"Forget it... Bismarck, you should go find Zeppelin and ask her to ask the Air Force..."
Covering his forehead and waving his hands, Lütjens said that he was very tired and decided to let his own ship cat run errands.
Bismarck had a good relationship with Zeppelin, and she was a girl that everyone loved. It would be more effective than for someone like me to step out on my own. Even if I wore a naval uniform, I would not be ignored.
In fact, if Zeppelin was here, he would help run the trip, but Zeppelin might not have much time these days...
The most talked-about topic in the Third Reich's media and public opinion these days is the news of the Kiel Air Battle.
Twelve hundred heavy bombers launched an air raid on Kiel Harbor, but the spy was uncovered by Prince Eugen, who was restless because he had imprisoned too many people before and whose ears were pointier than a rabbit's. As a result, the positions of the beacon and the ground arson signal were shifted in the hands of the crazy hamster who was using electronic jammers, and then some fun-filled things happened.
There were four waves of bombers, each with a bombing width of ten kilometers. Although their momentum was so overwhelming, they all flew off course! Almost all the bombs were dropped on the outskirts of the exit of Kiel Fjord, leaving Kiel City and the naval shipyard unscathed. Moreover, before and after the air raid, a certain early warning command fighter directed the night combat interception and pursuit of GR-186 and NJG-2, as well as the double attack of a large number of anti-aircraft guns specially dispatched by Goering, who loved his daughter dearly. Even though there were a small number of newly equipped Mosquito fighters escorting them, the 1200 heavy bombers still suffered heavy losses!
Even without counting the planes that were so badly damaged that they were not shot down on the spot, the photos of 110 shattered heavy bombers dragging smoke and flames across the night sky above the port of Kiel and falling to the ground and being smashed to pieces in four waves of air raids throughout the night made a big news on the front page of the National Socialist Party newspaper "People's Observer"! When these planes dropped their bombs and turned around to retreat over the North Sea, they were intercepted by BF-88 and JU-G (night fighter) that took off from the Dutch airport, and killed these arsonists who were so enthusiastic about killing civilians in Berlin a week ago, and they vented their anger for the burning of the capital!
After a night of brutal air combat, all 47 squadrons of the Royal Air Force heavy bomber force that Admiral Harris had put together with all his strength suffered heavy losses. The aircraft that crashed and died on the spot in the air combat, plus the aircraft that were too badly damaged to return alive, lost as many as 61 aircraft! There were as many as 93 seriously damaged aircraft that needed to be returned to the factory for overhaul or even scrapped! Even among the remaining aircraft, half of them were seriously injured and needed some repairs before they could fight again - according to the unanimous estimate of the German Air Force, after this heavy blow, Harris' heavy bombers would have to be quiet for at least a month!
The most exciting thing is that among these planes, there are six Mosquito fighters that have just been put into service by the Royal Air Force of the United Kingdom. They claim to be wooden miracles because of their super high speed. In addition, a centimeter-wave terrain tracking radar was later found in the wreckage of a Mosquito fighter. This is nothing short of a pleasant surprise for the Germans.
The amazing pilot code-named "Edelweiss" who shot down these six Mosquito fighters also raised his record to 352 after this battle. This record is unprecedented and there is a great possibility that it will never be surpassed. After all, with the development of technology, in the future, a fighter jet that shoots down five planes can be considered an ace.
Goering, who was in a good mood and loved his daughter dearly, not only sent a telegram to commend the meritorious officials, but also got excited and just wrote a stroke of the pen to award an aircraft carrier an unprecedented Diamond Knight's Medal.
Later, when going out to sea, the medal was hung openly in the most conspicuous place in the conference room of the Zeppelin, leaving the pilots and crew on the Zeppelin stunned.
Imagine an aircraft carrier with medals hanging on it?
Of course, this was probably interpreted by Goebbels as a collective commendation.
