The 2A26M2 weighed 2,350 kg without the stabilizer components attached beneath its gun cradle. In this position, the commander still has front body protection from the hatch. The AAU was founded on January 21, 1888, with the goal of creating common standards in amateur sport.
The passive image intensifier mode allows the same type of target to be spotted at ranges of up to 500 m if the ambient light is no less than 0.005 lux, which is the typical brightness of a moonless, starlit night with clear skies. The penetrator is made entirely of 60KhNM tool steel with high strength and toughness. In the semi-automatic mode, the rate of rotation is increased to 20 degrees, Minimum Gun Elevating Speed: 0.05° per second, 2E42-2 "Zhasmin" Hydroelectric Stabilizer, Maximum Precise Turret Traverse Speed: 3° per second, Maximum Precise Turret Traverse Speed: 6° per second. Additionally, the supercharger of the ventilation unit can be used while bypassing the filtration system in an auxiliary mode by turning it on manually.
The main improvement of the T-72 driver's station over other tanks with the same seating layout is the increased legroom.
The TPD-K1 sight is retained as a backup to the Sosna-U. The diagram is from a T-72A manual. Alternatively, each barrel can be used to fire a maximum of 250 standard APFSDS rounds (3BM9) or 200 rounds of newer types (3BM15, 3BM22). A major advantage of the heater design is that the boiler does not need to be running to provide heat for the crew, as heat is supplied by the engine with the added bonus of marginally contributing to the cooling of the engine.
'The Spectator', volume 1 of 3 (plus translations and index), comprising previously unpublished eighteenth-century essays, poetry, letters and opinions, originally edited by Addison and Steele, now available in html form, as a free download from Project Gutenberg In reality, autoloader failures are exceedingly rare (but not non-existent), so there is little need to worry about manual loading. Even so, the additional width provided by the design of the T-72 autoloader is still a benefit. It is entirely impossible to communicate with R-130M radios, as those work in a narrow frequency band of 1.5-10.99 MHz. The single advantage of the narrow chamber of the L11 was that in combination with a vertically sliding breech block, the entire breech housing could become quite narrow - only 485mm, equivalent to the 122mm D-25T gun (480mm) and 115mm U-5TS gun (495mm). in the end, which APFSDS can the older T-72B3 use? Being a modernization of the TPD-2-49 sighting complex, the 78% of the components of the TPD-K1 were unified with its predecessor.
This is the signal for the driver to immediately reverse the tank back into cover. The altitude of the tank above sea level is determined by the tank commander by referring to his map. One on the right hand side (the left side in the photo) for smaller things, and the central compartment, which is large enough to contain practically anything.
The addition of the flatscreen display and the digital ballistic computer eliminates the possibility of stowing ammunition in the turret on the wall behind the gunner, as the gunner's master control panel is now moved to a spot behind his left shoulder, and the ballistic computer housing occupies quite a lot of space behind his seat. This feature is also integrated to the 1A40, 1A40-1 and 1A40-1M sighting complexes. A hard knock on a stiff plastic pad would not be comfortable, it would certainly be preferable to a knock on bare steel. The seat itself is the same as an ordinary T-72B driver's seat, only that it is mounted to a special frame attached to the suspenders.
Here in the west we always tend to subestimate the russian equipment and in the wrong situation it can get you killed.By the way a Leopard-2 or a Abrams also stores ammunition in the chasis, if this ammunition gets hit it easily can kill the entire tripulation and even blow off the turret as well, but I agree that this is easier to happen in a T-72 compared to a tank that has stored the ammo in the same place instead of all over the compartment. Found inside – Page 360He will twist his body into ten thousand uncommon stature , and with strength proportioned feet , and some even exceeded nine feet in height ; shapes , and then open wide his mouth , and jump to their gigantic size . TKN-3 has no image intensifier (only active IR illumination), TKN-3M has the 1st Gen image intensifier and TKN-3MK has a 2nd Gen image intensifier. It also served to break the eroded copper driving band once the projectile assembly leaves the muzzle, acting in conjunction with the force from the airflow acting on the scoop-shaped sabot petals to ensure consistent separation from the projectile. It is also blocked if the commander's seat adjustment mechanism is positioned directly over the gap. It was launched into service in the 2000's, but has been slow to proliferate. Thank you. A short spade is clipped onto the hatch, and some equipment is usually placed on top of the hatch for a lack of better storage space inside the tank. At the time the R-173 was introduced, the radios used in NATO tanks were still of the previous generation - or in other words, analogue devices with no built-in encryption. This made it infeasible for enemy forces to utilize indiscriminate or barrage jamming - which was previously possible against the R-113 due to its narrow 20.00-22.375 MHz frequency range - as the range of possible frequencies was too large, and even if it were attempted, indiscriminate jamming would impair their own radio communications. For the T-72, these markings are not to be used as the primary method of rangefinding as the gunner has access to a much more precise optical or laser rangefinder, depending on the T-72 variant.
