A big country of aerospace with black technology

The joint cruise is very big, at least in this area of ​​the Northwest Pacific, it is eye-catching.

As soon as the two warships entered the Tsushima Strait, they attracted most of the attention of several countries in the area.

Especially the two countries on both sides of the strait.

It's like a mouse meeting a cat.

Like facing a formidable enemy!

They all sent their main warships to follow and monitor.

For a time, warships gathered in the corner of the ocean.

Thousands of tons of steel create white waves on the blue sea.

However, in fact, this level of cruising will not cause any particularly big disputes.

After all, the relationship between the relevant forces behind it has been pretty good recently.

"It will rewrite future wars."

Zhang Xingyang excitedly touched the landing gear of a huge airplane on the field and said.

"Really?"

The accompanying visitors didn't see much of how this thing could change future wars.

Although its shape looks very sci-fi.

It has huge tilted delta wings.

There are several large serrations at the rear to reduce the radar reflection area.

Its engine system is also more special.

Because the combat altitude is much higher than the original bombers, fighter jets, etc.

So, it actually has two different engine systems.

Aero-engine systems designed to operate in the lower atmosphere.

and rocket engine systems used to operate in the upper atmosphere.

Mainly because the oxygen is thin at high altitudes, if rocket engines are not used.

The oxidizer problem of aircraft engines is a huge problem.

All kinds of advanced technologies have been applied to this bomber that has just been debugged.

Therefore, this bomber is very technologically advanced.

But it's also very dangerous.

The advancement of technology also brings instability problems.

With so many advanced technologies, it is foreseeable that the stability of a stacked bomber will not be very high.

"For this test flight, we just need serious flight performance."

Zhang Xingyang made a few special remarks before the test pilot boarded the plane.

The test pilot for this test flight was different from the previous fighter jets.

Because such a large bomber cannot be flown by one person.

So, this time it's a whole crew.

Four people in total.

Compared with the H-6, which is currently the main force in the country, the number of crew members is already very small.

"No matter how the test flight goes, I hope to see you back safely."

Zhang Xingyang said very calmly:

"If you encounter a major problem, just parachute out."

"Our escape system is the latest development and can complete ejection in the shortest time to ensure your safety!"

"If the bomber is broken, we can still assemble it again, but it is too difficult to train good test pilots once they are lost."

At this time, the domestic situation was actually very different from when Zhang Xingyang and Song Tianxing flew the J-10 a few years ago.

The development of the past ten years has brought about more than just economic take-off.

There are also rapid developments in various technologies.

All these have led to the training of a group of crews capable of conducting bomber test flights.

Weighing their weight in gold, they are considered cheap.

"Report to the Commander-in-Chief, we will resolutely complete the test flight mission!"

The test flight crew was very confident and said with great ambition.

"Then I wish you a triumphant return!"

After saying that, the four people saluted directly to everyone present and trotted into the bomber.

This suborbital bomber is very large, with a wingspan of nearly 80 meters.

It's a real behemoth.

Crew members need to enter the fuselage through the telescopic ladder under the belly.

"Do you think the success rate of this test flight is high?"

The old leader who was specially invited to visit asked Zhang Xingyang in a low voice after the crew members boarded the bomber.

"They may not be particularly familiar with the internal equipment, but it's not a big problem."

Zhang Xingyang looked at the slowly gliding bomber and frowned:

"If there is any problem, the intelligent management system on board can actually handle it simply.

If it cannot be handled, it will be sent to the equipment station for crew members to handle. "

After hearing this, the old chief felt relieved and nodded without saying anything more.

This suborbital bomber weighs a lot, with a maximum take-off weight of 210 tons.

The normal bomb load is 20 tons.

It uses an internal magazine and can have many different layouts.

Applicable to missiles of different sizes.

Because the strategy of using suborbital bombers will be to stealthly penetrate into the enemy's deep territory at high altitudes and carry out bombing missions on strategic locations.

