There's a rumour, that most feudal research centers and big weapon producers around the world don't like these two guys...

Why... are they not trustworthy or do they think so much outside the box it annoys the old guards?

There is no box... For 60-80 years after the HTPB was invented, this is the first real innovation. Old guards, capable of innovation, are already retired . The new ones are utterly incapable of any innovative thinking, they lack not just the scientific knowledge needed, but worse, they lack fantasy and inspiration.

And when somebody comes with innovation he/she immediately becomes the bad guy.

From this presentation, slide 3, only the upper left corner (H-TBX).

https://www.researchgate.net/publication/341043213_SOLID_STA...

The competition is fierce, completely incapable of innovation but quite capable when it comes to criminally hacking into someone else's computer, lobbying, etc...

Your presentation is impressive... maybe it’s lost in translation but I find your negativity discouraging.

Your product seems to be superior, at an excellent cost... so I do not understand. I know, the field of military energetic is very slow, they don’t like change...CL-20 has been researched for 30 years now with hardly any application.

What is your outlook on the industry as a whole? Have your tried to sell your product to other militaries?

Does the aluminum in your composition react, as fast as in combined effect explosives (7 expansions)?

From experimental data we have brisance and metal acceleration equal to TNT. The Al is optimized to burn during the positive phase of pressure, which is 10s of expansions, see article. Please all similar questions on U2U so we do not spam the topic.

H-TBX is a bad idea. The content of the fireball doen't magically mix with the air. You have to put the fuel on the outside to ride the shock, hence A-TBX.

"""The content of the fireball doesn't magically mix with the air. """

Extremely wrong! The solid heavy Al fuel particles always tend to go to the oxygen rich periphery.

A-TBX is indeed better in air blast, but with zero brizance, unfortunately.

I like how in the second video there is a women in traditional dress helping with the ribbon cutting. A very beautiful dress? Are those common in your country, my friend who was polish had one for dance... looked very similar.

The next publication on the topic - as a "conference proceedings". Submitted to PEP as well, before 5 days. Interesting chemistry is discussed. Like how SiO2 catalyzes the combustion of Al.

Butterfly effect in the military industry and intelligence community.

Butterfly flapped its wings:
https://onlinelibrary.wiley.com/doi/full/10.1002/prep.202100...

The equivalent of 2 multiplied thousand times and somebody on the other part of Tsarigradsko shose Blvd. got 112 millions USD.

Butterfly got thousand times less. But the next wing flap may cause a tornado...

Would this be a theoretically good partial approximation to a pure fuel/air explosive?

Just dissolve N2O into say only diesel fuel with Al/Fe shavings plus another more volatile fuel that does not mix with diesel containing a suspension of very fine aluminum powder, where the N2O part is to be detonated with a high-end detonating charge.

Simple, powerful, very hot, but only partially a successful FAE?

Note, pure N2O based explosions are notoriously known for extreme high temperatures, in fact, when a transport truck containing N2O are involved in an accident, most of the pertinent direct metal evidence has been vaporized per reports of accident scene investigators.

The logic here is that the extreme temperature of the 1st explosion fire ball sprouting burning metal particles would mitigate the 'timing' problem associated with the ignition of the FAE mix part.

Should be spectacular to observed even in small quantities.

At 40 Celsius, 10 atmospheres, it takes 140 grams of Dodecane to dissolve about 9 grams nitrous oxide.

“Notoriously known for extreme high temperatures” my ass. That mixture is hardly going to do anything different from normal diesel oil full of metal shavings.

I’ve seen you post a ton of theoretical reactions, and then I look at the sources you give and yes, the reactions really happen, but only in trace amounts. Please keep this in mind, especially when it comes to suggesting means of creating bulk reagents or energetic materials. You can use some obscure free radical chemistry to put 5ppm, or even 6% of the most flammable/explosive shit ever into a bucket of inert precursors, but that’s meaningless since your concentration won’t sustain ignition.

How? How does that burn hot? It’s two double bonded nitrogen and one oxygen?