It erodes at a rate of 0.0165mm. ⭐ A community of mentors, small class sizes, and faculty that truly care and are ready to welcome you to Mayo Clinic!
All T-72B tanks are fitted with a set of both an R-173 and R-173P as part of the radio station.
Found inside – Page 55... two complete suits of armour , one turity look to what concerns them -- we are men of of mail , the other of plate , both of which , from their this age , and to this age we will confine our case . great size , seemed to call the ... The R-173 can be used to to transmit and receive voice signals for normal communications, or transmit and receive encrypted analogue and digital data.
It is located around the focusing cone of the shaped charge warhead. Naturally, the high operating pressure of the gun was achieved with a large amount of highly energetic propellant. On another note, it is interesting to observe that although the turret of the T-72 lacks handrails for tank riders like preceding Soviet tanks, the practice of hitching a ride was still occasionally taught and exercised.
Kevin Plank, a former University of Maryland football player, established Under Armour in 1996 with the mindset to elevate the athletic experience for both men and women with innovative performance apparel, footwear and accessories. With an operating frequency range of 30-107.975 MHz and a frequency step of 25 kHz, the R-168-25UE-2 has a much wider operating band than previous radio sets, but because the minimum frequency is 30 MHz, full interoperability is only possible with the R-173 series and not the R-123 series, which has a minimum frequency of 20 MHz. The parallelogram-type mechanical linkages that connect the sight (left side) to the cannon (right side) can be seen in the photo below. breaking which explains the low protection effect. From a technical standpoint, it shouldn't have been difficult to achieve with modern technology, but the Soviet electronics industry wasn't really all that "modern". More information on BR-354P is available in Tankograd's PT-76 article.
All of these tanks have the driver's periscopes installed in his hatch or on the hull roof behind the hatch which allows the driver to operate his controls with a more natural posture. The tungsten alloy armour piercing cap has a larger diameter than the core and protrudes beyond the steel body, so that the armour piercing cap invariably strikes the target before the rest of the projectile even on a very high obliquity target. The high cost effectiveness of the T-72 undoubtedly had a large influence on the monumental export success of the tank, especially considering that the core customer base for Soviet and Russian arms are Second World or Third World nations that typically do not have a large procurement budget and want the maximum return on their investment. Category 2 is reached when 250 shots with 1 EFC are fired or erosion reaches 0.9mm (25%).
When seated normally, the positioning of the driver's lower body is comfortable. The cover is additionally covered in up to two layers of "Podboi" anti-radiation lining with a thickness of around 13mm each. There are two 4.2mm holes per petal, angled 50 degrees tangentially along the projectile axis. Classes start July 2021. This capability was not present in NATO tanks at the time. I have checked everything so far but have not seen anything wrong yet.
However, some other sources state that the muzzle velocity is 1,715 m/s. The mechanism for this system is shown in the drawings below. 09/02/2021. The 2A46M featured a new breech block, gun cradle, recoil system and a new barrel with an interrupted screw mounting jacket which permitted quick swapping in field conditions. This comment has been removed by the author. Get the best deals on Boys' Clothing (Sizes 4 & Up) ... NWT Boys Youth Under Armour Athletic Jogger Pants Pitch Gray UAFEC13E Size 6. The periscope only has a horizontal field of view of 36 degrees and a vertical field of view of 33 degrees. The R&D project "Vant" entered service in 1985 as the 3VBM13 round with the 3BM32 projectile. The trigger buttons transmit electrical pulses to a solenoid mechanism affixed to the rear of the machine gun receiver, operating the sear and thus firing the weapon.
