The main idea of the author is to develop an alternative layout of a tank support combat vehicle (hereinafter - BMPT) with a higher level of crew protection than existing BMPTs. Spaced armor, non-standard internal layout of the vehicle, altered arrangement of internal equipment and duplication of some components of the vehicle provide additional protection for the crew when the main armor is penetrated.
Two openly spaced 57-mm cannons make the car look like the "inflated" from 2x30 mm to 2x57 mm "Terminator" the center of a fairly large tower.
The proposed alternative BMPT-100 (pictures and text) is a sketch of the author's work, which does not claim any exact technical and tactical correspondence.
Fig. 1. General view of BMPT-100
Fig. 2. BMPT-100 front and top view
The vehicle is part of a family of combat vehicles based on the alternative T-100-140 tank, and therefore, it provides for the use of the chassis of this tank without any special changes.
Fig. 3. BMPT-100 chassis
The main feature of the alternative BMPT-100 is the increased protection of the crew of 3 people, as a result, the large mass of the vehicle - 62 tons (equal to the mass of the T-100-140 tank).
Rice. 4. The layout of the BMPT-100 hull
The main armament of the BMPT consists of a complex of weapons of the well-known ZSU-57-2 - two paired 57 mm S-60 automatic cannons.
Such a complex of weapons for BMPT will certainly be controversial, tk. this is not a ZSU and a 2nd gun, its booking and auxiliary mechanisms will only make the vehicle heavier, however, the presence of 2 guns was a consequence of some non-standard layout and technical solutions:
1) The new layout of the crew in the tower "in a helicopter".
Fig. 5. The layout of the BMPT-100 tower
With this arrangement of the crew (the commander sits behind the gunner along the longitudinal axis of the turret), increased protection of the crew from the sides is provided - the size of the armor plates and the ammunition, mechanisms and assemblies located between them is: ДЗ + 1200 mm + lining. The crew is in a kind of "armored capsule", which in the front projection is protected by combined spaced armor with the "Duplet" dynamic protection system. The size of the armor in the area of the frontal projection of the armored capsule is: DZ + 800 mm + lining (in the version with additional protection: screen + 600 mm + DZ + 800 mm + lining). The two upper hatches are also located along the longitudinal axis of the tower, one after the other. The use of only one 57-mm cannon along the axis of the turret would limit the possibility of evacuating the crew, since embarkation / disembarkation would be possible only with the gun raised up, in other positions the crew would be trapped by the cannon barrel inside the vehicle. In the proposed BMPT model, the crew can leave the car at any angle of inclination of the barrels. the distance between them allows the crew to freely crawl between the trunks.
2) The design of an automatic ammunition rack, consisting of 4 independent chain conveyors (2 pairs on each side, the capacity of each conveyor is 42 shots). With this design, a large capacity of automatic ammunition storage is provided - 168 rounds. Replenishment of transporters is possible from the fighting compartment without stopping the operation of the cannon (even at the moment of firing). The BMPT commander is replenishing the ammunition load, to the right and left of him on the rotating floor of the fighting compartment there are two manual ammunition stows, each with a capacity of 42 rounds (full transportable ammunition - 252 rounds). At the moment when the cannons are powered by the two upper conveyors, the commander can replenish the two lower conveyors through special hatches in the armored partitions, and vice versa, when the cannons are powered from the lower conveyors, the upper ones are replenished. The theoretical time to replenish any two transporters (84 shots) is 6-7 minutes. Normal firing mode - simultaneous salvo from 2 guns
In the event of failure or defeat of one of the guns or automatic loader, it is possible to fire from one gun.
3) An additional advantage of the two-gun mount is the higher rate of fire of the cannons - up to 200 rds / min, which provides additional capabilities in the fight against air targets. With a regular double shot (for higher firing accuracy due to simultaneous recoil), projectile overruns are likely. This disadvantage is partially offset by the large ammunition load and the low cost of standard 57-mm rounds as a consumable.

Rice. 7. BMPT-100 armament complex
As a guided weapon (for maximum unification with the T-100-140 tank), it is proposed to use universal launchers that fire with "tank" TUR "Kombat" of various modifications. Structurally, each launcher for TUR has two channels with a diameter of 140 mm with a closed rear part, similar to the breech principle of a tank gun (since the missiles are the same). The launcher is loaded from the rear, when the installation is raised in the 0 degrees position and the side anti-cumulative grille is folded back by 90 degrees.
TUR are assembled from 2 parts in the launcher channel. Transportable ammunition consists of 6 missiles: 4 - in the launcher and 2 - in the BO in a special ammunition rack. Both "short" TUR "Kombat" 140 x 1065 mm and "long" TUR 140 x 1500 mm can be used.
The proposed range of missiles used is 5 types.
If necessary, launchers with TUR can be changed to launchers with AR-8 (S-8) aircraft missiles. For accurate firing at heavily fortified objects (pillboxes, bunkers, and others), it is envisaged to use AR-8L corrected aircraft missiles.

Fig. 8. Additional protection of the BMPT turret
Machine rating:
Advantages:
- New turret layout, provides increased protection for the crew from the sides and stern;
- The layout of the T-100 chassis provides additional protection for the entire crew during armor penetration;
- The driver can urgently leave the BMPT in any position of the tower;
- The high rate of fire of the guns (at the level of the ZSU-57-2) increases the firepower of the BMPT, including when fighting helicopter gunships;
- Caliber 57 mm allows you to use a wide range of shots, including HE shells with remote detonation and anti-aircraft guided shells with seeker;
- Possible replenishment of the automatic loader simultaneously with firing from the cannon;
- Universal launcher, which can use various 140 mm ATGMs used on the T-100-140 tank;
- The modernized MSA allows you to aim at the targets corrected NAR AR-8L.
Disadvantages:
- Large weight (62 tons) and height (3400 mm);
- The cost of the vehicle is comparable to the cost of a promising tank;
- Only one simultaneously hitting target;
- Accurate aiming fire is possible only when firing from 2 guns at the same time;
- Large frontal projection of the BMPT (because of the cannon pedestals);
- High line of fire 57 mm guns;
- Sophisticated automatic loader;
- Excessive consumption of shells due to a "double" shot (compensated by a large ammunition load);
- Side exhaust increases the visibility of the car;
Possible prospects for further modernization:
- Installation of a promising 6TD-5 engine with a capacity of 1800 hp. (increase in specific power up to 29 hp / tn);
- Equipping the tower with a set of removable anti-cumulative grids, providing additional all-round protection of the tower from RPG shots;
- Further increase in the size of the combined turret armor due to new armor modules, tk. an increase in its size does not prevent the mechanic from leaving the BMPT through the rear ramp;
- Installation of a standard active protection complex (KAZ);
- Creation of an alternative ZSU on the basis of BMPT-100, firing guided 57-mm UAS projectiles and anti-aircraft missiles (presumably, the ZSU should be as similar as possible to the BMPT to misinform the enemy);
- Integration of the remote control system of the vehicle (for special operations in the hottest spots without threatening the life of the crew), thanks to electrical control systems, video surveillance channels and a fairly capacious automatic loader of 57 mm cannons (168 rounds).
- Installation of advanced power plants-power units (based on fuel cells) that generate electricity for traction motors and the on-board network due to the chemical reaction of the fuel;
- The use of electromagnetic or electrochemical guns.
