The new 052-class frigate, which has installed two groups of four NJRQ1980A-type gas turbine units, is undoubtedly much stronger than the power output of the 4× SEMT-Pielstick-12-PA6-V-280STC diesel engine unit used in the original Lafayette class.

After using TQYH78 easy-to-weld high-strength low-alloy ship steel produced by Baotou Steel as the main structural material of the hull, the standard displacement of the new 052-class frigate is only 3,120 tons, and the full load displacement is 3,500 tons.

Yang Weiping silently compared the new 052-class frigate in front of him with several main parameters of the Lafayette-class frigate he was familiar with in his mind, and was more and more full of expectations for tomorrow's launching sea trials.

Seeing the gratifying smile on Director Yang's face, Li Fuli introduced more vigorously, "Director Yang, according to your original noise reduction design requirements, we specially designed an elastic base for the new 052-level host that can absorb vibration and noise. In addition, a bubble curtain manufacturing system has been installed at the bottom of the ship to minimize the noise of the hull and power system when sailing. In addition, the tip of the variable pitch propeller releases air bubbles to avoid cavitation effects. As a result of these measures, the new 052-class has an excellent level of quietness, exceeding the U.S. Navy standard. ”

"How did you deal with the infrared reduction?" Yang Weiping asked with a satisfied nod.

Li Fuli replied without thinking about it: "We have designed a new exhaust system, which can make the exhaust gas of the new 052 main engine mix with the outside cold air through the heat exchange system and cool down before discharge. The shape of the chimney has also been optimised. Reinforced glass fiber, which is less prone to infrared signals, and a special heat-insulating coating is used. In addition, we have developed a special coil to counteract the reflection of the magnetic signal from the hull. ”

Yang Weiping looked at Chief Engineer Li Fuli deeply and secretly praised him in his heart. He only put forward technical requirements and some research ideas on the design drawings, but Chief Engineer Li and the project team led by him used their creativity to come up with specific and effective solutions.

As the first ocean-going treasure of the Chinese Navy, the 051-class missile destroyer designed by Li Fuli can be said to be a milestone in the development history of the Chinese Navy.

At that time, when China designed its first destroyer on its own, Western countries already had a history of destroyer research and development for more than 60 years. For Xinhuaxia, which has never had any experience in building large ships, the best way to mitigate the risk is to copy the mature skills of others.

When Sino-Soviet relations broke down, some of the technical drawings of the Type 56 Kotlin-class destroyers of the Soviet Navy were left in China. These technical materials and the design drawings of four old World War II-era Rage-class destroyers that the Soviet Union resold to our country. It became the only reference basis for Huaxia to design the 051-class destroyer at that time.

A warship is a huge project. The drawings alone would have to be full of truckloads. Li Fuli: At that time, they only had paper, pens and iron rulers. If the large engineering drawings and complex engineering line drawings are all drawn by manual strokes. Without a computer, you can only use an abacus to calculate.

The best thing about the 051 design. It is that the ship successfully solved the problem of the overall layout. It is the most compact and beautiful destroyer in the Chinese Navy. It has good seaworthiness. There is a lot of room for upgrading, and until the twenty-first century, destroyers of this type are still working diligently on the front line. You can still sail to all parts of the world. And the Soviet Kotlin class, which was close to its blood, all returned to their hometowns as early as the twentieth century and the eighties.

Although the 051-class missile destroyer is still far from the advanced level of the world, it has solved the problem of starting from scratch for the Chinese Navy!

It is precisely because the team led by Chief Engineer Li Fuli has the foundation for the design and development of the 051 class from scratch to its success, and after absorbing the modern advanced ship manufacturing and design technology and experience of Germany and Britain, the birth of the new 052 class missile frigate has been born.

"Director Yang, Director Yang, is there anything wrong?" Li Fuli saw that Yang Weiping's eyes were a little trance-like, and asked nervously and softly.

"Hehe, it's nothing, I just remembered the difficult process of Chief Engineer Li when you designed the 051-class missile destroyer. Yang Weiping shook his head truthfully and smiled: "We now have a new 052-class frigate, and we have to design a stronger and more advanced new 052-class destroyer and cruiser!"

"Director Yang, this is a must!" Li Fuli nodded vigorously with an extremely firm look in his eyes, "The Huaxia Navy has been waiting for this day for too long. Our current conditions are more than 108,000 miles stronger than they were in those years! After the advanced new type of ship special steel and gas turbine have achieved self-sufficiency, the two biggest roadblocks that stand in the way of the advance of our Chinese blue-water navy no longer exist! Director Yang, we Chinese shipbuilders are confident that we will design and manufacture first-class frigates, destroyers, and cruisers in the world!

