Tank T-90SK/T-90MS factory and field acceptance tests.
One tank from a batch of 25 tank is checked for leaks. The tank is being immersed in a special pool 5 meters deep located in shop#130 at UralVagonZavod (UVZ). Duration of the hydraulic test is 20 minutes.
Typical numbers for the water leak rates are 0-0,05 lpm. If the water leak rate exceeds 1 liter per minute, the test is failed.
Fire control system, climate (A/C) system, sighting systems are also being tested.
Powertrain testing: the engine, transmission (consisting of primary reduction gear, two planetary final gearboxes and two planetary final drives), and the final drive (continuous track)
Suspension testing: on each side of T-90 there are six dual rubber-tyred road wheels with the drive sprocket at the rear, idler at the front and three track-return rollers. Hydraulic shock-absorbers are provided at the first, second and sixth road wheel stations.
125mm 2A46M-5 smoothbore gun fires conventional natures of separate loading ammunition (projectile and charge) including HE-FRAG (high-explosive fragmentation) and APFSDS-T (Armour Piercing Fin Stabilised Discarding Sabot - Tracer). It can also fire a 9M119M laser guided anti-tank projectile fitted with a tandem HEAT (High Explosive Anti-Tank) warhead out to a maximum range of 5,000 m. The T-90A uses an automatic loading system with 22 rounds ready to fire that provides high rate of fire (up to 7 rounds per minute). A 7.62 mm 6P7K machine gun is mounted coaxial with the main armament and a remote weapon station UDP T05BV-1 is mounted on the turret roof armed with one 12.7 mm NSVT heavy machine gun. This remote weapon station can be laid and fired from within the turret.
A bank of six electrically operated 81 mm smoke grenade launchers mounted either side of the turret is the aerosol generating system that uses 3D17 grenades of 902A Tucha (Cloud)
The duration of tests at the testing ground is 6 hours.
