The installation of Type 5000 radar on a 307-ton destroyer is basically the upper limit, and the four-sided array phased array radar basically cannot be installed, unless the warship does not install guns or missiles.In view of the fact that the Shanghai Ship Design Institute has accumulated a variety of ship designs and hull structure designs of different tonnages, it is simply a little bolder, no longer enlarge the destroyer ship type, but start from scratch.

The design plan of the guided missile cruiser was born in this way, and now the basic hull design is completed.There are two plans for the power system. The first plan is the 56-horsepower steam turbine of the Type 72000 destroyer, with a maximum speed of 28-29 knots.

The second option is the gas turbine being developed in Chengdu. The maximum output power of the current test model is 22000 horsepower. If four gas turbines are installed, the maximum output power will be 4 horsepower, and the maximum speed will not be lower than 88000 knots.

The worst plan is to use steam turbines-the Navy said that this speed is acceptable, and in this case, the project was started.

If this type of guided missile cruiser starts construction, it will also be the largest warship in Chinese history, with a standard displacement of 10140 tons and a full load displacement of 12700 tons. It can be regarded as the two Dingzhen ships of the Beiyang Navy more than 70 years ago.

"The standard displacement is 10120 tons, just stuck on the line of 1 British tons (10160 tons). Mr. Makino, is this your professional habit?" Tang Hua asked.

Makino Shigeru: "I don't know either. I always involuntarily adjust and cut the weight of each subsystem in the stage of hull design to aggregate weight."

……

The development of the Sixth Machinery Bureau (Ship Industry Bureau) of the Ministry of Machinery Industry was accelerated from 1953.Throughout the First Five-Year Plan period, the Bureau of Shipbuilding Industry had bumps and bumps and repeatedly entered unfamiliar fields, but finally completed a step in its own shipbuilding and design capabilities according to the master plan.

In 1953, the US-made Fletcher-class and Keeling-class destroyer projects were launched;

1954年11月由苏联提供零部件，在上海江南造船厂和沪东中华造船厂组装建造56型驱逐舰。苏联专家提供的流程是14个月船台建造周期+12个月舾装，不过中间出了一点小麻烦……江南造船厂在船台建造阶段花了20个月，沪东中华花了21个月，分别在1956年7月和8月下水。

After the two assembled and built Type 56 ships were launched, two more ships, No. 2 and No. 3 ships, were started on the slipway.The parts are half imported and half self-made, and China has made some modifications to the design drawings, mainly to install a 4 radar.

鉴于1、2号舰建造时出的一堆子麻烦，援华的苏联专家是没脾气了，3号和4号舰只要求两个造船厂能在18个月完成船台建造就行。

This time, both Jiangnan and Hudong-Zhonghua are very competitive. After all, the tuition fees that should be paid have been paid on the No. 1 and No. 2 ships, and they cannot fall into the same pit twice.

At the outfitting wharf of the Jiangnan Shipyard, Ship 113 has been launched from the berth, and is now being tied to the wharf to install some upper-level equipment and parts, while being installed and being debugged. The construction stage of the berth of the 111 ship was delayed, but the outfitting period was still 12 months, and it was completed on time as planned, so the outfitting period of the 113 ship should still be guaranteed.

However, even if the construction period can be guaranteed, the completion and delivery of the 113 ship will not be until February 1959.

……

"The guided missile cruiser has a total length of 180.5 meters, which is more than 20 meters shorter than the Kaohsiung class; the maximum width is 20 meters, which is equivalent to the Kaohsiung class; the displacement is lighter than the Kaohsiung class before the unmodified weight increase. Of course, the main bridge and superstructure are in style. It is slightly similar to the Kaohsiung class, but it is not an imitation version of the Kaohsiung class."

In the Ship Design Institute, Shigeru Makino explained the design idea of ​​the current plan.

"There is a single-barreled 1mm gun on the front deck... I have to say that this may be the weakest gun fire I have ever designed. Behind the main gun is a 100-unit general-purpose missile launcher and a small-caliber anti-aircraft gun. The bridge is as wide as the hull, so no shipboard armaments are installed."