"I am very convinced of this!" Yang Weiping nodded with a smile of approval and said: "Chief Engineer Li, when you designed the 051-class destroyer, you focused on the issue of seaworthiness, I think, you should have a better solution for the new 052-class frigate, right?"

"Yes! Director Yang. Li Fuli nodded and said: "The new 052 class has a very strong continuous self-sustaining independent operation performance. It can store 80 cubic meters of helicopter fuel and support six months of helicopter spare parts stock, and store 60 tons of fresh water, and the ship's fresh water machine can produce 36 tons of fresh water per day.

According to your design requirements, the new 052 class also pays special attention to the living conditions of the officers and men on the ship, as well as the arrangement of living space, so as to avoid the decline in combat effectiveness and morale of the officers and men on the ship when they are operating at sea for a long time. The NJRQ1980A gas turbine combined with the power generator set drives two variable pitch propellers and the maximum speed is controlled at 30 knots, although some of the high-speed performance is sacrificed, but the new 052 class has excellent economic endurance performance. 15 knots can sail 7,500 nautical miles, and 12 knots can reach 9,600 nautical miles!"

Listening to the data reported by Li Fuli, Yang Weiping couldn't help but compare it with the Lafayette-class frigate, and found that the new 052-class frigate had significantly improved in terms of maximum speed and sea-holding performance.

"It seems that our new 052 class has reached the world's first-class level in terms of sailing performance. Yang Weiping nodded with satisfaction and said with a smile: "The navigation performance has been solved, but the stability of the warship and the management of the war damage are the top priorities." ”

"Director Yang, let it go, stability and anti-war damage management design, the new 052 level will not disappoint you either. Li Fuli replied with a confident smile: "In terms of stability, we designed a pair of stabilizing fins on both sides of the hull of the new 052 class, which are controlled by the ship's computer together with the rudder to reduce the roll and pitch of the hull, so that the new 052 class can carry out helicopter take-off and landing operations in the sea state of level 6."

In terms of resistance to damage, hull resistance, and damage management capabilities, the new 052 class has a series of new achievements. In terms of hull strengthening, the superstructure of the new 052 class adopts a sturdy airtight barrier design, the hull below the waterline adopts a double-hull design, and important parts of the hull are reinforced with new armor steel. There are three watertight compartments between the front and rear main engine compartments to isolate fire or water ingress.

In addition, according to your fire protection requirements, we do not use the flammable and fusible aluminum alloy material that is commonly used in superstructure applications on ships, the front superstructure is made of high-strength and high-temperature resistant nickel alloy steel, and the final hangar structure is made of new aviation resin-based materials that are light and resistant to high temperatures.

In terms of damage management, the ship is divided into three damage management areas, each with its own automatic damage management monitoring station and independent fire control facilities, and there are fire curtains on the main passage to prevent the spread of thick smoke and fire. Fixed or mobile fire extinguishing, pumping and ventilation equipment are generally installed throughout the ship.

Important cabins such as ammunition depots and engine rooms are equipped with automatic sensors that can detect fire, smoke, temperature, and water ingress. The shipboard damage management center of the new 052 class is a computer damage management system that can be centrally controlled newly developed by the computer research department of the Marine Installation Institute. The system can manage the ship's damage management information in a unified manner and command and dispatch the damage management operation, which greatly increases the survival rate in the event of battle damage. The system also has universal connection ports with various parts of the ship, so that damage management personnel can connect with the damage management center through small computers at any location on the ship to obtain the latest damage management information. ”

"Very good!" Yang Weiping nodded and praised: "One of the most important signs of a modern navy is the comprehensive application capability of computers on ships. The fact that Haizhuang was able to independently develop this set of damage management system software fully shows that the naval equipment research department has used its brains in the application of computers! We just want to carry forward this spirit and style of being able to solve problems independently without waiting or relying on them!

The Air Force has achieved world-class results in avionics, and I hope that the Navy will also make a breakthrough in the electronic control of ships. I once told the computer research department of the Haizhuang Institute to cooperate with the Computer Center of the Chinese Academy of Social Sciences to develop the 'China Shield" warship command and control system.

"Director Yang, the set of 'China Shield' you put forward is too demanding in all aspects. Li Fuli shook his head with a wry smile and said: "It is not difficult to integrate fire control, radar, sonar, communications, and damage management into one system software for comprehensive management. ”

"Just because you can't do it now doesn't mean you won't do it in the future. Yang Weiping said: "Today's computer technology will be updated every 18 months! The performance of chips will become stronger and stronger, and the storage capacity of hardware, such as memory and hard disks, will also become larger and larger. The 'China Shield' system is the future development direction of the Chinese Blue Water Navy, and the earlier we start and the more we invest, the more we will be able to walk in the forefront of the world in the future!"
