Chapter 822: German frigate design flaw: leaking chimney
The banquet lasted for four hours before it was over, but not everyone left together. Davidson lingered and stayed at the end.
"Davidson, we are old friends. I came here in a hurry this time and I didn't bring anything good. Once our Golden Sun electric car is mass-produced, I will give you one as a gift."
Davidson was overjoyed: "Really? Then I will become the most dazzling person in Africa."
Not only did they accept bribes, they were also aboveboard and did not think it was a shame at all. If Qin Tao gave him an electric car, it would definitely be the most eye-catching.
"Recently we are preparing for the automobile factory. Once the factory is built, we can start construction." Qin Tao said.
"Mr. Qin, in fact, I have always felt that it was a mistake for you not to come to participate in our warship bidding. If you came to participate, you would definitely get the order."
"Well, we have been too busy recently and have not taken care of it." Qin Tao also lamented, how could he forget about Rainbow Kingdom in the first place? Mainly because there have been too many things in the past one or two years.
Ever since he was noticed by the World Police, he has been busy. If it hadn't been for this invitation, he probably wouldn't have come.
"It's a pity, it's such a pity." Davidson shook his head: "But don't worry, we will definitely change the contract and produce one at the Glorious Years Shipyard. After all, if we change your order, we will have to pay Germany a sum.
The compensation is too uneconomical for us.”
"That's not necessarily the case."
Not necessarily? Davidson's eyes lit up.
"Mr. Qin, do you have any ideas?"
"After Germany received the order, did they give you a design drawing?"
"Yes, I gave you a detailed design drawing."
"Can you give me this design?"
To you? This is definitely a violation of the contract. Isn't it unfair for the referee to hand over the bidder's design drawings to another rival?
"Don't worry, I still look down on German designs. Our Mingzhou Group's designs are the most advanced. I'm just checking for you to see what's unreasonable about the frigates built by Germany. If serious flaws can be found,
If so, then you have reason to give up on this deal. Not only can the Germans not ask for compensation, but they will also have to spit out your deposit."
Davidson's eyes suddenly lit up, yes, why didn't he think of it? If there is no reason, the German contract cannot be terminated. What if there is a problem with the German design? The Germans will have nothing to say at that time.
Even if we go to the international court to litigate, we will still have the confidence!
"The blueprints are with the Navy. For only $50,000, I can get them from the person responsible for keeping the blueprints," Davidson said.
"Okay." Qin Tao quickly wrote a check for one hundred thousand!
The other money, of course, is for Davidson's benefits.
Watching Davidson leave in a hurry, Xu Zhengyang came over and said, "Mr. Qin, the problem has been solved. You should be safe here."
Qin Tao nodded: "Thank you very much to the people on the hidden front. Our Mingzhou Group will create a subsidy for them."
"We don't need this, right?"
"It's okay to give it directly to their families." Qin Tao said, "Let's go back to the warship and discuss the next exercise. It's really difficult to shoot missiles because of the high winds and waves, but we can't be embarrassed if something happens."
Liu Dashan was surprised: "Mr. Qin, you don't plan to live in the shipyard?"
"It's better to be on a warship, otherwise a bribed cook may make me die inexplicably." Qin Tao said: "Anyone may rebel in the face of huge temptation. It's better to be careful when going out."
"Yes." Liu Dashan nodded: "Mr. Qin, when I get the design drawings, I will send them to the warship for you."
"No need to send it away."
"No need?" Liu Dashan looked at Qin Tao in surprise, and then reacted: "You already know what's wrong with this warship?"
Of course Qin Tao knows, but if he points it out directly, there will be no basis for it and people will be suspicious. Moreover, in this way, he can also give an old friend a sum of extra money. Giving money is also a skill.
Qin Tao smiled: "All countries are developing stealth warships. However, some people pursue stealth too much and ignore other issues. Even the veteran Germans have no experience in designing stealth warships. It is normal to make some mistakes.
, I only looked at the design drawings they released to the public, and I knew there was a problem. By the way, find me a magazine with the design drawings of the Rainbow Nation warship."
Liu Dashan looked at Qin Tao with admiring eyes: "Mr. Qin, you are so awesome! Don't worry, I have the magazine here!"
On the warship, everyone was excited about the drill! What they looked forward to most was the drill.
Regardless of the weapons installed on a warship, they are all very expensive. If a missile is launched, a Santana will be wiped out. Many sailors have been in the navy for half their lives and have never fired a missile. Needless to say, missiles.
The multi-barreled rapid-fire cannon fired once and destroyed a small QQ.
