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

Chapter 329: Heaven-Defying Test Flight

Zhao Xiansheng said in shock: "This climbing speed is quite fast!"

"What amazes me most is, can it fly so high?"

If the acceleration is turned on, even for a second-generation aircraft, it would only take a few minutes to reach an altitude of 20,000 meters.

But now, the drone didn't accelerate at all, it just climbed up slowly.

Moreover, generally speaking, there are not many supersonic aircraft that can climb to an altitude of 2 meters.

Now, this unmanned aircraft can actually climb to an altitude of over 2 meters without any effort in one breath?
This is a bit against the will of heaven.

It can climb to an altitude of over 20,000 meters. If the enemy is an ordinary fighter, it will basically be impossible to catch up.

The foot basin now owns two types of fighter jets, F16 and F15.

The maximum ceiling of F16 is only 1.8 meters.

The maximum ceiling of F15 can reach 2 meters.

However, the F15 is a heavy fighter and generally will not be dispatched to perform interception missions.

Moreover, it seems that the drone is still climbing.

It seems that its ceiling should be more than 2 meters!
Wang Haoran smiled and said, "When we designed this aircraft, we positioned it as a high-altitude reconnaissance aircraft."

"So, the ideal ceiling I designed should be around 2.3 meters!"

Li Xuejun stared at the screen and said, "We have now climbed to 2.15 meters!"

"As a drone, this is quite an impressive height."

The oxygen is thin at high altitudes.

Generally speaking, if the engine does not have enough air intake, its power will be greatly affected.

Therefore, being able to fly so high is definitely amazing.

Some people may say that Giant Eagle was able to manufacture the U3 high-altitude reconnaissance aircraft with a ceiling of nearly 2 meters in the s and s!
We still have to admit that there is a gap between us and others.

Things like the U2 with big wings actually have no advantages other than flying higher.

It was also able to prevail for a while in the fifties and sixties.

When anti-aircraft missiles are developed, if it wants to fly over other people's skies unimpeded for reconnaissance, it will just be shot down as a target.

In the 60s, Longguo shot down 6 U2 fighters in succession.

As a result, this so-called most advanced high-altitude reconnaissance aircraft at the time was so frightened that it never dared to come over again.

Zhao Xiansheng's eyes lit up and he said with a smile, "A drone that can fly over 20,000 meters should not be able to be intercepted by any aircraft right now. We can only watch helplessly as it farts from below."

"If this thing flies directly to the sky near the foot basin, the people in the foot basin will probably be pissed to death."

Wang Haoran smiled and said, "I just want to harass them!"

"Let them keep taking off and flying together."

“Let them run wild.”

"It's better to have more accidents."

"That way, they'll be obedient."

The air defense identification area of ​​the foot basin is drawn very large, almost to Long's home.

Bang Bang has a similar character.

These two eagles' slaves are actually slutty bitches.

They regard whoever beats and abuses them as their father.

As they were talking, the WZ-7 had already reached an altitude of over 2 kilometers.

There was an uproar in the monitoring room.

Flying a drone at an altitude of 2.3 meters is absolutely unprecedented.

"It feels like it still has the strength to continue climbing!" Ge Xiaobing murmured.

Before Wang Haoran could say anything, Zhao Xiansheng hurriedly said, "Let's try and see how high it can fly!"

"Its wings are also large enough. I think its maximum ceiling should be more than 2.5 meters, right?"

Li Xuejun smiled and said, "At an altitude of 2.5 meters, it's basically close to outer space, right?"

“Is the plane’s engine still working?”

Wang Haoran nodded and said, "Our engine is a variable cycle engine."

"And it uses a three-module combination technology."

"Plus, our aircraft is made of carbon fiber, so it is light enough."

"So, after flying to an altitude of more than 20,000 meters, there is absolutely no problem with the aircraft engine."

As he spoke, Wang Haoran controlled the plane to continue climbing.

While controlling the plane remotely, he was also observing various parameters of the aircraft.

If he notices something is wrong, he will immediately stop the drone from climbing.

Ge Xiaobing was deeply moved.

Because the performance of the aircraft developed by Wang Haoran is so eye-catching.

Generally speaking, when a new aircraft is tested for the first time, if it can only fly one circle in the air, it is considered a huge success.

However, the aircraft developed by Wang Haoran often have amazing performance during their first test flight.

