Chapter 1336 The Fate of a Propellant

After hearing this bad news, Lin Chenggang's fingers trembled unconsciously.

The mouth opened first, obviously what I wanted to say.

But soon closed again.

After all, I really couldn't think of what to say for a while.

Why is this?

I joined the favorite project for the first time, and I found the research direction that suits them. Two happy things were rearranged together. What I got should have been like a dream in a dream ... but why, it will become like this ...

After half a day, I finally appeared in a tone:

"ah?"

Thousands of words are concentrated in this short word.

"Cough--"

Looking at Lin Chenggang, full of dull faces, Chang Haonan's heart also gave birth to a little guilty sense, and cleared his throat embarrassingly:

"Originally ... because the inhalation hypersonic speed scheme is still in the early stage of progress, and the decision of this modified design has just been made, so we plan to announce it at the next all technical seminar ..."

"I just did not expect that Comrade Cheng Gang also happened to have some new progress ..."

"..."

In fact, this explanation is completely reasonable.

Although the core management is only a dozen people who seem to be not much, the entire hypersonic weapon project involves almost half of the military system, and the person in charge of the first -level subsystem of Lin Chenggang is nearly three digits. If It is even more difficult to count the second and third levels.

Such a huge -scale project team, considering confidentiality issues, the upload of information is inevitable.

Many times they are completed through regular reports and internal meetings.

It is not after the above decision is made, and everyone can be notified the next day.

If Chang Haonan can know Lin Chenggang's operation early, maybe you can also make some psychological construction for the other party in advance.

The decision of developing the CTK series variable thrust propeller on the basis of CT-1 is also derived from a full-time inspiration, and after confirming the feasibility of this technical route, what I think is "I first save the good news. , Wait until the end of the year to report the whole work of Academician. "

As a result, the work was indeed rectified.

Unfortunately, it is two -way.

Lin Chenggang was very clear. In the final analysis, he could only rely on his own luck.

But it is really uncomfortable to be clear and uncomfortable.

"Academician Chang ..."

For professional instincts, Lin Chenggang is still going to struggle:

"Although the rocket pushing segment is not the core system of inhale high supersonic missiles, if it can achieve controllable thrust, it can still significantly improve the flexibility of combat ..."

In the end, even he felt a little bit unable to make it.

Increasing flexibility is compared to traditional solid rocket fuels.

Although conventional solid engines can quickly drive the missile acceleration after ignition, the resistance increases at high speeds, which has reduced the speed of the missile at the time of the later taxi. It is also difficult to greatly increase the effective range of effective rocket weapons.

In contrast, the controllable thrust pushing agent can provide power in the early and middle stages, while reducing the energy loss caused by the air resistance. When the end of the end, the sprint sprint accelerates It is not particularly ahead, but it can still bring huge advantages in actual operation.

Moreover, the CTK series promoter itself continues the excellent performance of the CT series, and it is a comprehensive leader in the past.

But if it is compared with inhale power ...

How much is a bit of self -insulting.

In particular, the high supersonic weapon was originally a mapping time to compress the opponent's response time, and there was no need to "use the speed to change the range".

So after a few seconds of stuck, he decided to change his mouth:

"Well ... Although the demand for flexibility may not be very large in the hypersonic missile, the requirements for the starting speed of different models and range of the range of different models and range are also different. Using different control logic can meet different tasks, thereby reducing research and development and production costs ... "

Compared to the paragraph just now, the reason for this time is indeed more reasonable.

But not many.

Chang Haonan waved his hand to prevent Lin Chenggang, who was a little panicked:

"If you consider cost issues, the prices of high -purity nitrogenine and three -dimensional polyethylene glycols in your pushing agent are not low, and the preparation process is relatively complicated. I am afraid there will be no particularly obvious advantages."

Although he is also distressed by the other party, the matter at the project level still has to make as little subjective judgment as much as possible:

"The main thing is that the new dual -modal stamping engine can achieve a combination of sub -combustion and super -combustion, so it only takes about 2.5 Mach's threshold speed to start normally. After breaking the next critical value , So you can achieve a certain task flexibility by adjusting the proportion of two stages of working time ... "

Now, Lin Chenggang has nothing to say.

What is the dimension reduction blow?

This is equivalent to your cold windows for many years and finally get a junior high school, but as a result, the news that Qing Dynasty had died in the distance.

"However, Comrade Cheng Gang, don't be too deadly."

At this point, Chang Haonan decided to encourage this unlucky subordinate:

"I have seen the test data of CT-1 propellant on several types of air defense missiles. It can be said that it even exceeds my idea when I first proposed the concept of mixed propellant to a certain extent, and fully meets our needs for rocket boost."

"Moreover, as the threshold speed decreases, the booster can also reduce its volume accordingly, thereby improving its compatibility with launch platforms, especially air-launched and submarine-launched platforms."

So far, except for the three ballistic missile submarines 406, 409 and 200, the Chinese submarine force has no other models equipped with vertical launch systems.

The torpedo tube caliber, which is usually only 533mm and no more than 650mm, obviously limits the size of submarine-launched weapons to a considerable extent.

At least the air-breathing hypersonic missile designed in the initial version could not be inserted because the booster size exceeded the standard.

No mistakes in one song, one launch, one content, one book, one forum, one 6, one 9!

And for the same reason, it is difficult for tactical aircraft such as the J-11 to carry it, so it was originally planned to be equipped to naval destroyers and air force bomber units first, and then develop sub-models for land-based and submarine-launched launches.

Now a lot of trouble has been saved in the future.

Zheng Liangqun will probably be very happy after hearing this...

"In short."

Chang Haonan concluded:

"Your contribution will definitely be reflected in our results, and will not be ignored by comrades."

Hearing this, Lin Chenggang, who was originally as pale as death, finally regained some spirit.

Although CT-1 was developed almost completely according to the ideas given by Chang Haonan, it is still his achievement.

It can be used in the superb project, at least it is not in vain.

"Then this CTK series propellant..."

He asked tentatively.

Although a round of experiments with a decent success rate have been carried out, in order to truly promote this new technology to large-scale application, more resources and time are bound to be needed.

If the superiors are unwilling to support, then he can probably only persist until the end of the technical verification stage by himself.

Fortunately, what Chang Haonan lacks the least is resources.

As for time, he can also ask the Torch Laboratory to provide some help to speed up the research progress.

On the other hand, Yao Mengna's maternity leave will end soon, but she is still breastfeeding. I am afraid that it will be inconvenient for her to go in and out of the workshop for a long time in the future, and she may have to take over some of the computing work.

And this kind of research content related to electrochemistry can be said to be the most suitable field for computational materials science to play a role.

Therefore, Chang Haonan immediately made the decision:

"Continue the research and increase the investment!"

"Although the dual-pulse design itself is not a particularly new concept, the previous technical route all used pulse isolation devices, which inevitably affected the engine performance and reliability, and it is completely incomparable with this new idea... I will send a letter to the Industrial Construction Committee in the name of the general consultant later, asking them to cooperate with your work and increase the priority of investment in the research and development of new propellants."

"In addition, considering that the problem of the rocket booster stage has been basically solved, I approve that you can directly participate in the research and development of those air defense weapon models. Of course, you are still listed in our project team, so you don’t have to worry about this..."

"..."

Half an hour later, Lin Chenggang left Chang Haonan's office with a thin letter of introduction in his hand.

Standing in the summer sun in Beijing, he suddenly felt a little unreal.

How can I, a member of the hypersonic weapon research and development team, go to work on air defense missiles...
