The runway was approaching, and Salah tried hard to control his fear. He silently told himself in his heart: Believe in the instructor, believe in the instructor, this is how the carrier-based aircraft lands!

Finally, the plane bumped violently, and the landing gear had hit the runway. It continued to slide forward, and his body began to jump forward. The seat belt pulled his body tightly, and he felt that his eyes were beginning to become dim again.

.

He didn't know when the plane stopped or how it slid back to the apron. When the canopy opened, he stood up hard and tried to walk down the gangway, but for some reason, two

My legs are shaking involuntarily!

Shameful, so shameful!

"Salah, what do you think?" Delano said to him: "After this flight, do you have a more comprehensive understanding of the takeoff and landing of our carrier-based aircraft?"

"A dancer on the tip of a knife, an eagle in the blue sky." Salah said: "Sure enough, the takeoff and landing of carrier-based aircraft is the most difficult. This is just a small trainer aircraft. If it is a larger fighter jet,

It will definitely be more difficult to take off and land. I think it will take a lot of effort and hardship to master the takeoff and landing of this kind of aircraft."

U.S. Navy carrier-based aircraft pilots have never looked down upon Air Force pilots. In their eyes, the Air Force's smooth flying cannot be considered a veteran pilot at all. It is nothing at all.

Now, Salah has realized that this kind of take-off and landing is not something ordinary people can bear.

"It seems that this kind of take-off and landing is a big challenge for us." Salman also understood that if they want to realize the take-off and landing of carrier-based aircraft, it will not be so easy. Their elite pilots have already obtained

This conclusion: Carrier-based aircraft are not something that ordinary countries can handle.

Therefore, they might as well place the J-31A on land. As long as they are well protected, aren't those Dongfeng-3 missiles also well protected?

He thought for a while and then continued: "Mr. Qin, your aircraft is of three types. The vertical take-off and landing fighter has never been seen. I wonder how the development is going?"

"Everyone, this aircraft is the most technically difficult. However, we have achieved initial results. If you want to see it, we can arrange a vertical take-off and landing fighter performance next."

"Okay, great!"

"Where are the fighter planes?"

"Have you seen it? Aren't there three black fighter planes on the tarmac over there?"

Now, when you see the black-skinned fighter plane and look at its general appearance, you can tell that it is the J-31A. They are used to seeing such an aircraft in the naval aviation training base in the east and don't think there is anything wrong with it.

of.

However, when Qin Tao said this, they suddenly reacted: "Could one of them take off and land vertically?"

"That's right." Qin Tao nodded: "When we were designing, the three-type, vertical take-off and landing fighter aircraft had the same appearance as the other models. If you don't look closely, you can't tell the difference at all."

The American JSF also has three types of aircraft. However, when the vertical take-off and landing F-35B is put together with the other two models, you can immediately spot the difference between them: this type B is obviously fatter, with a full circle of fat and plumpness.

The F-35B gave the whole group the title of fat electric weapon.

So, what exactly causes it to be fatter?

The first is the huge lift fan. The diameter of the F-119 is 1.17 meters, and the diameter of the lift fan is 1.27 meters. To fit this thing in, the body must be thicker.

The second is the range requirement. The huge lift fan takes up space in the aircraft body, but the range still has to be up to standard and the wings have to be folded. So we can only find ways to make the aircraft body fatter and carry more fuel.

This aircraft developed by Mingzhou Group will not do that. It has three models in one aircraft. It is intended to use common parts to reduce production costs. It is just like BMW's three-cylinder engine, with a single cylinder of 0.5 liters.

The three-cylinder is 1.5 liters, and the four-cylinder is 2.0 liters. This makes most parts common. The cost saved by the car company will become profits, and it will certainly not be passed on to users.

If the shape of the vertical take-off and landing model is different from that of other aircraft, it will be difficult to produce them on the same line.

Therefore, the fuselage of a vertical take-off and landing fighter is the same as others. As for the internal fuel space occupied, the range will be reduced in the worst case. You can't have your cake and eat it too. You can't have both vertical take-off and landing and a long range, right?

Look at the other two fighter jets of this era, whether it is the Sea Harrier or the Yak-38, they are both proper mast defenders. Don’t look at the Sea Harrier boasting that it has a range of more than 2,000 kilometers. In fact, the combat radius of vertical takeoff and landing is also

It's only one or two hundred kilometers, and short take-off and landing means a combat radius of 300 kilometers. This vertical take-off and landing fighter of ours can extend the combat radius to six or seven hundred kilometers when ski-jumping, which is already very good.

.

Vertical take-off and landing fighters are mainly used on amphibious assault ships. When they are needed, the aircraft carrier's carrier-based aircraft have already completed the task of seizing air supremacy. The amphibious assault ships can launch attacks from two to three hundred kilometers away from the target.

Range is not an issue.

Of course, in the future, when the new turbofan-15 is successfully developed and the fuel consumption rate is further reduced, the range of this vertical take-off and landing fighter can be increased by several hundred kilometers, which will be more convenient.

The Saudi visitors originally had no reaction to those black-skinned aircraft, but now, when they heard that there were vertical take-off and landing fighter jets among them, they immediately became interested.

"Mr. Qin, does this mean that this aircraft has been developed and matured?"

"The research and development has matured, but we are responsible. It is impossible to bring such a brand-new aircraft directly to the market. We must conduct a large number of flights in our own hands to expose various hidden defects.

, when it is delivered to the troops, it will definitely be the most mature aircraft, and now it is being used and tested at our Wasteland Village base."