"A 64-unit general-purpose missile launcher is installed on the platform behind the chimney, and a hangar and a helicopter platform are installed at the stern. A short-range ship-to-air missile launcher is installed above the helicopter platform."

"Very good, this layout is very coordinated. The rest is to correct some small design flaws, and try not to bring the flaws to the ship." Tang Hua said.

"Minister Tang, the Type 56 destroyer has four 130mm guns. If we build a warship of more than 1 tons, we only have one 1-mm gun. Is it too exaggerated?" Li Fuli said.

Tang Hua: "Commander Xiao of the Navy has seen the plan, and he said it's okay, so he will continue to push forward. In fact, the space on the front deck is a bit wasted. If the underwater part of the front of the hull can be fuller, the front 64 units can be installed on the deck, and 128 launch units can be installed on the whole ship.”

Shigeru Makino: "If you can give me a mainframe with 10 horsepower, I can make its line fatter."

Tang Hua: "Then it's settled. When the 10-horsepower main engine appears, you will be responsible for fattening the hull. In addition to the line shape and structural design, the radar system and electromagnetic compatibility of this ship may have to be carefully planned. Pan Jingfu, you seem to be in charge of this aspect?"

Pan Jingfu: "The cruiser's electromagnetic distribution is too messy, and I don't know what to do now. The main radar system on the ship is the 308 phased array radar. There is also a ground-wave sea detection radar installed on the bridge. I have thought about these two radars for a long time, but I still think they cannot be turned on and working at the same time.”

Li Qiang: "The characteristics of the ground wave radar and the 308 radar are indeed similar, so let's forget about these two radars first."

"Then there are 3 ship-to-air missile tracking radars on the ship, 1 at the front and 2 at the rear, a tracking radar for short-range ship-to-air missiles, a low-altitude search radar, a gun-sighting radar, and a backup two-coordinate air tracking radar. Radar, a navigation radar... and a fire control radar for small-caliber antiaircraft guns, and a clean frequency band for a 'satellite antenna'. What is a satellite antenna?"

Tang Hua: "An ultra-short-wave high-capacity communication frequency band will be known in a few years. ... From this point of view, the ship research institute should expand the building by the Taihu Lake. Not only will the 308 radar be installed, but the cruiser will also need to install it. Radar and radio systems, all installed on it, to see if they work together."

……

Is this ship a conventionally powered version of the Long Beach?Is this "earthy" Ticonderoga?It's hard to describe anyway.

In the large-scale surface ship development planning demonstration report drawn up by the Bureau of Shipbuilding Industry, the operational positioning of this type of ship is "in Nansha, east of Taiwan and other sea areas close to the limit combat radius of our shore-based fighter jets, serving as the air defense of the sea destroyer formation. core and maritime command center".

In the event of a large-scale sea invasion targeting our country, the cruiser can be configured in a slightly forward position, and the area anti-aircraft missile can effectively weaken the enemy's bomber nuclear assault (the Navy actually proposed the same requirements as the US Navy in this era—— intercepting nuclear bombers).

And when the navy goes further in the future, it can also serve as the pillar of formation air defense, can conduct deep and precise strikes on enemy countries, and also has good anti-submarine capabilities (potential).

"Actually, I am looking forward to the early start of construction of the cruiser," Makino Shigeru said. "If there are omissions in the detailed design, we can make adjustments. We have considered the basic design of this ship very carefully, which means serious design problems. It's unlikely to be a problem."

Tang Hua said with a smile: "No matter how anxious you are, you have to wait for the launch of the Type 58 destroyer, and then make some technical improvements to the shipyard. The first Type 58 destroyer has not started yet."

Li Fuli: "It's coming soon, the keel will be laid in early March."

After successfully forecasting the weather four days ago with an accuracy rate of 63%, Ye Duzheng and Zhu Kezhen immediately packed their bags and rushed to Shanghai.