Their No. 526 frigate has only fired live ammunition once since it was commissioned. Although their missile silos are half filled with missiles, they usually just watch and have no chance to launch. This time they can finally fire live ammunition.
How could they not be excited.
"Don't be too happy too early." Qin Tao looked at the excited officers: "The sea area here is different from ours, with high winds and rough waves. In this case, we must formulate a careful plan and come up with a
We are at our best, but if we fail, then I can’t afford to lose this person!”
"Mr. Qin, don't worry. Over the past few years, we have already become familiar with the equipment on the warships. It doesn't matter whether the wind is high or the waves are fast. No matter how low the drone flies, we can shoot it down. Just like this
Depending on the sea conditions, they fly close to the sea surface, and we can detect them from 20 kilometers away and kill them from 10 kilometers away!"
This chapter is not over yet, please click on the next page to continue reading the exciting content! Although the Hongqi-16 they are currently equipped with has a range of forty kilometers, it is for medium-altitude targets. For ultra-low-altitude targets flying over the sea, the range will be
Shrunk by half, but this is already very good. After all, the range of Rainbow Nation’s anti-aircraft missiles is only a dozen kilometers.
It is to show them our strongest strength and make the other party decide to directly purchase our complete sets of equipment. Even if they do not purchase, they still have to see the advanced technology of the East, and then abandon the German order and switch to the embrace of the East.
The international arms market is like this. Buying and selling are done by snatching.
Don’t be dissatisfied with the Germans. Their technology is not good and they can only blame themselves. Look at Europe, what do they have now? The air defense destroyers with four-sided phased array radars have not yet entered service. The dumplings have already begun to rain in the East. They have long been behind the times.
Well, in terms of air defense missiles, their strength is also very poor. They only have missiles with a range of tens of kilometers and have no regional air defense capability at all.
The Rainbow Nation Navy currently does not have large warships, so the only missile boats that can be sent to the exercise are missile boats.
The Rainbow Nation Navy currently has six Reshev-class missile boats. These missile boats come from Israel. In previous eras, the relationship between them was very friendly. When faced with external sanctions, only Israel maintained close relations with them.
Even the brand-new fighter planes planned to be developed by their air force were developed with the help of Israel. Of course, Israel's technology was insufficient, so a large number of technicians from Dassault were invited.
The Reshev-class missile speedboat has a displacement of only 450 tons. It is said that this speedboat should be very fast. However, due to various technical limitations, its top speed is only 32 knots, which is the same speed as a conventional warship. It makes it
The combat effectiveness is not high.
However, this is the main force of the Rainbow Nation Navy. Therefore, the Rainbow Nation Navy is eager to obtain brand-new warships. After several years of inspection, it finally placed an order with Germany.
During this exercise, the Rainbow Nation dispatched four missile speedboats, sailing on both sides of the frigate No. 526. The small boats guarded the warships, forming a unique formation.
On the bridge of No. 526, the Rainbow Nation Navy formed a six-person observation group. After all, too many people would be crowded, which was not conducive to the conduct of the exercise. The other naval officers who were not selected could only watch the warships from the surrounding missile boats.
Their eyes were full of expectation. In the future, they would also have such large warships.
In their eyes, a warship with a displacement of three to four thousand tons is already quite large.
"This warship sails very smoothly and can fully meet the needs of our navy." Long Wayne, the leader of the observation group, said, "Now, we are looking forward to the wonderful performance in the future."
Just now, five warships sailed together in formation, performed various maneuvers, and demonstrated their navigation capabilities. Next came the most critical anti-aircraft missile interception display.
"What we are launching this time is a target modified from the Gabriel anti-ship missile. The technology of this anti-ship missile is very advanced. I hope you are ready." Anderson said.
They have a total of six missile speedboats, one of which is under maintenance, and only five boats can participate. Four of them join the formation, and the other one is outside the formation, ready to launch anti-ship missile targets at any time. (There is also a saying that
Three ships.)
"We are ready. Without the help of any early warning aircraft, our warships alone can complete all the interception work." Qin Tao said: "Right now, our radar is searching for the target."
The reputation of the Gabriel anti-ship missile is not great, and it has no results. Many people do not even know the existence of this kind of anti-ship missile. Among Israel's huge military weapons and equipment, this one belongs to passers-by. However, if we say it If there is an imitation prototype, then everyone knows it: the Harpoon anti-ship missile.
This missile was developed by Israel on the basis of the Harpoon anti-ship missile. The initial mk1 and mk2 models were almost indistinguishable from the Harpoon. It was only in later models that big changes took place. The later mk5 even had With a range of two hundred kilometers, it stands out among Western anti-ship missiles.
