Description

This invention relates to the Navy and is used in a submarine, with its various tactical position.

As you know, the control of a moving submarine in the vertical plane is carried out by horizontal rudders, when the layer on them is capable of holding the submarine at a given depth. But as the speed of the submarine decreases, it becomes difficult to control. In this case, the submarine will float or sink depending on its residual buoyancy, i.e. from the one she had to the critical speed, positive or negative / cm. lit. Bolgarov N.P., Tales of a Submarine, p. 53, 1960 /.

The submarine, when moving in a submerged state, as a rule, always has positive buoyancy, compensated by horizontal rudders. Therefore, when stopping, the submarine cannot hover at a depth and begins to surface. It is possible to prevent ascent only by taking, in addition, a certain amount of water into the equalization tank until a balance is reached between the weight of the submarine and the weight of the water displaced by it, i.e. until zero buoyancy is achieved. To save it in this way is irrational, since the submarine in this case should alternately acquire positive or negative buoyancy; achieved from the continuous operation of the pump, designed for pumping and pumping water from the equalization tank / cm. The journal "Foreign Military Review", 1981, No. 10, p. 65 /.

The device performing this procedure is known as a depth stabilizer, consisting of rather complex, sensitive and capricious devices / cm. lit. V. Infantiev. Stand in places to dive! p. 38, 1977 /.

In addition to these shortcomings in the management of the submarine, there are still disadvantages in regulating the trim by pumping water from one trim tank to another, and this requires a lot of time. Particularly strong trim occurs when firing torpedoes. It will last until the torpedo replacement tanks are filled. And if in this case the trim is not quickly settled, then the submarine can jump out of the water / cm. lit. Bolgarov N.P., Tales of a Submarine, p. 53, 1960 /. The disadvantage of modern submarines is that they cannot shoot torpedoes at a target without movement, since the submarine, being at periscope depth, tries to keep it horizontal rudders when moving, without using an equalization tank.

The aim of the present invention is to remedy these disadvantages and increase the controllability of the submarine when submerged both when stationary and in motion.

This goal is achieved by the fact that to keep the submarine at a given depth and to trim, in the location of the keel in the fore and aft parts propellers are installed, the axes of which are perpendicular to the inside of the hull of the submarine and connected to reversible electric motors.

Figure 1 shows the boat, with some of its parts: the hull of the submarine 1; propeller propulsion 2; vertical steering wheel 3; horizontal steering wheel 4; battlehouse 5; periscope 6; stern propeller 7; bow propeller 8; vertical axis 9, 10; feed reversible electric motor 11; bow reversible electric motor 12; keel 13; feed reflector 14; nose reflector 15 / cm. figure 2 and 3 /.

The submarine control circuitry consists of the following elements / cm. figure 4 /; knife switch 16; relay 17; electromagnetic starters 18, 19; depth gauge 20; arrows 21 depth gauge; depth gauge scale 22; protective glass 23 depth gauge; fixing arrows 24 depth gauge; switch 25; knife switch 26 trim; power supply unit 27; fuse 28.

The depth gauge 20 is similar in appearance to the aneroid-barometer.

A device for holding a submarine at a given depth acts as follows.

Assume a submarine / cm. figure 1 / you must hold, still, at a depth of 100 m. There may be two cases: the first when the submarine is at a depth of less than 100 m immersion, and the second when it is immersed more than 100 m

1st case. The submarine is at a depth of less than 100 m. Then the depth gauge arrow 24 is fixed, on a scale of 22 it is set at 100 m; the switch 25 is turned on; circuit breaker 16 is switched to the dive position / lower position of the circuit breaker /, a chain is formed: + plus, contacts of the circuit breaker 16 of the lower position, contacts of the starter 18 1-3, motor 11, contacts of the starter 19 1-3, contacts of the circuit breaker 16 of the lower position, minus -.

In parallel with the electric motor 11, the electric motor 12 is turned on, along the circuit: + plus, the contacts of the knife switch 16 of the lower position, the contacts of the starter 18 '1-3, the contacts of the knife 26 1-5, the motor 12, the contacts of the knife 26 2-6, the contacts of the starter 19' 1 -3, contacts of the knife switch 16 of the lower position, minus -.

The propellers 7, 8 will begin to rotate from the electric motors 11, 12 towards the submersible of the submarine.

2nd case. The submarine is below 100 m. There is also a fixing arrow 24, on the scale 22 it is set at 100 m; the switch 25 is turned on; knife switch 16 is translated to the ascent / upper position of the knife switch /. When switching the knife switch 16, there is only a change in the direction of the electric current supplied to the electric motors 11, 12; from this, the electric motors will begin to rotate in the direction of the submarine's rise.

When the arrow 21 of the depth gauge 20 closes with the locking arrow 24, a chain is formed: + plus, arrow 21, locking arrow 24, relay coil 17, switch 25, minus; the relay 17 is activated and its contacts 17 1-2 closes the circuit of the electromagnetic starters 18, 19: + plus, the contacts of the relay 17 1-2, the windings of the starters 18, 19 minus -; starters operate and with their contacts close the circuit of reverse rotation of electric motors 11, 12; + plus, starter contacts 18 '1-2 and 19' 1-2, electric motors 11, 12 minus -. On this chain, the electric motors will begin to rotate back to the ascent of the submarine. The contacts of the depth gauge 21, 24 will open, the relay 17 will be de-energized and its contacts 17 'will return to their original position, then the whole process will be repeated initially. And this means that the submarine will be kept at a given depth of 100 m.

In the 2nd case, the whole process will be repeated as in the 1st case, only the switch 16 should be switched to the ascent / upper position of the switch /.

In the event of a trim, the switch 26 is placed in the "trim" position; contacts 1-3, 2-4 are closed; electric motors 11, 12 will begin to rotate in different directions. In this case, the knife switch 16 is trimmed.

In cases where it is not necessary to keep the submarine at a predetermined depth motionless and not to adjust the trim, switch 25 must be turned off.

This invention effectively operates on small and medium-sized submarines / 150-500 tons and 500-1500 tons /, in which a change in dead weight sharply affects their buoyancy / cm. lit. V. Infatiev, Stand in places to dive! p. 33-39, 1977 /.

The submarine during sailing should have positive buoyancy, excluding it when it lays on the ground.
