Design
editProject 971 has a double-hull design. The robust body is made of high quality alloy steel with σт = 1 GPa (10,000 kgf / cm2). To simplify the installation of equipment, the boat was designed using zonal blocks, which made it possible to transfer a significant amount of work from the cramped conditions of the sub's compartments directly to the workshop. After completion of the installation, the zonal unit is “rolled” into the hull of the boat and connected to the main cables and pipelines of the ship's systems.[6] A two-stage damping system is used: all mechanisms are placed on damped foundations, in addition, each zone unit is isolated from the body by rubber-cord pneumatic shock absorbers.[6] In addition to reducing the overall noise level of nuclear submarines, such a scheme can reduce the impact of underwater explosions on equipment and crew.[7][6] The boat has a developed vertical tail unit with a streamlined boule, in which the towed antenna is located. Also on the submarine are two reclining thrusters and retractable bow horizontal rudders with flaps. A feature of the project is the smoothly mated connection of the tail unit to the hull. This is done to reduce noise-generating hydrodynamic eddies.
Power supply is carried out by a nuclear power plant. The lead boat, K-284 Akula, is equipped with an OK-650M.01 pressurized water-cooled nuclear reactor. On later orders, the AEU has minor improvements. Some sources report that subsequent boats are equipped with OK-9VM reactors.[8] The thermal power of the reactor is 190 MW, the shaft power is 50,000 liters. with. Two auxiliary electric motors in the hinged outboard columns have a capacity of 410 hp. with., there is one diesel generator ASDG-1000.
Construction and career
editThe submarine was laid down on 10 September 1989 at Sevmash, Severodvinsk. Launched on 26 June 1993 and commissioned on 29 December 1993.[9] On 27 July 1991, she was renamed Tigr.
In 1995, he completed the tasks of combat service with the crew of the plak Wolf under the command of the Cap. 2nd Rank Alexey Vitalyevich Burilichev.[10]
From 1998 to 2002, at FSUE PO Sevmashpredpriyatie an emergency and recovery repair of a steam turbine unit was carried out. The crew is temporarily subordinated to the 339th obrempl Be naval base.[10]
On 1 June 2002, she returned to the 24th submarine 12th pilot of the Northern Fleet with the previous base.[10]
In 2003, she completed the tasks of combat service.
In 2006, she completed the tasks of combat service.
As of 14 August 2020, the boat is being repaired and modernized for the Kalibr missile system at the Nerpa plant until 2023.
On 11 January 2021, according to TASS, citing sources in the military–industrial complex, repair work and restoration of the technical readiness of the Tigr nuclear submarine is planned to be completed in 2022.[10]