(War-weary: Oh, oh, oh… Cunningham, you bad guy! I have worked hard and made great contributions, why didn’t the Royal Navy give medals to the warships… Oh, oh, oh…
Bismarck: Kill one crying monster with one punch! )
After the great victory in the Kiel air battle, taking advantage of the fact that the British would not be able to send heavy bombers for at least a month, the German Navy's Bismarck battleship, Tirpitz battleship, Zeppelin aircraft carrier and Prinz Eugen heavy cruiser could finally rest in peace in the naval shipyard - although, in fact, there was only one large dock in the Kiel Naval Shipyard that was 380 meters long and 80 meters wide, but the internal structure of the hull was severely damaged, and the upper deck needed to be modified, so only the Zeppelin was actually.
After taking a bath, a long-awaited good news finally came, that is, Bismarck and Tirpitz are finally going to change their guns! The small 380 water pipe can no longer meet the growing combat needs of the two sisters, they need a big root!
Just to install the heavier SKC34/406 guns, the turret ring extends to the dome and the bottom structure. In addition to widening, the parts below the dome of the battleship also need large-scale modification and reinforcement. However, at least in the early stage of the demolition of the project, the cat and mouse sisters do not need to enter the dock. When the construction of the Zeppelin is completed, with the size of this large dock, the two sisters can be pushed into the dock together by tugboat.
(Tizi: Ahhhhh, I can finally sleep together with my sister v (≧≦) m~~~)
(Cat: What are you doing? Stop pushing!...Ti!l!bits!ψ(╰_╯))
However, in this case, except for Bontai who was hospitalized and accompanied by his family, the members of the fleet who finally had some free time could all go to Berlin to grab their commander for free food and drink. Especially Lindemann and Top were the type who could feed the whole family if one person was full, so they flew to Berlin without any worries and brought their own burdens.
However, several people had no place to live in Berlin, and they did not have a place to allocate housing like General Lütjens did. In the end, they could only come to their boss pitifully.
When Bismarck opened the door early in the morning, he saw two people with suitcases standing at the door of the office.
The final result was that Lütjens found that his originally spacious admiral's office was now crammed with six camp beds. The degree of crowding even made Lütjens a little absent-minded, and he also recalled the warm feeling of squeezing into a hammock with a bunch of "brothers" in the large cabin of the training ship when he was a trainee at the naval academy thirty years ago.
"So, now you all come to my place to eat and drink for free, and even live in a dormitory, right?"
As a certain homeless admiral roared, he unconsciously put on the kind of tearful and frustrated "face" that was unique to the innocent school days when they joked with each other.
As soon as they saw this, they knew that Lütjens was joking.
Bismarck continued to fight for Zeppelin's diamond medal without any concern. Top scratched his head when he saw Lütjens's expression. Bei Zhai sat in the corner in a daze as usual, thinking about something. Eugen was timid and didn't understand the boys' routine, so he shrank behind Top in fear. The remaining Lindemann was embarrassed, grinning, showing off his big front teeth that were as bright as Li Yunlong (the hippie version).
"Commander, we are all homeless too. You can't just abandon us so heartlessly..."
"Get lost!"
Lütjens glared, opened his mouth, pointed his finger, and said, "Get out! If you can't pay the rent, I won't have you as my subordinate anymore." He said, "You can live here, but pay the rent first! If you can't pay the rent, all of you will come with me to run projects and do scientific research! Do you understand?!"
"I know, I know. We all came here to help."
Lindemann continued to smile, but there was a hint of seriousness in his eyes. Top in the back said nothing, but nodded silently. Even the electronics geek in the corner, Dai Mao, moved slightly.
"Yes, yes, we are here to help." Bei Zhai nodded quickly.
"I'm not helping you. You're here to eat!" Bismarck slapped the Diamond Knight Medal on Bei Zhai's head.
"You guys..."
Lütjens was stunned at first, then he snorted unconsciously and raised the corners of his mouth.
Just think about it, with two more errand boys, plus a homely girl who specializes in electronic warfare and is also good at drawing, and the "biological daughter" of the Air Force Commander going to get some engine information, the research work should finally be able to get on the right track, right?
