At last year's air show, Han used the vertical take-off and landing fighter for the flight performance. After all, when this aircraft was publicized, it was one aircraft type 3. Everyone knows that it must be the most difficult vertical take-off and landing. As long as this technology is solved, other technologies will not be a problem.

Spee doesn't know how many times he has studied the video of the air show. After all, they want to engage in vertical takeoff and landing fighters. The takeoff and landing of aircraft is the most critical. The transformation of horizontal and vertical is the top priority. Once something goes wrong, something must happen to this project.

As for the normal flight, there is not much brilliance.

Now, seeing this normal take-off and landing aircraft, they finally found something unusual. The tail nozzle is different!

For VTOL fighters, the tail nozzle uses a three-stage rotation mode, which can convert from downward jet to backward jet. This nozzle cannot become an omni-directional vectoring nozzle. Therefore, in conventional air maneuvers, VTOL aircraft mainly rely on strong engine thrust.

Now, this conventional model adds an omni-directional vectoring nozzle at the tail, which immediately improves its mobility. Although this aircraft is very fat, it may be able to surpass its opponent in mobility by fighting with the third generation aircraft in air combat!

How rebellious the Han people are!

Many manufacturers are developing the vectoring nozzle of the engine. The simplest form is the baffle. Adding a baffle behind the engine can change the jet air flow, so that the air flow is not all backward, and the separated air flow can provide thrust in other directions, so as to give the aircraft a vector maneuver.

Their F22 fighters use this technology to change the air flow by means of baffles.

What is more advanced than the baffle is that the whole tail nozzle can rotate. When the tail nozzle rotates, it can change the direction of the sprayed air flow. It can deflect in all directions, so it has the ability of omni-directional vector propulsion.

The other party just deflected in the horizontal direction!

With this, the maneuverability of the aircraft can be improved to a higher level.

However, the technical difficulty of this nozzle is very great. How to move and seal the scales behind is a difficult problem. After all, the temperature there is not low. How did the Han people do it?

The more spee looked, the more he felt that there was a big gap with the Han people. Now, the plane was roaring and landing from their eyes.

The four planes landed together. In this way, it was even more spectacular, and it was even more surprised to see spee in front of him.

In order to get out quickly, fighters can take off in formation. Both two planes and four planes are normal. The Eagle Air Force often plays like this. However, they have never landed in formation. This is not fun. The risk of landing is far greater than that of taking off. They must have installed advanced flight control systems on the aircraft, or even, In fact, this kind of aircraft is automatically controlled. They pilots can complete the formation landing process without touching the joystick.

Compared with the appearance, stealth capability, vertical takeoff and landing capability, the technology of the Han country is the most advanced. In fact, it is this electronic capability. Their flight control system is a generation ahead of the eagle country. Maybe it is optical fiber transmission?

"Stop, stop, stop!" spee shouted as if he had found something.

After the other party landed, he didn't stop and waited for general Jamal and others to see. Instead, he continued to slide and glided towards the hangar. In this way, he had to close the door directly to thank the passengers!

They tried very hard to come here to see this kind of plane. As a result, people showed it in front of them and then entered the hangar. Is that good?

You've gone too far. Look at your plane. It won't fall. What are you afraid of?

"Hey, what's going on?" even General David felt wronged. Are you fooling us? Right in front of us, pass the field at low altitude. After landing, directly enter the hangar?

Later, it was announced that after the plane came, it was shown to us. Yes, we did, but what's the difference between not seeing it?

Even if you don't let me sit up, at least have a close look and touch?

General David's face was full of displeasure. At this time, major general hasMy introduced to you: "I'm sorry, please understand. Our aircraft is in combat. The surface of the aircraft is sprayed with stealth coating. This coating is quite delicate. Therefore, after landing, you must immediately enter the hangar with constant temperature and humidity for maintenance. You are experts and should know."

Spee nodded when he heard this. Yes, it's right. So is the plane developed by their skunk factory.

Take a look at the planes of the Xiong Kingdom and the MIG series fighters. They all have to adapt to the field deployment. Even if it's windy and rainy, the most is to tie a piece of cloth on the cockpit cover. Others don't care at all. The same is true of the fighters of the Han kingdom in the early years. The planes in the base are parked in the open air. Later, they didn't start to build a simple hangar until there are three generations of planes.

To say that this kind of constant temperature and humidity hangar is extremely luxurious, but there is no way. After all, this is the fourth generation aircraft. An important feature of the fourth generation aircraft is stealth. In addition to the appearance, it has a great relationship with the coating. The coating will wear after each flight and needs to be maintained.

Otherwise, the aircraft will lose its original characteristics. In this way, the operation cost of the fourth generation aircraft will be greatly increased. If the on-site maintenance personnel can't master the technical essentials and ask the factory technicians to carry out maintenance, the expenditure will be even more outrageous.

This is also the reason why it is impossible for the fourth generation to expand in a large area, and poor countries can't afford it.

"Well, can we go into the hangar and have a look?" spee asked the crowd.

"We'll go to dinner first, and then we'll go after dinner and after the maintenance," said general Jamal.

How to maintain the surface coating is also a secret, especially the process. It is impossible for the other party to see. Spee was very dissatisfied with such a proposal, but there was no other way. He could only nod and go to dinner with him.

When they wait at the dinner table, they are even more annoyed when they look at the authentic Chinese dishes. People entertain Han guests. They come uninvited and don't consider their eating habits at all.

However, the dishes of the Han Dynasty taste pretty good.
