The Wasteland Village base is developing rapidly, and there are more and more hangars. There are also special large hangars, where carrier-based early warning aircraft can be easily inserted without folding the wings.
There were sentries with loaded guns standing outside one of the hangars, which showed that this hangar was very important. Several people were allowed to walk in after showing their identification.
Delano took a deep breath, then took long strides and walked inside.
A beautiful black fighter plane appeared in front of it. It had a diamond-shaped nose and air intakes on both ribs. It looked the same as the J-31. However, this was just the nose. With the nose backward, the fuselage was completely different. .
The canard is in front and the main wing is in the rear. The distance between the canard and the main wing is very long, and additional side wings are added.
The twin vertical tails are tilted outward, with two engines underneath. This is a heavy fighter!
“Looking at the size, it’s smaller than our J-15.” The first impression of Delano was the size! Although he had flown in a simulator before, the simulator was just a cockpit. He didn't know the real size of the aircraft, but now he had an intuitive feeling.
However, with such a large delta wing, there must be a lot of fuel inside.
“So, is this a medium-sized aircraft or a heavy-sized aircraft?”
Those that either have two engines are heavy-duty aircraft. Whether it is the MiG-29 or the F-18, although these aircraft have twin engines, they can still only be classified as medium-sized aircraft because they all use two medium thrusters. At the same time, the take-off weight is also limited.
Now, what type of aircraft is this in front of you?
“Its engine is the same as that of the J-32. Do you think it is a medium-sized aircraft or a heavy-duty aircraft?”
One machine has a thrust of fifteen tons, and two machines have a thrust of thirty tons. What else can we say? It is a proper heavy-duty machine!
"Really? Then it can fly from the deck of the aircraft carrier even without a catapult, right?"
“Of course, this has been verified in land test flights. However, we still recommend using a catapult so that the engine does not need to use afterburner.”
This maximum thrust is measured when afterburner is turned on. In this case, fuel will be consumed at an alarming rate. If a catapult is used, only the maximum military thrust is enough!
“That’s right, it’s time for us to test our adaptability to the aircraft carrier, right? I request the first flight!”
“I’m afraid this won’t work. The first flight is very critical. We need to find experienced pilots to fly it.”
“I also have a lot of experience!” Delano said: “I have flown more than three hundred hours in the simulator!”
Even though there was no J-20 in the Wasteland Village base before, it had already been equipped with a flight simulator. When Draenor was bored, he would go up and fly a few. He had already mastered the game and was waiting to play with the real thing.
However, no matter how much time you fly on a flight simulator, it is still different from a real airplane, so of course Wu Shengli would not agree.
“No, the candidate for the first flight has been determined. I have flown more than two hundred hours on the J-20, which is real.”
"No matter how much flying there is, what's the use? Ejection takeoffs, arrested landings, etc. are not something test pilots can fly. Only veterans like us Navy pilots can fly this." Delano said, "You let an Air Force test pilot fly it?" Is it possible to arrest the landing? This is a carrier-based aircraft, not an ordinary Air Force aircraft."
Delano has never flown a real aircraft, but he has flown simulators for a long time, and he is also the best carrier-based aircraft pilot. Now this aircraft comes to the Navy base for test flights, either for test flights on ordinary subjects or for test flights and take-offs. Landing, so he felt he was the best at it.
“Mr. Qin, what do you think?”
"I don't care." Qin Tao directly acted as the shopkeeper. He had better not get involved in this kind of thing. After all, if there was an accident and the plane crashed, he couldn't bear the responsibility.
Delano looked at Wu Shengli.
Wu Shengli coughed dryly, and then said: "Then let's do it. You compete with our test pilots, and whoever gets the best result will fly."
“Competition? Comparing to what?”
“Fly the simulator, take off and land.” Wu Shengli said.
With the continuous development of computer technology, simulators have simulated actual conditions so realistically that the J-20 does not need a two-seater trainer type. As long as a full set of training is completed on the simulator, it can fly solo.
Now, compared with the takeoff and landing of carrier-based aircraft, of course, you can also compete from the simulator.
Hearing what Wu Shengli said, Qin Tao secretly lamented that his father-in-law had made a mistake. Compared with the simulator, Lei Zi would definitely not be able to compare with Delano!
“Okay, let’s compete.” A voice came from outside.
Lei Zi walked in with a smile on his face: "The first Su-27 to land on the Kuznetsov was Pugachev. Although he was a test pilot of the Air Force, he was still Lao Maozi's first A fixed-wing carrier-based aircraft pilot. Although I am also a test pilot of the Air Force, I have also flown many carrier-based aircraft landings. Recently, I have also flown many times on a trainer aircraft. I don’t think my The technology is worse than yours.”
Navy pilots look down on Air Force pilots. In their eyes, flying smoothly and smoothly is not considered a real fighter pilot at all. Only exciting flights such as ejection takeoff and arrested landing are real pilots.