Of course, what the Rainbow Nation has is an early model. After all, their missile speedboats do not have the ability to search for targets at long distances, which is only a range of thirty or forty kilometers.
At this moment, a radar officer reported: "Target found, distance fifty, speed thirty, nine o'clock direction!"
As soon as this report came out, everyone in the observation group was a little embarrassed. How could this be a sneak attack? The missile boat had not been launched yet, and the missile boat was found first.
If this were in a state of war, the missile boat would have been sunk, and it would have died before it was launched!
"Mr. Qin, isn't your air and sea search radar too advanced?"
"I heard that this kind of radar is an imitation of the big-haired radar. The big-haired radar is not that powerful."
"Everyone, the 382 radar is installed on the top of our warship and at the highest part of the mast. Its appearance is very similar to Lao Maozi's roof radar. The main reason is that the exposed identification friend or foe antenna is removed. However, its internal changes are quite significant. "Qin Tao said: "The performance of our radar is incomparable to Lao Maozi's roof radar."
Qin Tao opened his chatterbox and introduced everyone.
Lao Maozi uses the M-type radar. The maximum power of the radar is only 30 kilowatts. It can detect air targets with a horizontal distance of 130 kilometers, an altitude of 5 kilometers, and a radar cross-section area of 7 square meters, or a distance of 30 kilometers and a radar cross-section area of 500 square meters. A square meter ship can track twenty targets at the same time.
The ones exported to Asan are also of the same level.
Later, Lao Maozi went through a lot of improvements and launched the latest mae-5 radar. The transmission power was increased to 90 kilowatts, and the performance was greatly improved.
However, this is not as good as Dongfang. The maximum transmit power of Dongfang's radar has reached one hundred kilowatts. For radar, as long as the transmission system is determined, the next step is to look at the power. The greater the power, the farther it can see. .
This chapter is not over yet, please click on the next page to continue reading! Therefore, the maximum search distance of this domestically produced 382 radar exceeds 250 kilometers. The ejection distance for anti-ship missiles can also reach a distance of 35 to 50 kilometers. As for Missile speedboats? Of course they can be found at a distance of fifty kilometers.
In addition to the high power, the later data processing system is very powerful. Every time the antenna rotates, it can automatically track more than a hundred targets, and it can also accurately track the trajectories of twenty targets.
Now, the missile speedboat that came at high speed on the sea has been captured, which is equivalent to half the loss!
"Missiles ready for launch!"
Although the opponent has not yet launched the missile, the cover of the launch silo has been opened, waiting for a sharp attack at any time.
"The target is forty kilometers away!"
"The target is thirty kilometers away, and a target has been separated, with a speed of Mach 0.9!"
"The target has been locked!"
"launch missile!"
A column of smoke rose from the front of the ship and shot straight into the sky. The naval officers of the Rainbow Nation looked at the flight of the missile with envy, and then became curious: "Why haven't your missiles dived yet?"
Because it is launched vertically, the missile must first hit the sky. Facing a target flying over the sea at ultra-low altitude, it must still dive. But now, this missile flies into the sky and disappears?
"Our anti-aircraft missiles first fly at medium and high altitudes, and then dive down when they reach the target," Qin Tao said.
The firing range of the Hongqi-16 was increased from a dozen kilometers to forty kilometers using this method, without any changes, just correcting the ballistic trajectory.
"Aren't your missiles guided by semi-active radar?"
With semi-active guidance, the missile has to receive the radar waves reflected from the target at all times and must follow it. If the target flies at ultra-low altitude, it also has to fly at ultra-low altitude. Now, the missile actually flies at mid-to-high altitude first. This is unscientific.
"The final guidance is still semi-active, but the first half of the flight is based on inertia or radio commands, which can improve the ability to resist saturation attacks." Qin Tao introduced.
The multi-target interception capability of a semi-active radar depends on how many targets illuminate the radar, that is, the fire channel. What if there are too many targets?
After assigning a target to the missile, the missile can be launched. If there is no target to illuminate the radar? Wait, wait until the last one hits the target, the target illumination radar is free, and then illuminate the target it is aiming at.
"Your technology is too advanced!" the naval officers sighed.
The speed of the interceptor missile was very fast. After flying at a medium-high altitude of about twelve or three kilometers, it began to swoop down. The target had already flown seven or eight kilometers away, and the distance between the two sides was less than ten kilometers!