Of course, the calculation in Beijing is meaningful, just look at the accuracy rate, don't care too much about the time.If the supercomputer in Shanghai can calculate the data of the Huanghuai River Basin within 24 hours, then the China Meteorological Administration will be able to make medium and long-term weather forecasts with an accuracy rate of 15% for the weather in the Huanghuai region after 63 days. This is an earth-shattering event .

Tu Changwang had been in Shanghai all the time. When several people from the Meteorological Bureau gathered, the Tianhe-[-] test was still at the end.

"Heh, this room seems to have heating, and it's still burning hot." When Zhu Kezhen entered the door, he found that the temperature in the hall was very high. He took off his coat and coat, and only put on the sweater inside.

Tang Hua: "This is the result of the ventilation system working hard to remove excess heat."

Ye Duzheng: "The mainframe in Beijing is an electric tiger, and the power consumption of this supercomputer is only a little bit more. Let me see... well, there is a big difference between a supercomputer and a mainframe."

The four cabinet groups of Tianhe No. 10 are placed in the center of the hall. Each cabinet group has [-] cabinets arranged in a C shape, and the gaps are convenient for maintenance personnel to reach in.

In the center of the C-shape, there are dense connections between the cabinets. If you are not a designer or a computer maintenance worker, you will feel dizzy just by looking at it.This is the result of trying to simplify the appearance of the supercomputer during design. Not to mention anything else, the water-cooling pipelines and main pipelines of the 10 cabinets are all buried under the floor of the hall. in the cupboard.

Water cooling takes away most of the heat. Generally, the temperature of the computer motherboard will not exceed 60 degrees.However, the tens of thousands of chips at 50-60°C in the four groups and forty cabinets of Tianhe-[-] are enough to cause a heating effect in the hall.

Tang Hua: "In winter, the ambient temperature is only a few degrees, so the temperature performance was pretty good during the test. I don't think it will work in summer, and the temperature has to go up a bit. Wang Shoujue, add a high-power air conditioner to your computer station."

……

"Today, February 2, and tomorrow, February 24, I have asked the Meteorological Bureau to collect the data from tomorrow's observation stations and send them directly to Shanghai," Tu Changwang said, "based on the data from the 2th, we will deduce the mid- and long-term weather forecast. "

The weather forecast program uses the latest algorithm brought by Ye Duzheng from Beijing, but the program still needs to be modified—the operating system of the supercomputer is not compatible with the small/medium/large computer, and it can reach a calculation speed of 6.4 million operations per second. It relies on a special structure and a special command system.

At noon on February 2, data from the observation station of the Meteorological Bureau poured into the Shanghai Computer Institute like a tide.In the past two years, the National Meteorological Administration has built a large number of new meteorological observation stations, including 25 ground observation stations in the Huanghuai area, including 1100 high-tower observation stations, 200 high-altitude balloons, and 150 weather radar (Nanjing Radar For the manufactured prototype, the test site was directly set in Huaibei).

At 2:25 pm on February 3th, the meteorological data was unified and sorted out, and the new algorithm was just reflected in the program. The data observed at 8:[-] am on the same day were input in batches by more than ten programmers, and after the input, they had to be repeated Proofreading.

"It turns out that the image depicting the air mass was expanded with a data matrix?"

Tang Hua saw that Tu Changwang and the others were punctuating and drawing on the drawings when sorting out the meteorological data. It turns out that the current "cloud map" uses point data obtained from observation stations one by one to "brain-fill" the dividing line between high-pressure and low-pressure air masses. Graphically form the dot matrix.The plane shape, height, moving speed, temperature and humidity of different air masses are actually calculated.

Zhu Kezhen: "That's right. Based on the difference in the data of the two observation stations, it is necessary to determine where the dividing line is on the line connecting the two observation stations. The main parameter for judging is the air pressure, but the air pressure sometimes changes unevenly , but you have to combine terrain and wind speed, and intuition ... this is the family craft of meteorologists."

Tang Hua: (smiling)

In a few years, I may smash the family handicraft jobs of all of you here, heh heh.