It would take a maximum of 20 seconds for the turret to complete a full 360-degree, revolution. The dimensions of the R-173 transceiver unit are 428x240x222mm. According to a study on the feasibility of an APFSDS penetrator augmented by a small shaped charge, a live firing test showed that 3BM42 achieves conditional defeat (partial penetration) on a 350mm medium hardness armour steel plate when fired at a muzzle velocity of 1,350 m/s. When driving in rain or snow, the hood of the dome covers the driver. The proper method of aiming with the sight is for the operator to keep both eyes open and look through the sight with his his right eye, allowing his brain to perceive the projected sight reticle in his vision through both eyes. The total weight of the in-flight projectile is 4.7 kg, including the stabilizer fins (0.435 kg), the tracer (0.03 kg), the penetrator and aluminium ballistic cap. For example, the two 12-volt batteries in the Challenger 1 turret have a total charge capacity of 100 Ah and allow the tank to operate in a silent watch mode for a nominal duration of 8 hours. The jacket can clearly differentiated from the tungsten rod in the photo below, taken from Andrei Tarasenko's website, btvt.narod. Despite being tubular sticks, which are geometrically inclined to produce a neutral burn rate, progressive combustion of propellant was achieved by introducing phlegmatizers into the outer layers of the finished propellant tubes.
The commander has to :). The barrel life of the 2A46M is greatly inferior to that of the M256 and Rh120, as the former has a useful life of 600 M829A1 rounds and the latter has a useful life of 700 DM13 rounds, or. The driver activates an air jet by twisting a valve on the air distributor unit.
It had a nominal range of between 16 km to 50 km depending on the terrain, weather conditions and noise levels, but according to the manual, with the whip antenna fully deployed to its 4-meter length, a T-72 travelling at 40 km/h with the radio noise suppressor turned on can expect a broadcast and reception range of at least 13 km or at least 20 km without the noise suppressor. Only the Leopard 1 provided the crew with both a personnel heater and a hot plate from the very first production models, making it arguably one of the most habitable tank of its peers even though, much like the T-72, it was not the most spacious. The alternative is to have three smaller periscopes, one to see forwards and two to see each corner.
he first layer is a NERA panel made from a sandwich of 7mm Armox plates with a 3mm center layer of rubber. The impact velocity is not known, but must be less than 1,350 m/s.
Information shared by the online user "Fu_Manchu" states that the spread of L15 APDS rounds at 3,000 meters is 1.925 m in the vertical plane and 1.375 m in the horizontal plane.
The commander would obviously load the cannon using ammunition close to him, and vice versa. Wood fibers are almost entirely composed of cellulose, which combusts to leave carbon products. Please confirm at checkout. When the decision to modernize 125mm tank guns was made in the late 1970's, a number of new technologies such as autofretting had to be implemented to accommodate the greatly increased ballistics of new ammunition. This solution provided.
T-72 tanks are equipped with the ZU-72 anti-aircraft installation with an NSVT heavy machine gun. The precursor is 42mm in diameter. Of that, only 800mm of its length can be occupied by a two-part cartridge. This creates a strong draft to help keep the crew cool, while at the same time, improving the purity of the air for the engine in dusty environments. Replacing the rest of the autoloader requires the turret to be partially dismantled. However, in practice, crews tend to ignore certain spaces such as the shell stowage rack on top of the carousel cover (as seen above), and some crews may decide not to have any ammunition in loose stowage at all, so the actual sum total of loosely stowed ammunition can be anywhere from 22 to none. The upgraded memory storage unit was also improved for better reliability. The Chieftain allowed both the gunner and commander to swap out their day sights for an IR night vision sight, but according to historian and former Chieftain crewman Rob Griffin, this required a relatively lengthy boresighting and recalibration process, which would have to be repeated when swapping back the night sights for day sights.
