Chapter 1072 The Rhythm of Dumplings (Third update, please subscribe)
No one knows the navy better than me!
At least to a certain extent, it is true that no one understands the modern navy better than Li Yian.
There is no other reason, because he does stand on the shoulders of historical giants!
What era is it now? The 1950s. It is the era of replacement of old and new warships. It is the era of missiles replacing artillery and moving towards guided missile warships. At the beginning of this era of change, the navy has too many attempts.
Therefore, Li Yian, who stands on the shoulders of historical giants, can directly skip those eliminated attempts.
"Build a new type of guided missile destroyer."
At this time, Cheng Zhiyuan didn't say much, but he just spoke to Li Yi'an's heart. Guided missile destroyers are undoubtedly the real future. Not only that, but his "experience" in "Xia Dumplings" is far greater than others. For example, in Xia Dumplings, the US Navy made a mistake - nuclear power cannibalized the Navy's already small budget, directly It affected the scale of the U.S. Navy's "dumplings", so much so that until the late 1970s, there were still many auxiliary ships with equipment from the World War II era. Yes, there were times when landlords had no surplus food.
In contrast, Tangshan’s strategy in the new century was much more rational and cautious—continuously building a large number of destroyers. When the destroyer fleet and auxiliary ships grew to a certain extent, adding aircraft carriers would be complete. aircraft carrier battle group.
“The Naval Technology Department developed a miniaturized twin tilt launcher based on the American MK10 twin tilt launcher. It launches the Tianjian 2 anti-aircraft missile. This missile is already very mature. , with a range of up to 60 kilometers, which can provide regional air defense for the fleet. ”
Listening to Cheng Zhiyuan's introduction, Li Yi'an's mind came to mind that he had seen the Navy's anti-aircraft missile target practice. From the perspective of future generations, the twin tilt launchers must be backward, but this is the limitation of the times.
As we all know, vertical launch is the real future.
Listening to Cheng Zhiyuan’s introduction, Li Yian thought for a while and said.
“At present, the use of launchers can meet the demand. However, from the perspective of development direction, I think the launch method of anti-aircraft missiles should be vertical launch.”
“ Vertical launch? ”
Zou Tongjie, who was grieving over the postponement of his dream of a nuclear-powered aircraft carrier, also became curious.
"Yes, it is vertical launch."
Li Yian picked up the pen and drew a sketch on the note while saying,
"Compared with the traditional tilt launch system, The vertical launch system has many advantages. First, the response time of the vertical launch system is short. The storage state of the vertical launch ship-borne missile is the launch state. The missile is placed vertically in the launch silo in a ready-to-launch state. It can be launched immediately after receiving the order. Turn to the direction of the target like a tilt launch."
What does it mean to stand on the shoulders of giants?
This is standing on the shoulders of giants. In this era, absolutely no one understands the evolution of warship air defense systems better than Li Yian. The evolution of post-war missile launchers is a complicated and tangled process. The most intuitive manifestation is: missiles From horizontal to vertical, and finally evolved into vertical launch.
In the end, systems such as shipboard vertical launchers and multifunctional phased radars were combined to form the so-called "Aegis System", which ultimately led the world's navies to develop in this direction!
What Li Yian is doing now is to help Nanyang reduce the cost of trial and error.
“Missiles launched at an angle will form a launch blind zone because part of the launch area is affected by the superstructure of the ship. With vertical launch, the missile rises to a certain height after launch and is controlled by command to turn to the target direction, which can effectively eliminate The blind zone of the superstructure enables 360-degree all-round launch.”
“In addition, the vertical launch system can easily implement a standardized structure, and can configure anti-ship, anti-submarine, and anti-aircraft missiles with roughly the same appearance and size in one fire unit. , to deal with different targets respectively, and the vertical hair system eliminates many complex motion and control components, the structure is relatively simple, and the reliability is greatly improved.”
Although he knew that it was obviously unrealistic to produce "Aegis" with the current technical conditions, Li Yian just pointed out a direction. After all, with a general direction, at least a lot of trial and error time and costs can be saved.
Listening to your explanation, Navy generals Zou Tongjie and Lin Zhiyuan immediately understood the advantages of the vertical launch system. Just as they were considering communicating with the naval technical force immediately to develop a similar launch system system, Li Yian turned his attention to the construction of warships.
“In addition, when designing warships, we must not only consider our own needs, but also the foreign trade market.”
For those who are dedicated to making Nanyang’s arms trade bigger and stronger For Li Yian, the warship trade is definitely a big deal. To put it more expensively, one warship costs hundreds of millions!
“And how can we get a share of the saturated overseas military trade market? This is a question we must consider.”
Li Yian frowned and said.
