#科学火箭叔#科普#文化#英国#航母#伊丽莎白女王

If you pull together several mainstream aircraft carriers around the world Compare the words You will find a strange place That’s the Queen Elizabeth of England. It’s out of place. Whether it’s the American Ford China’s Shandong No. Or the French Charles de Gaulle First of all, there is only one ship island.

But the Queen Elizabeth has two. Second, ah The first three aircraft carriers all use inclined flight decks. But the flight deck of the Queen Elizabeth Straight from start to finish Er, what is he doing this? I’m an encyclopedia rocket book Today we will talk about He

First, let’s talk about the problem of two kendo. To confuse the enemy You’ll never guess where my captain is sitting. Just like the president’s motorcade always has several identical cars. Is the front and back arrangement the same Apparently not. The reason is not above the deck but hidden beneath the deck

Inside the aircraft carrier’s engine room Queen Elizabeth. Two identical sets of gas turbines were used. as its source of power Therefore, two sets of smoke exhaust systems are needed to exhaust the aircraft outward. In a more popular way is that it has two big chimneys These two big chimneys

Obviously, it’s impossible to come out bare. Not on deck? Since we still need to set up a ship island on deck Then the best plan is definitely combine the chimney and the island Actually, that’s what everybody does. But the situation of the Queen Elizabeth is a little more special.

Its two sets of power system The distance between the front and back is especially far away. So you’re either designing a very long island. Wrap both chimneys inside at once Or you have to arrange two islands. to wrap the two chimneys respectively We already know his last choice.

This is the world’s first two-island aircraft carrier. Hey, why did he choose like this before? Shouldn’t you be curious first Why would he want two identical power systems? And you have to space them so far apart. Well, if you ‘ve guessed Just walk in the comment area.

The reason is actually very simple ah The British are afraid of the Queen Elizabeth Did you repeat the mistakes of the Royal Ark? November 14, 1941. Because the German U81 submarine launched the torpedo Hit the side of the Ark Royal caused a huge explosion

And will fitness tear a long 40 meters of big mouth A lot of seawater poured in. Within minutes, the central boiler room was flooded. Cause the main engine to stop running The power system is completely interrupted. So, ah, this ship during World War II. Britain’s most famous aircraft carrier is stuck in place.

Waiting for the fate of the final sink to the bottom of the sea Well, if only he had a second boiler The British are remorseful That’s why there are two separate sets on the Queen Elizabeth. Is the gas turbine so open? is for redundant backup

Two chimneys to improve the survival rate once the war is damaged. Then two chimneys Hey, why don’t we build two ship islands? Although this will cause physical isolation Let the front take charge of ship control. and the two rear teams responsible for flight control It’s not easy to cooperate

Especially considering the carrier aircraft take-off and landing In fact, they are very dependent on aircraft carriers. Provides accurate heading and speed Therefore, it is even more necessary to test the running-in between the two buildings. Oh, but other than that Dividing into two buildings is better than combining a big hole.

For example, you can save a lot of deck space. Even between two islands You can also install a lift Greatly improve the utilization of the deck For example, two small islands Less air turbulence than a big kendo This has played a positive role in the safety of carrier-based aircraft

Another example is the separate island. Improved efficiency of ship control and flight control, respectively Located in front The island, which is mainly used for ship control, was able to get closer to the ship’s crew. Thus providing a better view for the crew Can steer the ship better Especially in narrow tunnels.

And located in the rear What about the island, which is mainly used for flight control? So you can install 290 degrees Encircling huge windows up to 3 meters The entire flight deck from the stern to the archer is in full view. So you can make more accurate judgments and decisions.

Ah, it’s okay to say Separate computers can be fitted with separate radars Reduced interference and blind spots between the two And separate computers can also be made separately. In terms of difficulty, it has been reduced a lot. So it looks like this The Queen Elizabeth’s twin island shape is really well-founded.

So he canceled the oblique flight deck Is it equally justified? Well, it does look like there’s nothing wrong with it. The reason why other aircraft carriers have to put the flight deck next to it obliquely It’s because their carrier planes are sliding to the deck.

