After the successful launch of the new Russian tank T-90ms, the Internet, some are interested in the topic questions have been raised regarding the availability of reactive armor blocks on the side of the tower and projection devices feed box for extra ammunition. I suggest you familiarize yourself with the schemes of the official prospectus (the developer KompyuterLend elviassa@list.ru) and our pictures.
1. Dynamic protection.

As clearly shown in the diagram and photos, container dynamic protection there, hidden from prying eyes screen thickness not less than 5.4 mm (for the eyes). The units are designed similar to the DZ protivotandemnoy protect combat vehicles light class, the development of scientific research institute of Steel. The attack in the turret RPG or missile systems, early work lattice screens (armor steel 4-5mm), followed by metal mesh screen in the form of a basket of things for the crew and ammunition.
2. Box for extra ammunition.

"In developing the OMB considered a very important aspect to significantly improve the survivability of the crew, and the HPA tank as a whole. According to studies, the distribution of lesions projectiles in azimuth ± 35 ° has a substantially linear relationship as a result of the vertical plane tends to result in an increase in the tower. According to the research fewest hits PTAs have the lower part of the hull.
For this reason, the placement of automated CD in the rear compartment of the tower, communicating with the fighting compartment for loading the gun-type, realized Omsk design bureau under the ROC "Burlak" dramatically increase the deadweight losses of tanks and crews, tank actually leads to a very low survivability. The fighting in Iraq 2003goda clearly demonstrated fact almost 100% of irretrievable losses of tanks M1 "Abrams" in the defeat boeukladki, located in the turret and separated from the crew closing bronezaslonkoy. In this case, the upper panel with knock practiced regularly, BC detonation was observed. Thus, for better survivability ammunition (BC) tank gun should be located on the bottom of the tank — at least infestation of affected area.
To this end, BC gun on the modernized tank type T-90 is divided into three groups of pilings. The two groups are placed inside the tank at least the targeted areas: BC mechanized conveyor placed in the automatic loader AZ185M2 in the bottom of the case (22 pieces), non-motorized — in the septum MTO (8 pieces). The third group of ammo (10 rounds) is moved to an isolated bay from the crew compartment — an armored box, located at the stern of the tower. This is used to replenish ammunition transporter A3 and non-mechanized boeukladok at bus stops outside of combat.
Here it should be noted that the original promise of the Ural tank designers, the idea was to completely abandon the CD in non-mechanized stacking, leaving him alone in the carousel AZ. On the one hand, such a proposal to reduce the transportable BC shocking, but on the other hand, it is necessary to take into account that the increased power of arms and particularly the possibility of MSA on virtually guaranteed defeat the purpose of the first shot, it can do so without loss of combat effectiveness. Combat experience and special studies show that the T-72B in BC shooting 45 rounds with the TOUR, affects 14-17 goals, and upgraded T-90 is capable of 22 shots guaranteed to hit 20-21 bronetsel, and for significantly less time. At the same time, the Russian Defense Ministry insists that the Ammunition BC T-72/T-90 type tanks shall not be less than 40 shots. It is for this reason that it took to enter the third extra styling in an armored box for the tower. " "T-90M-breakthrough into a new quality" magazine "Arsenal» № 5 (29) 2011.
Additionally, you can say that the most dangerous part of the ammunition — part-combustible cartridge case with a charge placed in the middle compartment boxes, covered so even offices with less flammable projectiles. Interesting in its design department — the charges are arranged vertically in steel pencil cases, pencil cases with a gap inserted in the tray, which is in turn inserted into an armored box. Thus, we achieve separation barrier. The space gaps, in a combat situation can be filled with liquid, gel or bulk inert or fire extinguishing compositions. Cover mounting box is designed so that in the event of excess pressure of certain parameters, it is cut and cover works as a knock-out panel. It should also be added that in the same box an armored tank Ukrainian BM "Hold-M" with comparable dimensions is only 5 shots, the remaining space is filled with blocks of electronic equipment, which the Ukrainian designer could not zakomponovat the scope of the old tower. The design of an armored box on the BM "Hold-M" is much simpler and constructively provides secure storage of ammunition, the defense side of the projections of the tower and additional ammunition is not provided by the tandem of ammunition.
