The rejuvenation of a great nation: from educated youth to national treasure scientist

Giant Eagle is the world's first supergiant to develop stealth materials.

It began experimenting with using stealth technology on reconnaissance aircraft as early as the 1950s.

In 1953, when developing a new reconnaissance aircraft, Eagle put forward the design requirement of minimizing the possibility of being detected by the enemy radar.

As early as the 50s, the U-2 high-altitude reconnaissance aircraft used radar-absorbing paint, which was also the first application of radar-absorbing paint in the world.

By the end of the 60s, the B-1A strategic bomber of the Eagle adopted low-detectability hormones such as wing-body fusion shape and radar-absorbing materials. This is also a further development of fighter stealth technology.

By the mid-70s, electromagnetic theory and electronic industry capabilities had made great progress, and the world's first truly stealth fighter, the F-117 stealth fighter and the B-2 stealth strategic bomber, heralded a major breakthrough in stealth fighter technology.

However, it should be pointed out that the Eagle's stealth material is very difficult to maintain.

For example, the stealth coating used on the F-22 fighter has excellent stealth effect.

However, it is very easy to peel off, and maintenance is quite complicated and time-consuming, with a large workload, and requires special maintenance equipment and environment.

Every time the F-22 performs a mission, it needs to be repainted with stealth materials for maintenance when it returns.

Because the F22's stealth coating will crack and fall off after multiple supersonic flights.

This is mainly because the F22's coating is composed of multiple layers of paint and the maintenance process is too complicated.

For example, the F22's air intake requires 341 man-hours to strip all the coatings.

The repair took 3853 hours.

This is also why the F22 has a relatively short mission execution time.

The poor F22 is either undergoing maintenance or on its way to a special air-conditioned hangar for servicing.

This greatly weakened its combat effectiveness.

Wang Haoran doesn't want to follow Eagle's old path.

He felt that since they were going to make a stealth fighter, it would be better to develop better stealth coating materials.

In the previous life, Northwestern Polytechnical University developed stealth skin.

The full name of this thing is "Multi-spectral Stealth Skin and Its Adaptive System".

The fighter jet's radar-absorbing stealth capabilities can be integrated into the skin.

Stealth skin can solve almost all the shortcomings of traditional radar-absorbing coatings and greatly improve stealth performance.

And it is quite easy to maintain.

Most importantly, it can absorb radar waves with a wider frequency, and it can even absorb meter-wave radar.

As we all know, meter-wave radar is known as the killer of stealth fighters.

Another thing is that the thickness of the stealth skin's radar-absorbing coating is only 0.2 mm.

The Eagle's stealth absorbing coating is 2 centimeters thick.

This can significantly reduce the weight of stealth fighter jets.

After all, the stealth paint used by the Eagle is quite heavy.

The stealth coating used on the F22 weighs more than 3 kilograms per square meter.

The painting area of ​​a fighter jet can reach 6 to square meters, and the added weight can reach up to kilograms.

The stealth skin also has properties such as high strength and high temperature resistance.

It is countless times more powerful than stealth paint.

Wang Haoran decided that if he was going to do it, he would do the best he could and just do it in one go.

After Wang Haoran came up with the overall design plan for the drone's aerodynamic layout and appearance, he broke down the tasks and assigned each team member to a part.

After they built the model, they sent it to the wind tunnel to blow it.

If problems are found after blowing, adjustments and modifications will be made.

After the modification, go to the wind tunnel.

Soon, the shape of the drone was determined.

This is the benefit of having complete wind tunnel facilities.

Without a good wind tunnel, there will be no good aerodynamic layout.

Without a good aerodynamic layout, even if a fighter jet is built, it is likely to have various deficiencies in a real flight environment.

Once the aerodynamic layout and appearance are determined, everything will be easy.

Pangu Technology is wealthy and has a complete range of mechanical equipment, so it will be no problem for it to build a prototype.

After more than three months of hard work, in September 1986, the first prototype of the WZ-9 was finally built.

This drone uses a very rare diamond-shaped wing design.

This can give the Wuzhen 7 better lift characteristics when flying.

Moreover, the diamond-shaped wings also allow the drone to fly at a faster speed.

In addition, it adopts a conventional double tail support layout, with the side wings connected to the main wing. This also makes the Wuzhen 7 more stable when flying at high speed.

Its fuselage design adopts a non-mainstream connected wing layout, with the wings swept back and the tail swept forward. It is connected and fixed vertically with rigidity, which greatly improves the strength and stability of the fuselage.

Its fuselage is mainly made of carbon fiber composite materials and uses stealth wave-absorbing skin, and its stealth performance is first-class.