This drone test flight was extremely difficult from the very beginning.

This is the beginning of seeing what the maximum ceiling is.

Wang Haoran controlled the Wuzhen 7 to climb to an altitude of 2.5 meters.

He could feel that the various parameters of the aircraft were already a bit strained, so he stopped climbing and started flying parallel.

An altitude of 2.5 meters is still considered the stratosphere.

However, the air is even thinner, less than one-fifth of that on the ground.

The Wuzhen-7 was flying steadily at an altitude of 2.5 meters, with a speed of about 300 kilometers per hour.

If this speed were on a train, it would be called lightning speed.

But for an airplane, this is a super slow flight.

Moreover, it is as slow as a snail.

Zhao Xiansheng nodded and said, "Its ability to fly slowly is very good."

"Haoran, you said it can speed up the process, right?"

Wang Haoran smiled and nodded: "Yes!"

"It can increase its maximum speed to over Mach 2."

"And, as long as you step on the accelerator, the speed will increase naturally and smoothly."

Li Xuejun asked: "Is the first test flight so difficult?"

Zhao Xiansheng laughed and said, "Leader, they are just drones."

"Increase the difficulty and see how capable it is."

"We are now a little impatient to equip the troops as soon as possible."

"I think that although this aircraft is a brand new achievement, its stability is still very high!"

Li Xuejun said: "Then let's try to speed up."

"But, Comrade Haoran, you have to be careful. If you find something wrong, you should stop it immediately."

"I still hope that this prototype can land smoothly on the ground."

Wang Haoran smiled and said, "No problem!"

"Although this plane is flying for the first time today, we have tested it a lot on the ground, haha!"

As Wang Haoran spoke, he started to accelerate.

Wuzhen 7 began to accelerate rapidly at an altitude of 2.5 meters.

The acceleration is so fast!
In just twenty or thirty seconds, the speed increased from 300 kilometers per hour to more than 2800 kilometers per hour.

This speed is close to 2.5 times the speed of sound.

Of course, the speed of voice transmission at high altitudes is actually much faster.

On the ground, the speed of sound is 340 meters per second.

But if it is at an altitude of 2.5 meters, the speed of sound becomes more than 100 meters per second.

The speed is rapidly increasing.

It rose all the way to more than 2800 kilometers per hour.

Several big men stared with wide eyes. "Haoran, is this speed real?" Li Xuejun was a little unconvinced.

After all, this is a drone, and it is at an altitude of 2.5 meters, so we cannot measure and confirm it.

Wang Haoran smiled and said, "It's genuine!"

Zhao Xiansheng exclaimed: "It is really shocking that the speed can be quickly converted from ultra-low speed to ultra-high speed."

"Comrade Haoran, how long can it maintain this speed?"

Wang Haoran said: "It shouldn't be a problem to maintain it for an hour."

"The higher the speed, the greater the fuel consumption."

"At this speed, our drone can only fly for a little over two hours at most."

Liu Zengguang nodded and said, "It's already very impressive."

"At an altitude of 2 kilometers, it can reach a speed of nearly 5 kilometers per hour. Who could have imagined that?"

Wang Haoran silently controlled the drone, and he made the drone fly in a large circle over the sparsely populated area.

The prototype flew for more than half an hour at a speed of more than 2800 kilometers.

The flight was very smooth, the engine and everything was working normally.

Wang Haoran started to slow down again.

In one breath, the speed was reduced from nearly 3000 kilometers per hour to 300 kilometers per hour.

The deceleration is also very smooth.

Wang Haoran looked at the fuel and luckily, there was still half of it left.

"Haoran, does this drone have to be watched closely by someone all the time?" Zhao Xiansheng asked again at this time.

Wang Haoran said: "You can set up a program to let it cruise along a fixed route and perform reconnaissance and intelligence gathering tasks."

Ge Xiaobing said: "It looks like there is still a lot of fuel left."

"Can we test other content, such as the stealth function?"

Wang Haoran smiled and said, "The area around the capital is the most densely populated by radars!"

"These radars are responsible for guarding the capital."

“They’re working all the time.”

"Even though we have already reported this flight."

"But if these radars detect an aircraft, they will definitely issue a warning."

"How about asking those radar stations and finding out what they are like and what the situation is?"

