The military-industrial scientific research system of the academic master.

Chapter 1236: A Changing World

These discussions, which either took place in cyberspace or on the other side of the ocean, had not yet reached Chang Haonan's ears.

After confirming the missile hit early in the morning on New Year's Day, he rushed back to Haojing, completed a report as quickly as possible, and then flew directly to the capital.

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

The targets at the Longyuan Effect Test Range were indeed camouflaged during their construction, but the traces left after being hit could not possibly escape subsequent satellite reconnaissance.

Even if other confidentiality measures are 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.

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

The key is to ease the flow, not to block it.

Therefore, in fact, at the beginning of the planning of the hypersonic verification missile, preparations had already been made for this...

……

January 2006, 1, the first day of the Lunar New Year.

Beijing, evening.

It was still the Jingxi Hotel, and still that not-so-big conference room.

However, the situation is different from 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 including several high-level leaders.

Obviously waiting for him.

"Comrade Haonan."

The chief sitting on the sofa in the middle showed a kind smile, with no trace of his former fame:

"We have been waiting for the good news you brought since last night!"

Faced with this situation, Chang Haonan quickly quickened his pace and walked up to the podium:

"I'm really sorry, due to weather problems at the shooting range, the helicopter took a slightly longer route to ensure safety, so it was a little late."

As he spoke, he signaled to the staff next to him to start operating the equipment, preparing to project the report onto the screen.

In fact, there was no problem with the weather conditions at the shooting range.

The helicopter didn't take a detour either.

In fact, Chang Haonan was not late at all.

But you can't say it's the leader's fault. Shouldn't he have come so early?

So we can only attribute it to force majeure.

This way everyone can save face.

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

“Good things eventually come to fruition. As long as the result is good, why not wait a little longer?”

With just one sentence, the originally tense atmosphere on the scene immediately relaxed.

Just at this moment, the cover of Chang Haonan's report appeared on the curtain behind him.

"Then, my dear leaders, let me report the final results of this hypersonic verification missile test..."

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

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

The entire report is quite long, nearly seventy pages.

But these high-level leaders are busy with all kinds of affairs, so it is obviously impossible for them to start from the beginning when Pangu created the world.

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

It was taken by a camera installed on the side of the bomb bay of Figure 41175, No. 160.

The perspective is slightly overlooking, and you can even vaguely see the lights of thousands of homes in the city in the distance.

In the center of the picture is the missile that has just left the launch pad but has not yet ignited.

"First, during the missile launch, we successfully demonstrated that the spoiler + trailing edge tilt design can significantly improve the air flow under the shallow cavity bomb bay."

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

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

"After being pushed off the rack, the verification missile only had a small longitudinal swing. Before the final ignition, it was at an elevation angle of about 10 degrees, which is just conducive to the maximum range of most missiles. This technology can also be applied to the bomb bay of stealth fighters to ensure that smaller airborne weapons do not lose control of their attitude during supersonic departure..."

The opening was such a heavyweight content that it obviously caused some commotion among the audience below.

But the leader did not rush to speak, but signaled Chang Haonan to continue.

"The subsequent accelerated climbing process, apart from having a certain initial velocity and altitude, is not much different from the common ballistic missiles we used to use. It's just that due to the path design, the highest point of the trajectory is relatively low, and it is also objectively conducive to penetration..."

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

"This is the radar telemetry data of the entire power stage. The three dotted lines below correspond to the telemetry data of the DF-15 missile, the Long March 21 rocket, and the DF- missile at the same stage after launch. It can be seen that thanks to the new liquid rocket engine and greater initial energy, the verification missile can reach the same speed and altitude faster than the latter two..."

"..."

Chang Haonan basically just passed through the entire flight process.

For non-technical people, there is not much to pay attention to in this part.

The key point is still at the very end.

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

Finally, Chang Haonan took out the terminal trajectory map that was taken by the shooting range and processed with some technical skills.

A bright white line runs across the middle of the picture.

But it was like a laser beam slanting into the invisible water surface.

There was an obvious "refraction" in mid-air.

"Oh……"

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

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

Chang Haonan took this opportunity to deliver another heavy blow:

"It is worth mentioning that this very compact solid rocket engine comes from the 11th Institute of the Sixth Academy of China Aerospace Science and Industry Corporation. It 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 the second piece of good news that followed immediately blocked his throat.

For a moment I 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 got the better of the chief.

Although intercontinental missiles and multiple independently targetable reentry vehicles are important national weapons, they are not new.

But he had never seen the scene in the picture.

"The missile's change of direction in the air is the effect of the radar imaging guidance component you told me about before?"

The chief pointed to the picture in front.

"Yes."

Chang Haonan nodded obediently:

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

"Due to the complexity of this identification process, the missile-borne communication system cannot transmit all the data back to the ground. However, it can still be seen from the final hit effect that the seeker itself and the target identification 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 a dozen targets, the missile accurately selected the one closest to the aircraft carrier.

With the previous psychological preparation, there was no exclamation this time.

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

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

It seems like we have returned to that not-so-beautiful spring ten years ago.

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

I can't help but sigh:

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