Although Lei Zi is a pilot of the Air Force, he will never think that his flying skills are worse than those of the Navy pilots. He has always liked to challenge high difficulties and try all kinds of impossible. As the chief test pilot of the J-20 Commander, he has already prepared the J-20 to board the ship!
Delano looked at the person who appeared at the door with pride on his face: "Okay, what are you waiting for? Let's give it a try!"
“Well, the banquet is about to start. Let’s go to the banquet first and wait until after we finish eating.” Wu Shengli said.
“No, let’s finish the competition before eating.”
Delano is not afraid of anything, and he won't take anything the leader says seriously. Wu Shengli has no choice, so let's compete. If you lose, let's see if you are still in the mood to eat.
So, several people came to the flight simulation room. After entering, Delano noticed that something was wrong.
“Why is there an extra simulator here?”
A brand new simulator is placed in the center. You can see that the appearance of the simulator is very similar to the nose of the aircraft we just saw. It should be the J-20 flight simulator. As for adding another simulator? Is this kind of aircraft going to be equipped with troops on a large scale?
"Because our cockpit has been modified." Lei Zi said: "In order to allow the pilots to better adapt to the new aircraft, a new simulator is required."
“How else can the cockpit be modified?” Delano was very curious. As he said this, he approached the brand new flight simulator, looked inside, and was stunned: “Single LCD screen?”
The first flight simulator still used three LCD screens. After all, three-one-up is the most classic cockpit layout of this era, and is used by many aircraft. However, with the continuous advancement of LCD screen manufacturing technology, large-scale cockpit displays LCD screens have finally matured, so the J-20 has also begun to use this advanced single LCD screen, which looks very beautiful.
The front HUD seems to have expanded in area. The canopy above is one piece, just like the F-16's overall canopy. However, although it is one piece, there is still a partition at the front end of the canopy, which should be Considered for the purpose of increasing strength.
“Yes, this No. 04 prototype has been further optimized in design, and the entire cockpit has been reduced in weight by 200 kilograms through various means.” Lei Zi said at the side. “Lose so much weight?” Delano was also surprised.
For aircraft, weight reduction is very important. The lighter the weight, the more advanced the performance of the aircraft. However, it is not easy to reduce the weight of the aircraft. Take the Su-27 fighter jet as an example. Because the radar is overweight, the design In order to reduce the weight of the aircraft, the engineers went to any lengths, even drilling holes in the beams of the aircraft, which resulted in rickets.
In fact, Da Mao's designers were still restricted. After the domestic J-11 came out, there were no other improvements. They just changed the processing technology of the cockpit instrument panel from casting to stamping and forging, and the cockpit instruments were reduced. Two hundred kilograms heavier!
When the watch shop transitions to LCD displays, the weight will be further reduced. When the transition from three LCD screens to one LCD screen, the weight will also be reduced. Aircraft designers racked their brains and came up with various solutions, and finally The weight of the cockpit has been reduced by another 200 kilograms.
For carrier-based aircraft, landing gear, landing hooks, etc. will cause an increase in weight, and the increased weight must be reduced through other means, so that the performance of the fighter can remain the same as that of a land-based aircraft.
Therefore, this No. 04 carrier-based aircraft uses a lot of advanced technology, uses larger composite materials, etc., so that this aircraft can achieve the performance of a carrier-based aircraft without much increase in weight compared to the prototype. .
"According to the needs of the Navy, the Navy's carrier-based aircraft are equipped with phased array radars. This radar gives the fighters more powerful performance. There are also some differences in the operation interface. However, today we are only better than the carrier-based aircraft. Takeoff and landing, I won’t introduce these." Lei Zi said, reaching for his helmet.
Although this is just a flight simulator, you can train normally without wearing a helmet. After all, the simulator cannot simulate real overload. However, the feeling of wearing a helmet is different from that of not wearing a helmet. When training on the simulator, you have to pretend to be like A few will do.
Delano glanced at Lei Zi's helmet, and then his eyes remained fixed there.
"What's wrong?"
“The shape of this helmet is very weird.” Delano looked at the bumps on the back of the helmet, which were like fly eyes, enough to make the scalp of people with trypophobia go numb.
"Yes, this is the latest flight helmet developed by us in China." Lei Zi said: "The bumps on this helmet are positioning points, which are used to determine where the pilot's head is to be moved. They are the same as those we used before. Compared with Lao Maozi's helmet sight, it is lighter and lighter, after all, there are just some magnets added to the bulge."
The bumps on the helmet look weird, but they are actually very simple. Two magnetic field sources are installed on both sides of the canopy to generate a weak three-axis orthogonal magnetic field in the cockpit. Each bump is a permanent magnet. When the pilot When the head rotates, the permanent magnet will cut the magnetic field lines, thereby calculating the offset of the pilot's head, so that you can know where the helmet has turned. (It is also said to be an infrared sensor.)
