Capacity Russian submarine forces, which were intended for the destruction of surface ships and enemy ships in the 1960s., Was carried out not only by the creation of nuclear-powered submarines armed with anti-ship missiles (SSGN, project 675), and by the rocket diesel-electric submarines. Draft Project 651 diesel submarine, which has a silver-zinc battery and Missiles, developed on the basis of Council of Ministers Resolution № 1149-592 of 08.17.1956 and of 25.08.1956 № 1190-610, also tactical and technical specifications of the Navy, approved 28.01.1957. Submarines of Project 651 was to arm themselves with cruise missiles P-5, created for firing on the area and the self-guided antiship missiles P-6 (data missiles were developed in OKB-52). Conceptual design, developed on the job, approved in May 1958 on its base have developed those. project, which approved in January 1959
The project is developed in the Central KB Marine Engineering "Rubin" under the AS Kassatsiera, head designer and his deputies SE Lipelisa, FA Sharov, KZ Saravayskogo. The main observing from the Navy was assigned IA Kotsyubin, the captain of the second rank. Development of working drawings and tech. records began in the first quarter of 1959, and finished in the first quarter of 1960 to verify the placement Underwater Boat personnel and equipment was conducted full-scale prototyping. The plant number 196 breadboard compartments 1st to 3rd, at the factory number 194 — 4 and 5 compartments, at the Baltic Shipyard — sections from 6th to 8th. In the coming all the technical documentation of the project as directed by the 651 managers of SMEs was transferred to the CDB-112 SMEs.
Submarine Project 651, like all Russian submarines made since then has been performed with two-case and developed an add-fencing of strong cuttings. Strong body created from a cylinder diameter of 6.9 m and truncated cones in a 2-extremities. Strong body was divided into eight compartments by means of transverse bulkheads flat. All bulkheads were calculated pressure of 10 kgf / sq. see Bends were installed inside and outside the body strong. For loading / unloading of the main devices for the possibility of cutting a set of strong body and shell plates with the following welding a butt joint. Robust cutting a rounded shape, and the roof was in the form of radial cutting cylinder. The main ballast tanks is 14. Tank number 4 and number 11 were emergency ballast. They served to restore the buoyancy of the vessel in the event of loss of density of the 1st of 2-missile containers. Tanks number number 2, 3, 5, 7, 12 and 13 were the fuel and ballast. These tanks have been strong and Kingston. Other brain ballast tanks, except for number 1, which had a kingston and placed in the forward end of the boat, filled through the scuppers. All mezhdubortnom tanks have separate ventilation. The valves ventilation and Kingston had hydraulic remote.
Weight fired missiles replaced reception in strong water tank. Tanks were in the second compartment and in the vicinity of the feed containers mezhdubortnom space. The usual fuel in store housed inside a sound body and a 5-fuel tanks and a 6-and outboard tanks, two of them in the extremities, and others — in mezhdubortnom space. External design and sturdy buildings are calculated taking into account the requirements of anti-nuclear defense.
Enormous difficulties were caused by the development of fodder complex, whose main task was to provide a huge stroke speed at low noise level of the submarine. These difficulties were compounded by the fact that the submarine propulsion motors had a high power (6 thousand hp), which required the installation of propellers such size that the screws were not established in the adopted General dimensions submarine, and the increase in the latter was becoming a prerequisite for the loss of speed. In addition, the propulsion motors could hardly fit into the size of a sound body, restricting the camber roll band. After some constructive design study chosen option, in which the propellers were used to guide the nozzle and the aft end was devoted to building a form that allows you to reduce the length of the submarine. Propellers are designed as low-noise. Elected propulsion system allowed to reduce the amount applicable to the diameter of the screw and for all this critical increase travel speed (in other words, the rate at which significantly increases the noise of the vessel).
All hull design to ensure the highest dive to depths as the transverse bulkhead flat robust housing made of steel AK-25 and a yield strength of 60 kgf / mm. For the production of certain steel structures used of the AK-27 (yield strength of 52 kgf / mm). Strong external tank, the outer casing, sturdy fencing cutting and stabilizers first five submarines made of magnetic steel 45G17YUZ (yield strength of 40 kgf / mm). On the other submarines these constructions were made of steel SHL.
