Tank Gun 2A46M- 5 & 4 - 2A46M
Tank guns 2A46M-5 and 4-2A46M
Yesterday, 9:22
In 2006, "Uralvagonzavod" for the first time revealed the new T-72B2, which differed from the previous machines family a number of innovations. One of the main features of the new machine was the upgraded gun 2A46M-5. It is a tool with the ability to launch missiles represents a further development of arms family 2A46 and differs from the older guns around design features and their associated characteristics. According to official information Yekaterinburg "Factory №9», created an instrument 2A46M-5, the use of new technical solutions allowing significantly improve its performance and to ensure superiority over other weapons family.
It should be noted that the designers' Plant №9 »parallel developed two new versions of tools 2A46M: 2A46M-5 and 2A46M-4. These guns have a few differences due to their destination. Cannon 2A46M-5 should be established by the family with upgraded tanks T-72 and T-90, and 2A46M-4 was designed to equip the machine T-80. The most noticeable difference between these guns - different design of the left fence. Guard gun 2A46M-5 have been designed using "Tagil" autoloader and fencing 2A46M-4 compatible with the mechanism of loading T-80 tank. All other components and assemblies guns unified. Due to the minimal differences we will consider the example of the two guns 2A46M-5.
New tank guns of both models are an upgraded version of the previous guns family developed using a number of new ideas. The main methods of achieving higher performance steel cantilever stiffening of the barrel, improving dynamic balance gun tighter manufacturing tolerances of the barrel and the barrel mounting system update in the cradle.
Cannon 2A46M-5 can be mounted on the same mounting system as the 2A46M. 2A46M-4, in turn, on the installation place is interchangeable with 2A46M-1. The most noticeable external difference is the updated tools device incorporating bends the trunk. The device is installed above the breech and muzzle fastened around the reflector. Device incorporating bends determines the deviation of the axis of the barrel from the neutral position, and sends the data to the fire control system. Using the data in the calculation of the bending of the trunk to improve the accuracy during intensive firing and compensate for the deformation of the pipe barrel, caused by heating.
When upgrading large changes were cradle guns. Thus, to reduce the cantilever barrel is proposed to use a cradle with a neck long by 160 mm. The modified filler has higher rigidity in comparison with the items of previous tools of the family. Furthermore, the design of the cradle used in the second prism of the bronze sleeve.
The project 2A46M-5 / 2A46M-4 reduced tolerances on geometry of the barrel. Nevertheless, in the production of tools may form during installation clearance barrel into the cradle. For a tight fit in the barrel cradle is equipped with two lyuftovybirayuschimi last devices in the front and rear portions of the upper surface. The composition of each of these devices includes two bushings with rollers placed in special mine in the cradle and pressed screw caps. Four rollers firmly pressed against the trunk to the lower inner surface of the cage and allowed to get rid of the backlash.
Redesigned bearing sliding parts of the gun. Front support comprises two annular bronze bushings back consists of four rectangular claddings of the same material. Rear suspension transferred to oboymennuyu of cradle. These improvements have improved fixation barrel on legs, as well as eliminate the tipping point during the rollback.
Cradle guns 2A46M-5 is equipped with new devices for installation in the tank. In particular, applied new tsapfennye backlash-free bearings with hollow rollers with an elastic surface. These bearings reduce clearances when installing the gun, as well as improve the fixation pins in the tower of armored vehicles.
Like the previous arms family, the gun is equipped with a 5-2A46M smooth trunk caliber 125 mm length of 6 m. Length of the bolt - 840 mm. To improve the accuracy of shooting guns got upgraded barrel, made with smaller tolerances. In the course of project development and production technologies able to optimize the geometry of the barrel while maintaining the required performance. Thus, the increased stiffness of the pipe trunk of 10% up to 420 kg / cm. In addition, reduced nonuniform muzzle of the barrel to a length of 1 m. Upon request, the bore can be chrome-plated, which increases its life.
For ease of maintenance gun barrel 2A46M-5 is attached to the breech using a bayonet connection. When dismantling the barrel requires to put on his octagonal part of special wrench, turn the barrel at 45 ° and squeeze it out of the breech. Using a crane up to 2 tons, repair department can replace the barrel for about 4 hours. Dismantling of the tower is not required, which is a characteristic feature of the family 2A46M guns.
During rollback gun barrel acts overturning moment. To reduce it in the design of the gun 2A46M-5 used recoil device with diagonal arrangement brakes rollback. One of them is in the top right (when viewed from the breech guns) of the breech, the second - in the lower left. Right from the lower brake provided recuperator. All hydraulic components are equipped with devices implements visual monitoring of fluids.
The projects 2A46M-5 / 2A46M-4 was to improve the characteristics of the fire. Main characteristics, such as the firing range or power of ammunition remained at the same level or depend on the type of projectile used. At the same time significantly increased accuracy specifications. In comparison with the instrument 2A46M grouping is increased by 17-20%. The total dissipation when firing on the move is reduced by 1.7 times.
Guns 2A46M-5 and 2A46M-4 can use the full range of 125-mm ammunition for the guns 2A46 family. Furthermore, they can be used as a launcher for missiles complexes "Cobra" and "Reflex". Improving the characteristics of guns increases the efficiency of the fire, even when using existing ammunition.
Cannon 2A46M-5 and 2A46M-4 are intended for installation on tanks families of the T-72, T-90 and T-80. Possible to mount the gun not only for new combat vehicles, but also on existing technology during its renovation and modernization. According to some data, in 2006-2007, upgrade your weapons 2A46M-5 / 2A46M-4 was taken on the Russian army and was installed on new tanks.

Kemungkinan karena menanggapi serius kicauan orang-oang pinter di bidang teknologi persenjataan tank di formil ini, dimana org-org tersebut selalu memberi informasi bahwa tank-tank Russia itu tergolong tank "kaleng krupuk" dan tidak mempunyai daya gempur heibat seperti tank Leo, Chieftain, atau Abrams dan Merkava, maka Russia meningkatkan dengan sungguh2 R&D bagi keperluan daya gempur tanknya T-72 dengan meriam lebih maju technologinya.
Tentu ini akan memerlukan Sertipikat "Betel Prupen" dan akan memberi masukan yg berharga kepada kelompok ahli senjata tank di formil ini, ba hwa senjata yg terpasang di tank Russia T-72 sekarang ini juga sudah lebih maju berkat " ejekan dan olok-olok" mereka.
Padahal, para "ahli" itu juga g pernah berbuat apa-apa, cuma pinter "ngomong" doang.
