The submarine fleet led by Tian Ergou has more than 500 people, all of whom are carefully selected elites of the Zhongyong Army Navy. Initially, four ships use the newly invented diesel engine-electric motor dual propulsion system, with a surface speed of about 10 to 15 knots.
A submarine with an underwater speed of 6 to 8 knots.
The weapons mainly include artillery, mines and torpedoes. The submarine fleet mainly consists of about 300 technical operators, and about 200 people are the frogmen and minelayers of the fleet.
So Tian Ergou continued to carry forward his spirit of hard work and started secret adaptive training with the submarine fleet. As the saying goes, what kind of general leads what kind of soldiers, that is true at all.
From the moment the submarine fleet was handed over to Tian Ergou, his soldiers were as talkative as Tian Ergou, but they were so powerful at killing every enemy that they were nicknamed the Mad Dog Fleet by other brother troops.
But then again, I don’t know how much effort Zhou Yu spent on improving the performance of the submarine.
Zhou Yu started the painstaking submarine project in Hawaii. Four submarine production lines were imported from Germany, three were installed in Hawaii, and one was installed in Taiwan. At that time, Zhou Yu required all shipyards, submarine production lines, etc. to be constructed in a closed manner.
to improve confidentiality.
The submarine designed by Zhou Yu is a double-hulled submarine. The hull is divided into an inner shell and an outer shell. The inner shell is a steel pressure-resistant hull to ensure that the submarine can withstand the hydrostatic pressure corresponding to the depth when moving underwater; the outer shell is a steel
It is a non-pressure-resistant hull and does not withstand seawater pressure.
Between the inner shell and the outer shell are the main ballast water tanks and fuel tanks. The submarine hull has a streamlined cigar shape to reduce resistance during underwater movement and ensure good maneuverability of the submarine.
Zhou Yu divided the pressure-resistant hull into three sections: bow, midship and stern, which are divided into six sealed cabins. The cabins are equipped with control and command positions, weapons, equipment, devices, various systems and crew living facilities.
To ensure that the crew can work, live and fight normally.
Zhou Yu installed two 350mm torpedo launch tubes in the torpedo cabin. There is a pressure-resistant command room in the middle section and a non-pressure-resistant command bridge on the water. In the command room and its enclosure, there are
Working periscope, snorkel etc.
The spatial location of lifting devices for antennas such as radio communications, radars, radar reconnaissance and warning receivers, radio directionfinders, etc. was reserved. This move puzzled other technicians, and Zhou Yu did not explain it.
The bow and stern of the boat are also equipped with pitch balance water tanks. By adjusting the water volume in the bow and stern balance water tanks, the trim that may occur when the submarine is underwater is eliminated. There is a trim balance tank at the bow (or command room enclosure) and at the stern.
The horizontal elevator is used to control the submarine's transformation and maintain the required submersible depth. The stern of the boat is equipped with a propeller and rudder to ensure the submarine's navigation and course change.
Using diesel engines and electric motors as the power source for submarines, Zhou Yu went to see the progress of Rudolf Diesel's diesel engine development and found that a diesel engine for ship engines was about to be invented.
Diesel engines need enough oxygen to work underwater, so Zhou Yu invented the breathing tube. The breathing tube increased the submarine's submersible capability and allowed the diesel engine to be used underwater without worrying about lack of oxygen.
In fact, the basic structure of the breathing tube is very simple. It is an extendable breathing tube that guides the outside air to the diesel engine, and the generated exhaust gas is also discharged through the breathing tube. However, just such a small thing can make the submarine
The combat capabilities increased geometrically.
In addition, a pipeline is added to prevent seawater from entering and to remove the incoming seawater. By using a breathing tube, the submarine can use the diesel engine at periscope depth, so that the submarine does not have to float to replenish power.
The total length of the boat is about 52 meters, with a displacement of 320 tons. Its weapons mainly include artillery, mines and torpedoes. The diesel engine has a power of 120 horsepower and the battery power is 45 horsepower.
When sailing on the water, powered by a diesel engine, the speed can reach 18 nautical miles per hour and the endurance is 4,500 nautical miles.
When submersing underwater, when powered by an electric motor, the speed can reach eight nautical miles per hour and the endurance is 350 nautical miles. When powered by the diesel engine, the speed is 11 knots per hour and the underwater endurance is 1,600 nautical miles.
Each boat has a crew of forty-five, and its weapons are two 350mm bow torpedo tubes (with eight torpedoes) and two artillery pieces (one forward and one aft). The artillery aiming is controlled by steering the submarine hull against the
Accurate target. Each boat can launch torpedoes underwater, sail smoothly on the water, dive quickly, and maneuver flexibly....
When Zhou Yu was drawing out the drawings, he asked the base's four submarine production lines to start construction. When Zhou Yu was almost ready, Rudolf Diesel's diesel engines for marine engines were also developed and production began.
Now that the Zhongyong Army has precision machinery from the United States and Germany, as well as a large number of various technical talents who have returned from training in the two countries, Zhou Yu is ready to build a May 4th pistol that is low-cost and easy to mass-produce.
The May 4th-type 7.92mm pistol is used by grassroots commanders and special forces for self-defense and attacking enemies at close range. The effective range is 80 meters and can also shoot within 150 meters. The pistol uses 7.92mmx5.
7mm pistol ammunition.
