Chapter 921 Ask for yourself
"Not only has the power, it has a high density, the impact sensitivity is lower than that of RDX and HMX, the friction sensitivity is similar to that of HMX, the thermal stability is 5s burst point of 323 degrees Celsius is stable than that of RDX Much, almost the same as HMX, that is, it is worse than TNT, with a melting point of 110 degrees Celsius slightly higher than boiling water, which is easy to melt, but it will not melt under normal circumstances... This is born with the best explosive! This thing looks like it, It can even..."
When talking about this, the comrade who was engaged in the missile was a little unsupported and turned his head skeptical. "Leader, is this thing really reliable? It's not that I don't believe in comrades, but this span is really a bit big. I feel it when I look at it..."
Not blame him for being confused , Black Sorkin (RDX) is already a high-energy explosive. Oktokin (HMX), which is taller than Black Sorkin, goes further and is almost the most powerful stable explosive at present.
Then I suddenly found that I had a new explosive with better performance than HMX, and lower convenience and environmental requirements than HMX. It was normal for me to feel a little unsupported.
There are only some simple parameters on it, but the synthesis process and route have been removed, so it is impossible to tell whether it is feasible.
Hearing his words, the leader of the Defense Work Committee laughed: "Well, you don't have to worry about this issue. Although this thing is just a theoretical design, the technology source, reliability and possibility of implementation are very high. ”
”Theoretical design? In other words, the explosive called DNTF does not exist yet? Then how do these parameters come out?” The comrade who was engaged in missiles was a little anxious, it didn’t sound like it. It's reliable.
"The technology proposer calculated that this is probably the case. But again, you don't have to worry about the reliability of the technology source, remember your dimethylhydrazine fuel combination and dimethylhydrazine Where did the synthesis process come from? ”
The leaders of the Defense Work Committee are not in a hurry at all. If you are confused about this matter, everyone will be confused, but if you come from Gao Zhendong, you don’t need to be confused. It doesn’t matter whether you are confused or not. Just say whether you believe it or not.
DNTF, a high-energy density compound, has a big name when you hear it, and it is possible to leak secrets, so there is only the abbreviation of DNTF in the material, but there is no full name.
3,4-bis(nitrofurozola)furozola oxide.
This thing was not as famous as the famous CL-20 (a total nitrogen anionic salt) explosive in Gao Zhendong's previous life, but in fact, this thing is the same as the CL-20. Look at this thing The structural formula shows that except oxygen, there is almost only nitrogen.
As we all know, nitrogen has a good temper, but the nitrogen in the compound has generally not good temper, and the larger the quantity, the worse it is.
Moreover, the synthetic raw materials are easy to obtain, the synthesis steps are simple, and can be done in 4 steps, and the yield is not too low.
The most nervous thing is that this thing is actually synthesis steps and basic processes on Gao Zhendong's network in his previous life.
It just so happened that Gao Zhendong knew that there was a solid propellant that was used for this thing, so that wasn't that a coincidence.
After listening to the leaders of the Defense Work Committee, the comrades who were engaged in missiles almost immediately let go of their hearts. So where is it? That's fine, it seems to be very feasible.
They now remember the feeling that the dimethylhydrazine/nitrogen tetroxide fuel combination brought them the feeling of "the mountains and rivers are full of roads, and the willows and flowers are bright and bright" and the other party's suggestion of the skeleton The dimethylhydrazine synthesis process has extremely high maturity and availability.
It is also a very happy thing to have such a comrade helping outside.
Although he didn't know who or where this comrade who had been with God for a long time was, that didn't matter.
It is important that everyone work together to strive for a goal. "Ah, then I understand, hahaha." The comrade who was engaged in the missile opened the second one happily.
There are still only some parameters, but nothing about the synthesis route.
There is still only one abbreviation, B-GAP, which involves more physical and chemical properties. However, this comrade who is engaged in missiles is not an engine, nor a propellant. Many of them don’t understand it very well, but at least there is He can see a few things clearly.
B-GAP is actually the abbreviation of branched polyazide glycidyl ether. You can tell at a glance that it is also nitrogen, an energy-containing explosive sticky with high density, high energy content and good mechanical properties Conjugate.
"...The mixed explosives with B-GAP as the energy-containing adhesive increase by more than 1400kJ/kg per unit explosion heat compared to the mixed explosives of the same formula inert adhesive agent..."
This article can show the benefits, and there is no need to say anything else. High explosive heat means higher energy. Unit explosive heat of 1400kJ is not a joke. For example, the explosive heat of TNT is 4400kJ/kg.
"…The glass transition temperature is low, the sensitivity is low..."
Low sensitivity means that the environmental conditions are required during processing, and the difficulty and risk of processing and use are reduced.