As for the four ships waiting to be repaired at the Kiel Shipyard, let the girls take turns to run around and take a look.
Just like that, the days passed by little by little in the temporary blandness...
PS: Speaking of which, the Kiel Naval Shipyard is really not very large...
Chapter 745: Dr. Strange Cat's Research Group
"Well, it's settled then! Happy cooperation!"
"Happy cooperation!"
Along with the sound of signing on the contract paper, a fat hand and a weathered hand clasped together tightly, accompanied by applause from the surroundings - of course, this type of agreement definitely has no spotlight. After all, what was signed this time was a comprehensive cooperation agreement (top secret) for the German Navy, the German Air Force, and even the Kaiser Wilhelm Institute to jointly develop the "DaoDaN" weapon...
Looking at the scene where their captain on the stage and the "parents" of the Zeppelin family opposite shook hands and chatted happily, Bismarck and Zeppelin, who had worked hard to promote the consensus during the negotiation of this agreement, looked at each other and smiled.
In fact, the German Air Force and even Goering himself attached great importance to missiles and rocket weapons. Whether it was for supersonic research or pre-research for combat, the German Air Force Armaments Bureau had no shortage of technical data and research funds! With these things, and the use of the German Air Force Armaments Bureau's accumulation and connections in the aviation field, air defense missiles, anti-ship missiles, and even cruise missiles and air-to-air missiles have all begun to unconsciously YY in Bismarck's cat head...
As for Goering, on the one hand, he trusted Zeppelin's ability, and on the other hand, as early as the Gibraltar Raid, Goering confirmed that these ship girls did have a certain "brain hole" ability. Especially the two artifacts of electronic interference and magnetron, which made the progress of the German Air Force and radar no worse than that of the British across the Channel! As for these inexplicably difficult-to-pronounce "DaoDan", they were directly copied and used on the battlefield, and they were highly praised-even as soon as they returned to China, Lütjens and his team came up with a missile development idea that looked very feasible. And when this idea was discussed at a meeting of the German government's top leaders, he and Raeder, who had always been at odds, had nothing to say about this research and development plan.
Bismarck: Hehe~ After all, it’s the imagination of us later generations.
Although this thing can be used probably because of the ship girl, but there is an idea, and after all, Lütjens is at least the director of scientific research of the Kaiser Wilhelm Society and a person in the navy who is clearly inclined towards the Air Force - Zeppelin is simply an Air Force man - there are people in charge of it, and it seems that it can really do something, which is better than anything else.
Although Raeder always had some grumbles about this, after Lütjens repeatedly promised, "As long as we cooperate with the Air Force's rocket project team, I can thoroughly improve the oxygen torpedo technology I got from Japan! The Japanese cannot guarantee the safety of fuel and pure oxygen combustion, but this is the most basic skill in the hands of several rocket research groups on the Air Force side. What's more, the design of anti-ship missiles can also be accelerated by cooperating with the Air Force...", he finally turned around with a bitter face and waved his hand, agreeing to the commitment to project cooperation.
With the creative plan and matchmaking of the construction women, and the happiness of the navy and air force, the German missile program began to get on the right track...
Although, many of the ideas are actually from a cat.
(Does this count as Dr. Strange Cat? 2333~~)
For Bismarck, who came later and saw a lot, the body of the anti-ship missile was the easiest to study.
As the power of the V1 missile, the As-500 series pulse engine has a thrust of 014 kg and consists of almost only one pipe, one intake valve, and a set of fuel injection nets. Although it has problems such as high fuel consumption, low upper limit of flight speed (the upper limit can only reach 860 kilometers), large size (exceeding the length limit), large vibration of pulse explosion, and extremely short engine life (originally disposable), for cruise missiles, this simple engine can be said to be extremely suitable!
Then the remaining thing was to modify the V1 missile's body and engine, which were separated and had an aerodynamic shape that looked very immature at first glance. This was not difficult for a cat that came from the future and, thanks to the tyranny of a certain superpower, could see the American BGM-109 Tomahawk cruise missiles and stealth aircraft on TV every other day!