In addition to its eye-catching appearance, its engine is also very exciting.

It uses the first truly variable cycle engine in Longguo and even in the world.

This also allows the WZ-7 to combine slow cruising with high-speed penetration.

After the prototype was made, Wang Haoran called the designer immediately.

The designer was very excited when he heard it.

Because Longguo really needs a reconnaissance drone with long range and long cruising time.

In this respect, both eagles and bears have it.

The leader encouraged Wang Haoran and said, "You guys test it first."

“After the test is successful, if there are no problems, then we will promote it as soon as possible.”

"It was the Eagles that had been harassing us non-stop with their reconnaissance aircraft."

"Now, let's let them taste this pain, haha!"

"Well! You guys should work with the Air Force and let them conduct the test."

"Now that we have an aircraft carrier, in principle, it is possible to get this thing on an aircraft carrier in the future."

"Then let the navy get involved as well."

"It would be best if you choose another aircraft manufacturer to cooperate with and combine forces as soon as possible."

Wang Haoran naturally agreed.

After finishing the call with his boss, Wang Haoran made another round of calls.

I first called Li Xuejun, the head of the Longguo military, to report this achievement.

After all, this drone was a project directly initiated by the military.

And Li Xuejun also gave him a lot of support.

When Li Xuejun heard that the long-range unmanned reconnaissance aircraft had actually produced some results, he was also very excited.

He said he wanted to come and see it himself.

Of course, he would bring the heads of the navy and air force with him.

The two parties agreed to meet the next afternoon.

Wang Haoran called Xi'an Aircraft Industrial Corporation's director Feng Mingxin again.

It is precisely because of Wang Haoran’s support and help that Xi’an Aircraft Industry Corporation has developed very well in recent years.

Some of the J-10 aircraft were produced at Xi'an Aircraft Industrial Corporation.

In addition, Xi'an Aircraft Industrial Corporation has also developed better bombers such as the H-6K with longer combat radius and better avionics systems.

Even the electronic warfare aircraft is manufactured by Xi'an Aircraft Industry Corporation.

At present, Xi'an Aircraft Industrial Corporation is already showing signs of surpassing Shenyang Aircraft Corporation.

Shenfei is the big brother of the aviation industry and the best aircraft manufacturer in the country.

Feng Mingxin was very happy after listening to Wang Haoran's introduction.

A long-flight reconnaissance drone has come out so soon?

Moreover, this plane seems to have a lot of black technology!
It would be great if we could get Xi'an Aircraft Industrial Corporation to manufacture it.

Of course, Feng Mingxin also knew that the country would conduct unified regulation.

We can’t let Xifei’s family eat too much.

Then, the other aircraft manufacturers went hungry.

This is definitely not possible.

For example, the manufacturing of the J-10, although Xi'an Aircraft Industry Corporation is now the main force, it has also been assigned a considerable part of the task. In addition, Shenyang Aircraft Corporation has also built the J-16 heavy fighter and the J-11 fighter with the help of Wang Haoran.

Of course, the J-16 heavy fighter is also very powerful.

This fighter has now become the main heavy fighter of the Longguo Air Force.

After Feng Mingxin received Wang Haoran's call, he and chief engineer Ge Xiaobing immediately boarded a domestically produced Starship passenger plane to Pangu Technology Company in Beijing.

Along the way, he also discussed with Ge Xiaobing whether this large unmanned reconnaissance aircraft could receive key support for development.

Feng Mingxin believes that the country currently lacks a truly advanced large-scale military reconnaissance drone.

As long as the performance of this new drone developed by Wang Haoran is truly outstanding, the country will certainly fully support the mass production of the equipment.

After all, the territory of Dragon Country is huge.

A large number of long-flight unmanned reconnaissance aircraft are needed to patrol border areas.

In coastal areas, the challenges faced by Longguo are even more severe.

Unmanned reconnaissance aircraft are also needed to conduct all-round reconnaissance and control of complex sea areas.

However, Ge Xiaobing feels that Longguo already has the KJ series of aircraft and the Y-8 modified reconnaissance aircraft.

There is actually not much necessity to develop unmanned reconnaissance aircraft.

Therefore, Ge Xiaobing is not optimistic about the development of this large unmanned reconnaissance aircraft developed by Wang Haoran.

The two of them argued all the way to the capital.

When they arrived in Beijing, it was already past 8 o'clock in the evening.

However, they were still welcomed by Pangu Technology.

The people from Pangu Technology also arranged for them to stay in the company's guesthouse.

The next morning, Feng Mingxin and Ge Xiaobing couldn't wait to come to Pangu Technology Company's large test workshop.