Therefore, what it can carry will basically be long-range missiles.

Six powerful aero engines spit out dark blue flames at a speed visible to the naked eye.

Pushing the extremely heavy fuselage to taxi on the runway.

During the first test flight, no missiles were loaded.

So the take-off weight has been reduced.

But even so, it still taxied for more than 1,300 meters before slowly taking off from the runway.

The bomber with gray and black stealth paint looks like a huge roc.

After taking off from the airport runway, it shot straight into the sky.

After circling for several times, I found that the bomber itself seemed to have no obvious problems.

The first and most important test began.

That is the flight altitude test.

Known as a suborbital bomber.

Of course, at least it must be able to fly to suborbital altitude.

Otherwise, just call the atmospheric bombers.

The suborbital altitude is at least 80 kilometers or even 120 kilometers.

Of course, everyone did not set such high standards for the first test flight.

Just fly over an altitude of 80 kilometers and reach the top of the mesosphere.

"Do you think we can successfully fly to an altitude of 80 kilometers this time?"

The old chief asked in a rather calm tone.

His question was also the voice of everyone present.

This value is really scary.

Prior to this, the height limit for jet fighters was 36,400 meters set by the MiG-25.

That’s a little over 36 kilometers.

This does not mean that the fighter jet’s engine can no longer fly.

It is true that the oxygen in high altitude is too thin.

The engine thrust dropped dramatically.

After all, whether it is a turboprop, turbojet, or turbofan engine, air is compressed by a compressor to act as an oxidizer.

When oxygen is thin, there is no oxidizing agent.

Without oxidizer, there is no thrust.

Without thrust, it cannot continue to rise.

So this altitude is almost the limit of a jet aircraft.

"Whether it can reach an altitude of 80,000 meters depends on whether the flight switching system we designed can work."

Zhang Xingyang said looking at the sky with only clouds left.

Looking at the data next to it, I saw that the height of the bomber was almost rising in a straight line.

It has now reached an altitude of 20,000 meters.

This is already the height limit for ordinary fighter jets.

“Victory or defeat is here.”

Everyone present was a little nervous.

At this time, it was almost time for the rocket propulsion system to work.

The solid rocket motor will continue to push the aircraft upward!

The total nitrogen anion salt is burning fiercely in the rocket engine combustion chamber.

Then the bomber's tail spit out orange flames several meters long.

The bomber jumped upwards as if someone had kicked it.

The test pilots on the crew had already undergone detailed training during previous training.

This sudden feeling of pushing back is still a bit difficult for everyone to adapt to.

Because no one expected that this acceleration would come so fast!

The overload reached 7 G almost instantly.

If they hadn't all been wearing anti-gravity suits similar to spacesuits.

And a lot of anti-overload training was carried out on the ground.

I'm not sure now, I've already fainted.

Especially since the plane tilted so much, red vision appeared in both eyes almost instantly.

Fortunately, everyone still overcame many difficulties.

Continue to drive this experimental bomber towards high altitude.

"We have flown over the 40,000-meter altitude line, and we have passed the first difficult time."

It wasn't just Zhang Xingyang who saw the plane at such a height.

Everyone present breathed a sigh of relief.

There are no problems in this process.

The next step is not that difficult.

"However, after passing the stratosphere, the atmospheric conditions will be much worse. It is still quite a challenge to reach the top of the mesosphere."

Zhang Xingyang looked at the rising bombers and poured cold water on everyone.

The higher you go up into the atmosphere, the cooler the temperature becomes.

At the top of the mesosphere, the temperature is about eighty degrees below zero.

This is a major test for any mechanical creation.

The crew members on the bomber felt like they were going through an icy hell.

On the porthole of the cabin, one can see ice flowers forming on the exterior windows.

If the altimeter hadn't reminded them, the plane would still be rising.

Everyone must think that they are now heading towards a sea of ​​ice.

And it is constantly sinking.