Shipbuilding factory during the development of magnetic steel 45G17YUZ met the technical difficulties associated with editing and cutting steel. This explains the inflated magnetic steel warpage caused by the physical qualities of steel — low thermal conductivity and coefficient of linear expansion inflated. In addition, 45G17YUZ cumbersome to fur. treatment. All this has become a prerequisite for the growth of the volume of work on the revision and match designs as well as it should, has led to a significant increase in residual stresses in structures.
The outer casing of serial submarines of Project 651 was covered protivogidrolokatsionnym coated with non-resonant horn channels NPPRK-4DZ. But in the first six vessels such coverag
e was missing since the time of the technology readiness of submarines have not yet mastered. Surface displacement submarine installation coverage increased to 3300 cubic meters.
The structure of power plants Project 651 submarines were:
— The two main diesel engine 1D43 (Kolomna factory), twelve-, four-, uni-directional, with a turbocharged, with integrated reduction gear, the power of each at 440 revolutions per minute 4 thousand hp and the diesel engine 1DL42 (Kolomna factory), six-cylinder, four-stroke turbocharged, power at 700 revolutions per minute 1720 hp, paired with a generator PG-142. Submarine-installed remote automatic control system designed to control diesel engines, airclutch, flapper venting and air supply to the engine, including the signaling of their operating parameters and status airclutch. Also, remote automatic control system used to control the flapper by the DSA to ensure blocking of diesel engines and the main propulsion motors during their mode of RDP and protection of diesel engines for certain limiting characteristics. Apart from a remote control for controlling diesel engines could use the local control panel located on the ends of the bow of diesel engines. Remote automatic control system greatly simplified the service during the work and is permitted to one person located outside the diesel motor, controlled diesel engines. The special features of diesel plant is and what their intake ducts are made of titanium alloy;
— A couple of main propulsion motors PG-141 (capacity each at 500 revolutions per minute and 6 thousand hp) and a pair of electric motors of economic progress of the PG-140 (capacity each at 155 revolutions per minute 200 hp);
-Rechargeable silver-zinc battery type 30/3, which consisted of four groups, each on 152 element. The greatest strength of the discharge current — 14 thousand amperes for 90 minutes. Most of the discharge capacity of the regime — 30 thousand ampere hours at a current of 250 amperes. Battery life of 35 to 40 cycles or conventional 12 to 18 months time. For the most modes of battery discharge provided for the closed cooling system with distilled water. Apart from the much larger capacity compared to a lead battery, silver-zinc allowed a break in the charges, as appropriate, incomplete holding them, nor sought refills during the warranty period of operation. The battery was equipped with a remote monitoring system at work, making it easier for its service. Due to the absence of a sufficient amount of silver in 1961, took the decision to restrict the use of rechargeable silver-zinc battery for approximately half of the series Project 651 submarines, and then the number of vessels with this battery was reduced to three. On the other submarines were established lead-acid batteries 60cm-P (ed. 422) at 448 e. (Each group 112 e.) The greatest strength of the discharge current of the battery — 9 thousand And within an hour, the maximum capacity of a long discharge mode • A 15 thousand hours at a discharge current of 250 A.
To control the propulsion motors used shields, which had a water cooling system and provide start, reverse, and other specified generator and motor modes. To maintain the purity of distilled water cooling, which directly depends on the insulation resistance of the control panels, propulsion motors and rechargeable batteries, water cooling system installed ion exchange filters. Rechargeable silver-zinc batteries, and cooling water control boards propulsion motors for Russian submarines were used for the first time.
The main armament of the submarine project 651 — missile systems S-5 and S-6. Containers designed for storing and launching rockets, interlocked and installed in pairs — one in the nose, the other aft of the cabin enclosure.
Missiles submarine on a design and circuit design provides the ability to single-launched cruise missiles P-5 or P-6 at least some of the container also holding chetyrehraketnogo volley sequence starts with 4-1, 3-2. In this case, exclude the possibility of firing various types of missiles during the 1st surfacing submarine.
