Well, so it exceeds, in the screenshot that I dropped above, it can be seen that its detonation velocity is 8110 m/s. In other sources, I found speeds
of 8350 at 1.72, which is quite consistent with 8110 at 1.7
As for the detonation rate in plastic explosives, it may well be even higher than in powder ones. Because of the greater continuity. Exactly the same
works for watered-down explosives. Urbanski wrote about that, too. And I even remember, I think the Japanese, in some study "accelerated" tetryl
thickened with water with dissolved ammonium nitrate to 8500 m/s instead of 7600 characteristic for it
There was such a plastic explosive.
"Performex -79P" PETN– 79%, dibutyl phthalate — 13%, nitrocellulose – 8% Detonation rate
7850 m/s at 1.50 g/cm3. It is used for explosive hardening of metal and repair of blast
furnaces.
Pure pressed PETN at 1.51 g/ml yields 7520 m/s.
In fact, the biggest problem is that different sources from the beginning of the twentieth century to the present used different measuring equipment
and different measurement conditions. So the exact detonation speeds can easily differ by 300-500 m/s. In such old books as Stetbacher or
Khmelnitsky's reference books, they indicate 8400 m/s at 1.6, which is obviously not the case.