Everyone wears an oxygen mask to give their lungs enough oxygen.

At such a high altitude, the oxygen concentration in the atmosphere is no longer enough for people to survive.

"Report to the Commander-in-Chief that Ghost 1 has reached the predetermined height, please ask for further instructions!"

Soon, their voices came from the airwaves tens of thousands of meters high.

"The next step is to test the radar stealth capability."

Zhang Xingyang issued the next task.

The suborbital bomber was named the Phantom for an important reason.

It comes from its stealth ability.

It can hide itself in the ionosphere.

First test whether the ground radar can detect it.

Ground radar uses long waves, although the detection range is relatively long.

But for flying objects at an altitude of tens of kilometers, it actually doesn’t have very good resolution capabilities.

Found after testing.

The radar reflection area of ​​Ghost 1 is not even 0.1 square meters!

You know, its size is much larger than the previous J-20 or Wu Gong-1!

The body length is more than sixty meters, and the wingspan is nearly eighty meters!

Let’s put it this way, the size of a suborbital bomber is more than ten times the size of the J-20!

The body size is ten times larger, but the radar reflection area is very similar.

Mainly because of the advantages of height and appearance design.

The large delta wing design has a very small radar reflection area.

"Did you feel any discomfort during the flight?"

Before issuing the order, Zhang Xingyang asked another question that was not related to the bomber itself.

"Reporting to the command center, we are feeling fine."

After this, the other party obviously hesitated:

"It's just that your blood flow seems to be faster when flying at high altitudes?"

"I don't know if it's an illusion."

Zhang Xingyang glanced at the screen in the command center.

One of the screens displays the personal physiological health data of four people.

The high-altitude suits they wear can monitor health data in real time.

And through data links, it is transmitted to the ground at all times.

After taking a look, Zhang Xingyang was not a doctor or a physiologist.

But it can also be seen that these data do not seem to be so normal.

Especially the heart rate, blood oxygen and other data are much higher than normal.

"Don't worry too much, because you are breathing pure oxygen now."

Zhang Xingyang quickly came to his senses and comforted him gently.

"Once you get back to the ground, you should be back to normal."

"Thank you, Commander Zhang."

After the other party thanked him, he ended the call.

"Where's our doctor?"

Zhang Xingyang frowned and looked at the assistant aside:

"Go and call a doctor."

"Most of the doctors are still on standby in the infirmary and on the airport runway. I'll call them right away!"

With that said, a young man ran out of the command center.

"Is their health value abnormal?"

Looking at Zhang Xingyang, who was frowning, the old chief couldn't help but ask.

"It's not necessarily caused by the high-altitude environment. Maybe they are not suitable for breathing pure oxygen in this environment."

Zhang Xingyang said while thinking about his little knowledge of human biology.

In fact, when conducting manned spaceflight, whether it is a manned spacecraft or a space station.

What is used is not pure oxygen, but mixed oxygen.

Just to prevent someone from getting oxygen drunk.

But this high-altitude environment is different from space.

At this time, even the well-informed Zhang Xingyang was a little unsure.

Not to mention other people.

"Report to the commander-in-chief, the medical team Chen Weimin is here to report."

A military doctor in a blue military uniform shouted breathlessly.

"Stop talking nonsense, come and take a look at their vital signs data. Are there any questions?"

Zhang Xingyang asked him directly to walk to the screen.

Chen Weimin breathed a sigh of relief and stared at the screen closely.

A few minutes later, he raised his head in the eyes of all the big guys.

He said with some confusion: "It seems to be somewhat similar to the situation that occurred during our previous high-altitude endurance training."

"Tell me more carefully?" Zhang Xingyang asked.

At this time, the bomber was conducting long-range flight experiments.

The scheduled flight distance is 10,000 kilometers.

They now have a lot of time to listen to what is going on.

Chen Weimin thought about the wording:

"Actually, this is also related to the physiological limits of the human body."