This workshop once developed turbofan engines for aircraft.

Wang Haoran was already waiting for them there.

As soon as they met, Wang Haoran shook hands and greeted Feng Mingxin warmly.

"Comrade Haoran, long time no see! Haha!"

Wang Haoran smiled and said, "Yes, everyone is busy, so it's not easy to meet each other, haha!"

"NWPU hired me as a visiting professor and invited me to give them lectures and stuff."

"I can't even fulfill this obligation, haha!"

Feng Mingxin said: "You have a heavy responsibility on your shoulders."

“You have to manage a business, do scientific research, and provide some on-site guidance.”

“I believe that students at NWPU can understand you.”

After the greetings, Wang Haoran took them to see Black Panther 7.

After seeing the appearance of the new plane, Feng Mingxin and Ge Xiaobing were both surprised.

Because this broke the two people's imagination of large drones.

Whether it's the Eagle or the Bear, their large drones actually still look like traditional aircraft.

Xiong's large drone is simply modified from the large aircraft in the Tu series.

But now, what the hell is this thing in front of me?

It still looks like an airplane.

And it looks quite large, but isn’t the shape too weird?

It even feels a bit ugly.

This……

Could Wang Haoran actually come up with such a thing?

Wang Haoran looked at the two people and said with a smile, "Are you two a little disappointed?"

"This drone is definitely different from a manned aircraft."

"The shape of the fuselage is designed like this mainly to make it stronger."

Ge Xiaobing hesitated for a moment and said, "Is the performance of this thing guaranteed?"

Wang Haoran smiled and said, "I haven't tried it yet."

"But its aerodynamic shape and layout were actually developed in the wind tunnel."

"Personally, I think it should be pretty good, right?"

Wang Haoran introduced the test results of the aircraft to the two of them.

The radar stealth effect is still good, and it can absorb and dissolve very wide-band electromagnetic waves.

Ultimately achieving the effect of radar stealth.

Stealth aircraft?

Feng Mingxin was immediately a little excited.

Because the publicity for Eagle's F117 is really overwhelming now!
The Eagles are about to hype up their F117 as an invincible and unstoppable weapon.

The most important selling point of F117 is stealth!
It is known as the invisible black hole.

If it is deployed at night, the radar will basically have no response to it.

The Eagle also boasted that it often sent F117s to fly over the Giant Bear's territory to show off.

And the giant bear never noticed.

Eagle also said that he often used this thing to tease the dragon.

"Comrade Haoran, I didn't expect that you have mastered the stealth technology?" Feng Mingxin said with surprise.

Wang Haoran smiled and said, "Invisibility technology is actually not that great."

"I'm not bragging, but the stealth performance of the Eagle's F117 is nothing compared to our aircraft!"

Ge Xiaobing walked forward carefully and checked it cautiously.

He wanted to see the stealth coating of the strange aircraft in front of him.

Because, according to Eagle's self-boasting, the reason why the F117 has such a good stealth effect is because it uses very advanced stealth absorbing materials.

This material is very expensive, more expensive than gold.

Ge Xiaobing looked over and over, but he didn't know whether the dark paint on the plane was a radar-absorbing material.

However, according to common sense, if the absorbing material is to achieve the absorbing effect, it should not be too thin, right?

Ge Xiaobing said: "Comrade Haoran, how did we get this radar absorbing paint on?"

"It feels different from the spy photos of the Eagle F117 we saw."

Wang Haoran explained with a smile: "Actually, we just stick it on directly."

Ge Xiaobing was surprised: "Is it pasted there?"

"Can I touch it with my hands?"

Wang Haoran smiled and nodded: "Of course no problem."

"We call this a stealth skin!"

“This is a more intuitive name, but it actually involves a very complex technical integration.”

"It might be more appropriate to call it 'Multi-spectral Stealth Skin and Its Adaptive System'..."

Wang Haoran began to explain the technology of the stealth skin.

His introduction was simple and clear.

Feng Mingxin and Ge Xiaobing nodded repeatedly after hearing this.

"Comrade Haoran, have you tested its radar absorbing effect?" Ge Xiaobing asked.

Wang Haoran nodded and said, "That's right."

“We’ve done a lot of testing.”

"Generally speaking, this absorber can absorb a wide range of radar waves. Even meter-wave radars may be absorbed..."

"Let's test it out."

Wang Haoran started testing.

There are multiple models of radars available for testing on site.

After testing, it can be clearly seen that this drone has no display on the radar screen interface at all.

This made Ge Xiaobing amazed.

He suddenly thought of something... (End of this chapter)