This chapter is not over yet, please click on the next page to continue reading the exciting content! "Then can we enjoy it?"

"Of course you can. Let's take a closer look first and let our designers introduce it to you. After the static tour is completed, we will give you a flight show."

"good!"

Everyone took long strides towards the plane. Salah had recovered and was walking at the front.

He has given up on catapult takeoff and arrested landing. If he were to fly this vertical takeoff and landing fighter, it would be much easier to do a ski jump takeoff and vertical landing!

Pleshakov did not come. Although Qin Tao had already sent out an invitation, this old aircraft designer was no longer interested in fame and fortune. He just wanted to continue his research, so it was Zhao Dangsheng who made the introduction to everyone.

.

When everyone passed by, Zhao Dangsheng was directing a group of ground crews to perform maintenance.

"Old Zhao, come and introduce our guests. You must have met before, right?" Qin Tao shouted.

Zhao Dangsheng put down his work and came up to him: "Of course we have met, Mr. Salman, we have met again. This time you are interested in our vertical take-off and landing fighter jets?"

"Yeah, I didn't expect your fighter jet to be mature. Let's come over and take a look." Salman said.

"Well, let's take a look at the appearance first. From the appearance, you can't see much difference. However, when you turn to the back, you can see that our engine tail nozzle is very different from other fighters."

You can't see any difference from the front or side, but the difference between the chrysanthemums is huge.

The vertical take-off and landing engine in front of you can rotate the tail nozzle downwards more than 90 degrees from a horizontal state. It uses a unique three-stage rotation structure. Through rotation, it cleverly changes the direction of the nozzle, which is also vertical.

Core technology of take-off and landing engines.

However, these parts are all wrapped in the fuselage. What everyone sees is still an ordinary divergent-convergent tail nozzle, and it seems that there is no difference!

"Now, we are undergoing maintenance, and we can demonstrate it to everyone." After Zhao Dangsheng finished speaking, he shouted to a ground crew member: "Test the tail nozzle rotation!"

"yes!"

In everyone's surprised eyes, the body skin under the engine tail nozzle was folded to both sides, revealing the three-stage rotating structure inside. The two middle sections began to rotate, and the tail nozzle began to move downward.

Sended.

It was like science fiction! Everyone present opened their eyes wide and watched this incredible scene.

The tail nozzle rotated gracefully from horizontal to vertical before their eyes, and then converged to the minimum, which can provide the strongest thrust.

The internal mechanisms are exposed, and the pipes are full of industrial beauty.

"Beautiful, so beautiful. I didn't expect you to be able to break through these technologies." Salman said: "Eastern's technology is already the strongest! We are very satisfied!"

Of course they know that the United States' JSF joint attack aircraft is still in the research and development stage and is even difficult to produce. This Dongfang fighter has begun to be delivered. In this industry, the United States has also fallen behind!

They were full of praise.

"Let's take another look. In order to propel this fighter jet to take off, we also need a special engine in the front. We use a lift fan. At this time, when the rear rotating nozzle moves, the lift fan in the front also moves.

will open."

So, everyone stepped forward, got under the plane, and looked up at the lift fan.

This is the biggest difference between it and the Yak-141. By replacing the lift engine with a lift fan, the problem of the tail nozzle burning the flight deck is avoided. This allows this vertical take-off and landing aircraft to eventually mature, although this thing will occupy valuable space on the airframe.

space, but it is also necessary.

Other ordinary land-based and ship-based models have large fuel tanks installed here, so that they can better achieve the goal of versatility.

The United States is currently bidding on two projects, one using the Sea Harrier's mid-engine layout and the other using the Yak-141's lift fan. They were both successfully led astray! Thinking of this, Qin Tao felt a sense of accomplishment.

At this time, these people began to study it carefully. This was the first time they had observed Dongfang's vertical take-off and landing fighter aircraft at close range. They looked at it very carefully. Zhao Dangsheng on the side kept introducing it.

"Are there only these two nozzles? How to control the attitude during vertical takeoff and landing?"

"We also bleed air from the engine's compressor and blow it to the wing tips for attitude control to avoid crosswinds and other effects," said Zhao Dansheng.

The lift fan at the front and the main engine at the back provide power, and attitude adjustment is performed through the airflow at the wingtips. These controls are very complicated and the pilot cannot take care of them at all. Therefore, advanced aircraft must be used.

control.

Even the Yak-141 was designed to introduce four-degree fly-by-wire flight control. Without the precise control of an electronic computer, it would be impossible to tame this monster. Even so, the pilot's ejection is automatically controlled.

In the event of an accident, the computer will determine at any time whether to eject. There will be no hesitation when it is time to eject, and there will be no decision as to whether to save the aircraft.

At this time, everyone nodded after hearing these introductions.

"Of course, this vertical take-off and landing solution will still have certain risks. However, if compared with the blocked landing solution, we believe that this solution will still be suitable for the actual situation of some countries, such as yours.

"

The danger of vertical takeoff and landing is very high. After the American F-35B was put into service in large quantities, accidents often occurred and even caused the aircraft to crash. The failure rate of this thing is high. As for the Sea Harrier, it is even more likely to crash.

As a master of aircraft, when the US Marine Corps replaced the Sea Harrier with the F-35, a total of more than 300 Sea Harriers had been lost and 110 had been lost.

Now, the Saudi visitors were very excited when they looked at the Transformers-like vertical take-off and landing fighter. They watched it for more than half an hour. Salman asked: "Excuse me, when can we watch its performance?"
