First of all. It was impossible for me to upload the PDF file because it is quite heavy, you did it. Excellent!jackssmirkingrevenge wrote:OK, I understand this a bit better now, good find!
pdf link to the study for those interested.
The pressure spike in the secondary chamber really is quite impressive, it looks like this could be a legitimate way of boosting energies from a hybrid without necessarily increasing mix number. If I understood correctly the tests were carried out in closed chambers, which means that having the secondary chamber open to a barrel changes the dynamic somewhat if you are using an atmospheric combustion, but of course in a hybrid you would be using a burst disk.
It is interesting to enhance or give more power to combustion weapons. In my case, my combustion weapons have a retention of ammunition, a neodymium magnet, and it seems to be enough to partially seal the second chamber. There is definitely an increase in energy and change the noise to a small dry sound, and stronger, up there and proven myself. They are small caliber, 3/16 "and 1/4" steel ammunition.
According to my calculation for the penetration power that was observed, they behave like a hybrid of approximately 2X.
I have not tried with a hybrid.
As you know, in those small calibers the power of combustion weapons is very bad ... because the area where the combustion pressure is applied is so small. With this technique I have significantly improved the power, without logically, to the potenmcias of a hybrid that are strong in themselves.
Well, the subject is here for those interested in browsing or developing something like that.
