Chapter 111

readx; Zhao Fengyan glanced up at the visitors standing in the bridge and facing her, then turned on the slide projector, pointed to the battleship on the screen, and said to all the visitors: "First of all, what I want to talk about next is the ship under our feet." First, according to the unified standards for escorting antisubmarine destroyers in the world today, destroyers take ocean-going escort and anti-submarine warfare as their primary combat objectives, followed by ship-to-ship operations, but our destroyer follows completely opposite standards, so we take a completely opposite direction, first taking ship-to-ship combat as the primary combat objective, and then anti-submarine and ocean-going escort. Pen, fun, pavilion www. biquge。 info”

Among the visitors, an officer of the 19th Route Army wearing a long coat who did not know his name said loudly to Zhao Fengyan: "May I ask Captain Zhao, since the destroyer you mentioned takes ship-to-ship combat as the first priority, in fact, my brothers and I want to know the specific situation of this battleship." ”

After hearing this, Zhao Fengyan politely asked the officer of the 19th Route Army in a long coat: "Hehe, I don't know what this brother's name is, and what position he holds." ”

The officer in the long coat replied with a military salute: "Captain Zhao, please forgive me for my rudeness just now, brother Zhang Zhanluan is the commander of the 19th Route Army, the 60th Division, the 119th Brigade, the 1st Regiment, and the 3rd Battalion, please can you answer my question." ”

Zhao Fengyan didn't care about such a dispensable trivial matter, so she said: "It turned out to be Camp Commander Zhang, I will mention the problem you just said, please listen to the lecture with peace of mind." The 3rd battalion commander Zhang Zhanluan stopped speaking after hearing this, and listened quietly to the beautiful captain explaining the battleship under his feet.

Zhao Fengyan once again pointed to the enlarged internal structure section of the Thorn Flower class on the curtain and said to the people on the battlefield: "Second, our Thorn Flower class is completely different from any destroyer in the world in terms of structure, first of all, this battleship adopts a thick double-body structure, with an armor thickness of between 270 mm and 355 mm, and uses high-strength special light titanium alloy armor steel. To a certain extent, it can reduce the weight of the whole ship, and the two-hull structure of the warship is shallower than the average ship in terms of draft, as we all know that most of the destroyers in the world today have a draft between 3.9-2.7 meters, but our 'Thorn Flower class' draft is far less than all the destroyers in the world today, only less than 2.3 meters of draft. This is also due to the good construction of the catamaran, which can have more space, which is convenient for future modifications to maximize the strengthening of the warship itself, so that its seaworthiness and stability at sea can reach the best state! ”

Zhao Fengyan paused again, looking at the people in front of her who were attracted by the topic she was talking about without making any sound, she continued to point to the enlarged frontal, floor and side drawings of the ship on the curtain and said: "Third, the appearance of the 'Thorn Flower Class' is atmospheric and beautiful, but the pointed bow, the thick protective armor plates on the side and upper deck make it look like a cruiser.

Due to the arrangement of the deep projection slide, the stern appears to be slightly upturned and collapsed, and the entire double hull is a hybrid skeleton structure, using three layers of bottom, and we use a new type of seamless welding method for ships. From both sides of the keel to the main deck, 32 longitudinal skeletons are arranged from low to high, 32 on each side, extending along the entire hull from bow to stern, and 30 longitudinal skeletons are arranged on the main deck plane as deck support structures. It has a transverse skeleton of 420, including 28 watertight partitions and 14 oiltight partitions, and the transverse skeleton is spaced at 53cm.

The 28 watertight partitions divide the hull into 30 watertight divisions, and all watertight hatches are set up above the first platform deck to ensure the watertightness between the various divisions of the hull under the waterline, among which the two watertight partitions located in the ribs of No. 148 and No. 314 constitute the front and rear walls of the power compartment respectively, and no hatch is opened, and can only enter the boiler room and engine room through the opening on the main deck, so that the entire power compartment becomes an independent large watertight division, and strengthens the safety of the power system when the hull enters the water. In addition, an oiltight bulkhead for separating the fuel tanks provides additional watertight protection. ”

Zhao Fengyan pointed to the power system structure diagram at the tail of the ship and said to everyone: "Fourth, outstanding maneuverability, high speed and long-lasting endurance have always been the goal pursued by destroyers, and the 'Thorn Flower Class' is designed to not only focus on the needs of new capital ships and fast aircraft carriers, but also to use as a sea raider, specifically to deal with and harass ships with weak armor, slow or unprotected ships to break the engagement, and set the speed index at an altitude of 57 knots.

In the case of a significant increase in tonnage scale compared with today's destroyers, the Thorn Flower class needs a more powerful and energetic heart, and its power system no longer continues the basic configuration of today's destroyers, but is composed of four high-performance heavy gas turbines R55000, using four axles and four propulsion, but the increase in the output power of its main engine far exceeds that of the current ship to obtain higher speed.

