supply, distribution box installed in the door by the location.
There are 3 daytime periscopes in the range of about 120 degrees in front of the top of the cab, and the periscope can be changed to night vision and floating catapult. In the first corner of the vehicle is equipped with a night vision device to match the infrared headlights. The driver's window can be lifted and turned, the driver can use a special protective cover when driving, so as to avoid the dust of the pain (59 tank driver driving up, only the front of the car, if followed by other cars, There is only "eat soil suffer" copies of the). The position of the driver's chair can be adjusted as needed fore and aft.
There is a rotatable 360-degree window in the vehicle room with a forward-opened vehicle door, which is equipped with a car's day / night view mirror (for a low-light or infrared ), The left and right sides for the daytime periscope. When using the active infrared night vision, but also in the vehicle window window to install a tilt adjustable infrared headlamps, used to provide infrared light source. The left side of the vehicle room is the radio and the vehicle on the 1st phone, the radio behind the three anti-device room and heating equipment room. Most of the components of the driver's seat are common to the driver's chair, but the position can not be adjusted and the seating is a little uncomfortable.
In the power transmission room is installed the drive assembly, the engine and its auxiliary system, the exhaust ejector and the air filter, the automatic fire extinguishing system flame sensor, the front electric drainage pump and the engine driven drainage pump and various pipelines Wait. The engine and the drive are integrated. The ventilator is above the power chamber and its operating mechanism is mounted on the partition of the vehicle room. Below the blinds are the exhaust ejector, the oil radiator and the water radiator.
The combat room has the turret, circuit rotary connector, 25 mm machine gun and parallel machine gun, turret bi-directional stabilizer, manual high and low machine and direction machine, turret basket, shell box (including bomb device), machine guns As well as gunner seats and so on. Left and right infantry room at the top of each have two top windows, can be opened and locked in the vertical position. Left and right infantry room each have four shooting holes, the top of each have four fixed daytime periscope, which is the first shot hole is a class machine gun shooting hole, and a gun rack, all shooting holes by the hole cover, hole Seat and spherical observation mirror with gun eye.
Each shot hole is also equipped with exhaust fan discharge. Each infantry room has a rectangular four-seat seat. After the vehicle with two fuel tank with the back door (can be locked in the vehicle with the hand wheel, the back door closed after the driver's lights off), the left rear door has a shooting hole and a daytime periscope, right rear door there is only one daytime periscope. The power of the vehicle is a 6V150 four-stroke water-cooled direct injection high-speed diesel engine (code WA701), power 215.5 kilowatts (293 horsepower), mainly to start the air, electric start supplement.
In order to protect the vehicle when the engine water, the designer in the engine exhaust pipe installed a waterproof valve, when the water hit the door, the valve will automatically shut down, play the role of anti-water. The exhaust ejector and air cleaner are integrated, and the ejector is equipped with two side-by-side nozzles for pumping dust from the bottom of the air cleaner. As with the 59 tanks, the vehicle is equipped with a heating pot (automatic, manual), the winter with it on the engine heating.
In addition, the vehicle is also equipped with two heating devices, the use of the engine cooling water to the vehicle room and the crew room heating. The two heating units for the tube structure, open the heating switch can be heated. 2 heating 1 installed in the three anti-device room for heating the booster fan pumping in the fresh air, in the use of three anti-device can be given to the whole vehicle heating, when not used to the driver and vehicle length heating; another 1 A heating device is installed near the distribution room of the carrying room for heating the battery and for heating. This 2 heating there is an alternative usage, that is, as the engine auxiliary radiator.
With the vehicle in summer overheating phenomenon, the crew can open the two heating, the engine cooling, but the three anti-device room and the crew room temperature will rise sharply, the crew will be hot, and cannot stand the heat, so this The method can only be used for short-term cooling of the engine. The vehicle is also equipped with a KY-8 air compressor, for the whole vehicle to provide compressed air.
The transmission of the vehicle is integrated mechanical, including the double-piece dry friction main clutch, with a synchronizer (except gear, reverse gear) fixed shaft gearbox, two-stage planetary steering, double-belt floating brake , Drive shaft and a planetary side reducer. The gearbox has five forward gears and one reverse gear. Steering steering for steering wheel. The main clutch is separated, the second gear of the fifth gear shift, steering, parking brake are used hydraulic control; a file, reverse gear shift, hand brake, foot throttle and hand throttle are mechanical control. Main clutch, gearbox, steering gear, parking brake and the main hydraulic components for the integration of the structure.
The car's drive system adopts single torsion spring suspension device, cylinder type hydraulic shock absorber, overall forging type balance elbow, single wheel hanging hanging small load wheel, hanging plastic aluminum alloy carrier pulley, Pin forging track plate, tooth surface spray or surfacing a layer of wear-resistant alloy, such as the driving wheel. Driving wheel front, induction wheel rear, the vehicle has six load wheels on each side, two shock absorbers and three carrier wheels, each with 84 track shoes.
From the armor protection performance point of view, the vehicle compared with other combat vehicles is also quite good: the body is made of steel armor plate and welding method; first armor by the drive compartment cover (for the aluminum alloy armor shaped plate Structure, with ribs on it to improve the ballistic resistance and structural rigidity), power chamber cover (aluminum alloy structure), blinds, driving windows, vehicle window and other connected armor plate, these components together into the formation of Good protective performance of the vehicle first armor system. And Type 86 is different, the turret using composite armor, the specific material is unknown.
