Chapter 1336 The fate of a propellant
After hearing this bad news, Lin Chenggang's fingers trembled slightly unconsciously.
My mouth was opened first, obviously wanting to say something.
But it closed again soon.
After all, I really couldn't think of anything to say for a moment.
Why is this happening?
I joined the project I like for the first time and found a research direction that suits me. The two happy things overlapped together, and I should have been happy time like a dream... But why, It turned out like this...
After a long time, I finally put on a tone:
"Ah?"
Thousands of words were condensed into this In a short word.
"Ahem——"
Looking at Lin Chenggang with a dull face, Chang Haonan felt a little guilty in his heart, and he cleared his throat awkwardly: "What are you... …Because the aspirated hypersonic solution is still in the early stages, and the decision to modify the design has just been made, we plan to announce it at the next full technical seminar..."
"I just didn't expect that Comrade Cheng Gang, you happened to have some new progress..."
"..."
In fact, this explanation is completely reasonable.
Although the core management has only a few dozen people, the entire hypersonic weapon project involves almost half of the military system, and the head of the first-level subsystem at the same level as Lin Chenggang has It is nearly three digits, and it is even more difficult to count if the second and third levels are counted.
A project team of such a large scale, considering the confidentiality issue, there are inevitably problems in uploading and downloading information.
It is often done through regular reports and internal meetings.
It is not that everyone can be notified the next day after the above decision is made.
If Chang Haonan could know Lin Chenggang’s operations in advance, he might be able to make some psychological construction for the other party in advance.
The decision to develop the CTK series variable thrust propellant based on CT-1 also came from a very accidental inspiration. After confirming the feasibility of this technical route, the latter thought "I Let’s save the good news first and wait until the report is at the end of the year to give Academician Chang a whole big job.”
As a result, the big job was indeed completed.
It's a pity that it's two-way.
Lin Chenggang knew very well that in the end, he could only rely on his bad luck.
But no matter how clear it is, it is really uncomfortable.
"Academician Chang..."
For the professional instinct, Lin Chenggang was still ready to struggle:
"Although the rocket booster section is not considered an aspirated hypersonic missile. The core system, but if it can achieve controllable thrust, it can still significantly improve combat flexibility..."
In the end of this, even he himself felt a little unable to make up.
Improve flexibility, that's compared to traditional solid rocket fuels.
Although conventional solid engines can quickly promote missile acceleration after ignition, high speed causes a surge in resistance, which causes the missile speed to rapidly decrease when gliding in the later stage. This principled defect determines that even if the propellant performance can be improved, it can be improved. And the overall design level of the engine, it is also difficult to significantly improve the effective range of effective conventional rocket weapons.
In contrast, controllable thrust propellant can provide power in a long and thin and flowing manner in the early and middle stages, while reducing the energy loss caused by air resistance. Wait until the end to accelerate again, even if it is a comparison. The paper parameters are not much ahead, but they can still bring huge advantages in actual operation.
What's more, the CTK series propellants themselves continue the excellent performance of the CT series and are even ahead of the past models in all aspects.
But if compared with the inhaled power...
It's a bit of a humiliation.
Especially hypersonic weapons are designed to compress the opponent's reaction time at the limit, and there is no need to "change the range with speed".
So, after a few seconds of stuck, he decided to change his words: "Okay... Although hypersonic missiles may not have a great demand for flexibility, they are different models and ranges. The requirements for start speed of aspirated power are also different. We can design a general boosting section, which can meet different task requirements as long as different control logic is used, thereby reducing R&D and production costs..."
Compared to the previous paragraph, the reason this time is indeed more reasonable.
But not much. Chang Haonan waved his hand to stop Lin Chenggang, who was a little panicked: "If you consider the cost issue, the high-purity hydroxylamine nitrate and three-dimensional porous polyvinyl alcohol needed in your propellant are not cheap. Moreover, the preparation process is relatively complicated, so there may not be any particularly obvious advantages. "
Although he felt a little sorry for the other party, he still had to do as little as possible at the project level. Subjective judgment:
"The most important thing is that the new dual-mode ramjet engine can achieve the combination of sub-combustion and supercombustion, so it only takes about Mach 2.5 to start normally, waiting for the next criticality to break through After value, switch to the supercombust mode, so you can achieve certain task flexibility by adjusting the ratio of working hours in the two stages..."
Now, Lin Chenggang had nothing to say.
What is a dimensionality reduction strike?
This is equivalent to having studied hard for many years and finally becoming a Jinshi in high school, but you heard the news that the Qing Dynasty had died from afar.
"But, Comrade Cheng Gang, don't be too discouraged."
At this point, Chang Haonan decided to encourage this somewhat 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 surpassed my first idea when I proposed the concept of mixed propellant, which is completely in line with our support for the Rockets. ”
” Moreover, as the threshold speed decreases, the booster can also reduce its volume accordingly, thereby improving compatibility with the launch platform, especially the air-launched and submarine-launched platforms. ”
So far, except for the three ballistic missile submarines, 406, 409 and 200, the Chinese submarine force has not had any other models equipped with vertical launch systems so far.
The torpedo tube diameter, which is usually only 533mm and not more than 650mm, obviously limits the size of submarine-launched weapons to a considerable extent.
At least the initial version designed superb suction type cannot be inserted because the booster size exceeds the standard.
No mistakes, one song, one content, one in 6, one book, one bar, one reading!
And for the same reason, it is difficult to carry tactical aircraft like the J-11, so it was originally expected that it would be given priority to naval destroyers and air bombers, and then specialize in land-based and submarine-based launching Sub-model.
Now, it saves a lot of trouble later.
I guess Zheng Liangqun will be very happy after hearing this...
"Anyway."
Chang Haonan concluded: "Your contribution will definitely be reflected in our achievements and will not be ignored by comrades." Hearing this, Lin Chenggang, who was originally ashamed, finally Rejuvenate some spirits.
Although CT-1 is almost completely developed according to the ideas given by Chang Haonan, it is still his achievement.
It can be used in superb projects, at least it has not been in vain.
"Then this CTK series propellant..." he asked tentatively.
Although a round of experiments with a fair success rate has been conducted, it is bound to require more resources and time to truly promote this new technology to a large-scale application.
If the superior is unwilling to support it, he may have to persevere until the end of the technical verification stage.
Fortunately, Chang Haonan’s most lacking in resources.
As for time, you can also ask Torch Lab to provide some help to speed up the research progress.
On the other hand, Yao Mengna's maternity leave is about to end, but she is still breastfeeding. I am afraid that it will not be convenient to enter and exit the workshop for a long time in the future, and it is very likely that she will take over some of the calculation work.
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.
So, Chang Haonan immediately made a decision: "Continue to research and increase investment!"
"Although the dual-pulse design itself is not a particularly new concept, the technical routes in the past have used pulse isolation devices, which inevitably affects engine performance and reliability, and cannot be compared with this new idea at all... I will do it later In the name of the general consultant, ICBC will send a letter to them to cooperate with your work and increase the priority of investment in the research and development of new propellants. "
"In addition, considering the problem of the rocket boosting section It has been basically solved. I approved you to directly participate in the research and development of several air defense weapons models. Of course, the name is still 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 the capital, he suddenly felt a little unrealistic.
Why is my hypersonic weapon development team going to build air defense missiles?
