Chapter 1178 Air-Launched Ballistic Missile

Three days after the meeting of the Institute of Mechanics, official documents regarding the launch of hypersonic aircraft research were also sent to several relevant units.

The entire project is led by the Aerospace Power Group, with the Aviation Industry Group and the Aerospace Science and Industry Group responsible for the specific implementation, and nearly ten other companies and institutions, including the Institute of Mechanics, assisting.

The situation is basically similar to what was predicted in advance.

But because no specific model has been determined yet, there is no such thing as a chief designer at the moment.

Chang Haonan can only temporarily preside over the work in the name of "Director of the State Key Laboratory of High Speed ​​Fluid Dynamics".

Of course, this laboratory actually only exists on paper and does not add any additional facilities or assets.

All members are drawn from each participating unit.

Just to facilitate external communication and internal contact, this somewhat unfocused name was adopted.

Therefore, Chang Haonan had to arrange the first working meeting of the entire team at the Aviation Power Group.

Although it was only a few days later, when I saw Jiang Zonglin again, he was obviously much more haggard than before.

However, his energy levels were maintained well, which was probably just caused by the overload of work these past few days.

"Researcher Jiang, although work is important, you must also pay attention to rest..."

While waiting for other participants to arrive, Chang Haonan took the initiative to speak, intending to catch up with Jiang Zonglin.

After all, for him, the latter is an old acquaintance whom he has not seen for ten years.

Jiang Zonglin was startled by this sudden move, but he immediately realized that it was probably because he was too tired these past few days, which caused his complexion to look bad.

So I quickly rubbed both sides of my forehead to cheer myself up a little:

"Hey..."

"Academician Chang, you are also engaged in research. You should know that we don't have any rest during the critical period... Last time I was finally inspired and came up with some ideas. If I lost my ideas because of a few days' break, the loss would be huge. Big..."

At this point, perhaps to prove that he was still energetic, he also made a joke:

"Speaking of which, I see that you are very knowledgeable and concerned about the work of our Institute of Mechanics. I wonder if it would be convenient for you to provide guidance on the specific work of wind tunnel research and development in the future?"

Chang Haonan, who heard this sentence, spent a lot of effort not to laugh out——

Can you not understand the old work unit from your previous life?

However, he still waved his hand:

"Everyone has a different division of labor. Although I can help a little bit at the theoretical level, at the level of wind tunnel engineering, your experience and ability are more in place..."

There is no doubt that the strength of the Institute of Mechanics is strong enough. Even if there were not enough resources and no support from Chapman-Jouguet combustion theory in the previous life, they still completed the JF12 reproduction wind tunnel and JF16 in less than eight years. Ultra-high-speed expansion wind tunnel.

Now that there is more reliable theoretical and financial support, and the originally planned two-step research and development process has been combined into one, it is obvious that the efficiency cannot be as simple as doubling.

More importantly, the wind tunnel is only one of the basic conditions for hypersonic vehicle research.

Compared with this, there are places where Chang Haonan needs to show his abilities even more...

While the two of them were exchanging polite words, participants from several other units also arrived at the venue one after another.

Although this is the first time that China has launched a formal hypersonic research project, relevant preliminary research has been carried out intermittently for almost 20 to 30 years.

So the representatives present today are at least acquaintances with each other.

Some have even collaborated before.

The person who needs the most introduction is Chang Haonan himself...

Therefore, the warm-up session before the official start of the meeting was quite brief.

Soon we got to the point.

Before the project was launched, the superior unit had already held meetings or reports with several major participants, so everyone understood the basic situation.

Therefore, Chang Haonan first introduced the current status of each technical system.

The key point is precisely the work of the Institute of Mechanics.

Immediately afterwards, Jiang Zonglin also expressed his position to everyone on behalf of the Institute of Mechanics:

"Everyone, the research and development efficiency of the ultra-high-speed wind tunnel will greatly affect the progress of the entire project. Fortunately, we have now received support from our superiors and, of course, our brother units. We will do our best to complete the project within two years. Realize the ignition start of the JF14 recurring high-speed and high total temperature expansion wind tunnel, providing a solid guarantee for subsequent work..."

JF14 is the name Chang Haonan suggested for the new generation of wind tunnel that day——

In the original timeline, the replica wind tunnel was eventually named JF12.

The expansion wind tunnel driven by forward detonation is JF16.

Both names actually refer to the year they were officially put into service.

This was also the case with the later JF22.

But now, the new wind tunnel is scheduled to be put into use around 2007.

Since we already have JF8 and JF10, it is impossible to go back and call JF7.