Containers for the launch of missiles podymali at an angle of 15 degrees. The rise and imminent locking of containers, closing, opening, locking covers performed by hydraulic actuators. Hydraulic cylinders, which are located outside the body strong, connected to a single system hydraulics. Hydraulic cylinders, which are placed inside a sound body, connected to the hydraulic system common ship. This is done to prevent the ingress of seawater in general ship hydraulic system, as well as for corrosion protection of the executive. Start cruise missiles carried only provided that all operations are executed in prelaunch received sequence, including the operation of lifting and locking of containers and covers. In this regard, the control panels provide lock that prevents the launch of the missiles in the event of failure of at least one of the operations. Start scheme provides emergency discharge of faulty CD by starting engines. The submarine was able to lower the missile at any step of the prelaunch after closing lids or containers with lids open 1st of containers.
The composition of each container were:
— fire extinguishing system;
— gas analysis system of air;
— internal irrigation system;
— system gas analysis of air;
— ventilation system, gas cleaning, drainage, maintenance of air pressure;
— external irrigation system;
— heating system;
— Pressure measuring devices and temperature;
— Devices having water and determine its level.
Firing rockets carried out only from surface position when raised, the locked containers and lids open. Travel speed submarine with all this should not exceed 8 knots and the sea state less than 4 points. Reset the emergency rocket could be carried out under the same criteria.
The control system missile system S-6 allows to solve puzzles flight control and missile guidance using radar reticle on the target, which is within the boundaries or outside the geometric visibility of the wearer. Upon detection of multiple targets was possible to selectively damage by sending a cruise missile submarine on radar targets an
d reverse transfer of command of the selected target.
Determination of bearing and range missiles for F-6 performed shipboard equipment "argument" from data obtained from the reconnaissance, navigation aids as on submarines. The antenna system of "argument" — actually flat design, an area of about 10 square meters, with a protruding 1.5-2 meter area which is emitters. This antenna is installed on a rotating mast in the bow cabin enclosure. Antenna in the inoperative state of the factory in the machine enclosure cutting multiple switching operations and cowl mounted to the rear side of the antenna mast at the same, in this case, a frontal enclosing portion. Work rotator antenna design was reliable and it was coming for the following projects submarines.
To receive external target designation for the missile system from helicopters and airplanes equipped with submarine equipment "Success-U."
"North-A651U" — a control system S-5 — designed for missile guidance in the event of strikes on target area. For this purpose, it introduced the distance to the target, and other major features. In flight rocket managed by the autopilot. Height flew — about 400 meters, for all that its line of movement within the radio horizon adjusted from a submarine. After overcoming a rocket certain distance, determined the time counter and the inertial system, she dived down on goal. Estimated CHED when shooting at full range (around 500 sq m) was 3 thousand meters.
S-5 rocket in 1966 were decommissioned submarines of Project 651 and leaving only the P-6 missiles. Because a boat rented equipment that belonged to the P-5 missiles.
Torpedoes Project 651 submarines consisted of a 6-and 533-mm torpedo tubes in the nose (no spare torpedoes) and 4-compact 400-mm torpedo tubes in the stern (eight spare torpedoes). Bow torpedo tubes 533 mm are placed parallel to the center line, and feed an angle of 3 degrees to the center plane of the submarine. Torpedo tubes 533 mm provided the electronic fire and steam torpedoes, among which 53-56, 53-57, 53-58 and 53-degree days, a mass of 2200 kg at least 100 meters deep. Torpedo tubes caliber 400 mm provided the electronic firing torpedoes MGT and MGT-1-2 at a depth of 150 meters or less devices "Anabara" (jamming devices) at least 250 meters deep. On submarines, beginning with the K-156, install the unit charge 400-mm torpedo tubes feed. Recharge produced by electric trolley has automatic separation after planting torpedoes at the stops. Recharge time 4 torpedo tubes — about 30 minutes.