In order to improve the crew capacity of the crew and the crew, the inner surface of the various parts of the vehicle and the inner surface of the doors and windows are covered with a 10 mm thick lining. The main component of the lining is lead-containing polyisobutylene rubber compound, effective combination with the armored body, can effectively prevent the killing of nuclear radiation. According to the experts, armored body on the nuclear radiation plays a major protective effect, the nuclear radiation dose can be reduced to one tenth of the following, and the role of lead-containing lining is to enhance the effect of anti-nuclear radiation.
In addition, the lining can be a multi-purpose, in addition to anti-nuclear radiation, but also on the body for effective insulation shielding, when the vehicle air conditioning (heating) work, you can greatly save energy; Lining can also act as a "protective pad", to protect the crew in the vehicle hit the body suddenly hit the bumps and injuries. But it is hard to see how this little liner could have such a magical "effect." The vehicle is also equipped with three overpressure collective, automatic and artificial fire extinguishing system, hot smoke system and three-color camouflage camouflage paint and other special protective equipment.
The US turret and the 25-mm machine gun became a new weapon system, the turret for the square wedge single turret, 25 mm machine guns placed in the right side of the turret, parallel machine gun mounted on the left side of the turret. The left side of the turret is the long position of the cannon, the window is equipped with a front open gun window. The window is surrounded by four periscopes. The front of the turret is equipped with a cannon light day / night with a sight. Turret inside the left side of the turret fixture, turret seat with self-sliding plastic ball.
The basket assembly is integrated with the turret body and rotates with the turret. The tail of the turret is fitted with a cartridge shell. The turret is electrically driven and equipped with an automatic firing device. When the drive window and the carrier window are open, the turret is automatically lifted when the turret is rotated close to the area. After passing, the barrel will return to its original height Continue to turn. The turret is a composite armor structure that improves the protective performance and the rigidity of the turret. To improve the overall vehicle center of mass position, the designer moved the original vehicle turret seat center line to the left by 10 mm.
Turret on the M242 25 mm machine guns, high flat dual-use, to Ping-based, can be fired armor-piercing, killing grenades and other ammunition, for the bombs for the chain, one-way two-way automatic for the bombs, two bomb chain Sub-left and right at the same time take the machine cannon, all the way to play chain can wear armor, another way can be loaded grenades, but also two loaded the same bomb species. The gun can be single, short burst (with 3 bursts and 5 bursts of two) and long bursts, the maximum firing rate of 200 rounds / min. The auxiliary weapon of the vehicle is a M240 7.62 mm parallel machine gun (with the machine gun installed in the same trunnion, also known as coaxial machine gun), 3,000 rounds of the bullet. NFV-1 vehicle is the biggest feature of the turret, and the highlight of the turret is the machine guns.
First, high speed and power to deal with light armor targets and infantry powerful weapon system. Type 86 of 73 mm artillery effective range is only about seven or eight kilometers, and the initial speed is very low, hit accuracy is not ideal. The vehicle installed 25 mm machine gun, launch armor piercing, the initial speed of up to 1325 m / s. This is not only the beginning of the 73 mm artillery catch up, and 59 tanks than the original use of armor-piercing, the effective range has reached more than 1,500 meters, to effectively compete with foreign equipment are now equipped with various types of infantry fighting vehicles.
The tungsten core armor piercing shells power can not be underestimated. At a distance of 1500 meters it can effectively break down of foreign equipment such as various types of light armored combat vehicles.
Second, the fire control system is more advanced. The gun fire control and sighting device for the two-way stability, with tracking and locking target fast, hit high precision, easy to operate, can be continuous between the shooting, night fighting ability and other significant features. In addition, the tanker can use the stabilizer to automatically control the gun, but also manual guns. Gunner sight for M36E3 day / night daylight / light sight. In order to facilitate the gunner observing the battlefield, the turret there are four M27 type periscope.
The Type 86 had no fire control system - gunner through the sight of the manual training aimed and shooting, poor precision, low hit rate, night vision is active infrared The distance from the near, the light source exposed. NFV-1 vehicle had a two-way stability of the fire control system, can be shot between the road, night shooting with low-light night vision device has a long distance, good concealment and so on.
The vehicle used 25 mm chain machine guns, arranged in the turret right side, two-way single-way for the bomb, can be a single, short burst, long bursts, equipped with a grenade and shelling armor piercing shells. On the left side of the turret there is a 7.62 mm parallel machine gun. Turret direction rotation and artillery high and low pitch for the electric drive, but also manual, the turret can be rotated 360 degrees, artillery pitch range of -7 degrees to +47 degrees, gunner sight for the M36 day and night a sight, can be installed two-way stabilizer; Fighting full weight to 13.6 tons.
The prototype was officially exhibited at the Beijing International Defense Exhibition in 1986, followed by driving and live-fire shooting at the Beijing test site. In September 1987, at the invitation of Egypt, it participated in the International Defense Exhibition held in Egypt in November 1987, and conducted a comprehensive vehicle performance and shooting test.