The landing was slowed down by hooking up the arresting cable. And this way has its specific risks. Just in case the plane didn’t hook the barrier cable. He has to go around immediately. The deck of the shoes creates conditions of safety for him Imagine that. If there is no inclined deck

But straight forward words Er, it’s hard for him to avoid the plane parked in front of him. The result is likely to be like this But what about the Queen Elizabeth aircraft? They are all models with vertical take-off and landing capability. Helicopters, naturally, don’t say much. Fixed-wing aircraft using the f35

It can hold on to that 12-degree ski jump deck. Short-distance takeoff with the help and then build it into a direct vertical way Since the left key is like this, why do you still need to tilt the splint? Just make it into a neat rectangle Is there obviously room for more affluence

Do you think the reason is also very sufficient As far as I’m concerned I like the shape of this aircraft carrier very much. So what about you? I’m Uncle Rocket. Write your opinion in the message and tell me This is a box of Kodak film Hey, it’s been years

If you also know Kodak film Please type one in the barrage But in fact, Kodak also makes lenses and cameras. If you also know this Please hit two in the barrage And then? He actually produced a Hubble Space Telescope. The main mirror above If you even know this

Please hit three in the barrage But it’s a pity This mirror has never been in space. He is currently on display at National Airlines in Washington. Inside the Space Museum. He was taken to heaven by Harvard. It’s a mirror made by another big optical manufacturer, Platinum Elmer. But the irony is that

That mirror is flawed And the HKUST mirror that was left behind was quite perfect. Er… Why would NASA put a flawed mirror launch into space How did such a low-level mistake happen? Is the encyclopedia of fire archery Today we tell the story behind this. Back to 1970.

Due to the success of previous orbiting observatory programs NASA was greatly encouraged. Others have officially launched the space telescope project. By 1977. After many twists and turns He finally got the money he needed to build a space telescope. That’s about 0.3 billion dollars. Expected cycle of about 6 years

At the same time, this space fighter has its own name. Hubble One Memorial Edwin, the astronomer who discovered the expansion of the universe Hubble’s all right. After having the funds Production can begin. As the core of the whole telescope The manufacture of the main mirror is particularly important

It plays the role of gathering light alas Light collected from the lens barrel Reflected on a smaller mirror What about the latter? It further reflects the light onto Hubble’s various imaging instruments. The reason to reflect twice is to be in the shortest possible shot Install the longest possible focal length

In order to impinge on the main mirror Any part of the light perfectly converges at one point It needs to be polished to a precision Up to 10nm curved surface The diameter of the main mirror is 2.5 meters. 25 million times the polishing accuracy Difficulty to think

And know, ah, ah, the one who took over this important task is platinum Elmer. What is the company’s position in the industry? Everyone can check it out for themselves. Anyway, he’s definitely NASA’s best choice. Not to disappoint NASA. Platinum II Mo also released his own trick

Use a special custom computer to automate the polishing of the mirror. This is nothing now But it was definitely a super cutting-edge technology at the time. And it looks like the most promising The process has reached 10nm accuracy. But to be on the safe side

Nasa also requires that they must be part of the production subcontract out Make a spare motherboard to power it up Guess who he subcontracted Alas, it is Kodak Because HKUST is producing camera equipment and optical lenses. Has accumulated a fairly good reputation It will be hand-polished to make This Hubble’s big mirror

So what about the production of the main reflector in 1979? The two companies started at the same time. At that time, Kodak suggested We should cross-check each other’s mirrors. in order to ensure that nothing goes wrong But platinum two ink obviously don’t agree with ah In his eyes

Kodak is probably a backup of soy sauce. What if nasa hadn’t insisted on having you? In fact, do you just have to do it Also teach him a little check This is a computer model. Do you handmade people understand Ah, I’m sorry. The play was a little too much.

But I guess that’s what it means. So then cross-checking naturally didn’t happen. By the end of 1981 After nearly 2 years of hard polishing No two ink Finally, a whole piece of ultra-low expansion glass It has become a concave running 5kg After cleaning and plating a highly reflective aluminum film?

