The military-industrial scientific research system of the academic master

These discussions either took place in cyberspace or across the ocean, but have not yet reached Chang Haonan's ears.

After confirming the missile hit situation early on New Year's Day, he returned to Haojing without stopping, completed a report as quickly as possible, and then flew directly to the capital.

Of course, in reality, it doesn't matter if you know.

The targets at the Longyuan Effect Range were indeed camouflaged during the construction process, but the traces after being hit would not be able to escape subsequent satellite reconnaissance.

Even if other confidentiality work is perfect, the United States will notice this anomaly by this evening at the latest.

What's more, in the 21st century, perfect confidentiality is simply impossible to exist.

So this kind of thing is like Dayu's control of floods.

The key is to be sparse, not blocked.

Therefore, preparations for this were actually made at the beginning of the planning of the hypersonic verification missile...

…

January 29, 2006, the first day of the Lunar New Year.

Beijing, evening.

It’s still Jingxi Hotel, it’s still that small conference room.

However, the situation is not the same as it was more than a year ago.

This time, when Chang Haonan walked in under the guidance of the staff, he found that the seats inside were almost full.

Even several senior leaders.

Obviously waiting for him.

"Comrade Haonan."

The chief sitting on the sofa in the middle showed a kind smile, without any trace of his past illustrious reputation:

"Since last night, we have been waiting for the good news you brought!"

Faced with this scene, Chang Haonan quickly stepped onto the podium:

"I'm really sorry. Due to the weather conditions at the shooting range, the helicopter took a long detour to ensure safety, so it was a little late."

As he spoke, he motioned to the staff next to him to start operating the equipment and prepare to project the report onto the screen.

In fact, there is no problem with the meteorological conditions at the shooting range.

The helicopter did not take a detour.

In fact, Chang Haonan was not late at all.

But you can't say it's the leader's fault. You shouldn't have come so early, right?

So it can only be pushed to force majeure.

This way everyone can get along with themselves.

Sure enough, the chief waved his hand to show that he didn't care:

"Good things come true in the end. As long as the result is good, why not wait a little longer?"

With one sentence, the originally tense atmosphere immediately relaxed.

At this time, the cover of his report appeared on the curtain behind Chang Haonan.

"Then leaders, let me report on the final results of this hypersonic verification projectile test launch..."

The content of the paper documents submitted for archiving must naturally be rigorous and detailed.

Chang Haonan had already completed the general framework even before the test. In the few hours during the day today, he just filled in some more specific content.

The entire report is quite long, nearly seventy pages.

But these high-level leaders in front of them are dealing with many things every day, and it is obviously impossible to start from the beginning of Pangu.

So as soon as Chang Haonan came up, he released a picture of the missile exiting the cabin.

It was taken by a camera installed on the side of the bomb bay of Figure 41175.

The angle of view is slightly overhead, and you can even vaguely see the lights of thousands of houses in the city in the distance.

The one in the center of the picture is the missile that had just left the launcher but had not yet ignited.

"First of all, during the missile launch process, we successfully proved that the spoiler + trailing edge slope design can significantly improve the air flow under the shallow cavity bomb bay."

As he introduced it, he showed several subsequent screenshots in succession.

Although it is not a continuous video, the entire launch process can be clearly understood very intuitively:

"After the verification bomb was pushed away from the pylon, it only showed a small longitudinal swing. Before the final ignition, it was in an attitude of about 10° elevation, which is just conducive to exerting the longest range of most missiles. This technology The same principle can be applied to the bomb bay of stealth fighter jets to ensure that smaller airborne weapons do not lose attitude control during supersonic departure..."

The opening was so heavy-handed that it obviously caused some commotion in the audience below.

But the chief did not speak in a hurry, but signaled Chang Haonan to continue.

"The subsequent accelerated climb process, except for a certain initial velocity and altitude, is not much different from the ballistic missiles we have seen in the past. It is just because of the path design problem that the highest point of the ballistic trajectory is relatively low, and objectively it is also conducive to penetration... …”

"After reaching the highest point, considering that the current aerodynamic wing cannot withstand the severe high temperature and load, the head and body are separated..."

"This is the radar telemetry data diagram of the entire power section, and the three dotted lines below correspond to the telemetry data of the Dongfeng 15 missile, Long March 2 rocket and Dongfeng 21 missile at the same stage after launch. It can be seen that it benefits from the new liquid rocket engine , and greater initial energy, so the verification projectile can reach the same speed and height faster than the latter two..."

"..."

Chang Haonan basically passed by during the flight.

For non-technical people, there are not many points to pay attention to in this part.

The point is still at the end.

"After the nose and body separated, the warhead began to lower its altitude and started its terminal acceleration engine at an altitude of about 55 kilometers, eventually reaching the expected terminal speed of 2530m/s, which is equivalent to a terminal speed of approximately Mach 7.5."

Finally, Chang Haonan took out the terminal trajectory map taken by the shooting range and processed by some technology.

A dazzling white line stretched across the middle of the picture.

But it was as if a laser beam was tilted into the invisible water surface.

There was an obvious "refraction" in the air.

"Oh..."

As expected, there was a burst of exclamation from the audience.

Although the sound was not loud, it was obviously a very obvious reaction for a leader of this level.

And Chang Haonan took this opportunity to deliver another heavy hammer at the right time:

"It is worth mentioning that this very compact solid rocket engine comes from the 11th Institute of the Sixth Academy of Aerospace Science and Industry, and is planned to be used as a payload booster for my country's intercontinental missiles with multiple independently targetable reentry vehicles in the future..."

In the previous moment, the leader was obviously ready to ask something.

But he was blocked in his throat by the second good news that followed.

For a moment, he didn't even know which question to ask first.

As for the other big guys, their eyes were flashing with different lights, but it was obviously not their turn yet, so they were not in a position to speak.

In the end, curiosity prevailed over the chief --

Although intercontinental missiles and MIRVs are national treasures, they are not new.

But he had never seen the scene in the picture.

"Is the change of direction of the missile in the air the effect of the radar imaging guidance component that you told me about before?"

The chief pointed to the picture in front of him.

"That's right."

Chang Haonan nodded obediently:

"At an altitude of about 85 kilometers, the synthetic aperture radar seeker was activated, identifying the target that best matched the signal characteristics of the aircraft carrier within the field of view, and then controlling the flight attitude of the warhead to turn to the target direction."

"Because this recognition process is relatively complicated, the missile-borne communication system cannot transmit all the data back to the ground, but it can still be seen from the final hit effect that the seeker itself and the target recognition algorithm have achieved the predetermined design goals."

As he spoke, the picture on the screen switched to a photo taken from the air this morning.

Among the dozen or so targets, the missile accurately selected the one closest to the aircraft carrier.

With the psychological preparation before, this time, no one exclaimed.

But from the actions of the audience, it can be seen that the shock brought to them by this scene is no less than before.

In particular, a leader in a naval uniform opened his mouth slightly, his deep eyes motionless, quietly staring at the charred mark almost in the center of the "aircraft carrier deck".

It seems to have returned to the not-so-good spring ten years ago.

"Thousands of troops crossed the strait, and the waves opened the way..."

He couldn't help sighing in his heart:

"If there were such conditions at that time..."