“In addition to the impact of a large number of retired warships, we also have to face strong competitors such as the United States and the United Kingdom in the market. Therefore, we must choose a cost leadership strategy. My idea is to adopt modular shipbuilding Concept - splitting a warship from a single system into multiple modules such as hull, power, and equipment. "
In another world, this modular shipbuilding concept was an invention of the German shipbuilding industry, which not only made them successful. It has entered the international warship market and created a new concept. "Compared with traditional shipbuilding, the "spelled out" warship has many advantages - cost savings. Compared with traditional shipbuilding, multiple modules can be started at the same time, and the construction cost is also reduced. Maintenance is easy, and when a certain part of the ship When a module fails, as long as it is not a serious failure involving the hull or power system, the faulty module only needs to be removed for repair, and the maintenance time is greatly shortened. . If the customer is temporarily unable to purchase certain equipment due to financial constraints, he only needs to retain the matching installation grooves, and the new equipment can be put on the ship in a few days when financial conditions permit..."
After a pause, Li Yian smiled.
“It is also convenient for us to improve and upgrade. For example, at the beginning, we can use an inclined launcher. After the vertical launch system is successfully developed, it can be directly replaced. The same is true for the radar system.”
The seemingly simple explanation had an unimaginable impact on Zou Tongjie and Lin Zhiyuan. They had never thought that warships could be built in this way. This simply overturned the concepts they had formed long ago.
At this moment, Li Yian explained again.
“Of course, these are just concepts. You don’t have to be greedy for everything at once. You can do some research in this area first. As for the construction of destroyers, you can do it step by step.”
Speaking of this, Li Yian emphasized again.
"If there is no suitable gas turbine, you can use a steam turbine. After all, this is used all over the world now. You can consider similar products from the UK. We always need to make some purchases to maintain the trade balance between us."
What is the biggest problem as a foreign trade country?
Not only selling goods, buying goods is also extremely important. If you blindly pursue trade surplus, it will inevitably break the balance, and this will most likely lead to trade disputes. In essence, all trade disputes All because the "trade balance" has been broken.
To put it further, one of the main reasons for the ban on smoking in the Qing Dynasty was because of the outflow of silver. After the failure of the ban on smoking, the anti-smoking faction simply said, "I despise planting poppies in the mainland, and it will not hurt the problem. Those who hate it, the mainland The Chinese people like foreign cigarettes rather than local cigarettes." And smoking foreign cigarettes costs money to import, and the silver will flow out.
Even the Manchu Qing Dynasty, which was closed to the outside world, knew that the trade balance was broken and had to take measures to check and balance. What's more, countries such as the United Kingdom and the United States, which relied on trade, have always maintained a trade balance as much as possible when developing their foreign economies.
Just like the power system of imported warships now, it is a way to maintain trade balance.
"Your Excellency, this may be difficult."
Zou Tongjie had completely come out now and said with some embarrassment.
“In the past few years, we have been cooperating with BMW to promote the development of marine gas turbines. At the end of last year, BMW also launched the M25 gas turbine based on the WP100-4 turbofan engine. The turbine engine not only has stable performance and advanced structure, but also has an overhaul time of up to 5,000 hours. BMW is still conducting research to improve its lifespan. It is expected that the overhaul time will reach 10,000 hours in the future. The most important thing is The power is also very powerful. The current model has reached 25,000 horsepower. As a warship power, its advantage is very obvious, that is, the energy density is extremely high. At the same power, the volume and weight are only 1/3 to 1/5 of the diesel engine, or even less. It is 1/10 that of a steam turbine, and has fast acceleration and quick start. It is especially suitable for use as the main power of large and medium-sized surface ships! Therefore, the Navy has already determined it as the main power.”
In other words - it is impossible not to use an advanced gas turbine engine but to use a steam turbine that requires dozens of hours of boiling water to reach full power!
Zou Tongjie’s answer made Li Yian shrug his shoulders helplessly and said.
"In this case, there is no other way. I originally wanted to take care of the British business."
In fact, the source of Nanyang's gas turbine engine technology is the British. Not only did the British It developed a gas turbine engine in the late 1940s, and built the 5,300-horsepower complex cycle gas turbine RM60 as early as three years ago.
As early as the 1950s, Nanyang began to cooperate with British companies in this area, benefiting from Britain's deep foundation in this field, coupled with the Nanyang Navy's emphasis on this technology, and the BMW company Advanced turbofan engine technology has allowed Nanyang to catch up and become the leader in ship-based gas turbines. Due to its excellent performance, the Navy has determined the basic strategy that all large and medium-sized surface ships will use gas turbines as standard power.
But now, Li Yian doesn't know whether the disciples of the church have starved to death, but Nanyang's gas turbine engine has become Blue Star's No. Thanks to Li Yian's path guidance, this is also the biggest mistake Li Yian made.
Facing the navy who was about to start serving dumplings, Li Yian thought for a moment and then said.
"In terms of warship construction, our experience is still very lacking. I personally still have some ideas..."