This main mirror is officially completed. But before you actually put it on Harvard? He still needs to pass a series of very strict tests. ah, it mainly includes two aspects One is to see how well it tolerates the environment. After all, the vibrations at launch and the harsh environment in space

It’s a big test for him. What about this? There’s nothing to say It must have passed smoothly. The other is to look at its grinding accuracy. Whether it can meet the design requirements This is a little more complicated So the scientists used something called a zero-difference corrector. of the equipment

To help them check the lenses This thing itself is made up of mirrors. It is about 76cm high About 50cm in diameter A concave mirror with a middle opening on the upper and lower sides. And then there’s a field lens where the light goes out. Theoretically

When you place it 11 meters above the Hubble primary mirror After driving a laser beam will create a flat wavefront stripe on the mirror surface Well, this shows that there is no problem in polishing the mirror surface. And if there are twisted stripes This shows that the mirror is a problem

The result of the test is perfect It’s just like not entering Elmo’s expectation. So Kodak’s mirror It really became a superfluous decoration. Not even a test. Pull it directly into the warehouse What happened after that? We all know very well 1990 Apaw took a shockingly blurry photo.

At that time, the world’s Chinese nasa was dead to the extreme. After careful study They found that they had made a perfect mistake. Do you remember the zero-difference corrector we just talked about? Is there a few mirrors in it? It turns out that the engineer was installing one of the mirrors.

It’s a little crooked. The result is just the perfect correction. Errors appearing on the Hubble primary mirror Straighten the lines that should have been twisted. God, the so-called “no coincidence, no book” This is probably the most perfect interpretation of it It’s even sadder. Everyone finally thought of it at this time

There is still the mirror of HKUST in the warehouse. So I pulled it out with trepidation for a test. He’s really perfect. This face hit Even though it’s been almost 30 years It’s as if I can still hear the sound of popping Too bad it’s too late

It is unrealistic to replace the main mirror in orbit The only thing to do is to take the perfect mistakes made during these tests. Copy to space It has been delayed for more than 2 years. After spending hundreds of millions of dollars The Hubble with the corrective mirror can finally work normally.

Thirty years have passed. His countless achievements have been gradually forgotten. The episode that almost dragged him into the abyss But I think the whole world chooses to forget Kodak will definitely not forget If time reverses Bergin agreed to Kodak’s cross-checking proposal. Hubble also used Kodak’s mirror. Will he still be brilliant now?

I’m Uncle Rocket Focus on me Tell you a different science story. a 10 warthog You said he was a plane Don’t know is on the plane of self-esteem Still hurting his self-esteem Indeed, he is too special So today, let’s have a good talk about him. What about Fulda Canyon in the 1970 s?

Definitely one of the most tense areas in the world Why? Because this is about 10km wide About 50km long Not very steep canyon It just connects the East and West in the Cold War. As long as the Soviet Union in the east crosses this canyon You can drive straight in.

A sweep of the plains of Western Europe After breakfast in Frankfurt We’ll be in Paris for dinner that day. And NATO in the west, whatever it takes Stall the footsteps of the Soviet Union here Otherwise, all the way west to the English Channel

There will no longer be a natural barrier to stop Soviet tanks. So in order to prevent, uh Or to win. World War III could break out at any time Both sides in this under the force is unprecedented ah More than 300000 troops, to be exact. 3000 tanks. 3000 armored vehicles The 5000 Artillery

1000 helicopters. and thousands of fighter jets and hundreds of missiles with nuclear warheads All around here to deploy and unfold It is in this case The need for a 10 was born In order to meet the so-called United States Army The new concept of air-ground integrated warfare

Simply put, the Army wants an airplane. Can help them from the air Picking up Soviet tanks at close range? I said close distance is really close It is close to the height of 3 hundred meters from the ground. The aircraft is close to its own ground forces in need of protection and support.

Also close to enemy ground forces that need to be attacked and threatened So that means it must not be a normal plane For example, first, his deployment was to follow the ground troops. Ah, this is very easy to understand The whole purpose of his existence is to support others.

So as a normal aircraft should have ground support? He can’t get it. Hey, since I can’t get it Then you have to find your own way. Second, you can think of it as a sponge. instead of a sponge that absorbs water It’s a sponge that sucks all kinds of ammunition.