Don't underestimate this little change. The Nobel Prize was born by reducing the risk of storage, transportation and use of nitroglycerin explosives. Otherwise, Nobel would not make a fortune, so naturally he would not have Nobel Prize.
Thinking about this, the comrades who were engaged in missiles felt that this matter became more and more advanced in an instant.
The rest is much simpler, just like a little boy with firecrackers in his hand and cow dung in front of him, it is natural.
What are you doing when you stand there? Use B-GAP to stick DNTF and other explosive components!
The third piece of materials that the comrade who was engaged in missiles saw was not all these two things, and there was a little something else. This thing called GAP ultra-high energy propellant has nothing else in it, such as B-GAP, RDX, DNTF, and these three things.
Because of the excellent mechanical properties of B-GAP, the content of B-GAP accounts for only 10% of the propellant, which is a very impressive result.
In fact, Gao Zhendong directly crossed the NEPE propellant, which is also an energy-containing adhesive, and directly used GAP propellant. The reason for this has nothing to do with the advanced nature. It mainly depends on two reasons.
First, the information he had seen in his previous life was GAP. NEPE had not been systematically viewed because it was not new enough and he had not seen it, so the system naturally could not be generated.
Second, GAP propellant is actually a simpler formulation than NEPE, and it can even require plasticizers.
As for the comparison, NEPE and GAP are both at the same level. GAP is only better in mechanics, physics and chemistry, and potential, but comparison is the one that is far more than 25% higher than HTPB propellants. .
This comparison, for Gao Zhendong, not doing GAP is a fool.
In fact, this is the same as when he doesn't engage in CL-20 but DNTF. Both are at the same level, but he doesn't have CL-20, but he has DNTF.
For comrades who engage in missiles, this GAP propellant does not require any other reason, just one thing can make his eyes straight.
Compare the rush!

A ratio of at least 2500Ns/kg is irresistible.
You should know that before this, the highest solid propellant specific impulse they could see was no more than 1800Ns/kg. The highest specific impulse of practical inert adhesive propellant is probably 2100Ns of HTPB About /kg, you can't get up any further. Of course, theories can be even higher, or add some aluminum, ammonium perchlorate and other things.
The GAP propellant taken out by Gao Zhendong is undoubtedly shocking to the eyes of comrades who have never seen even HTPB propellant.
I would be sorry for the two emperors Yan and Huang, the ancestors, and countless revolutionary martyrs!
The increase in range of this thing is not a linear increase, but an approximately exponential level. Moreover, this improvement effect is more obvious to missiles with a longer range, and intercontinental missiles get it from it. The benefits are more than medium-range missiles.
Roughly estimated, this is from 1800Ns/kg to 2500Ns/kg, with a 38% increase in specific impulse, and the same weight of propellant can bring about 80% range improvement.
And the density of this propellant is too high! It can reduce the volume at the same weight.
Which missile comrade can withstand the test of this propellant?
What solid engines can't be done, what's the range is too long and it won't be accurate, go first!
We must use this propellant!
Seeing the increasingly excited expressions of the comrades engaged in missiles, the leader of the Defense Work Committee smiled and said, "How is it? Do you feel a little confident now? Hahaha."
"Yes! Yes! I don't believe this thing anyway. If this is true, can't we come up with a good missile?"
As long as the range is solved, the accuracy is Well... I have said it before, it almost happened.
"Will the liquid guy still do it?" asked a comrade.
This matter has stopped everyone from asking about it.
Say not to do it, what if the progress of solids is slow?
It seems a bit wasteful to say it?
The chief engineer of the Defense Work Committee laughed: "Let's do this, I've prepared it. We have invited the researcher of this solid propellant to come over and wait for the phone in another conference room. Follow It is stipulated that you can't meet, but it's okay to call and communicate in person."
With the experience of the last similar meeting a few months ago, he is now smart. This matter has a lot to do with Gao Zhendong, so I will invite Gao Zhendong over and wait.
The comrade who was engaged in missiles was overjoyed when he heard this. Hey, he asked himself what the expected progress was.
At this time, Gao Zhendong was waiting calmly in another conference room. When the phone called and heard the question of the comrade who was engaged in missiles, Gao Zhendong smiled and said, "The speed of this solid propellant is not allowed. , it should not be slow. Although the reactants, additives, catalysts, reaction conditions and reaction processes at each step are not very careful, they only lack some detailed conditions and require experiment determination and optimization, but I am confident about this synthesis line. , there is no problem. "
What can I have? It was originally a paper from my previous life, and the things in it were very detailed.
"As for the solids you mentioned just now, whether to make liquids, my personal suggestion is to walk on both legs and do both solids and liquids."
"Ah? Isn't this cost too high?" The audience was in an uproar, and even the leaders of the Defense Work Committee could not bear it. This kid was really greedy when he was greedy.