At this time, on the bridge, a specially hung display showed the trajectory of the missile and the trajectory of the target. The two sides were getting closer and closer.
Then, both signals disappear.
"The target has disappeared and was intercepted successfully!"
"That's great!" Longwayne said with emotion: "Under this sea state and under these conditions, your radar equipment detected in advance and your missile system accurately intercepted it, which reflects your superb technical level!
"
Everyone else applauded.
"So-so." Qin Tao said with rare humility: "Actually, we have also made preparations. If the interception fails, we can still conduct a second interception. If the second interception also fails, we can still use
Close range defense artillery.”
This is not modesty, it is telling the other party that we have secondary interception capabilities and three interception capabilities of close-in defense artillery!
"President Qin, your warships are so advanced, it's an eye-opener for us!"
"I just don't know which one is more advanced, your warship or the A200 frigate we ordered." Anderson also sighed with emotion.
"Well, I have something to say, I don't know whether I should say it or not."
"Speaking."
"This morning, before leaving the port, I found a magazine with an introduction to your order of frigates from Germany. There was a design drawing in it. I think there is something wrong with this design drawing." Qin Tao said: "Of course, your navy
It must have gone through some review, and now there is a problem, which may embarrass some people who participated in the review."
"Mr. Qin, do you see the problem?" Longwayne became serious: "Then you have to point it out to us! Yes, we have passed the review, but we have no experience with stealth frigates, even if it is
If there is a problem, it is not the responsibility of our reviewers. This is the tuition fee that should be paid. Mr. Qin, please give me some advice."
In front of everyone, Qin Tao took out an issue of Jane's Defense Weekly. There was indeed a design drawing of the Meko A200 frigate ordered by the Rainbow Nation from Germany. It was just a simple structural diagram for military fans. However, Qin Tao
Tao saw the problem from above!
Davidson is a government employee, but not a naval officer, so he is not qualified to come up. However, when he goes back, this matter will definitely spread to everyone's ears.
"In order to reduce the infrared effect caused by the exhaust gas emitted by the power system, modern warships generally deal with the exhaust system." Qin Tao introduced: "The main method is to pass seawater to let the seawater cool the exhaust system.
Ordinarily, the Germans have been building warships for decades, so they should be very familiar with this kind of operation, and there will be no problems. However, I found that the Germans are still lacking in the development of stealth warships. When this chimney is combined with the stealth shape, it appears
A serious problem."
"what is the problem?"
"Water intrusion." Qin Tao said: "Water can enter the main engine through the exhaust cooling system. You are all sensible people. Do you know what will happen if water intrudes into the engine?"
There is no chance to drive a warship, but there is also a chance to drive a car. Once the car stalls in the water, it must not be re-ignited, otherwise the water will enter the cylinder and cannot be compressed, and the piston and crankshaft will all bend, and the engine will need to be overhauled.
And the engine after overhaul cannot reach its original level.
Of course Qin Tao remembered that in his own time and space, the Rainbow Nation Navy happily received the Valiant-class frigate and returned to its own waters for testing. After a few trips to sea, well, the engine got flooded.
The Germans proposed repairs, but the Navy of the Rainbow Nation refused to do it. The new warship I bought has not been officially commissioned yet, so you want to repair the engine for me? It’s already good if I don’t let you refund one and pay three!
Qin Tao knew about this fault, so he took out the design drawing from the magazine and explained it to everyone.
The faces of these people were all darkened.
The cooling system of the exhaust pipe is leaking and will it enter the engine? This is a big problem! Isn’t Germany striving for excellence? Isn’t it the world’s number one craftsmanship? Why does this kind of problem still occur?
"Mr. Qin, thank you for your advice. We will find experts to analyze and see if there is any problem with this design." Davidson said, "Excuse me, are there any other questions?"
"I don't know about the other ones. After all, I don't have detailed design drawings, and some of them are not reflected in the design stage. Only after they are produced, will I find some terrible problems."
In addition to the problem of the exhaust pipe, another big problem of these warships is the construction of the cables: the moisture-proof treatment is not in place! So after using it for a period of time, the cables became damp, and various problems began to occur. The Germans solved it
The plan is to replace those cables that are affected by moisture, but Rainbow Nation wants to replace them all. Who knows if there are any problems with the others? However, for a warship, replacing all the cables is definitely a big project!
However, this issue cannot be discussed now.
"Isn't Germany a veteran? How could they have such a problem?" Some people are also curious.
"Well, what's wrong with the old companies? Have they ever built a stealth ship? What is the tonnage of surface ships they have built in the past ten years? The old companies may not be able to adapt to the new era."