Fighters have to carry out large overload maneuvers, such as 5G overload, and the original two kilograms will become ten kilograms. Therefore, the smaller the weight of the helmet, the better. If it is too big, the pilot's neck may not be able to bear it.
Through the introduction of the Su-27, China has also simultaneously acquired the technology of helmet sights. However, this helmet sight uses the photoelectric scanning positioning principle, and the aiming module on the pilot's head is equipped with three light-emitting diodes. The measurement module is equipped with two small prisms that rotate in opposite directions. It uses triangulation to measure the normal offset of the pilot's head and follows it with the fire control computer. In actual flight training, ordinary pilot helmets do not carry this Only the base was left of the thing, but I just disliked the fact that it was too heavy.
Now, through more advanced technology, lightweight and efficient layout can be achieved.
"Really? This helmet is really advanced, can you wear it for me?" Delano was eager to try it.
Leizi shook his head: "No."
“Why? Isn’t it just a helmet?”
Lei Zi smiled: "This is not an ordinary helmet. This is the most advanced helmet made in China. Unlike our previous helmets, which were divided into three sizes: large, medium and small, this helmet is one for each person."
"What's the meaning?"
“Helmets are specially customized. If you want to get this kind of helmet, you must first scan your head characteristics, and then the relevant unit will produce it specially for you.”
For private customization, do you need to scan the head features? Delano's eyes widened in surprise.
At present, the common helmets in the world are also divided into three sizes. Although this allows users to use it, many problems can still be found during actual use. For example, those wearing a large size are a little too big, and those wearing a medium size are a little too small. In this case, you need to adjust the straps, but it is actually still uncomfortable.
And it’s impossible to design a helmet of one size specifically for certain people, so you can only make do with it. Now, it’s one-on-one, individually customized, and each person’s helmet is strictly suitable for them!
Lei Zi's helmet is the first of this kind of professional helmet. In addition to the normal logo, there is also the word "Lei Zi" on the side of the helmet. Since it is privately customized, of course it must be engraved with his name. Don't mess with it.
"Aside from the pits on the back, the glass in the front also has special features." Lei Zi continued to introduce this flying helmet to Delano. This is not to show off. With the test flight of the J-20 carrier-based version, naval ships will Aircraft pilots must also start training on this kind of aircraft, and they must have matching helmets. Delano must be among the first to fly this kind of aircraft.
“Is this glass a monitor?” Delano asked.
"Yes, it also has a display function." Lei Zi introduced: "This is a display made with our most advanced technology. It can now display flight parameters, status awareness, fire control data and other functions. Later, It can also display video footage, battlefield footage, etc.”
Delano opened his eyes wide, he was really shocked.
A small pair of goggles actually has this function?
“If these parameters can be displayed, then why do we need a HUD?” Delano suddenly realized that the HUD can be completely removed, leaving only the helmet-mounted display. It’s so classy.
Furthermore, it can also display the screen!
"At present, we are still relatively conservative. After all, heads-up displays have been on fighter jets for many years. Our pilots do not necessarily like to wear goggles when flying. Moreover, our helmet display system currently has data delays. Situations, even if brief, can be fatal."
In fact, in another time and space, the Yankees' F35 fighter jet was the only model that removed the cockpit head-up display and completely replaced it with a helmet-mounted display. In actual use, many problems occurred.
The biggest one is of course data delay. The Yankee relies on the camera on the belly of the aircraft to achieve the effect of see-through eyes. When the pilot lowers his head and looks down, the helmet display can display the following graphics, as if his eyes are directly through It's the same as passing through the fuselage.
Sounds good, but in fact, this kind of helmet-mounted display has a big problem: data delay! It is impossible for the camera to be directly connected to the helmet display, and it requires computer processing. Even if the speed is fast enough, there will only be a delay of a few tenths of a second.
In an air combat, this delay can be fatal. People who play computer war games should also know that if the computer is not powerful and drops a few frames, someone else may kill them.
Not to mention airplanes, cars that use cameras instead of rearview mirrors also have this delay problem. When overtaking on a highway or something like that, if you encounter a data delay, it may be fatal. Although the electronic system is very high-end, , it is not as direct as two ordinary rearview mirrors.
So, although domestic helmet-mounted displays already have various advanced functions, the cockpit HUD will not be removed.
Delano nodded, still looking at the helmet-mounted display with keen eyes, looking forward to it: "When can I have this kind of helmet?"
“The Navy’s first batch of 20 pilots who will fly the J-20 will be uniformly scanned on their heads and customized.” Wu Shengli said.
“Can I scan now?” Delano couldn’t wait.
“Are you sure you want to scan now?” Wu Shengli asked.
“That’s right, now, I can’t wait any longer!”
Delano was caught by the helmet and seemed to have forgotten the purpose of coming here.
“Okay, let’s go to the base hospital.”