In the process of building submarines, 651-year project on the part of the courts in the 2nd compartment there were racks for 533 mm torpedoes. The main purpose of installing shelving was so in time of war, at the expense of habitat criterion of personnel, it was possible to take a spare twelve 533-mm torpedo for nasal TA instead of regular replacement of eight 400-mm torpedo for stern torpedo tubes. In this case, the number of torpedoes on the submarine was increased to 22 units. Loading 533-mm torpedo spare produced through torpedo tubes and specials. access holes in the bulkhead between the first and second compartments. These torpedoes were intended only to recharge the four torpedo tubes.
General shipboard equipment and systems submarine 651-year project in the main match torpedo submarines of Project 641, but later:
— Due to the large amount of supplies buoyancy diameter flow section of the column head blowing emergency ballast increment of up to 60 mm (641 in the courts of the project, he equated 32mm), it has become a prerequisite for that manual control valve emergency purging was difficult and it was replaced by a pneumatic.
Later it became clear that the pneumatic control accelerates the opening of the shut-off valve column that when the bypass air at one time he basks in the empty pipe and the presence of oil deposits on the inner walls of the tubes can cause an explosion of the oil vapor ("diesel effect"). Similar cases have occurred in the first generation of nuclear submarines (Project 659 and 675). For quick shut-off valves mounted on columns emergency purging changed to pneumatic valves, having a bypass device that regulates the pipeline emergency flushing rate of pressure rise;
— Hydraulic manipulators control the executive bodies in the hydraulic system were changed to electric spools, which were placed around the executive bodies and is operated with the remote control;
— Were installed stabilizer "Marble-2" as a stabilizer gyro pilot course "Granit-2".
Habitability conditions on the sub 651-year project has been significantly enhanced in comparison with the submarines of Project 641. All personnel ensured berths, located in the bow of the boat, in the main in the first and second compartments. Officers of the submarine was located in the cabins. Local climate conditions and the gas composition of the air at action stations and facilities provide a centralized system of marine air conditioning and ventilation, air-conditioning system in the field of physiological rest of the crew and at action stations, heating and so similar. General ship centralized air ventilation system serviced by one exhaust fan and a blow in (the performance of each 9.5 thousand cubic meters per hour), and had an air cooler and electric heater for heating or cooling outside air supplied to the interior.
Apart from this, at action stations and residential areas were established autonomous air coolers, who worked on the water or seawater on the so-called Working with cool water, which is cooled with 2 freon refrigeration system SPHM-FU-90 (performance of each 85 thousand kcal / hr).
At various points in the submarine to clean the air from various harmful gaseous impurities were filtered or scrubbing. The regeneration of the air produced plants RDU. They used gopkalitovye ammo boxes. AQL device was provided debris removal to depth of 200 m
Submarine 651-year project used propulsion system consisting of a nozzle guide and a low noise propeller screw. Full-scale acoustic, also running tests Project 651 submarines have shown that the introduction of the guide nozzle increment critical running speed by about 30%, and the propulsive factor of about 20%. Analysis of the results has permitted to conclude that the introduction of the propulsion system increased the critical ground speed by half compared with submarines without the complex. Through the use of shumozaglushayuschego and protivogidrolokatsionnogo coating, insulation from the hull devices, a new propulsion system, and other activities, the level of noise submarines came out lower than at other Russian diesel submarines, although it is not one hundred percent satisfie
d all the requirements of the Navy.
Construction and testing of submarines of Project 651 were accompanied by significant difficulties. The most important of them are:
1. Testing of diesel engines 1D43. At the head submarine diesel engines have been delivered to the Interagency Commission has been taken. Later, specifically on the submarine did not once work was carried out to modernize the individual components of diesel engines and to eliminate shortcomings.
2. The development of silver-zinc batteries for the first time applied to the Russian submarine. With the start of the test due to the small internal closures separate battery began to fail. Number BATTERY disconnected from the battery to the head of the submarine was 61 608 units, which is about 10 percent.
3. Lack of ability to carry out all the tests in the Baltic Sea, as there were no suitable depths for deep dives and sites for testing missiles. This required the relocation of submarines to the Northern Fleet in the Baltic with the transition around the Scandinavian Peninsula.