This is also very good to understand You’re so close to the ground Not flying so fast. Don’t you have to pour all the ammunition on you? Have you ever seen sponge cells disperse? No, right? So it should also be even if it sucks a lot of bullet holes

Also still want to be able to maintain a whole piece of fly back to the base The third light will fly. How can light be beaten? The most important thing is to be beaten like Rocky You have to be able to hit hard. So basically it’s a

A plane built to make the artillery fly. This seven-barreled 30mm ga eight avenger automatic cannon Compared with the beetle nearby, it is in this posture. Alas So the whole belly of the warthog Almost can only install it ah Even the front landing gear has been wronged to the side.

But five g is far from over. Under its belly and wings There are as many as 11 mount points. A total of more than 7.2 tons of additional weapons can be hung. from a gm six five calf to ground missile to ai am nine rattlesnake to air missile

From laser-guided bombs to unguided conventional bombs From rocket launchers to electronic warfare pods A Traveller Full of Weapons It does look pretty cool. All right, three points above. How do warthogs do it? Let’s say a month First flexible site adaptability He relies on the engine hanging above the fuselage.

Keep them away from rough terrain Gravel or foreign matter raised during takeoff No ground support What should I do? Hey, look, there is a hidden a p u That’s the auxiliary power system to start the two main engines. And before that, it powered the electronics on the plane. And usually for other fighters.

It is not a B option. Because it can be connected Then came the big head. Super leather durable and anti-beating He relies on a large number of interchangeable parts. From engine landing gear to empennage Even -1. Can be exchanged with others Change with yourself. Change from left to right

Do you think these engines are unusually far apart? Alas, deliberately for it It’s about trying to avoid them both getting hit at the same time. And then it happened that none of them worked. The matching warthog There are two completely independent hydraulic systems on the body

Used to control the scaling of all pasta landing gear And the supply of guns and so on. Even if one hydraulic system stops working It will also be supported by another system. At worst, both systems are on strike. Warthog’s various control pages Can also be operated manually without hydraulic pressure

Not to mention, it will definitely allow the pilot to fly the plane back to the base. But at least it bought him enough time fly out of the danger zone Then parachute to escape Actually, it’s a bit of an exaggeration It’s landing gear. What if there is no hydraulic pressure to put down

No problem Look at these two main landing gear wheels. It was never intended to be completely retracted into the landing gear bay. Can’t put it down Then just drop it It can still provide a certain amount of ground clearance and cushioning for tour rentals. That is the loss in the controllable range

Well, although he’s ready to be hit But what should be prevented is still to be prevented. He’s carrying white stripes and flares. More than any other American fighter Here, four on each side of the rear of the landing gear pod And here, each one with four more.

There were 16 videos of jammer launchers. And they can be detected. After being exposed to enemy radar and laser self-launched. In addition, it is widely spaced double vertical tail And not just to improve flight stability. They also have an important feature to look at from the back.

Two vertical tails shut the engine inside perfectly It also shut the hot exhaust between the channels. Reduces the possibility of warthogs being tracked by infrared heat-seeking missiles Hey, what if I was hit next? Pilot has bathtub protection I just talked about this two days ago. Fuel tanks are protected by flame retardant foam

The fuselage wings have a lot of redundant protection In short, it is always the one who can laugh until the end after being beaten. During the Gulf War 8100 sorties Destroyed 1000 more tanks After 2000 military vehicles and 1200 artillery He only lost the starting price himself.

Well below the Air Force’s initial expectations. It’s a tank. It’s not too much to switch on and off. But say it’s an excellent plane. The pilots of other fighters are not very happy. In their eyes What kind of plane is this? This is clearly a slow to be easily hit Stupid. Pay attention

What they mean is that the bird flew from behind and hit it. Hey, is this too much? Because in fact, if you weren’t comrades in arms If it’s hard Who wins a dog fight in the sky to cure diseases? Slow Tour But he’s steady

And the turning radius of the most critical indicator of combat in the air It has an advantage that even the f22 cannot shake. The turning radius of the warthog is very small So you can point the nose at each other faster. And what’s worse for his opponent. Its gun is 30mm

It is 10mm more than others. No wonder people love each other.