So simply, (12+16)/2=14...     Of course, Chang Haonan's statement to the outside world is that he hopes to reproduce the role that the JF4 wind tunnel played in promoting my country's hypersonic research undertakings...

After Jiang Zonglin finished his statement, others saw that Chang Haonan did not intend to summarize immediately, so they began to express their opinions as usual.

"Within two years..."

Huang Ruisong, who was sitting in the middle of the conference table, spoke first:

"Academician Chang, should we consider doing some technological exploration based on existing conditions during the interim period?"

Seeing that no one objected to his statement, he continued:

"We have been developing sub-combustion ramjet engines since the early 1980s. Although the middle models have not been equipped with troops in batches, we have accumulated a lot of valuable research and test data, especially in Design area of ​​integral ramjet missiles.”

"If conditions permit, we can first develop a test projectile with a speed of around Mach 4, between ordinary supersonic speeds and hypersonic speeds, and conduct some ground tests..."

However, just when he was halfway through speaking, Zhang Fuzhong, another representative from the Aerospace Science and Industry but belonging to a different research institute, expressed his objection:

"Comrade Ruisong, I understand that you feel sorry for the discontinuation of three consecutive hypersonic missiles back then, but after all, what we want to do is serious hypersonic research..."

"I think you know the difference between sub-combustion stamping and super-combustion stamping better than I do. If we follow your suggestion and start from Mach 4, I believe we can achieve results in a relatively short period of time, but wouldn't that be a success? Are you selling sheep’s heads as dog meat?”

Huang Ruisong was the deputy chief designer of a series of supersonic anti-ship missiles, including the C101, and proposed starting with sub-fuel ramming. Although he did have the idea of ​​​​making up for the regrets of the past, it was definitely not entirely selfish.

Being refuted directly like this is inevitably a bit embarrassing:

"Comrade Fuzhong, although sub-combustion stamping cannot be compared with scram stamping, there is still something worth learning from in terms of structural optimization and control rate design... What's more, there is currently no ultra-high-speed wind tunnel that is actually available. , and we don’t have the conditions to conduct more in-depth research. We can’t just keep doing theory for the next two years, right?”

In fact, Chang Haonan planned to take advantage of today's meeting to deploy the first phase of the follow-up tasks.

I just didn't expect the comrades to be so motivated and start this link in advance.

"Ahem——"

In order to prevent the two people from getting angry, he quickly coughed twice to calm the whole venue again.

"Researcher Huang is right. During the period of wind tunnel development, we cannot remain indifferent... We should carry out some test projects where conditions permit."

Hearing this, Huang Ruisong, who had been tense just now, couldn't help but look happy.

He even glanced specifically in the direction of Zhang Fuzhong,

However, before he could become happy, Chang Haonan continued:

"But according to my idea, it is not to use a ramjet engine... but to use a rocket engine for direct flight testing!"

? ? ?

This time, it wasn't just the two people who had just been involved in the dispute.

Even the faces of other representatives showed a slightly confused look——

Use rocket engines.

Do flight tests.

So isn't this equivalent to firing a ballistic missile?

The second artillery is already equipped with more than ten models, what else is there to test?

"I am indeed talking about ballistic missiles...but not in the usual sense..."

Of course Chang Haonan also noticed everyone's confusion and immediately explained:

"Before the new generation of ultra-high-speed wind tunnels are put into use, the risk and investment of rushing to test scramjet engines are too great, so we can only consider using more mature rocket engines... But compared with conventional models, this new test The projectile will use higher specific impulse liquid fuel, a double-cone layout, and is expected to reach a speed of about Mach 6-7 at the end.”

This completely sudden news caused the scene to fall into silence for several minutes.

Although it sounds a bit outrageous at first, if you think about it carefully, this idea seems very reasonable.

Although the potential of the double-cone layout is not great, the corresponding risks are also relatively low.

The only question is...what to test for?

It's just about two Mach faster than traditional short-range ballistic missiles.

Almost the same as the mid-range guide.

"Will it be modified based on Dongfeng 21...or similar models?"

Facing Chang Haonan, Zhang Fuzhong still didn't feel comfortable questioning directly, so he just tentatively asked:

"Of course it's not..."

Chang Haonan waved his hand:

"In order to enhance the flexibility of launch and give it a certain initial speed, this model will use an aircraft mount to launch from a medium to high altitude."

"In addition, the missile will also use inertial-radar-satellite composite guidance to tactically test the effectiveness of future hypersonic weapons and technically verify its hit accuracy..."