4. The test period the P-6. During the state. Test the boat in the Barents Sea were conducted tests of missile weapons, except for the hot race propulsion motor with the current layout of the P-5, which is performed in the Baltic Sea to the period from February to March 1963 during the industrial trials. After the races were held propulsion rocket engines each, and a joint missile race propulsion engines of the first and fourth container had a two-run missiles P-6 — single launch and run 2-missiles. In addition, a single run was carried out missile P-5. Firing missiles P-6 produced by the target-ship project 1784 from the 1st and 4th of containers in sequence 1-4. Firing missiles P-6 showed excellent results — all three vypushennye missile hit the target. A single P-5 launch held from the 2nd container in combat maritime field test site, with all this failed to establish the coordinates of the point of impact.
As a result, testing the P-6 found that a single firing missiles P-6 can be carried out at least some of the container of the submarine, and shooting with 2 missiles P-6 of the likely number 1 and number 4 in the sequence of 1-4 containers and number of 2 and 3 number of containers in a sequence 2-3. This sequence at the start of volley fire driven by the need to minimize the impact of missile propulsion engines operating at a prelaunch mode, rocket engines work, which will start from the adjacent containers, and the impact of flue gas propulsion engines and launch the rocket launch rocket engines work are in adjacent containers.
These phenomena are seen even during the first rocket launches the P-5 and, specifically, during the missile firing submarine of Project 659. At first, it was the view that unbalanced work propulsion engines during burst shooting too high resistance caused by the vapor vygorodok, due to their failure form. But the tests that were performed on Dual container spec. board in July-August 1960, showed that the chosen design and the shape of the vapor vygorodok work sustainer engines does not have a decisive impact. During these same tests, it was found that working sustainer engine soon to launch rockets sucked through the air intake part of the gases startovik rockets and propulsion motor that starts from the adjacent container, as needed stability of the rocket motor, which is being prepared for launch. Engine speed reduced by about 10-15 percent. To determine the activities that are necessary to ensure the volley fire rockets from 2-and more than volleys, shield Dual container converted into chetyrehkonteynerny universal shield that allows you to change the mutual accommodation 2-blocks adjacent to the gas outlet in their borders, which add-ons are allowed submarines had to armed with CD complexes P-5 and P-6.
Firing missiles P-5, P-5D, P-6 and P-7, which had a universal shield godoh in 1963-1964, showed the subsequent:
— work sustainer rocket engines form gas outlet does not have a significant impact;
— flue gas streams start the machine and launch the missile propulsion engine significantly affects the operation of the rocket being prepared for launch in the main due to the extremely high temperatures. Gas streams entering the air intake propulsion engines are becoming a prerequisite disruption of airflow and temperature rise of the compressor. This leads to a decrease in turnover and in some cases stop the sustainer engine which operates on a "full throttle";
— also off-gas streams missile act on the nose of the missile, which is near the container, the container back to the rocket launch and can bring her down.
According to the results of tests that have been conducted of the Interagency Commission of the Navy and the Supreme Economic Council, chaired by GCS Pustyntseva were given advice on sequence starts with a cruise missile submarine during burst fire, and on modes of work sustainer rocket motor, which is being prepared for launch. For submarines of Project 651-chetyrehraketnom volley of missiles at P-6 missiles recommend starting in the sequence 1-4-2-3. When substantially all of this interval increment between rockets 4 and 2 compared with an interval between 1 and 4, rockets, missiles and 2 and 3. Delays were 6-26-6 seconds.
During the industrial and state. Test head submarine was over 10 thousand miles on the surface and about one thousand miles under water. State acceptance commission head submarine 651-year project noted that "the main positive features of a submarine of this project are:
1. universal tools, making it possible to solve various puzzles;
2. good mobility on the surface and submerged;
3. Small zalivaemost superstructure at sea up to 9 points;
4. were significantly better habitability conditions for personnel in comparison with other diesel-electric submarines. "
Apart from this, the Commission has also been noted a number of shortcomings submarine, the most important of which were:
1. no reliable silver-zinc batteries 30/3 installed on the head submarine, and the inability to discharge the batteries low currents, which significantly complicates the management of propulsion that made it difficult to create maneuvers;
2. lack of standardized bortrazemov for missiles P-6 and P-5. With designs available bortrazemov their change during the transition from the P-5 to P-6 complex (also opposite) asked for 2 to 3 days (it should be stressed that after the removal of missiles P-5 to the issue of arms fell off.)