Although the As-014 pulse engine must be exposed to the air in order to cool the barrel of the combustion chamber, Bismarck has a much smarter idea than directly separating the missile body and the engine: a large air intake duct with a boundary layer isolation plate is opened on the belly of the missile behind the warhead, and the pulse engine is directly "sheathed" inside. In this way, not only can the air intake of the engine be guaranteed, but the "sheathing sandwich" outside the engine tube also has air pressed in from the air intake duct to cool the engine.
Although the engine performance of this era was insufficient, the shorter the intake duct, the better (the shorter the intake duct, the smaller the total pressure loss), and the slightly curved intake duct also had some impact on the intake efficiency. However, such a problem was not too difficult to solve for Bismarck, who was a battleship and could intuitively experience fluid mechanics on a daily basis, and Zeppelin, who was a fighter pilot and was also familiar with aerodynamics, with the help of a group of aerodynamic experts:
Since the As-014 engine is so long, the air intake and the engine in the casing are directly placed under the missile body, and then the radar, seeker, warhead and even the fuel tank are all "riding" on the engine casing. This not only directly solves the problem of air pressure loss in the air intake, but also reduces the size, windward area and air resistance of the missile to only half of the original size!
What's more, the increase in engine thrust completely makes up for the loss in intake efficiency!
Because later in the experiment, we found one thing: since thrust is directly related to air intake, and the "casing" is equivalent to additional air intake. Therefore, as long as the proportion of the "casing" and the exhaust speed are controlled, the cooling air in the pipe layer can not only generate additional thrust due to thermal expansion, but also the drainage effect of the pulse jet engine outlet further speeds up the air flow of the "casing", which further increases the actual thrust!
According to scientists' estimates, for an engine with an original thrust of 500 kg, as long as the flow rate of the duct is similar to the engine's intake volume, the thrust can be increased by a quarter for no reason!
In addition, this cruise missile was directly modified into an elongated hexagonal cross-section shape under the association of Bismarck's idea of "stealth aircraft" and the British Mosquito fighter shot down by Zeppelin!
Although contemporary technology cannot directly achieve the stealth of the future, it can at least reduce the intensity of radar echoes to a certain extent to reduce the distance at which it can be discovered. Moreover, this hexagonal structure is more conducive to "using cheap wood materials, saving precious aluminum materials, and mobilizing civilian manufacturers to produce" - this is not too good for a nearly disposable cruise missile!
When Goering got the news, he was overjoyed.
As expected, Lütjens and the ship girls under his command are all capable people!
Goering, leaning leisurely in his boss chair and happily dreaming the German dream, couldn't help but secretly wonder whether he could let the project teams under him who were developing turbojet engines add a "casing" on the outside to give it a try.
Goering was even considering whether he should ask Zeppelin, whom he valued most, to review and modify the aerodynamic layout.
(A turbofan version, written as TA-183 and pronounced as F-86, is coming soon!)
-
After development to date, the mother body of the cruise missile is almost complete!
Although the "long-range attack" of anti-ship missiles needs to be improved in search, guidance and route planning, the missile body and engine have made breakthrough progress. Although cruise missiles still need to solve a series of engineering problems and experimental tests, the prospects are definitely bright! Goering was in a good mood and sent all the information about rockets and anti-aircraft missiles to him, hoping that the research team of "Dr. Strange Cat" could bring him more surprises!
Lütjens, Bismarck and even Zeppelin were also very concerned about things like anti-aircraft missiles.
In fact, the development of German rockets started very early. As early as 1939, Dr. von Braun had developed an F-25 sounding rocket with a single body diameter of 2.25 cm, a total weight of 5 tons, and a Walter HWL109-505 solid rocket engine with a thrust of up to 25 tons. Moreover, during the trial production stage, this rocket was considered to be transformed into an "anti-aircraft rocket"! However, because the size and volume of the F-25 are limited after all, the performance is not only limited, but also lacks the potential for further transformation. Therefore, the Air Force Science and Technology Bureau of the German Aviation Ministry RLM found Dr. Guzman and was about to entrust him to develop another thicker and longer F-25 anti-aircraft missile based on the F-55 rocket.