The main engine of the Thorn Flower class is four variable speed gas turbines, arranged in two independent engine rooms before and after the two ships, each main engine is composed of a high-pressure turbine, a cruising turbine and a low-pressure turbine (the later type adds a reversing turbine), the crew is connected to the propulsion shaft through a gear reducer, in which the main engine of the left wheel nacelle drives the left two propulsion shafts, and the main engine of the right wheel nacelle is responsible for driving the right two propulsion shafts, and then drives four five-blade titanium alloy propellers with a diameter of 1950 mm. The power to propel the operation of the main engine comes from the four R55000 gas turbines equipped with two sets of two arranged in two separate engine rooms of the hull, arranged side by side, through the front and rear flues, and finally exhaust the flue gas from the only chimney on the ship, and the engine rooms of the left and right hulls have independent fuel pumps to supply fuel to the boilers. In terms of the layout of the power compartment, the Thorn Flower class adopts the mode of side-by-side arrangement of the two-wheel engine room of a unique destroyer, and the thick protective armor increases the safety factor of the power system, so that even if one of the gas turbines in a single engine room is hit and damaged in battle, it will not cause the whole ship to lose its ability to sail. The main control room of the power system is located in the nose engine room. ”

After introducing the power system, Zhao Fengyan jumped directly to the power system of the whole ship and said: "Fifth, the power system of the Thorn Flower class consists of four high-power generators connected to the gas turbine and two large emergency diesel generators, the former includes two 2,500 kilowatt/4,500 volt generators and two 400 kilowatt/1,200 volt generators, and the latter is two 1,000 kilowatt/4,500 volt diesel generators, which are used to provide emergency power when the whole ship loses power. She looked at the other people in front of her again, and knew that these people were a little impatient, so she tried to compress the ship's information as much as possible.

Zhao Fengyan then pointed to the device of the ship's bridge and mast and said: "Sixth, the Thorn Flower class is the only large destroyer equipped with radar among all ships of the world's navy, and every escort destroyer anti-submarine ship we built is equipped with a fairly complete radar system when it is in service, including air search radar and sea search radar, the air search radar equipped with the Thorn Flower class is mainly KS (air search)-1 type, with a wavelength of 8160 mm, and the flat panel antenna placed on the main mast platform weighs 408 kg. The dimensions are 2120x2590 mm, the rotational speed is six seconds / week, the transmitting power is 2000 kilowatts, the operating frequency is 2000 MHz, the maximum detection distance to the air is 440 kilometers (for bombers flying at an altitude of 5 kilometers), the ranging accuracy is 11 meters, and the angular measurement accuracy is two degrees. The KS-1 radar is equipped with a 45-inch PPI flat panel display and a 15-inch A-type oscilloscope on the main console, which is very easy to operate.

The performance of KS radar is the most outstanding in all current radar equipment, equipped earlier, in addition to the KS type air radar, the Thorn Flower class is also equipped with HS (sea search) type sea search radar, which is currently the world's first kind of naval equipment does not have the first microwave sea search radar, HS radar full set of equipment weight 1996 kg, wavelength 60 cm, transmission power 500 kilowatts, operating frequency 30000 MHz, with the arc antenna weight of 372 kg, size of 1120x1260 mmIt is very lightweight, suitable for destroyer installation, the antenna speed can be adjusted, it can rotate four, eight or twelve times per minute according to different situations, the maximum detection distance for large ships is 265 kilometers, and the maximum detection distance for small ships is 200 kilometers, and it can also find low-flying enemy aircraft, with a ranging accuracy of 40 meters, an angle measurement accuracy of two degrees, and its main console is equipped with an 18-inch P.Pi flat panel display and a 10-inch A-type oscilloscope. After we have improved it again, the HS radar also has the function of navigating in narrow waterways, which can be called a multi-purpose machine. ”

Cai Tingkai listened to it for a long time, and found that the content of the female captain in front of him was too professional, and he also saw that many people around him, including Chen Jingtang, were all stunned when they listened to this introduction, and he had talked with some domestic naval captains and observed the ships all year round, but he could find some clues from the knowledge of ships, but the soldiers around him who were on land all the year round did not understand this, and they were also dizzy when they heard it. So he had no choice but to speak: "Captain Zhao still talks about its key armament displacement size, as for the others, can we talk about them later." ”

Cai Tingkai still knew what Long Bazun wanted to say, so Zhao Heng, who was standing aside and looking at the information in his mind, suddenly spoke and persuaded: "Commander Cai and the brothers of the Nineteenth Route Army, please rest easy, Captain Zhao is about to talk about the issues you are concerned about." Can you wait for Captain Zhao to finish this topic. ”

At this time, without waiting for Zhao Fengyan to explain, Zhang Zhanluan, the commander of the third battalion, interjected: "What Captain Zhao said is too professional, and the other brothers around me have no way to understand, I hope that Captain Zhao can explain it simply and clearly, but I look at the drawings of this battleship, and there are still many things I don't understand, I hope Captain Zhao can solve the doubts in our hearts for those of us who are mud legs on land." Zhao Heng on the side thought to himself, it seems that the clones are still slightly insufficient, and in the future, they will have to find a way to upgrade and evolve in order to become the same as ordinary people, with seven emotions and six desires, otherwise, it will cause people to be suspicious after a long time.