Li Xuejun immediately gave an order.

Soon, information from surrounding radar stations all came in.

"No trace of the test drone was found!"

"The test drone never showed up on the radar screen!"

Li Xuejun scratched his head and laughed, saying, "This is incredible!"

“This is simply amazing!”

"Our radar station in the suburbs of Beijing has a meter-wave radar!"

"Damn it! Doesn't this mean that our spears have pierced our own shields?"

Wang Haoran smiled and said, "You can understand it this way for now."

"The stealth skin we developed has relatively strong performance."

"But if you want to detect stealth aircraft, relying solely on radar is definitely not enough."

"We still have to rely on a large number of satellites in space!"

"Besides, our radar, with a slight upgrade, will probably be able to detect our own stealth drones."

Zhao Xiansheng rubbed his hands excitedly and said, "This invisibility function is really great! Haha!"

"I can't wait to take delivery of this aircraft."

"Also, I hope to be able to make other fighter planes stealth-proof."

"In this way, all our fighter jets will have stealth capabilities."

"Wouldn't that mean that our air force's combat capability could be greatly improved quickly?"

Wang Haoran smiled and said, "Comrade Xiansheng, stealth fighters can achieve stealth by more than just applying stealth skin."

"Invisibility is an all-round design."

"If we don't adopt a stealth design, then we can't actually achieve the stealth effect, haha!"

Feng Mingxin hurriedly said, "Comrade Haoran already has a design for a stealth fighter."

"I have heard him speak of it in detail."

"If he can really make this kind of plane, it will be absolutely amazing!"

Zhao Xiansheng nodded thoughtfully and said, "Oh...it turns out that Comrade Haoran is also developing a stealth fighter!"

"In fact, Chengfei and Shenfei are also doing this."

"I originally wanted you to get together."

Shen Fei and Cheng Fei are considered the most beloved sons of the Air Force.

Of course, the Air Force cannot control these two major aircraft factories on its own.

Ge Xiaobing spoke frankly and said, "Leader, let me say that those two haven't even figured out the shadow of a stealth fighter, right?"

"I guess they just took a look at the Giant Eagle's F117 and started to imitate it, right?"

“But there are no blueprints, let alone the opportunity for reverse engineering.”

"Putting hope on them is the most unreliable thing in my opinion."

Zhao Xiansheng laughed and said, "That makes sense!"

“In fact, we are not against competition.”

"No matter which company comes up with the product, we welcome it very much!"

"Are you comrades from Xi'an Aircraft Industry planning to work with Comrade Haoran to develop a fifth-generation aircraft?"

Feng Mingxin felt a little embarrassed and quickly said, "We also want to help the country."

"As soon as Comrade Haoran talked about his fifth-generation aircraft plan, I agreed with it very much."

"I think we must help him develop the stealth fighter as soon as possible."

Li Xuejun said: "You are flying west, you actually have a lot of tasks now, right?"

"My suggestion is that you can participate in the development of the fifth-generation stealth fighter!"

"However, when mass production begins in the future, I'm afraid other aircraft manufacturers will have to take over a large portion of the tasks."

Feng Mingxin puffed out his chest and said, "No problem!"

"We will absolutely obey the organization's arrangements!"

"For example, the J-10 was originally developed by us with the assistance of Comrade Haoran, but now when it is put into production, it is also distributed to brother units for joint production."

Zhao Xiansheng nodded appreciatively and said, "This attitude is definitely worthy of praise!"

"We want the whole country to play as one!"

"Later, I also want to hear Comrade Haoran's introduction to the fifth-generation stealth fighter."

Wang Haoran smiled and said, "Absolutely no problem."

The first WZ-7 prototype flew in the air for more than two hours and carried out almost all the tests.

The test results were quite good.

Finally, the drone landed on the runway at the test flight range.

When the plane stopped and the engine was turned off, Zhao Xiansheng couldn't wait to walk over.

Others gathered around as well.

Wang Haoran first took the team to check the plane.

We have just demonstrated supersonic penetration at high altitude, so the first thing to check must be whether the outer skin of the aircraft is damaged.

The results of the inspection were very good.

The skin is intact, which shows that the bonding is quite firm.

The engine was then inspected.

It is a big taboo to change speed while the engine is running and the key components change their position and shape!
Therefore, check to see if there are any loose parts in the engine.