At the conclusion of their own state acceptance commission, said: "On the whole submarine 651-year project on their own weapons, ship systems, power plant and electronic weapons, devices and instruments is a modern ship, which in their tactical and technical characteristics superior to all existing diesel-electric submarines and is able to do a wider range of tasks. "
First five submarines with external bodies, which are used in the construction of Low magnetic steel, began to operate in 1962. But in September 1966 in one of the courts have found a huge amount of visible damage to the outer skin of the body in the form of non-through and through-cracks of different lengths around the head of ballast tanks. Surveys have found that all the light hull structures made of magnetic steel 45G17YUZ and are in contact with water, after 5 years of operation, subject to the emergence of non-through and through-cracks.
In view of the prevailing circumstances of the Navy and SMEs have adopted a number of joint decisions. For each project, submarines, in accordance with these decisions, has developed a set of design, technology and protection measures aimed at increasing the corrosion-mechanical strength of the outer hull, and the coming of strong external tanks, which are used in the manufacture of steel 45G17YUZ. Have also developed a series of instructions and guidelines to remedy deficiencies (after the elimination of defects magnitude of the magnetic field of the submarine due to the specification for the construction of the submarine was not guaranteed). Typically, these works were combined with another upgrade or repair submarines.
Modifications submarine project 651/651-K Juliett class.
The submarine K-81, which in 1965 was put into operation, the project added two 651-K. The vessel was equipped receiver antenna system equipment gallakticheskogo also targeting the CD "Killer Whale-B." Such a system previously passed tests on the submarine K-68 of the same series.
On retrofit submarine K-68 in June 1969 in the Barents Sea were tested prototypes of special containers for future rescue chambers pop submarines. Study skills, and ways of creation of rescue chambers began SPMBM "Malachite", along with the ACC Navy in 1964, when there was a question on the emergency and survival equipment during deep dives head-subs dive depth which leaves more than 400 meters. Tech. design and detailed engineering was done in 1967 SPMBM "Malachite", and the construction of a pair of containers carried out in 1968 at the "Red Sormovo".
At "Red Sormovo" in 1985 under the project 651-E converted submarine K-68. Its a trial basis supporting equipped compact nuclear power plant VAU-6.
Some subs 651-year project in the late 1970s. (Once with SSGN 675-year project) were rearmed with anti-P-500 "basalt", although by that time their actual combat stability was already very confusing.
The program of construction of submarines.
Just supposed to build 72 submarines of Project 651, but in the long run, the program substantially reduced. Head submarine (K-156, serial number 552) laid on the Baltic CVD Ordzhonikidze (№ 189) 16.11.1960 and launched on 31.07.1962. Mooring tests were started 27.08.1962 and factory tests, which were carried out in the Baltic Sea and Tallinn — December 22, 1962. Submarine May 21, 1963 was presented to the state. The tests are completed December 10, 1963, then signed the acceptance certificate. At the same plant in 1964 built a second boat 651-year project, and the other 14 ships built in the period from 1965 to 1968 at the "Red Sormovo» (№ 112) in Gorky.
Project 651 boats priemuschestvenno were part of the Northern Fleet. The main place of use is the Mediterranean Sea. Later they were transferred to the Baltic and Black Sea fleets, as an act of diesel-electric submarines with cruise missiles on data theaters further meet the combat abilities of ships — only in enclosed seas, and in the near field can be reliably shield them from anti-submarine forces. Initially, all submarines of Project 651 were classified as cruising, but in July 1977 they reclassified in BPL. These submarines were designated in the west Juliette class.
Overall, 651 submarine-year project (as well as 675-year project) finished in the navy of the evolution of the Russian Union of submarines armed with surface-launch the CD. These ships from the 1980's they started to be output from the Navy and by the early 1990s, they passed on the scrap heap. With all of this boat — the B-24 and B-77 — sold to the west, where they were turned into museum exhibits.
