Re: Any official studies of Hybrid Cannons?

Perhaps you should associate the physical phenomena that occur in a hybrid, with machines that produce mechanical energy in the same way, but that are something else, for example an internal combustion engine. It has there, a fuel, air, a spark plug and an explosion, in a cylinder. Imagine a motorcy...

Two Italian WW2 helmets found

Now I am hooked.. Yesterday I found two Italian WW2 paratrooper helmets on a slope of a local mountain. This region where I live was under Italian military occupation from 1941 until Italy capitulated in 1943. Judging by the shape, I am pretty sure they were manufactured for paratroopers. My grandfa...

Re: Hybrid disk burst pressure effect on performance

You need something to induce turbulence! Some experimentation was definitely in order, so I machined a Delrin cup to fit the chamber with a 1/4" orifice through the base: 20231206_213324.jpg baffling.png I fired a series of shots and the results were quite interesting.

Hybrid handgun with rupture disc

I had this project in mind for quite some time, and I have finally finished it. This is this .22 caliber pistol that fires common pellets, associated with a rupture disc. The advantage is that the weapon can be supplied in the same way as a common, commercial compressed air gun. It has an inverted l...
