The PTS-3 ( Russian ПТС-3, Плавающий транспортёр средний -3 in German: medium floating transporter 3 ) is a chain-driven amphibious landing vehicle from Soviet production. It is the third version of the PTS series , the first variant of which dates from the 1960s.
Development history
After almost 15 years of experience of the armed forces of the Warsaw Pact with the PTS-2 , various optimization possibilities were identified. This primarily concerned the driving characteristics and the speed in the water as well as the carrying capacity of the amphibious vehicle. The development work on the PTS-3 was carried out in the Luhansk locomotive factory by LI Posdijakowa. The first vehicles were introduced in 1988, but in the wake of the collapse of the Soviet Union and the associated financial bottlenecks, the PTS-3 was not introduced and production numbers remained low. Improvements implemented in the PTS-3 can be found in the most modern version, the PTS-4 .
technology
The load capacity of the PTS-3 has been increased so that loads of up to 16 tons can now be transported. Furthermore, the maximum speed in the water could be increased to 15 km / h. This was achieved by a different arrangement of the two drive propellers. In the PTS-2, the screws were located below the access ramp in a tunnel-like steel body; in the PTS-3, the drive was carried out using two ducted propellers (750 mm diameter), which were mounted on the underside of the ramp. It is controlled by means of two rudders per ducted propeller. Like the PTS-2, the chassis of the PTS-3 is based on the T-64 chassis, but it has an additional roller on each side. The engine is also composed of a water-cooled twelve-cylinder - V-engine of the type W-46-5 . The drive unit has a displacement of 38.88 liters and has an output of 710 hp (522 kW). The driver's cab, which is heated in winter, is lightly armored (protection against 7.62 mm projectiles) and, like the PTS-2, has a door to the loading area. To protect the crew, the tracked vehicle has an NBC protection and ventilation system, which is intended to ensure perseverance in areas contaminated with NBC weapons. The loading area has been increased slightly to 24 m² (8.285 m × 2.890 m) compared to the 23.6 m² (8.23 m × 2.87 m) on the PTS-2 . The PTS-3 can thus transport up to 75 people or a vehicle the size of a heavy military truck (e.g. Ural-4320 ). The PTS-3 floats without preparation, only the surge board at the bow has to be folded down to cross a water hazard.
MOP Derschatel
The pioneering version MOP Derschatel ( Russian МОП "Держатель" ) was built in 1992 in small numbers by the Luhansk locomotive works. The vehicle was equipped with a backhoe, the turntable of which was installed in the middle behind the modified driver's cab . The excavator arm is placed backwards and has a swivel range of 360 °. In addition, a smoke thrower was installed.