Although the HWL109-505 engine can only work for six seconds, this power is a bit short for high-altitude targets, and Dr. Guzman said that new liquid rocket engines need to be redeveloped. However, Bismarck, who always thinks that things can be simpler and lazy, doesn't care and suggests that several rocket engines can be bundled together, and then the disposable rocket stages can be used to increase the range to high altitudes. As for the final warhead attack period, it can only glide? Gliding is enough for hitting targets like heavy bombers!
Dr. Guzman reluctantly tried it out under "pressure", and the result was that the F-25 with four solid rockets directly reached a supersonic speed of 1500 kilometers per hour (1.25 Mach) during the test flight. Then the Persian cat was stunned to find that he had found an obsessed person among the scientists...
(Lütjens always felt that the color of his hat was a little green, and every time he saw Dr. Guzman running over, he felt annoyed...)
In addition to the rocket itself, another problem that air defense missiles have to solve is radar fire control guidance.
The electron tubes of this era had all the power pins placed underneath the tubes, and there were no printed circuit boards. In order to ensure that the pins would not touch each other directly and cause a short circuit during manual wiring, the electron tubes were made larger than high-wattage light bulbs. Such a large thing had to be driven by a large current, and the extra power consumption and temperature rise that would result can be imagined. Would Bismarck say that the size of the electron tubes she saw in this era were almost the same as the glass food jars she bought in later generations?
However, if we change our thinking, put the tube flat, put the emitter on the left, and the receiver on the right, and then use a circuit board instead of wiring to connect the receiving ends that do not require high current in series, then the size and heat generation will be reduced a lot without changing the power! The size and power consumption of the device will be reduced immediately!
Moreover, even the failure rate of the tube equipment, which was the most troublesome thing, suddenly dropped! The average failure rate was originally measured in minutes, but now it is measured in hours or even half a day!
Several German electron tube research institutes and manufacturers immediately threw their old-fashioned electron tubes into the trash.
(PS: The size of the miniature electron tube is so small that it can compete with the first generation of integrated circuits!)
As for radar guidance, it is even simpler: the traditional radar guidance mode requires the equipment of a radar, and the command guidance mode looks simple but the actual operation process requires the operator to stare at the missile, and then frequently operate and return.
However, the semi-active guidance mode copied by Bismarck from later generations is much simpler: the missile is equipped with only a miniaturized signal receiver, which is tracked by the ground radar station or the illumination radar of the aircraft, and the missile receives the reflected signal and directly attacks the target. The distance parameter is also calculated by the ground radar station and transmitted to the missile (and the reflected echo of the transmitted signal itself can also be used as the basis for the next wave of calculations, as long as a correction is added).
The missile calculates and attacks based on the received target position and distance parameters provided by the radar station. At the same time, since the missile needs to receive information sent by the radar station and the missile only passively receives the target signal, it can also be easily changed to the command guidance mode and anti-(active) interference source mode, which has strong anti-interference ability and low cost.
Moreover, many people even discovered that if a fighter jet was equipped with a radar, and a radar receiver was added to the head of the "large air-to-air rocket" that was planned to attack bombers through area AOE in the preliminary research...
Although the weight of the large rockets hinders maneuverability, and the airborne radar must continue to track and illuminate for several seconds, this thing cannot fight fighters. But for the so-called thousand-plane bombing with poor maneuverability...
As it happens, Germany actually has a research and development plan for the X-4 air-to-air missile! In this way, the problem of manual wire control guidance can be completely eliminated!
Moreover, an infrared guidance system is also being developed. Once this is completed, well...
Even better, if this thing is modified and sold to the army as an anti-tank missile, it will not only help the war situation and bring in a lot of money, but also make a splash in front of the army officers who have always disliked him...