The May 4th pistol adopts the short recoil recoil principle of the barrel, the locking method is barrel swing type, and the magazine capacity is eight rounds. The whole gun consists of a barrel, an upper sleeve, a lower sleeve, a recoil device, and a trigger.
Composed of magazines.
Its safety device is a hammer safety, there is no manual safety, and it only has a hammer semi-cocking safety. The gun is also equipped with an empty chamber and hook mechanism.
Its magazine catch is located on the left side of the grip, behind the trigger. Remove the magazine, pull back the slide, eject the bullet, check the chamber through the ejection window, release the slide, and pull the trigger.
But Zhou Yu will not just be satisfied with the May 4th pistol, because the May 4th pistol has obvious weaknesses, its shooting range and service life are short, and it is easy to jam, so Zhou Yu also developed another pistol that does not jam.
Wheel pistol, also called revolver.
There is also a deluxe version of the May 4th pistol, that is, the 1911-type pistol. The cost of the May 4th pistol is very low, and many of the gun's structures are simplified. The 1911-style pistol has a large caliber, is expensive to make, and is bulky, with a total weight of 1.13
kg, small ammunition capacity, seven rounds.
All three pistols use 7.92mmx5.7mm** smokeless ammunition.
Zhou Yu also plans to sell revolvers and luxury May 4th pistols to the Germans.
At the same time, he also prepared an automatic pistol for his troops. An automatic pistol is a pistol that can be reloaded into the chamber under the action of gunpowder gas during shooting. The automatic pistol has a caliber of nine millimeters and a length of two hundred to three hundred millimeters.
, weighing about 1,800 grams.
Named the Black Star Pistol by Zhou Yu, it has the characteristics of fast reloading, large ammunition capacity, fast firing rate, and high power. Some fully automatic pistols (submachine pistols) in later generations can be equipped with shoulder rests when necessary and can be held with both hands.
When shooting from the shoulder, the effective range can be increased to 150 meters. It is not possible to build it under Zhou Yu's current conditions. It will be OK when the electric welding machine comes out.
The shoulder stock added to the Black Star is usually used as a gun case or other accessories (such as daggers, etc.). When firing continuously, the firepower is fierce and the rate of fire is fast. Some fire rates are as high as 110 rounds/minute, and the ammunition capacity is usually eight rounds.
In addition, Zhou Yu also developed a 20mm large-caliber fully automatic gas-operated machine gun. This machine gun was named the 1814 heavy machine gun by Zhou Yu. Its effective range is more than a thousand meters. When shooting in the air, its effective range
The range is more than 2,000 meters, the sight range is more than 3,000 meters, and the maximum range is more than 7,000 meters.
Zhou Yu also developed and adopted warheads with combination effects such as armor-piercing bombs, incendiary bombs, tracer bombs, instantaneous explosive bombs, and explosive bombs. The machine gun mounts were also simultaneously developed into: tripod type, wheeled type, and wheel type.
In addition, Zhou Yu also developed a fully automatic gas-guided light machine gun based on the Type 1814 machine gun, which was named the Type 1814 light machine gun by Zhou Yu. For the Type 1814 machine gun, Zhou Yu also specially invented the arc ruler and optical aiming
The mirror cannot be produced for the time being.
In order to pursue mobility and shooting power, Zhou Yu made the gun weigh 5 kilograms without ammunition, the total length of the gun is 1,000 millimeters, and the effective range is about 800 millimeters.
In order to reduce the pressure on logistics, the ammunition uses Mauser 98b** smokeless 7.92 mm x 5.7 mm, which is common with Mauser 98b, revolvers, and Black Star pistols. The service life of the barrel is 30,000 r.
In order to make the piston heat-resistant, Zhou Yu also developed chromium-silicon-molybdenum alloy steel, and required other units to use chromium-silicon-molybdenum alloy steel for all heat-resistant weapons in the future, including various barrels and barrels.
The receiver used by Zhou Yu's current weapon is a metal plate receiver forged by a heavy machine, which is very expensive to make.
However, this will be easy to adapt to when machine-made receivers appear in weapons and equipment in the future. In addition, you can cultivate your own skilled workers and high-precision machinery manufacturing capabilities.
Zhou Yu quickly applied for world patents, and also applied for world patents for pistols and machine guns, as well as world patents for alternating current, three-phase asynchronous motors and bladeless fluid turbine generators.
Because of these machines, Zhou Yu plagiarized and provided specific technical data and drawings. Basically, there is nothing to improve in terms of manufacturing process. The only things that need to be improved are the size and power.
For manufacturing plants such as diesel engines, gasoline engines, steam engines, generator sets, and electric motors, Zhou Yu had already prepared a series of processes such as early machinery and factory buildings, and was just waiting for the rice to be ready.
Zhou Yu has been busy recently: submarine production base, shipyard and various supporting manufacturing plants, running around non-stop. The technical workers have all returned from training in the United States and Germany.
They need Zhou Yu's help to continuously improve their capabilities, process technology, etc., while Zhou Yu, the technicians and engineers from other countries, simply did not use any of them in order to prevent leaks.
The skilled workers of our own nation have been strictly selected by the Zhongyong Army and trained in patriotism and ideology. In addition, they have all signed lifelong confidentiality documents. Even their families do not know the specific work they do.
Zhou Yu's main purpose of doing this is to try to maintain his technological leadership, and to have a few more amulets as a backing, which makes him feel at ease!