Emmmmmm…………
(Well, Goering has reached the point where he can laugh until his cramps come out even in his dreams)
Half a month passed quickly, and a bunch of projects unexpectedly made major breakthroughs in research ideas. But in the end, everyone was shocked to find that the biggest problem facing the project progress was insufficient computing power...
After all, scientific research is very rigorous and requires a lot of calculations. In this era, if you want to calculate something with a mechanical hand-cranked computer, you have to work hard for a long time. Moreover, the "programs" of these computers are fixed by various gears and mechanical structures. A computer can only calculate one program! And if you want to perform slightly more complicated calculations, the most efficient tool is actually a slide rule...
With such equipment, you can imagine its computing efficiency!
but……
Apart from other things, Bismarck really knew that in addition to the gay Turing (who had been killed in the explosion), there was a otaku named Konrad Zuse in a corner of Germany. He was using his micro-saving savings from working in an aircraft factory in his early years, and accumulating thin iron sheets, movie tapes, broken typewriters and electrical relay parts scavenged from scrap yards. In the basement of his own home, he was working hard to accumulate a machine that was "controlled by binary programs, could use assembly language (and the corresponding computer instruction set) to simplify program input, and could automatically calculate complex problems." This was a fantastic machine in that era.
This is the inventor of computer assembly language, one of the three pioneers of electronic computers (Turing, Zuse, and American-Bulgarian John Atanosov), a genius who was once buried by short-sighted wartime scientific research!
For Persian cats from later generations, electronic computers are already something they are familiar with, whether they are used in scientific research, military command, or military calculations!
Moreover, it is estimated that anti-ship missiles will be mass-produced in the next few years, but my original mechanical computer can only calculate the various parameters of artillery, which is not suitable for the needs of anti-ship missiles. I may have to change the computer after equipping anti-ship missiles in the future... However, if I can use a programmable and faster electronic computer to replace the mechanical computer to assist my sisters in calculations...
If we want to modify anti-ship missiles in the future, it is just a matter of programming the computer - compared with the sophisticated and complex mechanical computer on our bridge, which is not very shock-resistant and may become inaccurate once there is a strong vibration, and has a rigid and inflexible program, the advantage is not that great!
If this thing is done, will my brain become more intelligent? Hehehehe~~
Thinking of the significance of this man and his invention in the present and even in the future, Bismarck, who felt that his brain was not enough, nodded secretly, turned around and looked for his captain and Zeppelin...
A few days later, the fat Imperial Marshal and the capable Golden Knight General Lütjens suddenly showed up at Chuze's home with a bunch of engineers and officers. Then, after Goering and the scientists brought by Lütjens made an on-the-spot appraisal and discussion, Chuze and his family and neighbors were either flattered or incredulous. Chuze's computer room was immediately flooded with investment, and he was directly awarded the title of doctor from an unknown otaku. Then, Goering personally invited him to the Electronics Research Institute and lived a happy life of using "unthinkable before" electronic tubes that were much more sensitive than relays to develop computers...
Well, this research institute belongs to the Air Force. After all, Lütjens’s skinny arms certainly can’t twist Goering’s thick and fat thighs.
Although Redel had no interest in computers and could not refuse to go that day, he must have slapped his thigh hard afterwards and muttered to himself that Lütjens was a traitor or something...
(In fact, Konrad Zuse's computer structure is very mature. All you need to do is replace the relays with vacuum tubes! More importantly, this thing comes with a computer instruction set and assembler!!)
After Conrad Chuze's relay computer used the first generation of small electron tubes, the progress of scientific research became smoother. The repair work of Zeppelin has also been preliminarily completed. The next step is to convert her flight deck into an angled deck and leave the potential for installing a catapult.
Until one day, a newspaper published a really big news...
Chapter 746: Revenge of the Mafia Destroyer
The content of the news is shocking.
The main force of the British and American joint fleet suffered a crushing defeat at the hands of the Italian Royal Navy, and the Malta Fortress also surrendered!
Malta, a fortress base guarding the central Mediterranean, actually surrendered to Italy! And the authenticity of this news was published in the internal reference materials!
After seeing this news, several people were dumbfounded.
